It seems like KZbin is filled with Commodore videos but little in the way of Atari 8-bit stuff. Let's change that by checking out the condition of these 6 machine so I can determine which will be featured on future repair episodes.

A little tid-bit -- I noticed on re-assembly the "plaster" 800XL has MT 4164 DRAM. If you know these chips, they are always bad..... and sure enough, I tested them and, if I recall, 4 or 5 were bad. A fresh set of 4164 DRAM and the machine works flawlessly. I'll touch on this "repair" when I work on the other machines with faults. Thanks to those who mentioned the XL machines will go into the diagnostics if there is a RAM fault. That's a pretty nice feature! Remember, if you see MT 4164 RAM (specifically the 64k x 1 bit chips) them pretty much assume that at least some have failed. At this point, It is a safe-bet! (Other sizes of MT RAM seem OK, it's just the 4164 type.)

The "Start" and space bar keys on the 600xl should also be a pretty easy fix(if it is a mechanical keyboard). I usually take the keycap off and spray contact cleaner straight at the "openings" around the plungers. After pushing the plunger many times and waiting for the cleaner to evaporate the keys work like new.

After my first computer an acorn atom the Atari 400 was my first "full colour " computer and was very expensive at £499 here in England. I really missed the full stroke keyboard of the Atom so I did that mod with the keyboard. I think it cost about £150. Eventually I finished up with a 48k memory in it and only had it in that form for about 6 months before getting a 1200 xl and later a 130xe. Oh the money I've spent on expensive Ataris...and every one of them played star raiders perfectly.

The very first computer I ever owned, way back in 1987 or so was an Atari 400 with an upgraded keyboard exactly like the one you have. I still have one key from it. If I remember correctly it was dropped and broken, and back in the day I didn't know how to fix it. Later, I think what was left of it was lost in a move. You can't have my key... sorry. You can 3d print one maybe. Or maybe you can have it. It isn't the reset key though. I have kept that key all these years... crazy. I got a 800xl not long after then an 800 and C64's etc., but always loved the design of the 400. I really liked the design of the Timex Sinclair 1000 too. I had a couple of those.

I ran an eight bit Atari BBS for many years till I finally moved it to a PC. I had a 130 XE with a huge memory expansion and had a CSS "Black Box" that had a SCSI interface as well as a printer port and floppy drive adaptors for PC type drives. I used Sparta DOS to run a huge batch file to setup and boot the Oasis BBS, copying a bunch of stuff to RAMdrive so the BBS responded quickly. I started with a 400, got the Cherry keyboard like the one shown, expanded it's memory and installed a speech synth internally, ultimately had it working as an answering machine/ bridge to the BBS.

Adrian Great to see you finally getting round to some Atari 8 Bit machines .. More like the Amiga internally as even more specialist chips than a C64 with Pokey for sound, GITA for the 'TV interface' in PAL NTSC & SECAM versions' ANTIC a secondary CPU devoted to controlling the GTIA chip to get something on screen .. even the CPU has a mod to it as it has an additional line to support working with the ANTIC processor. (and later on FREDDIE to replace logic used for refresh used in later 800XL known as 800XLF and the XE line 65/130/GS these is also a memory management unit a PAL/GAL type chip to allow swapping out RAM for O.S ROM's so a replacement O.S could be loaded under the original ROM chip and swapped in to replace the ROM O.S. this was used in the XL line to provide compatibility with the original 400/800 series. the 130XE used an additional EMMU for bank switching the additional 64K. If you get stuck with circuit diagrams etc. let me know as many online I've found are inconsistant / incorrect, and although I've not produced replacement for all models I have reproduced so for the XE range for my own use. (the 800XL being so very similar) Black screen issue .. "The old Black Screen of Death. Can be quite common amongst 8-bits - they are over 30yrs old tho' there's a couple of questions to ask yourself BEFORE destroying/throwing out/ripping out of your antique: 1. easiest thing to try first - leave machine on for ten minutes....are any ram chips "overheating"? - swap these 2. if the board is socketed, rather than soldered you may have some "unseated" ICs. and check to see if ram, OS Rom, Antic, MMU, PIA, CPU are fully in their sockets. they can look "seated" but may not be. and oxidation/dirt/dust can cause faulty contacts. if your comfortable with doing so, you can remove them and reinsert. deoxit is your friend 3] if still a black screen try this (turn TV volume up): power up using OPTION key, wait five seconds, press SELECT key once, press START do you hear the musical notes? if so your computer is working now press HELP, then SELECT, the START press different keys randomly....do you hear the keyboard BEEPS? these are good signs that atari is fundamentally ok. 4] power supply may be a problem - it may not be supplying 5v. try another PSU. 5] RF or monitor output? if RF, does machine have a channel switch next to the RF output socket? try repeatedly moving it back and forth - it can get dirt inside and cause bad contact. try a monitor cable - these are fairly standard these days and usually come in the form of monitor to scart, monitor to S-video and monitor to RCA varieties. 6] try booting with a Star Raiders cartridge in the slot - If Star Raiders works then ALL three should be good. this should narrow your fault down to PIA, OS Rom, MMU or Ram Jon Halliday [FJC] has also mentioned that the OS Rom should be good too if Star Raiders runs from cart. "This signifies that the cart should be run before the OS is fully initialised. The OS ROM still has to operate well enough to jump through $BFFE, and if the CPU manages to get this far then it's working anyway." thanks Jon - always good to add vital info. " hope this is of some help.

Although there are some basic similarities between the Atari 8-bit and Amiga, I think it's a bit of an exaggeration to call the ANTIC a secondary CPU. Rather, it's the front end of a two-chip graphics subsystem, performing DMA to load graphics data for the back end, which is the GTIA/CTIA chip, to generate the analog graphics signal with. The C64 similarly has a front end and a back end, but it's all on a single chip. One fairly unique thing about the ANTIC is that it has a display list, which is a list of modes to display on each row with a couple of flags to either generate a timely interrupt (DLI) or load an address, but a secondary CPU? Hardly. It can't even change color registers, which is a very common operation on the Atari, on its own--it has to get the actual CPU to do that. Coming from the VCS/2600 (also similar to the Atari 8-bit) perspective, the ANTIC does take the place of the CPU in "racing the beam" to generate the display, so it might seem like a secondary CPU in that respect, but the C64's CPU (and those of most other 8-bit computers, for that matter) doesn't have to generate the display, either, as the VIC-II chip does that on its own. The custom 6502C "Sally" CPU used in the XL/XE series does have tri-state address lines and other features to enable ANTIC DMA, but the C64's custom 6510 CPU also has tri-state address lines to enable VIC-II DMA, in addition to a 6-bit (all the pins that could be spared) I/O port to supplement the I/O ports of the two 6526 CIA chips. The 6510's I/O port is used to control memory bank switching (via the PLA chip) and the tape drive. All 64K of RAM is available except for the 2 bytes used to implement the I/O port (addresses 0 and 1), while on the 800XL, for example, only 62K of the RAM is available, as the memory-mapped I/O address space cannot be swapped out for RAM. By the way, the Atari 400 and 800 do not have the 6502C (except perhaps for their last production runs), but rather a standard 6502 with additional circuitry on the board to support ANTIC DMA. No, I'm not trying to turn this into a contest (I own both computers and other vintage 8-bit computers, and I like them all), I'm just saying there is more similarity than you're implying here, and that most other computers have graphics coprocessors that work autonomously, too. If having a list of display modes (that's why it's called a display list) means the ANTIC is a CPU to you, then OK, but it doesn't mean that in my view. Anyway, great information and advice here, although instead of trying another Atari XL/XE PSU, I would strongly, specifically advise using a better modern one instead. At the very least, one has to know which PSU designs do not have a tendency to fry these vintage computers. I just don't use C64 (and most other Commodore) or Atari 8-bit PSUs at all, because they don't fail safe, they fail destructively. One must always be careful with old PSUs. Even my Apple II PSUs don't get used until I rebuild and test them, starting with replacing the RIFA filter capacitors, of course, and these do not currently have the reputation of damaging the computers when they fail (just stinking up your computer and house for days when those RIFAs blow, and eventually they all do). I for one am just not willing to tempt fate and take the chance for no good reason.

I'm a little astounded at the amount of different 8-bit machines Atari produced over the years. All largely compatible with each other, with only slight improvements between them. They made the 400, 800, 600XL, 800XL 1200XL, 65XE, 130XE, 800xe, XEGS. Commodore at the same time went in so many different directions. The pet line, Vic-20, C64, Plus-4 line, B128, and finally a few compatible machines, the 128 and 128D and a styling refresh of the 64, the 64C. In addition, Atari produced the Atari 5200, which is almost nearly identical to the 8-bit line, but made intentionally incompatible with the 8bit computers because the home computer and the console divisions oddly competed with one another. It tells you something about the different approaches of the different companies. Atari went the route of Apple, and tried to make 8 bit machines compatible with one another. Commodore just kept pushing what worked, and reducing costs of the motherboard, but also going in a bunch of different weird directions. And with all that, and all those computers, Atari got old-sold by Commodore.

Ultimate 1MB, Video Board XE for XL, Stereo POKEY, Rapidus speed upgrade, SDrive Max, maybe even Incognito, SIDE3 cartridge, SpartaDOS X, Fujinet, and more! Atari solved the 1200XL compatibility problems with The Translator boot disk, though FixXL works better. That last 800XL going right to Self Test shouldn't be doing that without a keyboard. Hopefully the PIA or POKEY aren't damaged. The RAM may have some bad chips or the support logic might have faults.

He planned to sell them and I made a deal with him to go through each one cleaning, fixing and upgrading the memory. With NO support from Atari, parts, schematic, or diagnostics I got all the systems up and running and they sold as fast as I got them done. Those were the days!!!

Just so's you knows, even on the XL series keyboards, the Console keys (Start, Option, & Select) are a little special and are read by a different chip from the main keyboard keys. Pokey reads the main keys, and the Console keys & Joysticks are read by the C/GTIA. IMHO, Invest in a FujiNet first, you can use it with any of the 8-bit computers as an SD card-based floppy replacement, on top of the sweet online stuff you can do with it.

close on the history. they wanted to expand on the capabilities of the 400/800 and refresh the lineup so they created the 1200XL. It wasn't trivial for them to go from the 48KB limit to the new 64KB size which was one of the reasons the new OS had too many compatibilities and was too expensive especially with the Commodore 64 out. For a lot of 400/800 software to run on the 1200XL, Atari released a translator but even then, there were still some software that didn't work on the 1200XL. I think part of the functionality of the translator disk was so it made the system look like it only had 48KB so that software worked. So they replaced it with the 600XL and the 800XL which was more compatible than the 1200XL with older titles and also being cheaper. Personally, I loved the 1200XL and it was just so modern and clean looking. It was my first computer. My dad let me pick. I had the Atari 2600 as a pre-K kid. And in kindergarten, our school was full of Atari 800 machines. So I wanted an Atari machine.

I remember in Dec of 1982, I was looking at getting an Atari. I was humming and hawing over which to get. I wanted the 800, as it had the 48K, while the 400 was 16K. A few people who had bought the 400, had upgraded the Memory, and had installed a Keyboard. Once I factor the costs of those upgrades, the price difference wasn't all that great. So I bought the 800 and used it until 1990, when it was stolen when the House was broken into. I did add an 810 Disk Drive, and a couple years later Pooched it by adjusting its Speed in an Attempt to get it to get around some Anti Copying thing on the disks. I replaced it with an 1050 with the Happy Enhancement.

little piece of atari 8 bit trivia. if you had the basic cartridge inserted, and a tape drive (the 410 unit) connected, you could play music from a music cassette with it. the atari controlled its tape drive through a single memory location, location 54018. if you poke 54018,54 in basic with the tape drive connected, it would turn on the motor (which had a play button, but also needed to be activated in the memory to get power to the unit turned on) and turn the speaker on as well. ironically, you could use this same method to load a program from tape without a specific load command. this even worked to test bugs. at one point, i had my atari 400 connected to a reel to reel and stored programs on quarter inch tape. they were very much fun, those machines.

Typing on the Atari 400 Keyboard was miserable. My 400 that I have now, replaced my original 400, looks exactly like the "Mint" one you have. My original one I had had several upgrades to it. First, I painted it entirely black on the outside (forward looking me, now most computers are black). It also was upgraded to 48K RAM via a single board that you just plugged in as a replacement card for the 16K one It had in it (came w/16k). I had a 410 cassette recorder to load tape games that I did copy to disk (Sometimes with hacks sometimes not). It had a B-Key replacement keyboard, like the one you have, or maybe not, but I kept it lubed up with some sort of lubricant, WD40 or 3in1 Oil probably. They did make several of them. It also had one of the joystick ports routed to a side opening for a modem that I had for it that plugged into the joystick port (it was a simple split, the original port still worked). I had 3 disk drives for it, and 810, a 1050, and a Percom DSDD 360K drive. But before the B-Key keyboard, yes, the ends of my fingertips always hurt after a session on my first computer, that keyboard was murder. Ran mine on a 13" Sears TV on a small desk in my bedroom. I was the only student in school with a home computer in my class back in 1980, and two others in the school. One was a Synclair flat looking ZX thing and the other was a TRS-80 Model 1 with a Black & White screen, but it did have a modem, so we could connect via phone to each other. Yes, I had many disks that I "Flipped" over to get to the other 80K of storage that it had on it. I did have one of the "Square Hole" punches. The Atari machines were built like tanks inside, they probably will work forever as long as you take care of them. The 400 I have does still work, and it has several carts for it including BASIC which I was very talented in it's use and did write at the very least two games for it. One was my high school physics projects. It was a game that used several things that allowed you to use your "cheats" (the knowledge of physics equations) to win the game that was about betting on races that you had inside info on about the vehicles power systems they used to propel the machines in the races. Then you could watch the race and see the outcomes of each of the 4 competitors, and of course you could wager your credits on the winner (and win if you did the math right). Not only did I get an A+ on that one, My teacher was convinced to buy an Atari 1200XL at the time (he later Upgraded to an ST as well, I think - before we all went to DOS then Windows machines). Yes, the old girl did me right. Now I'm an Engineer in a Data Center working with HAL... Who could have guessed that? 🤠👍

27:57 That bus connector on the 600XL is slightly different than the one on the 800XL One of the products you could get for the 600XL was a RAM upgrade to give it 64k RAM and effectively turned it into an 800XL. The RAM upgrade needed 5 volts, which is supplied on the bus connector on the 600XL, but the 800XL does not have that pin powered with 5volts. Likely due to prevent damage from people trying to use that RAM upgrade intended for the 600XL to be used on the 800XL. Other uses for that bus connector were SCSI controllers for use with hard drive and whatever else that worked on SCSI 1. A friend of mine ran a BBS on an Atari 65XE with a 20MB scsi hard drive connected to it. The BUS connector port on the XE machines is different (as it's shared with the cart slot) so there had to be an adapter to make it into an XL-style bus port so you could connect devices to it.

This give me hopes for my own collection of Schroedinger's Atari Home Computer Systems. They're my own machines that my brother-in-law took when I moved to California thirty years ago. I'm now looking forward to getting them back from my sister over Spring Break. There's my trusty old late-model Atari 800, which looks good in the photos, the used Atari 400 I got that, if I remember correctly, might have been upgraded to 48K. The Option key looks like someone put out a cigarette on it and the cassette interface doesn't work, but that's how I bought it. The photo shows that it has faded to be almost orange, but the cartridge cover latch is still the original color. It's a later model, too, as evidenced by the fact that it has the GTIA video chip. What I don't see in the photo is the used 1200XL I bought. I was never interested in the later XL and XE Ataris. They didn't seem to be as good or as well-built as the ones I already had. Considering how well the Atari 400s that you have worked, I have high hopes for my own older Ataris. They were very well-built in the early days, before "Mad" Jack Traniel started cutting corners. I just can't wait to see if my old systems, with all their accessories, cartridges, cassettes, and floppy disks are still alive or dead after all this time.
