VIC-20 Super Expander and EPROM programmer

[@joelonsdale]

I had a Vic-20 back in the mid-80's when I was about 11. I once tried to code Trivial Pursuit in Basic and spent weeks trying to make the pies and wedges and a circular board. When I finally succeeded in getting something that almost worked I started the process of entering the questions by hand. I typed in one card before running out of memory and didn't have the knowledge to design a workaround. In disgust I sold the Vic 20 and bought a guitar. Thanks to the Vic 20 I have been a professional musician all my life 😅

[@jamesslick4790]

Wait? Doesn't EVERYONE?

[@RonMcMahonVideo]

In 1982 my first software company wrote games for the VIC-20. We wrote our games in Assembler because of its speed and compactness. The one key point that isn't clear in this video is that the memory location that held graphics changed when you added a memory expansion cartridge, and each different memory expansion option (there were 3K, 8K and 16K versions) changed the memory map in a different way. What this means is that you couldn't write one set of code that would support every expansion option. You would need to write a completely different version of your app for each unique memory configuration, which was quite impracticle. Had Commodore designed the VIC-20 with a static memory location for video RAM regardless of added RAM, I suspect that they would have sold a lot more memory cartridges and the non-cartridge games would have featured expanded versions for higher memory systems.

[@napomania]

So normal games can't see any exoansion ram on the system?

[@seancurtin6103]

The 3k expander didn't move anything though. Only the bigger ones did that. It mapped into the RAM gap between adr. 1024 and 4095, which further suggested that the machine was originally intended to have the Super Expander features on-board.

[@WinrichNaujoks]

Did you write the games for the VIC on the machine itself or was there a different computer to help you? Hand coding assembler and putting in each digit with help of the machine monitor seems awfully tedious...

[@JustWasted3HoursHere]

@@WinrichNaujoks If he was doing this in 1982 there weren't that many choices for development. I imagine they were using an expanded machine perhaps linked directly to a non-expanded one for quick turn-around during testing. Nowadays it would be so much easier to develop for those old 8 bit systems because of the multitude of tools (software and hardware) available.

[@fabian999ification]

I thought it was slow because it was in BASIC, but the circle functions where programmed in assembly!! This means that even in native machine code it is still not very fast. Although, the 6502 processor was only running at 1 MHz

Awesome. I had (still have) the VIC20 and the 3K expander. Became necessary as my coding got too large when I was a kid. Started my coding career right there in 1980 and still going strong today writing large system software for multinationals. The skills I learned back then are still valid today!

I had a Vic 20 as a kid around 1981, i loved that thing! I had a few games on cartridge but my favourite was an adventure game set in a nuclear power plant i think but cant remember the name. I had a graphic expander which you could make and animate graphics on as well as an I/O card, you could attach inputs and outputs that could be programmed from the Vic 20

That sounds nice. I think there were only a couple programs using it in the Compute!'s Gazettes I had. And since I got it when I was done programming on the VIC-20, but using ~56K on the Plus 4, it wasn't that helpful. Had I got it earlier, maybe it would have had enough RAM to run an assembly program?

Still, to this very day, the Vic-20 remains the single worst investment I've ever made in my entire life! I worked all summer cutting grass, cleaning garages, etc. to get the money to buy one. By the time I finally had enough money to get it home, not long (6 months later?) the C-64 came out. All of my friends had a total gaming monster, while I had a useless hunk of plastic, that could barely do anything. Yes, I'm still pissed off!!!

[@chrisk8208]

Larry, you should have learned to program it. I did. Many hours of fun. Computers aren't just gaming machines and the Vic 20 was a long way from being a "useless hunk of plastic, that could barely do anything" you were just a useless kid who could barely do anything. Onya for at least earning the money to buy it yourself.

[@LarryTalbot_1313]

Thank you for the insult, but not quite. I did learn to program it, even machine language later on with the C-64 (did you learn machine language?) But it was so limited that I could not program very much. It simply wasn't built for serious programming. (As serious as a person could get in those days, that is). The C-64 was pretty much a solution for all of that. I was able to program everything I ever dreamed of and a even dreamed up few utilities that weren't available either. I never regretted buying the C-64! Again, thanks for the insult. But once again the nourishing teats of wisdom have failed!

Excellent video, the VIC-20 is a very interesting older brother to the C64. I liked the AI video, I didn't agree exactly on what was being concluded and deduced but I would have loved to see a healthy intriguing discussion taking place instead of what happened. I think it is okay to disagree and communicate about it and be friendly, that's what I personally tried in the comment section of the video that was taken down. Sadly this constructive discussion didn't happen and I can understand why the video was taken down because of people being disrespectful. A lot of work goes into these videos and to see one go to waste saddens me. Anyways keep up your excellent work. You can't please them all but that's okay.

[@theolmaestro]

Great video! IIRC one could use the Super Expander as standard 3K expansion RAM with the VIC-20 if, and only if, the expander was plugged into a memory expansion board. That board allowed 1) multiple RAM expansion cards to be plugged into the VIC's expansion port, and 2) turning off selected memory blocks on each RAM expansion card. I think the Super Expander commands were in block 5, so if you turned off that memory, you'd get the full 6565 bytes or so, and programs that needed 3K expansion would run without problems (but you'd lose the graphic and sound commands). Ah, memory - uh, memories. Thanks for sharing!

[@sandal_thong]

I thought there was such a thing allowing multiple expansion cartridges, but never saw it. The 8K and 16K seemed so expensive, getting a board to hold both was out of the question.

[@kevinsammut7246]

[@racer9x]

That video brings back the memories. Vic-20 was my first computer. I had one of super expander cartridges, just like you explained. I remember playing the game hard hat climber which I typed in from the magazine compute's gazette. Didn't have a joystick so my Dad made one out of a can lid mounted on a bit of sponge stuck to a bit of wood, with 4 screws to act as contacts for up, down, left and right. And a doorbell switch as a fire button. It wasn't the most elegant joystick, but it worked well.

[@ChrisCebelenski]

Spot on about software support for these kinds of expander carts. I was doing commercial development for the C64 around 1984/85 and initially considered Simon's BASIC for the C64. But this would have limited the market for my software to essentially zero, so I needed to re-implement the routines that used the extended commands in my own ML routines. Plus there were distribution rights that my publisher didn't want to deal with, all of which added over a month of development time and necessitated investing in a BASIC compiler (Blitz!) for general speed improvements.

[@grayday8089]

This video takes me back to my childhood and being a young teen in the 80s. My father bought the vic20 and was using it from home for his work. He'd connect to compuserve over the 9600k baud modem and do email. The coolest add on we had was a voice synthesizer cartridge. Once plugged in, you could make the vic20 say all kinds of funny things.

Reminds me a lot of the graphics commands in the Plus/4 and C16's BASIC 3.5. We had precious little to lord over the C64 with its sprites and SID other than graphics, disk and structured programming commands (and windowing and scrolling with Escape codes... and 8 fabulous shades of black)

[@The8BitGuy]

yes! The BASIC 3.5 on the Plus/4 and C16 is my favorite version of Commodore BASIC. The BASIC 7.0 on the 128 was too slow and overcomplicated.

[@monolalia]

I thought it was basically the same, just with more of everything? Sprite commands and such... too bad if it was slower.

[@ncurtis1970]

[@sandal_thong]

I got the Plus/4 before getting the 3K expansion, so didn't use the latter much. Commodore really went into the ditch or dead-end with the Plus/4 and C-16, when their line of development was PET > VIC-20 > C-64 > C-128 > AMIGA.

[@BastetFurry]

Its the same as with Simons Basic for the Breadbin. It was made because BASIC V2 kinda sucks but no one used it for something they released. I think the first time i heard of a game demanding an upgrade was Dungeon Master for the Amiga, which balantly said "1 MByte or get lost!"... now imagine if game devs on the Commodore did the same and said "REU or get lost!", what games we could have. ;)

[@The8BitGuy]

Speaking of Simons' Basic.... guess what will be in an upcoming video? :-)

Nice :D Maybe you can show some newer hardware too, like the SD2IEC, an AVR-Based SD card interface that can be homebrewn, or the Chameleon, a 1541 emulation in a FPGA, throwing 16 MByte REU and a 6502 turbo into the mix while we are at it, or the Retro Replay, an Action Replay "remake" with a clockport with a RR-Net attached.

Also, any idea why the EPROM burner didn't just include the start ROM on-board? Seems unnecessary to have to load it separately every time. I feel like the odds of damaging that chip is high due to all the handling.

But that was enough apparently. Once I found the Introduction to BASIC Programming book that came with it (my parents bought the machine from some other guy they knew so I have no idea if those books came with every one) I was off to the races. I immediately fell in love with programming. I carried the books with me everywhere I went.

One factor leading to the low memory was the price of RAM in the early 80's. Dynamic RAM was pretty bad, static RAM was crazy expensive. The VIC-20 had static RAM (5Kbyte), so putting 18 or 6K in it would have increased the price too much (I'm guessing a bit there on the reasoning at Commodore). - I had one as a kid... did not like it that much. I really liked the C-64. - Eddy

i guess a vic-20 with 64k would have cost much more than a c-64

[@sandal_thong]

After reaching the limits of the VIC-20 without getting a memory expander, I wanted a C-64. There was a price war with TSR resulting in the prices going down. Instead my dad sent me a Plus-4, which I couldn't do anything with since the tape drive port wasn't compatible with the VIC-20.

The Vic-20 was a quirky system compared to its competitors. You mentioned the lack of RAM and the outdated BASIC, but you left out one of its most bizarre omissions. There's no hardware support for sprites. This made video games a bit of pain to program.

[@sandal_thong]

As he said, it looks like BASIC came straight from the PET, so maybe the lack of sprites was part of that, too.

I rarely leave comments, but felt like I had to in this particular case. yours is probably the channel I enjoy the most. don't let the bad comments get to you! keep up with the great work :)

I liked the AI video. It wasn't only about AI, it was philosophical too.

[@NJ2010100]

This is why I like this channel, it shows me stuff I did not know ever existed!

[@lackedpuppet9022]

I wonder what computers will look like when our current computers are out of date.

[@undeadelite]

LackedPuppet 902 probably like old computers

[@butwait]

Well Cave, you would know a thing or two about that, seeing as you left a trail of old to new behind through sheer science!

[@neerajdwivedi2015]

@joshbeech I think you should write 64 bit guy instead of 8 bit guy.

[@Firevine]

Oh man, those Ataris. I had those two as a kid. I miss them. I really dug the music for your game. Good stuff!

[@matthewbanta3240]

I keep wondering when you will do a video on ROM Rabbit or the expansion memory card with the dip switches added as a hack for the vic-20. Nothing like taking 20 minutes to load software that came from ... sources. You flip the dip switches a few times on the memory card, ignore a few system errors, and before you know it you are playing the version of choplifter that was only supposed to be on a cartridge (but was instead loaded from tape.) Also, when I was a kid I didn't know what sys7*4096 meant; but for the rest of my life I will remember it started ROM Rabbit. ROM rabbit was a faster version of basic. It shortened the commands so you could fit more code in memory.

Your game music sounds awesome. I can't wait to see it finished.

[@tjja7321]

Isn’t it spelled EEPROM? I don’t know, just asking.

[@tjja7321]

oh okay i didnt know that. eprom and eeprom are different? okay well i guess i know now! thanks.

[@Liam-sh3bp]

Eep! The ROMs are back!

Great video. It's nice to see tech that is no longer used today, being used again. Thanks.

[@pauljohnson7548]

Thanks for another great video. I hope you're not upset about the mixed reaction to your AI video. I think it's great that you tried something different.

[@stewiegriffin6503]

Don't take it too personal. As an act of spite , I would do the opposite and create additional channel "The AI Guy" with AI videos only. ;)

[@black_squall]

I think you've exceeded your comment limit for this video :P

[@stewiegriffin6503]

lol. I just like the AI guy, I mean the 8 bit guy.

[@the_eminent_Joshua_E_Hrouda]

That bit about putting the EPROM into the ZIF socket and then running the program by the SYS command was fascinating and quite clever. I wish there were more programs that would load like that!!
