Very nice c64c cases, black is my favourite. Cheers!

Has it been tested with 8 and 16bit accelerators and RAM cards greater than 4MB?

That's been my experience with the Booti and the GS too - it's painfully slow...

How can a non DMA CFFA card perform better than a High Speed SCSI card which does DMA. A very slow disk drive?

Great video. Thank you for making it!

Until I saw the velcro strap I was going to take a guess and say Individual Computers. Low and behold at 2:15 in, there It is. :)

I would like to see results added for RamFAST SCSI interface with BlueSCSI & spinning HD, and also UltimateDrive

That is nuts!

One of the things I forgot to mention in the video; I was able to get the //gs on the network due to the kind work of a friend (and Corvus god) who burned a replacement ROM chip for the Apple II Corvus Transporter that allows the //gs to run at full speed. With out this modified ROM you have to slow the //gs down to normal (//e) speed or the transporter will not work. Unfortunately this same hack does not work for the //e with any kind of accelerator card (even if you set the card up to slow down for access to the slot the transporter is in).

The first Ethernet UTP version (the IEEE spec) ran at 1.5Mbit. The very first, Thicknet, over the RG8 cable was 5Mbit.

2:24 MC Escher would have loved that fault! What with the hum bar of missing bits looks like there's a hairline crack in one/some of the CHR ROM's address/chip select lines.

Awesome Commodore find. Working adding machine, nice :) Happy New Year!

Very cool project!! Do you know if the documentation is available on the GitHub page? I went there, but none of the documentation loads is found. Thanks for sharing

Cool video, I used this computer in the early 80’s , it was backed by the government and rolled out across UK schools as an educational tool.

This was a variant of the Kyocera KC-85, the design of which they (Kyocera) licensed to several other companies. -Olivetti had the M10 -NEC started with their PC-8201x models, eventually creating clamshell formfactor models (PC-8500 ultimately) -Tandy evolved the design to their clamshell formfactor Model 200. Their Model 600 was a very different beast. Been diving down this rabbit hole lately. Side note: Disk/Video Interface (D/V-I) is an external accessory that interfaces with a host unit via a system bus connection; this is either achieved through the ROM socket on the original model 100, or the system bus pin header connection on the model 102 and 200. It can house up to 2 FDDs as well as providing video output to a CRT.

My very first computer. I actually was able to order it as a kit that had to be assembled. I enjoyed it very much and used it to learn basic. I still have it along with a 16 kb expansion ram pack I ordered.

Cool video! Some comments / corrections (I am one of those "Coco Nuts" you mentioned at the beginning... lol). Coco 1's could go up to 64K of RAM (although Tandy didn't announce that the first couple of years - on launch there was just 4K and 16K RAM, and either Color BASIC by itself, or Extended Color BASIC (which add line editing, high res graphics, better sound commands, etc.). The 128K and 512K you mentioned would be the standard Coco 3 RAM sizes. (Of course, 3rd party addons could go beyond those, and did. Still do). Color / Extended BASIC (if you added disk drives, it go enhanced further with Disk Extended BASIC), and then the Coco 3 version (nicknamed Super Extended BASIC, but they just called it Extended BASIC 2.0 / 2.1 themselves) were built into the machine's ROM's. Well, except for disk - that extra ROM came with the disk controller. OS-9 is a completely different animal; it's a multi-users, pre-emptive multi-tasking OS that required 64K on a Coco 1/2 (this was know as "OS-9 Level 1", of which Tandy released 3 versions: 1.0.0, 1.0.1, 2.0.0), and then the much enhanced Level II which required a Coco 3 (and thus a minimum of 128K RAM, but it really shone with 512K (or higher). These were full operating systems sold on disk. Level II, aside from allowing bigger programs, also had a windowing system built in to run virtual terminals, and excelled at multi-tasking for an 8 bit machine. (I am one of the authors of the descendent of OS9 Level II, called NitrOS-9 Level II, and you can see what that looks like in the screenshots on my free download page for it: lcurtisboyle.com/nitros9/nitros9.html). You are right on the CPU; it was arguably the most powerful 8 bit CPU at the time. The video chip was unfortunately an older Motorola chip from 1978, so it isn't as competitive with some of the other 8 bit machines at the time. (The Coco 3 had a brand new custom chip called the GIME, which made up for this with RGB Analog support, much higher resolutions and many other enhancements). As far as sound, it doesn't even have sound chip. However, it did have a PIA chip that could generate 6 bit analog audio out, which put it above some other machines that only had 1 bit "click" speakers (the PET, Apple II, MC-10 and some others) and could generate full digitized sound... but the CPU had to drive it itself, unlike machines with dedicated sound chips (like the Atari 8 bits, the C64, etc.). There were addons to improve this (even from Radio Shack), but because one had to buy a multi-slot extender (called the Multipack; it plugged into the cartridge slot and gave one 4 slots that could be used for ROM's and/or additional hardware) to use it with a disk drive, it was more expensive than most people were willing to pay. I would be interested in who your local Coco guy is; if he is active in the wider community I may know him. We still have a CocoFest in the Chicago area every year (in 2025 it is at the beginning of May); these have been going on since 1983. If you want to catch up on the Coco community, we have a weekly show here on KZbin called The Coco Nation Show, every Saturday at 2 pm Eastern.

Fully expanded, it was like a portable "MINI computer" (fridgerator size computers) of the time. 64 Kb memory and price up to $113.000 in today value... Also a computer "star" in Japanese anime (see "John Titor").

I tried that in a shopping mall, felt so incredibly "sluggish", finally chose a Commodore 64. My school mate at high school had the TI-99/4A, told me "But it's a real 16 bit!". I said, "In that case, something is terrible 'wrong' with it..."

I got one of these when TI began blowing them out. Paid $50 for it at K-Mart, brand-new. It was my first computer.

KWH - yes as time went on we got better and better computers to make better commercials with - ATARI 800 bring back warm memories - I want an 800 to tinker with. Thanks for the video

When I started in computers End of does 5.0 and 386sx machines. Did tons of Does 6.22 machines sporting windows 3.1 Sold new 286 boards and 386 boards. Got really good at config.sys and autoexec.bat files. Plus setting up non plug n play around cards. Use to know all the addresses. Sound blaster was what like 220 irq 5. sometimes 3. Anyway have fun.

Cool - I love this stuff! - can you tell me anything about how you were able to get e-waste

This screw in shield that is screwed to video chip heatsink is original.

Totally subscribed to this. I have 3 c128 flats sitting in a pile like yours and all are Black screening. With c128's, The most notorius chips to go are the Kernel Rom chip....and the MMU chip... both Blackscreen... With the Kernel Roms being the most notorious to blow...just like the C64's PLA chip.. ;) - Tony K. - Commodore Collector/Restorer.

I feel for you! I just tested all the 128s from the Stone collection this weekend. What a mess!

Yes. My school had this in 2nd grade. This would have been around 1990 I think. That login screen definitely looks familiar. Very cool to see.

Thank you for sharing this video! -Thom from FujiNet.

Are you loading the Disk II image (i.e. emulating Disk II drive/s) while your Yellowstone card is in SmartPort mode?

Another cool feature is loading from SMB or FTP shares - you can load images straight from the Asimov archive, for example, and boot straight to the FujiNet!

Great video, thanks for sharing it!

Now that is a very clever device 👍

very nice. loved WordStar in it's day.

Old time tech! It's like tinkering with an old '57 Chevy. Glad I found this!

I have no idea whatyou said but I was here to support brother.

Howdy doody, you go doodad

Very handy cards, make for a nice Apple II gaming setup 👍

Did you buy or build that HD emulator?

You're welcome, thanks for the mention! Nice finds but that hybrid PSU is terrifying!!! My SX 64 is waiting on parts for the final video. I am 99% sure that the sound chip on the CRT board is fried!

Your power supply says "smoked" LOL

I love building these kits. Have built a few clocks, a digital multi-meter, a couple Bluetooth speakers, etc. I have an analog multi-meter kit on my shelf waiting for a rainy day.

Like that z80 card, I has a 8080 out of an old winchester years back as a teenager, don't know where it went, wasn't ceramic though.

Wow. Corvus gear. I used to work for the Australian distributor and provided tech support and services the gear too. What a blast from the past.

Your Giving me High School Flash Backs....

we had a 20MB Corvus serving 20 //e's. it was a good system.

I will have to keep an eye out for this!

I have never seen a Corvus OmniNet before, this is pretty sweet little system.

Update: I mentioned in the video that the Booti uses SmartPort to emulate up to 8 ProDOS hard drives. The Booti does also support Block mode.

Very interesting with all that stuff :-) Should you find a keyboard for a Commodore 8032-SK, and have no use of it, please let me know. :-)

Very cool...I have an SX-64 that had been working...When I powereed it up last it had not video but that is a project for a nother day for me. Good luck with yours I will be watching.
