Hey everyone not a big commodore person (no offense) but I have this prototype board from 8250 development looks like they were slimming it down for other computers in their lineup. I don’t know much about it or its history but if someone is interested in preserving it or buying it I’d love to...

Well max and I basically have it finalized I have a working unit and so does he. I recall he will be selling these when he gets to it (as we all know he does a lot especially reverse engineering). But design is pretty much final and good to go.

Beat me to it @max1zzz is 100% correct an early board.

Wow I didn't even know about this thank you @JustG for mentioning it and @dosdude1 for creating this neat little solution!

I think THIS is a great solution I've ordered one for my TAM. Plus at USD $15.00 it's quite a bargain.

Actually I agree with what you say but remember the drive is a smaller 2.5 style sized drive.

I'd say resistors are okay just need some cleaning. Is this a few trace breaks? Aside from that I'd say this could potentially be causing you some issues. I have linked the iie schematics HERE and they should help if not I suppose it could be a bad LS chip or something custom like a ROM, the...

This is neat Joe!

IIVI, IICI, IIVI, Performa 600, and Performa 650 are all basically the same PSU, thanks!

Absolutely 😃

I posted an update HERE with all the user guides, troubleshooting guides, and documentation I have.

This is a collection of documentation that came with the Apple TechStep. This includes the "Troubleshooting Guide" (volumes for CPU Tests 1-3). This also includes the warranty and ROM registration/Survey documentation. There is also the "Users Guide" for basic setup and SCSI troubleshooting...

I made the ROM's, awaiting a response back.

As most of us know the worlds supply of DB19's has sadly dwindled. This leaves many of us in the community in a tight spot when it comes to developing new creations and devices for our beloved machines. While there are DB19's out there they are limited and expensive, and that's not the sellers...

I agree very buggy. They do work on normal TechSteps though in case you want to try. Very neat findings! The TechStep is just such an interesting part of Apple’s history.

PM me and we will work it out.

I can make you a new one, I have the items to make you one so long as you cover cost of shipping and the 27C400's I will do it free of charge.

Super awesome I’m so happy to see this come true

Loving it and hoping to order these soon

Sooner than you think 😉
