We also have gerbers for the 582 4-slot backplane, which my be of interest to anyone who would prefer a C4P style computer rather than a C8P big-box style. You can see the list of available reproduction boards on the Github site . Feel free to express interest in any other of the boards here as well...

To get this started, I'm in for:
1 x 502
1 x 505
1 x 540B
1 x 580
1 x 582

Now that we have Gerbers from scans of several original OSI boards, we are able to produce some bare PCBs. We already have some actual PCBs out there, including Grant's 600 and 610 boards, Grant's data separator board, Grant's 470Z disk interface with data separator and RAM/ROM, plus Jonathan's univ...

Dave,

I scanned and uploaded "The Bookkeeper's Bookkeeper" brochure to your dropbox folder.

Steve

Thanks!

Dave, I just scanned and uploaded "TinyCompiler1.3.pdf" to your drop box. Not sure if it's the same version you mention you're looking for. Steve Steve, that's awesome! I think that's the latest published version. Peek(65) volume 8 no. 3 lists a modified v1.1 to run on OS65D and support disk operat...

I have this board. I'm pretty sure it's a Mittendorf board. Unfortunately I do not have the instructions for it. http://www.6502.org/users/sjgray/computer/osi-c4p/TOSIE-hacker-back.jpg Steve Steve, It's been a while but I always enjoy browsing your 6502.org pages. Great stuff there--some really nic...

Yes, that's the Mittendorf board. Thanks for the nice photos. If someone were to trace out the schematic, I could write something up about it, since I did a hi-res mod for my C2 that I think would be similar enough. I imagine this circuit borrows signals from the video timing chain to sequence addre...

Grant, I see that the image links in your original post have expired. Do you think you could upload the images as attachments, so we can have them permanently available here? They are so gorgeous, I'd hate for anyone to miss out!

If Grant(Klyball) doesn't have any left, then I still do. Also, Grant has shared his Gerber files for the 610 and 600 boards. They can be downloaded from the archive, or from Github.

Klyball's 600D and 610 boards are now up on github. I've added links to the hardware section of the archive.
