Also, if you would be willing to share your scans, I would very much love to host them on this site. The higher the resolution, the better. . .

Yes, the boards probably won't be cheap to make. However, OSI boards often didn't have solder masks or silk screens, so a prototype quality run should be authentic. It should be possible, once you have gerbers and drill files, to import using a tool like Altium, and extract a netlist, and match that...

Wow, that looks really nice!

I'm interested in what methods and tools are you using to replicate the board.

Hi Paul,

Thanks so much for stopping by and posting! If you ever have the time, it would be great to hear more about your OSI experiences. That's the first I ever heard if anyone doing PCB layout on an OSI. I'd be extremely interested to learn more about what you did.

Mark Spankus has a copy of OS65D v3.3 bundled with his emulator. I also have a copy I can post, if needed. It should be possible to cut the image into 2K track-sized chunks, and use the srecord utility or Ed's OSILOADER utility to send load a track to the OSI memory over a serial link (see the LINK...

I welcome contributions, especially of software and scanned (or paper) manuals, stories, tips, tricks, hacks, and other info. working and non-working OSI hardware, either photos or the real thing. If you have some OSI stuff you'd like to share, but don't have the time or resources to scan documents ...

I have uploaded an 8" OS65D3.3 image file. OS65D338_1.65U This image has been constructed from the 5.25 image supplied with the winOSI emulator using Debug on the PC. Why ?... because I dont have any bootable media. I intend dumping this down to my OSI via RS232 and reconstructing an 8" bootable di...

Stephan,

Also, the srecord utility may be useful for converting a standard output format, or a binary file, to the OSI monitor load format.

Hi Stephan, That's awesome. Is the port primarily the creation of a library for the the C1P, or did you have to make changes to the compiler to avoid interference with page zero locations required by the ROM? Does CC65 use the hardware stack on page 1 for parameters and return addresses, or does it ...

Scott, that's an amazing find! Would you be willing to take some high-res pictures of the board? If you are willing, I'd love to include the board in the hardware section of the repository. It seemed as if the software for the board was at a very rudimentary stage. I'm curious if any operating syste...
