Someone pieced this together BITD, pretty big. 2 Quote Link to comment Share on other sites More sharing options...

If you scan that bad boy, please do 600 dpi TIFFs and grayscale instead of bitmap- it's a lot easier to clean up on my end (and I'm fine with huge files- I can dm my ftp addy). I can compress the hell out of it later for distribution. That pic of the CPU in the schematic is exactly why I've been working on rebuilds- the current scans all suck for legibility. This FS015891 looks like it would cover only the earliest revisions- which is absolutely fine. I do not know what revision the C018040 version on Ebay covers up to. The Rev 2 FD100133 that everyone has a copy of covers to Rev 16+ VCS models, but I've never seen anything other than a mass-produced copy-of-a-copy. Would love to get my hands on an original, if such a thing exists. Quote Link to comment Share on other sites More sharing options...

I will look if I have a Rev 2 that is better than the scans, I think it may be original as well. Quote Link to comment Share on other sites More sharing options...
Kirkland Posted July 11 Share Posted July 11 I'm always interested in more legible schematics. Quote Link to comment Share on other sites More sharing options...

It's way past my sleepytime. They SHOULD hit mid cycle in reality. I'm at work and super busy outside of work. But I'll try to get you some actually useful information RSN.... BTW.... If you want to show the actual timing relationships, adding those colored vertical bars is a really good idea. If you want to show "ideal" timing, they would not be needed.
