Schematic Question

[Mike Katz]

I have two different revisions of the PiDP-8/i PC Board and i am trying
to find the schematics for both.

One dated 16-Feb-2016 Rev 2.2 and one dated 13-May-2019 Rev 3b.  I'm
trying to find the schematic for them.  I tried looking through the
repository at tangentsoft.com but I was unable to download just the
individual schematics.

I have found the following schematics:

            19-Jan-2015 (No revision #)
            11-May-2015 (No revision #)

I could probably do it with fossil and pulling the appropriate trunks if
I could figure out the correct trunks.  Does anyone have copies of the
schematics for my two boards?

Thank you.

Mike,

They wouldn't be on the TangentSoft site, that's all about the software. I know I've seen links on Oscar's site:

https://obsolescence.dev/pdp8.html

Poke around there, they should be available.

Mike,

The newer obsolescence.dev site has a schematic image but not the KiCad files.  The original Obsolescence website is supposed to have the complete set of KiCad files but the zip file only contains the Gerber files.

https://obsolescence.wixsite.com/obsolescence/pidp-8

I found a PDF file of the schematic in the forum and attached it to this email.  I might have downloaded the full older KiCad archive, but I have to check tomorrow.

The only available version of the design files I can find is dated 2015.  Supposedly the schematic is the same but the PCB varies over time due to different switches and small LED placement variations.  Unfortunately I'm having trouble corroborating that assessment.

The transition from the old website to the new one still seems to be a work in progress.  Unfortunately there seems to be a loss of some information.  I think further investigation may require Oscar's assistance.

The Kicad project files sloshed about on various places in the Google Group and website. But now, everything is put here:

See the bottom of the page for the download links.

Kind regards,
