John / all - the JED files appear to be generated from OrCAD PAL, so my guess is that the schematic was also done in an old version of OrCAD (probably SDT). I honestly don't know if they would open in more modern versions, and even if they did, if they require any custom component libraries it may be a dead end. Even so, I didn't see a board layout file in there... I have a copy of the OrCAD suite from that era somewhere that may open the schematics (library issues not withstanding), but I couldn't say whether the floppies would still read or not (Kryoflux might be my friend there), and am not sure if it's a hardware keyed version or not (we had both keyed and unkeyed versions in college when I was an instructor - they used Rainbow parallel port keys IIRC). It would probably be easier to simply manually re-draw the PCB using the PNG files for reference. Any of the free layout tools should make that fairly straightforward to do - how much interest is there in a replica? ----- Original Message ----- From: "John Robertson" <jrr@flippers.com> To: "Technical Tools Mail List" <techtoolslist@flippers.com> Sent: Tuesday, March 26, 2019 10:54:57 PM Subject: [Techtoolslist] 3870 adapter pod for use with 6800 pod I can't believe it - I have had these files (Thanks to Shy!) since 2013 and only now realized I never put them up on TTL. This package from Shy (Navatek) has schematics (unknown format) pictures of the board layout and wiring, PALtoGAL 16V8 code and more... Look for it here if you want to make the adapter PCB: ftp://ttl.arcadetech.org/TTL/Test_Equipment/Fluke/9XXX%20Pods/3870_adapter_pod/ I'd buy a board if anyone ever figures it out...
