Buying a Tech 1

[Malcolm Robb, LC 0112G]

Nope - I just need the cartridges. Any (non FLASH) cartridge will do. We already have the binary images to put in new EPROMS, and we are willing to share them, although I doubt they'll have any US applications. 

I have identified 3 different cartrige styles.

1) 1987-1990 contain a SN74HC373 and a 32K*8 (27256) eprom.
2) 1990-1994 contain a surface mounted gate array and a 128K*8 eprom
3) 1994-present contain a different surface mount gate array, and 3 surface mount FLASH Eproms

I can use (re-use!) any type 1 or type 2 cartridge. If you want to 'pull' the existing eproms, that's fine by me. I have traced the circuits of all 3 cartridges (which I can also share), and could make up new PCB's for types 1 & 2 if I had to. But the cases would be impossible for me to replicate. So it would be much easier if I could just buy half a dozen Type 1 or 2 cartridges from someone/somewhere, and drop in new EPROMS

Can you help ?
Cheers,

  Are there any particular cartridges you need? Some are for trans, body or 
  engine.
