You lucky devil! A Dataman S3 (aka "Softy 3")? I saw an S4 for ?165 at a
hamfest. Had there been a bank machine within 10 miles I would have bought
But there is some consolation. I'm getting an Elnec PrEPROM-02aLV EPROM
programmer for Christmas, so all is not lost. I'll take a few known-good SGS
27512s out of my parts box and test the programmer with them, then test the
Ace ROMs and check them against Paul Robson's ROM dump (the Paul Robson who
wrote a Jupiter Ace emulator -- the emu was called Ace32 iirc).

That would be great - have you got a copy of the TI TMS2532 datasheet, too?
I need to know if the two chips are pin- and read-compatible. Programming
algorithm compatibility is not required (the PrEPROM lists the TMS and HN46
devices on the support list).
