Could I “advise” S100 people to lookout/get GAL programmers. I’m a total convert to these chips by now. All future boards I will do will probably use them. Including the future IDE-V3 and a 16MB static RAM board using 4 SMD chips. The slowly evolving 80486 S100 prototype board has 5 on board and even that is a tight board fit with over 1000 traces! The Wellon VP290 seems to work with most chips. However for reasons I don’t understand it requires the Erase, Program Verify & Secure options to be checked for LATTICE 22V10 programming. Also using a different manufacture designation for these LATTICE GALS will burn them out. See her for more details:- http://s100computers.com/My%20System%20Pages/ISA%20to%20S100%20Bus/Intro%20To%20GALs.htm John From: n8vem...@googlegroups.com [mailto:n8vem...@googlegroups.com] On Behalf Of Bob Bell I just bought a Wellon VP-290 to program GALs, since I am done trying to discover how to ask AutoElectric to add support for the Atmel 22V10 GALs on their Minipro TL866A. If I had a way to send it back for a refund, I would. I has successfully programmed any Lattice 22V10, but Atmel is easier to get. The Wellon has Atmel 22V10 in their support list. Interestingly, the Wellon VP-290 looks every bit like the Needham EMP-290. I read somewhere that Needham may have sold their programmers off to a Chinese company. Anyone know the details?
