Hi Guys, sorry to change the long running topic of Fluke 9010A projects, but I thought that somebody might have an answer. I need to program 4mb 16-bit EPROMs. I have a Data I/O Unisite, but I can't get it out of Self Test. Data I/O was no help. I also have Data I/O 29B with 2B and a ton of other adapters, but I think that I would need an updates BIOS to run larger than 27c512, right? Any hacks available for those? I knew one company selling upgrades, but it was a small fortune. I also have a PB-10 with 210 adapter, but the 210 doesn't work. Needham's was no help and concluded that my programmer was bad. So, I bought another PB-10 and new cable. Both work with 8-bit, but neither with 16-bit with 210 adapter. I have seen a few companies selling generic 8-bot to 16-bit adapters for around $95, but is there any plans to build your own. thanks Dave
