RE: [oc] EEPROM Programmers using FPGAs? now its EPROM vsFLASHtime
Welll, I work for a big US based automotive company, so scrounging things from suppliers usually isn;t a problem. When we did have to buy flash chips, we have to buy a tray of them... sorry!

Martin,
are you in the UK? I'm having trouble finding a place to supply me with FLASH chips
specifically the Am29PL160C-70 units, want at least 4 probably more.
Thanks
Paul
