Schematic and flash utilities:

FLASH UTILITY for this interface support programming protocol for Am29F040B flash chip (or equivalent).
I test this chips:
AM29F040B (AMD) - 512kB flash eprom (internal structure 8x 64kB sector)
A29040B (AMIC) - 512kB flash eprom (internal structure 8x 64kB sector)
All work correct, no problem. But this flash utility is writed only for 512kB chips ???
I have also UT621024PC-70LL , AT29C010A-90PI (ATMEL).
My idea is add support for other FLASH EPROM/PEROM/EEPROM to one universal FLASH UTILITY.

For flashing is usable also my MB02 memory interface:
