EPROM/FLASH/EEPROM Programmer, MK-II
Final DVT/DEBUG IN PROGRESS, 4/19/2026
This is a rehash/revival of my original (circa 1990) EPROM programmer to allow access to the 27011 and 27513 EPROMS that ACC uses in their repeater controllers. The original goal was to read the EPROMS, and read/pgm 28C64 EEPROM and 28F101 FLASH devices.
The FFPGMR now supports EPROM read and program for several devices.
EPROMS: 27C513, 27C011, 27C64, 27C256 - 27C040
FLASH: 28F256, 28F512, 28F101, 28F010, 28F020, 29F040
EEPROM: 28C64
NVRAM: 11C68, 11C88
Smartwatch: DS1216E version
Autoselect mode supports all but EEPROMs/NVRAMs
EPROM algorithms fixed from when they got broken (who knew???)
Verify command fixed/re-worked -- addresses SRAM synch problems, now allows voltage margins on EPROM verify
Adding code to support limited GAL/PAL programming/de-programming activities. Autoselect mode used to identify GAL prog-adapter
Most features are complete. Other than GAL/PAL and EPROM algorithm completion, no activities are planned.
