Sanguino based PROM reader

PROM shield

This shield allows reading PROMs that were not supported by my DATA I/O 212 MULTI PROGRAMMER. The current version is limited to a 2716 and TBP28S86N compatible PROMs. Other devices will be added when I have the need to read them. For other devices like TTL-PROMs and PALs a different shield will be developed.

Wiring not on the schema:
ATMega644P TexTool function pin name pin PROM PB0 8 AD0 PB1 7 AD1 PB2 6 AD2 PB3 5 AD3 PB4 4 AD4 PB5 3 AD5 PB6 2 AD6 PB7 1 AD7 PA0 23 AD8 PA1 22 AD9 PC0 9 O0 PC1 10 O1 PC2 11 O2 PC3 13 O3 PC4 14 O4 PC5 15 O5 PC6 16 O6 PC7 17 O7

Usage:

Check and double check the wiring. Insert the PROM and connect the Sanguino to an USB port.
Start a terminal program with capture to file capability. I tried with the Arduino IDE Serial Monitor, but as there is no handshake implemented at all, it tends to loose characters. I use minicom (Linux) as it appears to have better capture capability.
Press the reset button to restart the dump. When it finishes, a checksum is printed. Keep this with the file.
