< I had hoped to be able to use it to back up older ROMs which my circa 19 < EPROM programmer can't handle. Is it usable for this? It is the programmer of the era and with the right adaptors will program most anything including some faily current devices. The data io model 22 was faily close but newer and info on that will help with the serial port operation. < It has a serial type connector but no software (it predates the PC). The < is an LED and a hexadecimal keyboard. It looks like it was meant to be u < manually !! Typing stuff in character by character. The serial port acan be used that way but with the right terminal program and intel hex or Moto hex files you could up/download prom data. Allison
