I have a Pocket Romulator-I (Eprom emulator) that I used for 7427 (256 chips and below). I used it a lot to program my 7427 and always worked well. I bought a pocket romulator-II when I moved from the 7427 to the 16196395 (512 chip) and it would no longer serve my purpose (have not used in about 3 years).

It has some dirt and scraps, but works and comes with a serial cable. Software is available on website/internet.

I paid $179 plus shipping but will take $99 plus $10 shipping anywhere in lower US. Paypal only.
