This same guy had a 27C256 version, but erasable 27C256 lcc are really hard to find. You can buy OTP parts new, but not erasable. So he made a 28C256 version. You can still buy new 28C256 plcc. Maintaining a socket of some form is more important than I realised at first because I wasn't aware that eproms and eeproms might lose bits in as little as 10 years. So an eprom/eeprom absolutely will need to be re-flashed again sometime. I found these low profile round pin headers to use with it. You need both qualities, round pins and close spacing between the motherboard and the module. http://www.king-cart.com/phoenixent/product_name=HWS5231 Untested yet. I'm ordering now. -- bkw
