I have four 8080 computer systems to dispose of. They were used in a dedicated industrial application - not as a readily reprogrammable system. Some of the chips may however be of use to someone - preferably someone who can collect from Chatswood, Sydney Australia. The main chips are (I am only listing chips in sockets) 4 off 8080A about 200 dynamic memory chips. some are marked 4030, others 4060. they are also referred to as 2107B-4 in the documentation. about 25 eproms type 1702A about 12 off 8212 i/o port chips about 30 off chips marked SN74S412. I cannot find this in my old data book but from the circuit they appear to be doing the same job as 8212 Also available are Intel data catalogues from 1976 and 1977 and a Signetics Bipolar and Mos memory databook dated 1977 David
