What is this Data IO Thingie?

These are early programming adapters for the Data I/O Model 19 and earlier programmers. These were used before Data I/O developed the UniPak module which did all PROMs and EPROMs (except the 1702 ERPOM) There are two cards in the large Programming Pak, an analog card and a digital control card. (I forget the correct names.) The digital card had a prom based state machine to control the programing algorithm. The analog card generated the waveforms. This pak could be used in early Data I/O programmers that did not have a microprocessor. The you wanted to program a different part you need to swap cards. The smaller parts a pinout adapters. The two white things in the lower part of the picture look like your feet. http://home.earthlink.net/~pkaneko/data_io_stuff.jpg ------------------------------- Michael Holley swtpc6800(a)comcast.net www.swtpc.com -------------------------------
