I have a "repair rqd 71" error. My Unipak 2 is toast. Let's repair it!
Vintage computers (and Arcade Games), particularly the micro-programmed ones like the Xerox Alto we are currently restoring, use old but very fast bipolar PROMs to hold the microcode.
I need an old instrument to read them and to program them. Enter the Data I/O 29B with Unipak 2, fresh from ePay. It was the high-end EPROM and CPLD programmer of the time.
