It, too, is based on a magazine article — this time the article “Low-Cost EPROM Programmer” by Dan Vincent that appears in Popular Electronics, Feburary-March 1978.<\/p>\n\n\n\nThis programmer is entirely manual. Fortunately, 1702A EPROMS have only 256 bytes, and I only needed to program a couple of them.<\/p>\n\n\n\n
As with the 2708-2764 programmer, this programmer has a separate external power supply.<\/p>\n\n\n\n
I also built a little reader board that I could use to verify the EPROMs by connecting the address cable from the 1702A programmer’s console and +5V.<\/p>\n","protected":false},"excerpt":{"rendered":"
I have built two EPROM programmers over the years, in order to program 2708, 2716, 2732, 2764 and finally 1702 EPROMS. 2708\/2716\/2732\/2764 Programmer The first EPROM programmer I constructed was built in order to program 2708 and 2716 EPROMS for my Altair.
