UNITEK EPRAM -- EPROM Programmer

I probably purchased this EPROM programmer when I started developing my ST-2900 computer system, so I could program EPROMs containing different versions of my ST-MON monitor program for testing. Later I used it to program several hundred EPROMs containing ST-MON for shipment to customers. Unique Technologies advertised this EPROM programmer in '68' Micro Journal for several years.

UNITEK EPRAM features:

• 28-pin ZIF socket for EPROM being programmed or read
• 16-pin socket for personality modules (which I replaced with a ZIF socket)
• programs 2508, 2758, 2516, 2716, 2532, 2732, 2732A, 2564, 2764, 2528, 27128
• instructions provided for building new personality modules
• two LEDs to indicate when low voltage and high voltage supplies are on
• software was provided for 6800 and 6809 versions of SSB DOS and TSC FLEX
• component ID's marked, but no soldermask
• gold-plated SS-30 bus connector
• cost U$125 assembled and tested
