EschatologicalEngineer developed a useful test jig for use in ROM analysis. “Greetings, I thought I would share a picture of my ROM Dumper rig. I used a Teensy 2++, ribbon cables and a “Glomper Clip”. I first learned of these clips from the brilliant works of Don Lancaster. I was able to purchase the clip from Electronics Surplus Inc. for about $5, (SPC Technology, 28 Contact, IC Test Clip, Type No. SPC21094). It works perfectly along with male-to-female cables to handle the large amount of data and address pins of a ROM.
My target ROMs are AM27C128 from boards made in the 1980’s that feature MC68B09P processors.
I hope that by sharing this information, others interested in building a ROM dumper or interfacing with similar DIP ICs will see how tidy and helpful the combination of a test clip, M-F cables and a Teensy2++ can be.”
