This summer is going by at a scorching pace. I look around, and - oh, shoot! I haven't updated the SPOCS blog in over a month!
Part of that is because I have been working on an EEPROM programmer. It started out based on a design by a fellow named Mario. Like him, I based my programmer on an Arduino Uno. Unlike Mario, I used two parallel, 8 bit latch chips instead of shift registers. The programmer reads, writes, and erases 2864 and 28256 parallel EEPROMS. These are what I am using for ROMs on the new QL computer expansion board. It's USB-based, and you can use most any terminal program to operate it.
