Finished the junkbox 2313 prog and Cemu board. I found an old card slot board that was only missing the clk pad so drew it on with conductive pen. It aint pretty but its there. The chips from left to right are 7805 5 v reg, 3.68Mhz osc, Atmel 2313, Lm7404 hex inverter, max232. Thats the programmer section. The Cemu consists of a Max232 and Atmel 2313, power, send and receive leds. It gets power from the ird card socket. I cut off the male ends of 2 db9 cables to connect the prog and Cemu to the pc.
The whole thing is built on a solderless breadboard so that the 2313 is flashed on one part of the board and moved to another part to run as Cemu interface. Making pcbs isnt fun.
