... we are getting there. 2x 2114 (1 KB) on this 6502-based Lab-Volt trainer. 6502 RAM timing is quite a bit more delicate and aggressive I must say! Challenging to get this right, took me a while. Now, basic RAM emulation is working, but I currently cannot fire up the second core for the UI (and reading the UI button and such) without causing "glitches" in the matrix umm RAM emulation. Still need to figure something out there. But, overall - it works!
