The chips have arrived... I have a display... It says LYNX and has a flashing cursor...

I had a while of it not working and a contended data bus. That was due to the BOM saying that there should be a 74LS273 in one socket and the schematic saying that it should be a 74LS373.

When I type PRINT it crashes.

I need to retest all the RAM just in case.

Hehe... Yeah.

Well, I'm back to the same RAM refresh issue I had on the 128K. It's not reliable enough for the first bank to reliably hold its data. I may have to look into the same sort of fix I did on the 128K.
