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.
Can all registered uses please login, even just for a few minutes..
It helps build a picture where our "good traffic" is coming from..
Thanks :)

Intro retro computers since before they were retro...
ZX81->Spectrum->Memotech MTX->Sinclair QL->520STM->BBC Micro->TT030->PCs & Sun Workstations.
Added code to the MiNT kernel (still there the last time I checked) + put together MiNTOS.
Collection now with added Macs, Amigas, Suns and Acorns.

If it ain't broke, test it to Destruction.

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.
