Fingers crossed the RAM will arrive by postie today and we can resolve the issue of the Z80 not booting correctly.

It's now 7 days since I ordered, but there is no tracking, so a lot of this is me just hoping...

I wish they'd always send things tracked.

Me too, the suspense of it is killing me, especially since the new stuff will let me do two things:
  1. Verify the TL866Pro as a good way to test static RAM.
  2. Hopefully fix the Z80-MBC2

All the possible OS options work just fine so it's a good result.

Sure it means I have a spare non-cmos Z80, but who doesn't need one of those? It was also £7 for single IC and about £11 for 4, so I have spare RAM now too :)
