Re: PC Memory Timing Strangeness

The IMC question was speculative on my part - if the cpu has a slightly weak/elderly integrated memory controller it may be okay for two sticks but unstable with four. Checking the forums out, this can indeed be an issue, more so if the ram is being overclocked, but also at stock. What is your cpu? ...

Re: PC Memory Timing Strangeness

Try 24hrs Prime95 on Blend? Since you don’t know which (if any) component is flakey, Blend will test all of them. If it throws up errors, the culprit FFT size will help track down if it’s memory/cpu etc... Then try individual sticks if it looks like memory. How long did you run memtest for (and I pr...

Not archived them yet. Probably should before bit-rot sets in. From what I remember, Z80 disc format is really just a big CPM file on a 80T DS floppy, so should just be a matter of copying under DFS to a dsd image on a Gotek?

Re: Help, I've just killed my Atom

It's all back together (something of a marathon), and it all seems to be functioning okay.

Sadly, one of my Pi zeroes seems to have lost its GPIO inputs, so it's completely useless for any of my expansions. That's something of a luxury worry though!

Crisis (hopefully) averted. It looks like it’s a problem with the “nut behind the keyboard”.

Re: All the cheese wedges, in order

There's an article in Beebug Vol 1, Iss 6 (Oct 82) about the Tube. This refers to the 6502, Z80, and a "16 bit NS 16032 based machine", which goes along with what Acorn claimed they would be producing. It would seem there was a common perception that the 16032 was 16-bit, which was why NS renamed it...
