Meanwhile, Positron 9000 probing carries on apace with the Fluke 9010A. I can read the boot vector at $FFFE/$FFFF and random ROM locations so the data/address buses are working. It won’t run though, so the monster Agilent is hooked up to the CPU to see what’s being read.

I'm intrigued - what's the extra cart doing? I saw someone doing a Teletext adapter for the P2000T, is that you?

Ah no that's Ivo Filot; but he did design the 'slot2 breakout board' that I'm using here. Since the Z80 address/data bus (and more) is on there it's an easy way to diagnose issues or even breadboard a cart. I've been working on an ethernet adapter for the P2000T (and perhaps also B aka P2500).

Ah I should’ve guessed it would be Ivo. Been chatting to him about the possibility of using a P2000T to archive STC Executel tapes but it doesn’t look like it’s currently possible because the archiver is expecting the tapes to be in P2000 format.
