45 days until #RetroFest 2026 in Swindon. #PERQ status:

• Flaky Z80-based I/O subsystem: sometimes the #Z80 jumps off the tracks and executes nonsense code
• Disk boots fail: the microcode attempts to load blocks far beyond the end of the disk

Trying today: DIY diagnostic microcode

I've just stumbled across the "unofficial retrofest ad" and I'm still chuckling at it now...

Hoping to be visiting again on the Sunday this year fingers crossed!

EDIT: I also feel pretty proud to be the only person on that list who has Mastodon as their primary social media account. 😁 I was wrong - there's more of us!

I'm going to try to replicate this on my Siena before #RetroFest this year. It's such a smart repair!

I'm booked in for #RetrofestSwindon 2026! Can't wait!

It's also another chance to visit the fantastic Museum of Computing.

I'll fly into Bristol and take the train. I'm looking forward to it!
