Unimplemented Trap

The tweets of Simon Boak: electronics, hardware, software, vintage computing. A gentle non-conformist.

I made an LCD monitor which doesn't look out of place on top of an Apple II

I also tried a 📂 notebook https://t.co/JJ7ag7hvIY

Minimalist UI experimenting

Time to solder it up and see what works

[Unimplemented Trap @unimplmntd_trap]

Debugging is in progress. Nothing solved yet…

[Unimplemented Trap @unimplmntd_trap]

It’s time to sniff some busses

[Unimplemented Trap @unimplmntd_trap]

Testing some 2D CAD snap points

[Unimplemented Trap @unimplmntd_trap]

Believe it or not, but this is actually progress

[Unimplemented Trap @unimplmntd_trap]

@callumbwhyte Oh snap!

What’s your favourite iMac bottom? Mine has to be the G4

Finally found a project for this old prototyping board

[Unimplemented Trap @unimplmntd_trap]

@matseng I got very lucky on eBay a couple years ago: only bidder got me a box of them for only £20. Total value new would have been £300+

I want to see how many bits of wire wrap insulation I’ll have stripped when I finish this board

[Unimplemented Trap @unimplmntd_trap]

My first wire wrap 6502 SBC from 2016. It had some design limitations (and reliability quirks) so I didn’t take it any further. Its components will live on in my new project

[Unimplemented Trap @unimplmntd_trap]

I’ve now published the model for this https://t.co/zxPKwNOaCw

Shining up the G4

Just punching some holes
