Here's a PCB I've made from the original design in the Beebug Magazine (August/September 1985).

Acorn System 3 / 4 Floppy Drive Enclosure help

Hi All, I’m in the process of constructing a pair of Acorn System 3/4 drive enclosures to mount a pair of Tandon 5.25 full height drives into a System 4 Eurocard case. Unfortunately I can only find sketchy early acorn press photos to go from and none of the pictures online show any details of how th...

Yup - the connector is away from the PSU - you've had it in backwards I'm afraid :( It's highly possible you've toasted the CPLD in the beebscsi :(

Yep - that was a dumb user error - dead as a dodo :(
Luckily the BeebSCSI is ok.

BeebSCSI VFS Adapter issue

Hi all, I finally got around to testing the BeebSCSI VFS Adapter (internal Master interface card) for BeebSCSI today - I've had it for 2 years but never got time to try it out but lockdown's given me a bit of time. So to the issue; inserting the card causes the Master to continuously beep, with or w...

Re: System 2/3/5 Keyboard Progress

Hi Ade, I have @trev-ham's keyboard PCBs which output ASCII as required by the System 2/3/5 CPU Card. For the ASCII <-> USB conversion I designed a board -- basically I wanted to test my keyboard as soon as I built it. I'll put the files on GitHub and add a link here when done.

Great work Andy :D

I'm in the process of building Trev Ham's boards too (in NZ). Do you mind me asking where you got the keyboard interface cards you have used, or are they your own design?

Looks like it has been stored somewhere damp, looking at the cassette, RGB, composite video and Modulator connectors on the side.

Acorn Winchester Disc 110 - Drive replacement

Hi Guys, Does anyone know if an MFM Seagate ST 251-1 would be compatible with Acorn Winchester Disc 110 hardware? I've managed to obtain a working drive - before I start fumbling around thought I'd ask (unusual for me) - :D Drive is one of these... www.ataripc.net/wp-content/uploads/Seagate-ST251-Pr...
