Working on an Acorn RISC PC600 which had battery damage.
Looking like this without VRAM module ... so the error must be around the onboard VRAM or it's logic.
Any hints where to start?

So my RiscPC has packed up again. Not anything major this time thankfully, but for whatever reason my boot SD has corrupted and now the built-in IDE isn't seeing any SD or CF card. I think the best course of action is to get one of those new ZIDEFS podules as that is verified to work with those CF adapters... But that's gonna be part of a larger re-rebuild I want to do - so expect a "Part 2" to that video I did eventually!

For now, the Acorn is gonna sit in a sad state waiting for me to afford to fix it...

Today's project. Get #NetBSD installed on the #RiscPC on some form of storage. Requires a different Ethernet module as the i-cubed EtherH is not supported #retrocomputing

Fixed the RISC PC power supply. Needed a new Schottky diode, and I replaced the optoisolator for good measure. Booted up fine after a CMOS reset. #acorn #retrocomputing #riscpc

Any #Acorn #RiscPC users remember The Clan? #retrocomputing

A new #ESP32 project: I want to build an #USB to #PS/2 adapter in order to include my old #Acorn #RISCPC into my KVM switch setup.

I am struggling with the USB implementation of the ESP32. It seems to have problems with hubs and devices that send 16bit values.

Anyone knows what this lonely litte transformer is supposed to do? Found it in the #PSU of the #Acorn #RiscPC. It's connected in parallel to mains, but has no wires coming out of it, so it can't really do anything apart from getting energized. What's the point?

This poor little #Acorn #RiscPC arrived today thanks to @mhd

Will be a heck of a lot of effort to get it repaired and looking good again, but should be doable.

Since I upgraded to Samba 4.20 on my #NetBSD fileserver, my #RISCOS #RiscPC was no longer able to open files for writing. Did a quick search and found that #LanMan98 was open-sourced in 2021 and I'm pleased to say the latest version works brilliantly. #retrocomputing

Cleaning up for new year, I've got this #Acorn #RiscPC that has sustained some leaked battery damage and might have other issues I can't test right now. Otherwise it seems pretty decent, so I wonder if someone in the #retrocomputing crowd would be interested.

I'd like to see it end up in good hands and maybe being brought back to life. Shipping & handling only, preferably in Germany or Europe.

A while ago I felt inspired watching an old 90s Acorn promotional video and wanted to try to do a newsletter/magazine article myself... And I wanted an excuse to try out Ovation Pro anyways.

It was one of those things I gatekept myself from doing on RPCEmu as I wanted to do it on real hardware... Now I have gotten on my Acorn up and running - I could finally allow myself to use Ovation Pro, and what better subject to base this article on then the Acorn itself? /rh
I'm not going to say it's perfect or professional (because it's not); but I'm happy enough on how it came out after 2ish hours of work (might even export it as PDF someday), and even more so that I figured out the DTP program without touch it's manual... I had fun doing it and that's the important thing! /gen /srs
