I own an Acorn A3020 with a 386sx PC card. Sadly, the mouse does not work any longer, probably a blown fuse on the mainboard. Have to repair that some day.

I have two or three acorn mice, non of them are fully working 🙁
so I went for an PS/2 Adapter instead. This thing is working fine.

I am searching for the PC-Upgrade-card for my A4000 a long time.
All I could find are some later PC-Cards for the Risc-Machines.

It's not an issue with the mouse but with the machine itself. I have several Acorn mice which all work.

My A3000 just played up after trying to load a single mode Dos emulator. Hopefully I'll get it sorted though. Just playing with dosemu in a terminal on Turbo Linux 6.0

are you sure about that! I am pretty sure that they are broken inside, one direction does not work, all other things do work.
A PS/2 mouse on the Adaptor fully works.

Yes. Not a single mouse is working at all, the port is completely dead. It actually stopped working while I was using it.

Seems to be the same thing that I need for my A4000?

That's the same card, yes. Back when I bought mine, these were available in large quantities and cheap. I paid 30£ for the card in it's original box (well, the sleve was missing, but who cares) and with all the manuals. These days, it seems to be very hard to find.

30 Pounds? crazy...searching a long time, never saw one.

Well, that was in 2014. 😁

With the few Acorn systems I've had they can go wonky in odd ways. I have an A4000 whose hdd controller doesn't function, one with the famous keyboard not beong seen issue and one that only see two megs of ram when it has four megs fitted. Oh the joys of old rigs.

If you haven't checked the battery on the mainboard do it, they leak and I think on some models it eats the mouse port traces. And will only get worse.

No corrosion damage at all. Thanks for the input.

I've collected nearly the whole range of Acorn RiscPC x86 co-processor cards, along with it's software.

Over the years Acorn PC emulator software and hardware shipped with various versions of Dos like MSDos 3.3,DRDos 5/6, IBM Dos 6.3. Acorn RiscPC x86 co-processor cards came with a complete licensed Dos package, as seen by PC Dos 6.3 in the pic above.

Acorn x86 co-processor cards that can be fitted are 486SXL-40, 486DX4-100, IBM 5x86C and a couple more iirc. Some are socketed so you can have a go at experimenting with various other x86 cpus by swapping out oscillators. Acorn RiscPCs are kind of a geeks wet dream of a system really. I wanted one when they first came out but had to wait a few decades before I had one in my grubby hot little hands. having aquired one I endevered to see what ather Acorn Risc based systems were released. There's a lot more to Acorn Risc systems than most people realize.
