Re: Acorn Art Thread

I been re-doing a cut-in/chamfered edge style Acorn logo, that I did in Xara some years back, in Affinity. Can't decide whether the nut should stick in or out...

Re: Scanned images of Risc PC motherboards

Tonight's scan: a 0197,000 mark 1 board. This has an IOMD20, rather than an IOMD21.

Flipping between this and the scan of the mark 3 board, I see that the small square RAS PAL that sits inbetween the SIMM banks vanishes on the mark 3. Perhaps integrated into IOMD21?

Re: I made a 3d printable replacement post to fix broken front flaps

I had a slice with a broken flap and a missing spring. When I did this fix I drilled through the case behind where the peg sits and bolted two M3 solder tags into place, one top and one bottom. This gave me a point in the same position as the original peg where I could loop the spring through. I've ...

Hi Dave. Nice designs. May I ask which company you used to make the mouse pads?
Of course. It was A1 Graphics of Annan, via this eBay listing: https://www.ebay.co.uk/itm/Personalised ... 4009033936

Re: Iyonix video card

It needs to be an Nvidia GeForce *PCI* card (not PCI Express or AGP). The Iyonix shipped with a GeForce 2 MX. I upgraded mine to an FX 5500 which helped solve the "pyjamas" issue (booting up with the card funted, it just showing stripes). I've actually been keeping an eye out for a spare lately and ...

I haven't tried 4.39 (which I think is Select?). The ROM sets I've seen on sale have gone for way more than what I'm willing to pay.
That's because they contain my highly-valued CDFSFiler v4.

Re: Help identify this Risc PC modification

Thanks, that does look like the (attempted) mod.

Unfortunately it turned out that the motherboard is gubbed and needs further diagnosis. I can get some sort of a video signal out of it, but it's not right at all. I'll be needing one of these new fangled POST boxes I reckon.

I double checked. The pin pitch is 2mm. Looks most like a PH connector to me.

Yep. Snaps attached. If you need more details, or the rear of the board let me know and I'll remove it from the case.

I've got a 100, 2x 200s, a 250 and a 260 here.
