Re: RiscPC virq/sirq issues

Hi Ian, There was very little crud visible at all, no visible green junk! The battery had a bit of fluff on it, which seemed to be mostly dust from the PSU. The symptoms were the same before a deeper clean. A pic from before the bath, but after I'd snipped the battery off. https://i.postimg.cc/pV1Xv...

RiscPC virq/sirq issues

Hi. Got a RPC 600 off fleabay. It's fitted with Arm610, 3.5 ROM's, FDD, HDD and Cumana CD-ROM. For testing I'm just connecting the floppy alone. I've tried with one stick or the other of RAM and with and without VRAM installed, symptons always the same. Battery area does not look bad at all after a ...

Re: Got an A310 + AKF11 - possible repairs and upgrades

The AKF11 power switch issue is *very* common on these CM8833 type monitors. You see a lot of them with paperclips holding in the power button!

Archimedes Keyboard

Interested in any Archimedes keyboard people may wish to sell - hoping to avoid CJE and Ebay prices!

I have a 310 and a 5000 and a half working 310 keyboard, so while it may be repairable I'd like another one in the mean time.

Thanks

For the keyboard; it still has has the function key holder: don’t try to remove it (to clean). The plastic is brittle, It will most likely break. For the keyboard keys, apart from the dirt the pads on the keyboard PCB can get tarnished. Some silver or copper polish cleans them up nicely. Be careful...

Re: Got an A310 + AKF11 - possible repairs and upgrades

Memroy upgrade on an A310 can be a fiddle, for sure. Backplane, RISC OS 3, ARM3 are all pretty trivial. You're spot-on there. A 4MB A400 would have been a better buy, honestly. Or an A5000, for its ARM3. These are easy to fix. Remove 3-gazillion screws, and you get access to the pads. I've cleaned ...

Hi all I picked up a completely stock A310 along with an AKF11 monitor this week. The AKF11 is fantastic, brilliant picture and sound. The power switch is being a bit reluctant to always work. Bit worried it's going to stick in the "off" position, so may leave it switched "on" fo...

No, when a best offer is accepted the price isn't shown in the completed listing except to the buyer and seller. I don't mind saying I offered £100 and it was accepted. The monitors working 100%, so even if the A310 is dead as described I'm not too bothered as it's a nice Akf11 with SCART and RGB. ...

Yes, that's no problem, just use *DISC for DFS and *ADFS for ADFS. You can even configure which one the machine boots up in as a default. Having a single drive is the best option for you I think. Do you still want a dual drive cable anyway though? This thread includes some photos of inside the mach...

The cable is non-standard and has to be made up by hand. However, I think I have a spare one which I'd be happy to send you. Similarly, if I have a spare EPROM I could make you a DFS rom. There are also other members on here who could do it. The pitfalls with the dual-drive setup are: 1) The fascia...
