Re: Today I received.....

Cheap and useless DOMs : they are 8 Mbytes and I misread I thought they were gigabytes ... Use the voucher if you wish. What's the interface on those? Are they drop-in replacements for disk drives on some kind of PC expansion slot, or something else? Looks like 44pin IDE - same as a 2.5inch HD? 8mb...

If it's not that, or the interesting looking memory upgrade, then the IOC says "Albion" on it (VL2311-QC), which I think means it's an early 'Issue A' machine?

Excellent - be interested to see how you get on. I have the skills to follow instructions, but sadly not the knowledge to work these things out for myself from scratch, so I'm hoping that the various guides out there will see me right.

Other than putting some conductive paint (the kind used for repairing PCB traces) on the keyboard pins (if that's even possible), I think the closest you'd find is something like this: https://www.amazon.co.uk/gp/product/B00MG9X3VG/ref=s9u_simh_gw_i1?ie=UTF8&fpl=fresh&pd_rd_i=B00MG9X3VG&pd_rd_r=9WZW...

Re: Vectorlight's A3010 IDE mod : step by step guide

@Andy1979 : I've got one of these memory upgrades, and in fact it's a 3 Mbytes RAM upgrade (it's even written on it). It means if you wanted to install some 50 ns RAM chips, you'd have also to replace the onboard 1 Mbyte. (if you're interested by the other fast A3010 project). It's OT in this threa...

Re: Is the Retro Bubble going a bit flat?

I guess we are lucky that due to the success of ARM we can run RISC OS natively on new hardware - and very cheaply in the case of the Raspberry Pi - rather than needing to rely on relatively expensive upgrades to older machines. I'm quite shocked at the value of my Acorn / BBC machines. I nearly sol...

Re: ArcEm running too fast on RiscOS on Raspberry Pi

You could try a different emulator.

I have been impressed by !ArchiEmu which allows you to choose the CPU (ARM2,3,250) and turn various CPU features on and off. I am only using an original Pi1 256mb though, so no idea how fast it would run on a Pi3.

Re: A3010 With Serial Mouse

It worked well enough, although the serial mouse wasn't quite as smooth as the original. Does your A3010 have RiscOS 3.10 or 3.11? Mine ha...
