Re: Questions about my new purchase - Archimedes A3010

If you want to use ADFFS with the games released in JFD format from the JASPP software project you'll really need 4MB to use it comfortably.

Re: 20Mb Kalok Harddisc from A420/1 - not spinning

Also, the lube in the bearings of these can just gum up a bit with age. A drop of light mineral oil on the spindle bearing, turn it upside down so it enters by capillary action, leave it for 30 mins, wipe up any excess... That sometimes gets things going again!

Re: Prince of Persia

I have to say, for me, one of the glories of this is how it runs beautifully and looks gorgeous on stock hardware. Going the NULA route feels like it would have taken some of that away.

It uses too much memory IIRC. ADFS won't have the space it needs.

Re: Today I overclocked my A3010

It seems to buy a stock 4MB plugin, costs around the £80 mark. Is it cheaper to buy an overclocked version? So, yes, it will cost approx £80 for one from CJE, but that will be no different from the one in the machine if it has already been upgraded to 4mb. The memory upgrades aren't "overclocked" a...

Re: Today I overclocked my A3010

I would try overclocking it with the 4mb board you have in there already if that's what your intention is. You'll easily get 16MHz which is twice the speed of the original arcs, which is what all the games were designed to work on.

The beebscsi is probably cheaper (the pcb is smaller and less components) *but* look at dp11s pi zero beebscsi solution. That is much cheaper.

12V is on the main board as it goes through to the podule bus. Again, nothing uses it.

BeebSCSI or Dominic's pi zero based implementation are a better option for HDD (no need for patched ADFS). Couple those with the gotek/FlashFloppy and you're laughing.

Re: A5000 Power Supply Circuit Diagram

If you check the schematic, -5V isn't used for anything, it's just passed out to the podule bus. Your problem lies elsewhere it'd seem... :/

Re: RiscOS 5.22 on RiscPCs and A7000 series

It runs on the raspberry pi and other more recent platforms - there is software that runs on it, but why run it on a riscpc when you could run it on a pi which is 1) much faster and 2) more compatible with the OS? :)
