RiscPC PC Card

I've just acquired a PC card and am amazed at how well it works and how nicely it integrates with the RiscPC. I realise the computer was designed with PC support in mind, but nonetheless, I'm really impressed. So much so, that I thought I start a PC Card thread. There doesn't already seem to be one ...

Re: Electron key colours

When the wobbly electron arrived from eBay it was missing one of its feet. I bought a replacement from eBay ( not from Retroclinic ) and everything seemed fine. It wasn’t until I inserted the ap5 that I noticed the wobble. The feet on the electron and the ap1 are all worn to a different extent. I’m ...

Electron key colours

I brought my just-in-case electron down from the attic today and put it beside my main electron to compare the feet of the two machines. My main electron wobbles a little when the AP5 is inserted so I wanted to see if the just-in-case electron wobbled as well, which it didn't. The two electrons have...

Re: Running Wonderland from a hard disk

Here's the script I'm working on, which scans for all available filing systems. I did try to apply the patch locally to my win binary but I couldn't get it to work. When starting Wonderland I now see an error "No System Resources". I guess I've just updated the file incorrectly or perhaps I've misi...

Re: Running Wonderland from a hard disk

I made the modifications to the win file and the game now starts up fine and is playable. But I'm unable to get the save dialog to open, even though I also made the modifications to 28CB0. Actually, I wasn't really sure what to change this to. I tried setting the entire 32bit word to 0. Then I tried...

Re: Running Wonderland from a hard disk

And the RAM disk trick works fine. The game plays really well under ADFFS. I just need to remember to copy the saved file from the RAM disk before turning off the computer. Thanks again.

Re: Running Wonderland from a hard disk

Thanks for your reply. I tried naively replacing the harcoded SCSIFS::4 and ADFS::4 strings in the win1 binary with IDEFS::4, taking care not to modify the size of the file. The game still crashes in the same way. I guess it's crashing before it reads these strings, perhaps due to the first issue yo...

Running Wonderland from a hard disk

Hi All, I'm trying to get Magnetic Scroll's Wonderland to run from harddisk (IDEFS CF card) on my 4MB ARM2 RISCOS 3.11 A3000. The game runs fine from the floppies but the disk swapping is really tedious. The game comes with an installation program which seems to correctly copy all the files from the...

Re: BBC B / Datacentre Fault

I did have an issue with my BBC master's internal datacentre a while back. I don't remember the exact details but I do remember that *IMPORT didn't work and some commands seemed to hang. Running *RAMTEST followed by CTRL-BRK fixed the issue for me and it has not re-occurred.

Re: Acorn 3000 4mb Ram Expansion

I presume you have checked all the pin connections for the RAM connector including the solder joints? Actually, I haven't. However, I do have an existing 1MB expansion board fitted that works fine, i.e., the A3000 boots and reports 2MBs. So I guess that means that the main board is okay, unless of ...

Re: Acorn 3000 4mb Ram Expansion

I checked the jumpers in my A3000. The only difference I can see between our two jumper configurations is LK25, which according to the service manaual is used to configure the RGB Video Socket, so I guess this is unlikely to be the issue. If I read the manual correctly, your A3000 is configured as '...

Mark Hayesman (retroclinic) definitely has a stock of the through hole ones that you need for the A3000?
