Re: RPCEmu 0.9.0 and Macs - beta testers wanted

I've just tried V3 of the patch on High Sierra and it seems to be working fine. I haven't done a whole lot of testing other than booting RO 3.71, launching a few of the pre-installed apps and running one small binary copied into the emulator using HostFS, which seems to be working fine. I also tried...

Re: Today I received.....

a spectrum 128k toastrack. It actually arrived about 6 weeks ago but has been packed away until recently. It's oddly beautiful in it's own way, and some of the spectrum games are great. Really enjoying R-Type, Castlevania: Spectral Interlude and Rebelstar.

Re: ABUG SOUTH 18 to 20 January 2019 (Hampshire) DISCUSSION THREAD

These dates are good for me as well. Incidentally, I'll be flying into LHR from Schipol and will be pre-booking a taxi to take me to and from the venue. Anyone else from the Netherlands interested in coming would then have transport to and from the venue, providing they book the same flights as me.

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

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...

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 ...

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 '...
