Re: SpectROM - Speccy emulator for the Pi co-pro

Totally agree that this is amazing! I find myself wondering what the limits are. Can it can handle the more extreme abuses of the CPC hardware, e.g. recent demos such as still rising (https://youtu.be/dDVAzMjA7bM) or phX (https://youtu.be/6wBwbRYL-F4) [And by the way, I know it's unrealistic (possib...

Master internal Pi CoProcessor plus VideoNULA...?

Just wondering if anyone has successfully fitted an internal Raspberry Pi Coprocessor board in the same BBC Master as a VideoNULA? I was considering getting an internal CoPro, but it looks like it would need to be in the same physical space as the NULA, because the CoPro board fits between the two i...

BBC Master 128 cartridge slot covers

Does anyone know where I might be able to find spare covers for the cartridge slots on a Master 128? Somehow I seem to have broken one of mine. (Anyone got any sitting around spare, hint hint?) I'm also wondering how you go about replacing them. It looks like the metal rod is held in place by melted...

Re: beebasm - incbin or EQUBs sometimes crash my program

Did you mean you're at ORG &900 or ORG &1900? There are several pages between &900 and &3000 that are used by the OS. This has some details: http://8bs.com/mag/32/bbcmemmap1.txt So e.g. page 13 (&0D) is the OS workspace and page 14 (&0E) is the start of DFS workspace, so if you're assembling code ov...

Re: Building B-em with Visual studio

In nearly all cases, one type shouldn't be cast to another where the desired is to use the same bit pattern for two different things. The "correct" way to do it is to have a union with both in and then use the member that does what you want when you want it. Or use reinterpret_cast! EDIT: Actually ...

Re: Need major PSU advice on my new beeb...

There's a lot of good advice here but in all honesty if it was me I think I'd be watching eBay for spare BBC Micro power supplies or even for machines that are sold as not working out whose PSUs are probably functional!

I'm really curious what the weird replacement PSU in your machine looked like!

Re: Question About Graphics Modes

I'm sure that the Acorn engineers would have considered it but everything's a trade-off between cost, speed, complexity, etc. If you dig into how the Beebs work at a hardware level, whenever a value is fetched from memory into a register, or sent to memory, it's done one byte at a time. The way the ...
