The BBC master is about the same width, but way deeper, and probably equally hard to find. The original IBM PC keyboard would have been a similar size, but i whether that's similar enough, it also has the same availability issue. Or there's the outside of the box thinking - and cut down a patio set ...

That's a bit of a jump from "It's not practical to re-write the OS" to "the machine is crippled." Using Jon's systems as an example ( http://www.mtxworld.dk/memorum/viewtopic.php?f=10&t=505 ) How many pople who've just spent £275 on a vintage system in A1 condition would be willing to take a knife t...

Something like That would test everything, the function keys return codes 128 to 143 depending on shift.

The first line turns off the break key so you can "test" that, but it means reset is the only way out.

From what I've seen in photos the chip select for the piggyback rom is "yellow wired" to GROM using a convenient via to anchor it. That's why the V1.1 Magrom needed an extra chip, to decode ROM 6, compared to the original that uses GROM, to make it work with language roms. As far a CFX goes, that on...

Any chances for e.g. an improved ROM today? Hasn't anybody considered something like that? :roll: Leaving aside the reluctance of MTX owners to open their systems, (external fit CFX and Magrom outnumber their internal cousins about 4 to 1), and the small number of "active" Z80 coders in the MTX sce...

So... England's COVID restrictions are currently scheduled to end in June, meaning they ought to be well out of the way by the "traditional" early Autimn Memofest date. Now I don't want to stop anyone else volunteering, after all I've been the host a couple of times before. However, to get the ball ...

Andy's put VRAM snapshot and CPU snapshot diagnostic options in Memu. I don't think there's an all in one dump everything option or a reload VRAM from snapshot, though I'm willing to be corrected. For those games with copies in MTX file format, then yes they can be "processed" on modern kit to "clea...

Welcome :D Andy's put an extra 48 row mode support in Rememorizor, and supplies a patched newword (N48.COM) to use it. Useful for editing files, though I'd be the first to admit developing mostly on more modern systems, and then pushing it to the CFX for testing on the MTX. From Andy's site: ACRT is...

Yes, I know how cramped the ROM is. Going back to the code that you wrote for EXEROM, could a user written block of code be used to replicate the USER READ commands to load the EXEROM and game ROMs? It's doable. Starting with the the basic/assembler mix of the original loader: 1 GOTO 40 10 CODE 800...

Hi, I'm sure that you can load blocks from tape, it's just that I'm not sure how to do it. I am also sure that someone else will jump in here - Martin perhaps? regards Dave Details of load/save blocks posted on the other thread. Unfortunately the MTX's built in tape facilities were just the bare mi...
