Re: Please Introduce yourself...

Welcome.

If you've got a CFX already, then Andy Key has a memory card for the MTX, it won't increase the memory in basic past 64k though. (Not that there's any software out there that needs more than 64k visible to basic.)

Re: [MAME] Emulating the MTX

Silicon discs have a driver - SIDISC.COM that needs to be loaded first. It's not compatible with Andy's RAM disc code though, they both use the same drive letters and high memory. There's 2 copies in the ZIP along with a re-built source that formed the basis of the SiDisc drive built into the CFX 2 ...

Re: [MAME] Emulating the MTX

You'll probably want Andy's REFORMAT.COM. It works with pretty much all the drive types.

Re: New tape cleaner tool

That is clever, so much more readable output than my program's stream of 0s and 1s.

Upgraded 65C02 Co-Processor - work in progress

Elsewhere on the forum, Bill asked for details of my latest project. It's still very much work in progress, but it's a upgraded 65C02 co-processor board for the MTX plus. The original 6502 board that we demonstrated at Memofest in Aberdeen runs HiBasic 3 from the BBC 2nd processor and passes all the...

Re: New tape cleaner tool

I've been sidetracked by another hardware project. So "spill the beans", your projects are always interesting. I'll see what I can do photo wise (edit: see http://www.mtxworld.dk/memorum/viewtopic.php?f=17&t=416 ). In the mean time these are the quick and dirty clean up tools in BBC Basic I did man...

Re: New tape cleaner tool

It's great to see someone getting somewhere with these, I've been sidetracked by another hardware project. I assume that this is an earlier version of "Karate King 64" which is in Andy's distribution. From a long distant memory, I seem to recall the 32k MTX500 version of the game was on one side of ...

Re: MTX 512 loading problem

There's a few options: The "modern" hardware route: a) SD card storage www.nyangau.org/rememorizer/rememorizer.htm b) Compact flash storage*** http://primrosebank.net/computers/mtx/projects/cfx/cfx.htm or tape replacement: WAV file recordings of some of the software can be obtained from http://primr...

Is there a PCB for the MTX 6502 BBC Co-Processor unit ?
No PCB, all 3 prototypes (1 MTX, 2 MTXplus) were hand wired, with only 7 chips and a few other components it's not a complex board.

The schematic is on Dave's site if anyone want to do their own.
