Re: MTX new Replacement mainboard ??

Ah, got the wrong end of the stick, I thought you were talking about a complete replacement fitting in the original case and giving the same functionality but using modern components. i.e. a fully physically compatible modern re-implementation.

Re: MTX new Replacement mainboard ??

Designing a new main board is indeed possible. But due to it's size, it's likely to be expensive and will probably need several revisions before a version that does not need modification wires is produced, making it expensive :o Mark Of course, the alternative would be to have a large but extremely...

Re: what did they smoke when they develop MTX Basic?

You didn't mention the error messages. Without rushing for the manual could anyone explain what the error "A" means, or "SE.D" Error code look-up tables and messages take up valuable ROM space, which is in short supply. Having said that some current software, such as Microsoft Windows 10, still ret...

Re: what did they smoke when they develop MTX Basic?

P.S.
The built-in assembler was inspired by Acorn BASIC, both Atom BASIC and BBC BASIC.
The front panel is an almost complete clone of the one on the Research Machines Limited 380Z.

Re: what did they smoke when they develop MTX Basic?

1) Spaces need to be in the right places 2) A LET commands most be used for variable declare or calculation. As said previously, normal until later "lazy" BASICs. It also allows the parser to be far simpler as you ALWAYS have a keyword followed by arguments. This also makes the parser smaller and f...

ZX Spectrum Next Kickstater

Just in case any of you are interested there's a Kickstarter running for an FPGA based Sinclair ZX Spectrum recreation with case designed by the original designer. They reached their initial goal of £250K in just over 24 hours and are now going for some stretch goals (one of which is for a ring-boun...

Re: Disk on a Chip ??

It won't be much faster as the data transfer rate is fixed by the controller. The only speed-up would be due to the lack of with latency seeking track to track. The controller reads a whole track at a time (or waits a specific period for the sector to come around before starting to read). The drive ...
