Sinclair ZX80 / ZX81 / Z88 Forums

I have a couple of TS1000's, a ZXMore, a ZXPand and a ZXPand+. I primarily use the ZXMore with either ZXPand+ or occasionally ZXPand. Do I need to buy a EPROM burner, EPROMs? Is there any documentation of what to buy, how to do it, etc? I would love to use this fast ROM.

If I remember correctly. You kan load any ROM into ZXmore. I know this from ZXblast, which I have. And ZXmore and ZXblast should be quite similar.

I have the fast ROM in instance 3, and regular ROM is instance 1.

You don't need an EPROM burner. Just "load" that rom from instance 0 LOAD menu to address 0 of any other instance. The LOAD menu of instance 0 shows also an example to "LOAD" something into FLASH rom of ZxMore.

It should be in the ZXmore manual. It was in the ZXblast manual.

What license are these changes published under?

Feel free to use them, there are no restrictions.

Many thanks! Please feel free to help yourself to anything useful here: https://github.com/cheveron/open81/tree/Version-2.5

Dear All,

I hope you are well despite the pandemic.

Here is the last X2-ROM variant - let's see, what is changed:

- the Babylonian (or Heron's) square root method (from the SAM Coupe ROM by Andy Wright) shared by aowen is included;
- i tried to solve an old "problem": the flicker free PAUSE;
- good news for Siggi & Joachim: the renewed CLS (is a bit slower but) handles the too long D-Files.

The zip file contains the new ROM image (zx81X2m.rom for zxmore) and its source code, the changed/patched routines in a separate folder, and some test programs.


Cheers,
Zsolt

Cheers Zsolt

Many thanks Zsolt.

Time to fire up the burner!
