Some of the Chroma interface functionality is via Z80 CPU IN or OUT instructions (I/O ports). There are no BASIC equivalents, so this has to be done in machine code.

Or with the help of the Power Basic made by Swatosch.

Thanks Mark. Would a Spectrum Z80 work ok?
Not necessarily. Spectrums are quite tolerant. But if the spectrum Z80 is fine then yes, it's going to work.

Re: ZX Printer Belt

Owning a 3d Printer I am one of the guys who would have been trying to build one myself. But experimenting with settings of the printers like temperature, speed, resolutions, material etc. is very time consuming and if I can buy a belt I will definitely prefer that. Can all this wait until the Brexi...

Will it work with a ZX80 though?

Regards,

Shaun.
I'm afraid not. The ZX80 has no /ROMCS line to disable the internal ROM which is necessary to avoid ROM shadows.
Also the (standard) ZX80 has no NMI generator which again is mandatory.
The ZX80 Core should work with ZXBlast

I've just found out about the ZXBlast - wondering what would happen if I plug this into my ZXMore? Are the two devices compatible?

Regards,

Shaun.
No. ZXBLAST is the ZX81 Version of capabilities that are included in the ZXmore. So they would disturb each other.

Re: Bus Library

I now have the ZX TEAM in EasyEDA, but there are no SCH Libs or PCB Libs. Have you forgotton to make them public? I'm afraid ZX Team is mine. Just a test before I finally bought Eagle. His must be ZX WORLD. By the way, I do have some eagle libraries with ZX81 items if anybody is interested. Kind re...
