Re: How close is the ZX80/81, Jupiter Ace and Spectrum in machine code backwards hardware compatibility?
Comparing a ZX80/ZX81 with a ZX Spectrum: there are significant differences in hardware and in the BASIC. The memory map is not too much of a problem except that in a ZX80/ZX81 the 'display file' is determined by software. But in the ZX Spectrum, it's fixed in the 'lower' RAM area. It also is much ...

Re: 16k Sinclair issue 1 pack
Try this game without RAM-pack.
Does the ZX81 show the right picture then?
You can do it, the game is my 1K 3D Random maze (Game 5 of 81 1K hires games)

Re: How close is the ZX80/81, Jupiter Ace and Spectrum in machine code backwards hardware compatibility?
Is it a matter of different address mapping, such as it would work if you had a system that remapped the address space when running a program for another system, or are they fundamentally different? My emulators remap all memoryaddresses up 32K. In (very) short: ZX81/ZX80 #0000-#1FFF ROM #4000-#7FF...

Re: How close is the ZX80/81, Jupiter Ace and Spectrum in machine code backwards hardware compatibility?
Hi, I'm curious in how backwards compatible programming in machine code, is between hardware in the ZX80, ZX81, Jupiter Ace and Spectrum? Define compatible. As said. Storage on tape is already different so you need additional software to load from tape. Another problem is the fact that ROM is on th...
