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: 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...
