There are good USB-to-serial adaptors, though (just in case you didn't know).

There is a nice IDE for the ZX Spectrum named "TommyGun": http://www.users.on.net/~tonyt73/TommyGun/

I'd rather prefer external commands over ROM extensions. For the ZX Spectrum there's an IDE solution called DivIDE, with a few different firmwares available. One of them is called ESXDOS, see http://esxdos.org/ or http://velesoft.speccy.cz/zx/divide/divide-esxdos.htm, and it uses external "dot comma...

But for the ZX81 I don't know... I use the z88dk (Small C language) in conjunction with Eclipse.

The z88dk compiles to an intermediate assembly file, then to machine code. The make file contains a line (which is commented out) to compile to assembly only. With my assembly optimisations I refered to the inline assembly you see in many places (#asm ... #endasm). It is not recommended to optimise ...

Hi Andy, the maze itself needs only one bit per 8x8 character cell; the items are represented by their row and column positions (i.e. 2 Bytes per item). I don't think I can save much here. Even the start screen is compressed (kind of a runlength encoding). If you understand C (and Assembler), you ca...

No more complaints, so I think we can say programming is finished - although you never really finish a program...
