Don't know if this is redundant but I found this at

Looks like some kind of project to write a Java interpreter for ZX81 Basic. By eliminating Arrays and "slicing" he omits one of the most powerful features of ZX81 Basic. String slicing allows for implementation of all kinds of other Basic functions, such as, LEFT$, RIGHT$, and MID$ for example.
Anyway, it's kind of interesting and a "Tutorial" on Sinclair 8K Basic. Maybe someone can even understand the Java at the back.
PS. I'm attaching the file but should I have just posted the address for the file instead.
PPS. Does anyone have the manual for HOT-Z/HI-Z they could post. I can't find it anywhere, although the program is available.
