You mean this Forth doesn't include the C@ and C? words? It's seriously 
broken if it doesn't! The former is the equivalent of Peek -- it's 
Character Fetch. It takes an address from the top of the parameter stack 
and replaces it with the 8 bit contents of that address. The latter is 
best explained by its definition

: C? C@ . ;

In other words (sic) it takes an address from the top of stack and prints 
the 8 bit contents of the location using the current number base.

I suspect, therefore you do have a way of reading out that EPROM, although 
unless you've got a serial interface on your ZX81, it's not going to be a 
lot of use.
