this is driving me nuts. here is the excerpt:

Using the program "HEXLD", enter the following program, by inputting the symbols in the left hand column. Once the whole program has been entered, break out by inputting "S".

2600 LD H,00h
2E2A LD L,2Ah
C9 RET

here's the issue, i type the numeric code but the zx81 goes blank for an eternity requiring a reset.
Do i press enter each time or do i have to enter the numbers one after the other?
please help, this is making me very,very irritated.

Any ideas?

Edit: figured it out, why can't they just swap input with press enter?
zx81: great yet flawed
Zx spectrum: masterpiece that keeps on giving

(wish it weren't so expensive) :o
