Started learning Machine code: Am i doing this correctly?
Re: Started learning Machine code: Am i doing this correctly?
Some excellent links there. Many thanks Martin and Blittled.
Re: Started learning Machine code: Am i doing this correctly?
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?

In Heck, there are two options for perpetual torment:
Eat the Puckerberry and suffer for eternity:
drink nothing but a cocktail of The Last Dab and Mexican Cake blended and served with
habanero slices

What would John McCarthy say...?
In all seriousness I'll read through this thread and pick up some tips!
Good luck!

Thanks Shaun for this advice!
Crayon21, thanks for this… ASM tutoral.

A RAND USR 30000 give me a 0/0 prompt… (without RAMTOP to clear it by a 'NEW' command)
30000=$7530
Cool !

"26" n/l
"00" n/l
"2E" n/l
"2A" n/l
"C9" n/l
"S" n/l
RAND USR 30000
Not:
"2600" n/l
"2E2A" n/l
"C9" n/l
"S" n/l
RAND USR 30000

I would assume they would give the same results.
If you use
Code: Select all
LD B,01
LD C,02
RET
Code: Select all
PRINT USR 30000
Code: Select all
