Back to the old BASIC days

I'm currently having a bit of fun revisiting my younger days

I'm sure many of us remember typing in listings out of magazines, and I recently stumbled across this - not quite sure how?.


Anyway, as I started on 6502 I thought I'd have a play (particularly as you can cut and paste rather than typing).

So I downloaded a 6502 emulator PC-BASIC 2.0.7, and gave it a try - bearing in mind I'm not running on actual 6502 hardware, so I've no 6502 machine code to disassemble, and I've no idea where the peek instructions are actually reading?. But I expected it to at least 'work'.

Anyway, needless to say, it didn't go well, if anyone cares to look at the code it's absolutely littered with glaring errors, and I'm still working on it

How about an emulator? Different than you have.

I don't think it would help, there are some horrible glaring mistakes in the listing - such as using '+' for multiply

It's now working fairly well - as far as I can tell - it's been a bit of a struggle, it's been decades since I've used an old style BASIC.

Well still playing, as I've no idea what 'peek' does in the BASIC interpreter I'm using, I thought I'd try VICE, running a C64 emulator - unfortunately I can't ctr & paste the code, as the C64 needs it to be in lower case, even though it appears as upper case. So I'm currently retyping it - slowly

I have a 68HC11 with BASIC burned into it. In a homemade Al box. It has not seen power for 35 years.

PEEK gets the byte located at the specified memory address
POKE sets the memory byte at the specified address.
