Re: Making a case for the Replica I

Use some kind of standoffs to raise it up off the base and provide some openings for ventilation and it should be fine. Are you going to provide clear and reset switches on the outside of the case? Are you going to allow for installing a card in the expansion slot? I was planning making things as s...

Making a case for the Replica I

I'd like to make a case for the Replica I. Nothing fancy; just a wooden box, really.

Thanks in advance!

Code for waiting for keyboard input?

I've been trying to write some code for the Replica 1 where the program waits for you to press any key on the keyboard before progressing but I seem to be running into a wall so I thought I'd post my woes over here: First, I tried something like this: In Apple BASIC: 10 IF PEEK(-12271)>=0 THEN 10 20...

Clearing the screen

Besides the clear screen button and reset buttons, is there any way to achieve the same effects, i.e. via monitor commands?

Thanks in advance!

Re: Memory Address of BASIC RND Function?

Hi - thanks for responding. I actually dug around a bit after my initial post and found this: http://www.txbobsc.com/aal/1981/aal8108.html which isolates the random number generator in Apple I BASIC - BTW - Apple I BASIC's RND function is actually quite good! Back on topic - the disassembly is very ...

Memory Address of BASIC RND Function?

Hi, I've been looking around trying to find the memory address of the RND function in Apple I BASIC, mainly for the purpose of using it within assembly (I thought it'd be easier to just use a pre-existing RND function rather than write my own). Does anyone know where it is located? Barring that, any...
