cycles for a page copy

Sat Mar 22, 2014 2:52 PM

How many cycles would a typical 1 page copy consume? I am guessing around 8*256, but am not sure.

Hardware Idea

Mon Feb 10, 2014 12:31 PM

For all you talented hardware guru's out there :

I've often wanted a adaptor that would allow me to hook up any kind of small single board computer that has an IO pin breakout to the atari. Some way to map the pins into the memory space, and read and write to them. Boards like the Arduino's and the raspberry pi's, for instance. Seems like you could do an awful lot with an interface like that. SIO and so forth really is just too slow for anything other than emulated disk Drives.

Just a suggestion.

asm question

Sat Feb 1, 2014 2:26 PM

Hi folks. Well, I have a situation where I need to switch between, say, 2 banks of status variables.


status_reg_1: .res 2

count_reg_1: .res 2


status_reg_2: .res 2

count_reg_2: .res 2

.. etc


I need to be able to switch code accessing these variables from one to the other depending on another setting, without having to have separate code. The only way I could figure out was to set up a zero page 'base' register and use (indirect),y to access the variables. When I want block 1 I put block 1's address in there, when I want block 2 I put block 2's. Is this really the only choice?


WTB - upgraded/modded 130xe's

Hi folks. I am looking for a couple upgraded 130's. Specifically looking for vbxe, ultimate 1mb, other memory upgrades, and any other mods as may be.


Wonder if this person is on Atari Age at all...
