Atari 400 upgrades/mods

Recommended Posts

I have an Atari 400 (among other things) and I want to tinker.

 

I have already replaced the original keyboard with a raised key keyboard; given it a spiffy paint job (all black with a big red button). Though, I need to re paint it; the black paint I used as it turns out was not the best choice for the 400's plastic housing.

 

Next on my Agenda is: MEMORY

 

I know their were Memory upgrades made, but when I search on eBay for ATARI MEMORY or ATARI RAM I have never found any. Is their any parts I can rob off of my 800 to use inside the 400?

 

What specifically could I search for? Does anyone still sell these?

 

What other mods can be done? I would like to trick it out as much as possible; just for fun.

 

Any info or links would be appreciated. [/code]

Speech synthesis, keyboard mod, composite mod, it's looking like Popular Science '80 around here. I like it :)

Another small modification (now that you have a standard keyboard instead of the membrane) is to install a small 2-position switch through one of the venting slots on the underside of the case, and run one of the internal speaker's wires through it. The keyclick is almost a necessity using the membrane keyboard...but with real keys, it gets real annoying. You could just unplug the connecter, but you may want the option of being able to toggle it at will (since the speaker was sometimes used in programs). Naturally the cassette drive prompts and ctrl-2 character will not be audible with the switch off.

I was looking for something more than 48k; but thanks for the link. I'll buy that one if I can't find good instructions on a 64k or > mod.

 

The composite and stereo mod looks a little more complicated than anything I've done, but I may give it a go anyways. :twisted:

 

If I end up frying it I've still got a 48k 800.
