I tried, fellas.

 

Really tried.

 

But when loadiing DOS + handler, with the way that the extant R: handlers load, there isn't enough RAM to handle the 8K needed for the high resolution display + the additional bytes needed for various bits of scratch memory.

 

I'm sorry. while the PLATOTerm cart is 16K, it needs a bit more than 16K with DOS loaded. 

 

(without DOS loaded, I was able to shove the memlo down far enough that it runs fine, but I can't dynamically do this without drastically rewriting the cartridge init code.)

How many bytes are missing? Do you use already http://www.mr-atari.....Atari/LiteDOS/ ?

it would work with LiteDOS, but I was really trying to get it to work with standard DOS 2.0/2.5.

LiteDOS will give you 4k more RAM to play with.
Running plato on a 400 would be awesome...

 

But since, what I see plato does, you only use DOS to load the R:driver:

You can easily load any driver, made boot-able, from disk, avoiding any kind of DOS.

Giving you even 6k more.

Yeah, we can do that. Just need to make a sort of stubby loader for that. I'd LOVE to actually shove the handlers onto the otherwise unused banks of the cartridge alongside the touch handlers...

 

hmmm
