Hi all,

I have just received a Tandy 200 to go with my 100 and 102. It seems 
functional, but leaves me with an odd question:

I have one of Birt’s Backpack drives, which works perfectly with my 100 and 
102, using the TS-DOS loader included on the SD card, and referenced in the 
Backpack manual. Unfortunately, I don’t have an option ROM with TS-DOS, so I 
loose 6K or RAM. On the 100/102 that isn’t too bad, but on the 200, it leaves 
insufficient RAM for the documents I am producing.

So, I thought, why not load TS-DOS into one RAM bank, and the documents in 
another? Except that I don’t see where TS-DOS can load a file, while it’s 
running from (say) Bank #2 on the 200, and save the file in Bank #1. Or, save a 
file from Bank #1 to the Backpack, while it’s running from Bank #2.

Is this even possible, or do I need a TS-DOS option ROM? I do have a REX#, but 
it doesn’t seem to be functional in the 200. I was hoping to get one of Birt’s 
Dial-A-ROMS, but they don’t seem to be available at present.

Any ideas?

Thanks,
Andy
