[net.micro.pc] Out of memory - MS-DOS question

scooper@brl-tgr.ARPA (Stephan Cooper ) (08/09/85)

I downloaded a public domain .EXE file last night on to my Tandy1000 (MS-DOS).
The file is 70,000 bytes or so.  the problem is that when I tried
to run it, the computer responded with:

"Program too big to fit in memory"

This is absurd, because I have 640K, and even prior to the memory upgrade
from 128K, I could run KERMIT, which was a .EXE file also, that was 80,000
bytes.

What gives?
I know the file downloaded correctly, there were no errors.
Does anyone know (or could anyone speculate) what is occurring here?
Does it have anything to do with the machine thinking it is an 8-bit
machine, or what?
Help?

Thanks,
Steve Cooper
