Strangely enough, that is _exactly_ what I was planning on doing,
right down to the same Zork archive on retroarchive.org.

Yep... RedHat Linux in this case, and you don't have to rename
the files on the UNIX side if you add "L" after the filename...


READ V-2.22 (30-Dec-07) SIMH Interface V003
Read from "zork1.com" and write to "ZORK1.COM".

*This* is the tool I was after.

I think the key in this case is that I was using altcpm.dsk from the
swtools area of the simh webpage that doesn't have any sort of
read/write utility (plus I was using the 8080 altair emulator, not
knowing it might matter).

I built altairz80, then grabbed cpm2.zip from your blog entry, and it
looks just like what I was after.

Thanks for the pointer to the more complete software distro!
