Don't confuse what you got with your DOS, with the hardware technical manual.

However - that "engineer" at the computer center should be reported :-)/2
(one-half a smiley).

On my shelf, and I just pulled it down, the manual says  Model 4/4p Technical
Reference Manual.  Cat No 26-2119.  (That should help).

And I'll be darned.  Just looking throug it and there is  a software addendum
with all the SVCs for the OS (TRSDOS 6 - alias LDOS).

If the local store can't help you might try calling Tandy 's National Part
center with the catalog number.  I don't have the number handy but your local
store should give it to you.

Hope that helps you and any others.
