Do you have a Portable III setup disk? Can you image/zip it and send it to me? I have a
friend that uses one of these regularly as a MIDI device - works great, now he wants to
get his spare up and running.
Thanks,
Mark

Mark,
I gave away all my PIIIs several years ago. I don't know if I still have
a setup disk around or not. If I do I don't know where it would be and I
simply do not have time to search for it anytime in the near future. PIIIs
are reasonably common and someone on this list is bound to have the setup
program for them. I'm not sure but the same setup program may be used for
other Compaq computers as well so I'd look for the setup program for ANT
Compaq computer and try it.

I have the setup disk, but no suitable 5-1/4 drives. My classics are not
DOS-based :-)
I seem to recall there was a way to diskcopy using the HD as a buffer,
if this is true I could dupe the disk on my Portable III. Otherwise I
would need to get some 5-1/4 disk drives to install in another PC.
BTW - my portable III is having cmos battery problems. Does anyone know
(before I crack the case) what battery would serve as a replacement (and
is it soldered in place?).

DISKCOPY A: A:
(you will need to swap source and target diskettes a few times.
LOTS of times on older versions of DOS. WRITE-PROTECT the source disk
for when you lose track and put the wrong one in the drive)

Well, only once if the disk fits in RAM... Has nothing to with DOS version
unless you're running 1.x.

I could be misremembering (as usual?), but
ISTR it being around DOS 3.31 that they switched from using 64K for a
buffer during DISKCOPY over to using all of RAM.

I can't speak for 1.x because I haven't tested it. I wouldn't be surprised if
1.x only used 64K of RAM, though.

Could well be. Certainly IBM DOS 1.0 and 1.1 didn't do it. The first
program I wrote in assembly language for the PC, back in August 1981, was
a disk copy utility for IBM DOS that used all available RAM. I just wanted
it for my own use, but my employer was happy to have it for software
production. At one point I was asked to add a way to produce copy-protected
disks, but I didn't want anything to do with that.
Originally I only supported 160K disks, since that's all DOS 1.0
supported. I think someone else at the company updated it for 180K, then
320K and 360K. AFAIK the company went under before the IBM AT appeared
with its 1.2M high-density floppies.
