Only on the system that it was designed for! This is typical of the
hype that manufacturers are spewing!

Those 8" drive prices are for new-in-the-box never used drives,
incidentally. If I'm charging a customer $100 an hour to go on site
and service their machine, I'm not doing them a favor by installing
a heavily-used drive to save a few bucks.
And if you want to compare prices, maybe you want to look in the back
of a late-70's BYTE, see that a Shugart 801 sold for $350+ back then
to hobbyists, adjust for inflation since then, and arrive at an adjusted
price today of over $1000 for a new Shugart 801. California Digital's
prices are a bargain by this method. I certainly can't justify keeping
parts in my inventory for over twenty years!

Anybody out in the Midland, Michigan area, here's a Heath H89 available.
Would seem to be a very good complete system for a person who wants one!
It's likely CP/M as it's got the soft-sector H37 floppy drive as opposed to
HDOS which typically uses the H17 and 10-sector floppies. Contact Don
directly of course:

I seriously doubt that the sync signals have any effect at all on the
"stereo" vision effect you may observe when playing some games, etc. In
fact, at the risk of saying "bah, humbug" about what's obviously a popular
feature, the monitor, as far as I can see, can do little to help what's
being displayed on it. Of course, being bright, sharp, well converged and
linearized, is always better than not.
Using a fixed ffrequency monitor on a PC is always a pain in the *ss. No
matter how diligently the vendor of these cards calining to make it work
have pursued the features, there's always some sort of problem, be it the
mouse, the floppy disk, something is going to screw up. I'd advise anyone
contemplating this sort of monitor to get an a/b switch as sold by MEI and
countless others and use the BIG monitor for WIndows or whatever they want,
and use a $10 vga from the thrift store for everything else. That should do
the trick with minimal pain. That way they must have a video card capable
of supporting their monitor, but don't have to have a custom BIOS rom on it
to support the BIG monitor. IF the card you are considering will support
the non-interlaced 1280 by 1024 at the vertical rate, or close to it, for
which the monitor was designed, you should consider yourself lucky. These
won't be cheap, because the video DAC has to be very fast, (run the
numbers!) to cough up pixels in 64k colors at 1.12x the product of the
horizontal rate and the number of pixels. That $160 card which was
mentioned yesterday on this thread was capable, but $160 is not an ordinary
price!

Uh, Don, the 110 and 110+/"Portable Plus" are MS-DOS portables.
They're not PC-compatible but/and they don't run CP/M.

Don, Joe,
I might be able to help both of you!
I believe that I have a manual for the HP-IL RS323 device somewhere, probably
also the device itself. I'll check and revert.
I also have an old HP 110+, the HP-IL printer that goes (went) with it, a HP-IL
floppy drive (720kb), and a HP-IL GPIO device (General Purpose I/O).
I'm willing to trade the HP-IL RS232 device for (almost) anything for the
HP110+, S/W, firmware, or the memory expansion board. Suggestions, please!
Thomas
I spotted this in a surplus store this morning. Does anyone want it?
It's a Tektronix manual for the option 37, 38 and 39 MODEM that goes in the
4010 series of terminals. The manual looks like new. $10 plus shipping.
Let me know if you want it.
Joe
Jerome,
New Mexico parallels almost the entire border of my state... I defintely am
interested.. I lack a PDP-11, though I have about 16 or so other minis. Let
me know more info.
