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

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.

Fwd: Computer for sale

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.

Hewlett Packard A2094 Monitor (Standard RGB ?)

by edick＠idcomm.com

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!

HP-IL/RS232C Interface

by thomas.h.lindberg＠se.abb.com

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
