Seem to remember RMIT's EduSystem used mark-sense cards as the Tech
College couldn't afford the the teletype/papertape configuration. Was
there a -15 version?

I've mailed Henk a copy of Ontrack Disk Manager.

I found the SET320P.EXE program on the COMPAQ site, and it allows
several items 'normally' found in a BIOS to be manipulated. Alas,
there is no field to change the hard drive parameters nor the type!
The disk manager was a good idea, I have one old 486 PC with a big
Western Digital drive, too big to be supported by the BIOS, and the
EZ-DRIVE disk manager works perfectly here.
However, EZ-DRIVE only accepts to work with Western Digital drives,
and the 2.5" hard disk that I have is from HP. The disk manager
also wants certain settings for the hard disk in the BIOS ...
Still not giving up / one more try: could somebody point me to a
site that has a non-commercial disk manager (for HP or not restricted
to specific HDDs) or even better e-mail a ZIP with such disk manager?
TIA,
- Henk, PA8PDP.

You can get silica gel in bulk from any laboratory or craft supply
house that caters for chemists, biologists, microscopists, mycologists
(mushroom collectors) or people who do flower arranging (and drying).
It's not always as cheap as you might think, though.
I get mine by asking our techs to throw each little bag that comes with
a PC/monitor/harddrive into a box at the end of their bench. Ask your
local PC shop to do the same?
Bear in mind that it works by absorbing (pedantically, adsorbing)
moisture from the atmosphere in the region you're trying to protect,
and there's a limit to what it will soak up. Some of it comes with an
indicator: usually cobalt chloride; pink when moist, blueish-purple
when dry. You can drive off the moisture by warming it in an oven at
130C for an hour or so (the time tends to depend somewhat on the
quantity and packaging).

Does anyone have any experience running MS-DOS 6.22 on VPC? I've
managed to get Win3.1 running in SVGA mode at 600x800, and I've got
some of my old DOS software copied over.
What I really want to know how to do is access the CD-ROM, Ethernet
Card, and if possible get video drivers for the S3 card that VPC
emulates. Oh, and I need a mouse driver for the PS/2 Mouse so I can
run a couple games :^)
In case anyone cares, so far I've gotten the following working:
AROS
BeOS 4.5
BeOS Max
MS-DOS 6.22/Win 3.1
Windows 98SE
Windows XP Pro SP2 (it came with this, so it had better work)
Obviously only Win98 and WinXP support the cooler features such as
mapping folders on the Mac as network drives, and printing to the Mac
printer.

Yup, that's them. And that's about the prices I remember seeing. Not a
bad price if you need a large quantity, but I found them a little pricey
because I only wanted about 50 at the time.

I'm sure I've mapped DOS in VPC to both shared folders and printers.
Although this would have been with much older versions of VPC (v1, 2 or
3). I do know for sure that I have run WIn95 with both.
But who knows, this is now MS VPC, so I'm sure they made any features
that might be useful work exclusively with whatever version of Windows
they want to make you use.

Hi Lawrence,
I was just perusing the ClassicCMP archives and noticed a post you
made on Fri Nov 15 20:18:14 2002 about the Micom - a computer that was
very much ahead of its time - and wondering if its founder Stephen
Dorsey was still alive. He is very much alive and kicking: he's in
Montreal and now the president of BabyTEL, a major Voice-over-IP
company in Canada and subsidary of Voice & Data Systems. I met him
through a business connection - truly a fascinating man, and still
working in fields that are ahead of their time (he's been working at
VoIP since the early 90s!). Let's hope he get rich this time.

ULine sells them. Although I seem to recall when I looked into them they
weren't super cheap. But that might have been because they make you buy
them by the case (per packet cost is probably dirt cheap, they just make
you buy 2000 packets at a time or something like that). Its been a while
since I looked at them.
