I have a Quantum 270 MB IDE that requires really small jumpers. Standard ones (e.g., Maxtor) are too big.
Anyone have any?
Thanks

Unknown on price but those are fast systems in the MIPS lineup. It's

TC??? It was a fast machine when it was introduced. fast compared to
modern with PII/233s and the like is a unfair comparison.

DECs linup was huge so that would be a large list (the option module list
was several very thick volumes and listed everything DEC had a part number
for)

crank up your web thingie and follow the PDP-8 trail. The DECmate series
is a PDP-8 in CMOS clothing. There are some BIG faq out there for that
one.
Look here:

It is not a BIOS trick. The extra 128K appears in the upper memory area,
>from D000 to EFFF. There was a special device driver available, USE!UMBS.SYS,
that turned this memory into UMB's if you were running DOS 5. Great for
parking mouse and network drivers in. The driver was written by a hobbyist
as a memory study project, it was available with the machine code source
so you could modify it for other computers. IIRC it should be on Simtel.
I also have a copy around here somewhere. I used to admin a network that
had lots of Philips XTs, NMS9100 and P3105 were the ones that had this
extra memory.

Well, I guess it's better than whoever used 0 text lines for a 0 line
response. At least with the 70 lines, you know what they're talking about.
With 0 text lines, and no response, your guess is as good as mine for what
they meant :-)

Quick question: what's a DEC DS200? (I'm assuming it means DECstation
200, but I'm also guessing it's x86-based and has no relation to the
larger MIPS-based systems).
Another question: what would be a reasonable offer for a stripped
DECsystem 5500? The guy seems to want a (IMHO) ridiculous price for it
(somewhere around US$900 as far as I can tell). He seems to think he can
sell it to someone that will use it to it's full potential, pitting it
against modern high-end machines. My offer, needless to say, was no where
near what he wanted! From what I can tell the DS5500 would be not much
more than a rare novelty (it IS a Qbus-based MIPS, after all), let alone a
competitor to modern servers. (I don't think it was even that much faster
than it's TC relatives.)
Also, is there a FAQ or something somewhere explaining common hardware?
I'd like explanation on the DECmate as well, but that seems like it would
be a FAQ by now.

Just a standard PC parallel cable should do the job..

Hmmm... If you're near Denver, there was a Plus/4 in the box at (iirc) the
ARC thrift shop on Florida and S. Broadway. Or perhaps someone who is
still in that area could pick it up for you?
