I have a T420 which came with a DVD/CD burner. I later replaced this with
a Bluray drive. To make the swap, I had to remove the side catch and rear
stub from the drive. I'd like to swap back to the DVD drive just in case
so as to avoid any needless wear on the blueray drive's mechanism. To do
this, I'd like to get another catch and stub. The problem though, I don't
know what these things are actually called, nor do I know of any sort of
part number to look for. Does anyone here know anything useful on
tracking down these things?

Hi,
Does anyone have any recommendations for a '90s era PC that has PCI and
ISA slots? Ideally I'd like to have EISA slots too. ? At least I
think that's what I want.
I'm developing an itch to play with older networking equipment, Token
Ring, FDDI, etc. and I suspect that a machine running '98 / NT 4, or a
Unix / Linux from the late '90s would be a good candidate to mess with
things.
Obviously I'll need two devices to communicate. I may end up looking
for an older Cisco router that supports the various interface types.
Years ago I had a Compaq desktop that had PCI and EISA slots. I'm
trying to re-acquire it from the friend that it went to.
Does anyone have any Pro Tips on things to look for or avoid? ? One of
the worries that I have about the aforementioned Compaq is that it used
proprietary components (the keyboard connector looked like a PowerBook
SCSI connector) that would be hard to replace if (read: when) a problem
develops.
I would greatly appreciate any tips / tricks / things to avoid.
Thank you in advance.

A friend and colleage of mine says he has two TRS-80s available, or
perhaps very soon to be available, in Ottawa (the capital of Canada).
He says he knows very little about them; apparently it's been something
like a decade since they were even taken out of the boxes. For further
information, I'd suggest contacting him directly - I haven't even so
much as seen the boxes they're in. lucasb at gmail.com is the address he
gave me to pass along.

I have a bunch of HP machines, which are still in heavy use (although upgraded
to Celerons with the PowerLeap iP3/T thingys). Vectra VL6/S8's and VLi8s. I'm
very fond of them - solidly built, well engineered, quite reliable, etc. The
VL5/S4-5 and VL6/S6-7, etc are also OK (very similar, same build quality), but
I prefer the /S8's as they have the 100MHz memory bus.

I have a later TI 990/12 system with a dead power supply. Looking drawings or schematics andI believe there in the hardware reference manual.? The one manual on bitsavers? under 990/10shows a older type of power supply.? Mine is basically? all on 1 board.? The chassis is a 990 A13
Thanks, Jerry
Fabri-tek was a common supplier for core memory. Many companies used their memories. Fabri-tek Instruments became Nicolet Instruments in 1971.
I'm not sure one could tell what machine it was used for. It was a common memory system. They did make a lot of memories for military use.

SDS built a 24 bit system with Parity too, the CDC 924 was 24bit,
there were a few others and I believe but can not recall for sure, a
navy 24 bit maybe done by ERA.

Does anyone have any software for developing for the Intel 3000 series? I
bought some parts on eBay and am contemplating a bit-slice PDP-8 or DG Nova
for fun.
Bitsavers has some 3000 series manuals, but I can't seem to find any "bits"
of software. Looks like CROMIS is the cross microprogram assembler, which
looks like it would've run on an MDS-800.
Apparently the CROMIS sources are in Fortran IV, and provide both XMAS and
XMAP, the cross microassembler and a programming file generator,
respectively.
Anyways, if anyone has any bits of Intel 3000 development software or
simulators, I would be very interested in checking them out.
Thanks!
Kyle
