Slightly off topic for list although the rack and equipment are almost 20
years old now....
I got me a hand me down Compaq Proliant StorageWorks UE Rack. Basically it
is a rack case that can hold 14 drives. The case is secured to the cabinet
with two thumb screws (see attached pictures). These are like standard thumb
screws except there is a spring component to them as well (I assume to give
wiggle so it is easier to match screw to cage nut).
You can see pictures of the screws in this VCF post:

On my hand me down the one on the left is missing. I have looked and there
doesn't seem to be a Compaq part number (I think the screws are press fitted
into the metal frame so not really user replaceable). I don't think there is
anything special about the screw and I can always use a standard M6 screw
for the missing side. However, I'd like to try and match/restore the
original. I have tried googling for theses screws but I am not coming up
with the right item. I am guessing I am not using the right terms or names
for the screws. So does anyone have some broken/parts Compaq rack equipment
where I can have the screws? Or can point me to a source online to get a
replacement? TIA!

In the early 1970s a socket to hold multiple DIP chips was being sold under
the brand name DipStik. Up to six chips were inserted in a trough in the
socket, a top screwed on with thumbscrews on the ends. It had solder lugs
on the top and bottom for each of the chip pins.
We are restoring an old electronic device that was built in part with
these, but due to some corrosion we could use replacement DipStik units if
anyone has them.

Does anyone on the list have or have seen the stand that DEC sold with the
VT52? I'm just curious; does the stand screw into holes on the monitor or
does it just sit on top?
>From what I've seen before it just looks like an office chair base with a
top that is the correct size.
Thanks,

the 2.6.0 diag 6.0 bootable and 6.0 patches are probably the most interesting
has there been ANY posts about the Explorer simulator in the last decade?
I've also not verified any of them are what the label says
I ran into a couple that were overwritten. Some I know are correct, because
there were multiple copies.
Hi Ali,
I'm planning on a USB controller, but I've seen ISA projects that are also
microcontroller based so I think it wouldn't be awfully difficult to
replace the USB data pipe with an ISA one.
Zooming out, I have a list of USB controllers to build:
- Kennedy 9800 tape drive
- IBM 6360 8" floppy drive
- IBM <something> 5 1/4" floppy drive
My friends think it's silly, and they're probably right. =P

So, I used SIMH to do an install of a complete OS on
an RA81 disk. I would like to move this to a real disk
and try it on a real PDP-11. Is there a way to do this
using dd on a BSD machine? I tried but it created a
non bootable system. Well, actually, it starts to boot
but then fails very early in the startup process. I used
"dd if=filename of=raw-device bs=1024". Could it be that
the block size needs to be something else?
I know that VTServer and PDPGUI can move disk images but
it would take a week at 9600 baud and I think very little
likelihood of it ever completing successfully.

Hello everyone - since people have already been asking (we even had
someone call the hotel to try to register - that's some refreshing
pro-activeness), we can confirm the date of this year's Vintage
Computer Festival Midwest will be:
September 14-15, 2019
2019 will bring a NEW LOCATION which will be announced in the coming
weeks. So don't call the old hotel - they're already sad that they
lost us*.
Updates will be posted first to our site at http://vcfmw.org, as well
as our mailing list, which you can join there.
Thanks to all who have attended in the past and are considering it
this year. This one will be something special**, for sure.

Anyone who thinks logic starting from common sense has anything to do with
the workings of legal systems is likely in for a rude awakening at some
point.
