Right... identical CPU, no provisions for external expansion (but you
_can_ squeeze a Unibus cable out it if you're careful), RC25 disks - fun
but a pain - one motor with two disks; one removable, one fixed, 25Mb each.
I used to have an RC25 cart with VMS 5.0 on it, so I know it fits, but I
lost it and the machine when the business it was resting at closed with
so little warning that I couldn't get it out. :-P
The 11/725 case is a bit larger than a BA-123, but the aspect ratio is
similar.

Sounds just like a White Data Systems Vertical
Carousel... never got to work with one of those,
but I wrote lots of code to move the WDS Horizontal
Carousels back in the 80s...

Ho Ho Ho! Last time I pulled cable (raceways amongst others) was in
college... somebody else gets all the fun now. Not that I mind work,
Hell, I love it, I can watch it all day!

I work with them every day and don't have such problems. I rather
like 'em. The ones I use are made by Newton...might wanna check 'em
out.

Oh, they're great if you like your cables getting sliced
up as you pull them through; pulling the raceway tops off
(the alternative) is no fun either.

You forgot the Vaxmate a 286 box that was mildly PC.

I had the same agreement... Some new "stuff" came in so, I tossed the old
"stuff" out. Now I live alone :-)

Meyers Computer Services is an A-1 operation, so
I can heartily recommend them if you ever want to
do business with them.
You may recall my post about a drive I bought on
haggle. The drive in question arrived sans three
SMD chips from the interface PCB, and would not
spin up. The replacement arrived very quickly
even though I told them to save money and go
slow-boat-to-China with it. The replacement has
the chips that were missing from the first one.
I haven't tried it yet, but I already told them
no big deal if it doesn't work. There are apparently
a ton of these flooding the surplus market right
now, and I've got another coming from another source
(for less than this one cost), so I'm as happy as
a pig in shiwhroishafowehfofhaew;fhawef

Since we're on the topic of collections, I have this question:
How does your significant other/spouse deal with your hobby, if
you have one (a SO, not a hobby), and what "concessions" do you
make to stay in their good graces?
Myself, I have the aforementioned 2-car garage, plus we have an
"agreement" that for any "big" item, I have to get rid of an
equivalent amount of stuff, whether it be modern or old.
My SO just about throttled me when I mentioned "yeah, I picked up
a couple more machines over the weekend" when I picked her up at
the airport after a weekend trip a couple of years ago. She
didnt quite think that the 35+ Sun SS1s, 3/80s, 3/50s, 3/60s,
keyboards, and monitors, in piles in the living room, were a
"couple" like I did. 8-) Of course, I lived in a 1/1 apartment
at the time, so she was placated when I sold off most of the
systems and bought her a leather jacket instead.
Bill ("No, honey, please ignore the semi trailer and the forklift
backing up to the garage...")
