My archive RSX11M+ system currently has 2) 9Gb and 1) 3 Gb drives on it.
Along with the 1GB boot, a CDROM and a ZIP. RZ25's get swapped more often
than the ZIP gets used now however.
It also has a quad density 9 track, TZ30, and a 4mm for tapes.
The only DEC item in it are grant cards and a DELQA

Just hang it on a SCSI controller. If it is an internal SCSI zip you can
set the SCSI id to whatever you want. If it is an external you will have to
use the CMD/Emulex or whatever firmware to map ID 5or 6 to something lower.
The other aleternative is to leave it at 5 and SYSGEN 7 DU devices to your
SCSI controller. (My archive system is that way) RSX11M+ V4.6 warns you
but allows it. In fact that system is doing another sysgen as I type this.
Had to add a few other devices.
I have routinely used various ZIP and JAZ drives on both CMD CQD220T/M and
Emulex UC08's.
However with the batch of RZ25's I got 6 + months ago I have gone to using
them as ZIP drives. They were cheaper than ZIP media. They also don't
eject themselves when you dismount them. I had to come back up to the
office a while back when I dismounted one my mistake from the house via
telnet.

Any idea who might have a copy of the modifications to the V6 source to
support RL02's? It'd be wonderful to put that into the PUPS archive.
This particular V6 system is indeed a very nice environment for someone
with a "small" 11/23 and RL02 drives.
That particular 11/23 system from UBC was used in the biology department,
judging by the non-system files found on the "user" disk.

Heh, PDP-11's are *light*... the last computer I had shipped to me, which
was only the CPU, disk controller, and hard drive, along with a terminal, a
graphics interface box, 2 terminal controllers and a rack of manuals weighed
in at 5700 pounds... The trick with shipping big stuff is to get it from big
companies, and then instead of choosing the shipper yourself, you ask them
who they use most, and have them coordinate it in-house... It's truly
disgusting how much of a break the big shippers get versus a single-time
shipment from somewhere... As an example, the 5700lbs of stuff cost me
$801.80 to ship, whereas my Burroughs B80, which they said weighs 800lbs
(yeah right!), they rated it as if it weighed 1000lbs, and for that single
machine it cost $817.07 or so... The rate on the 5700lbs was like 31 bucks a
mile and the other one was 81 a mile, but since the 5700lbs was shipped by a
major user of the carrier, I got like a $1500 "Incentive" i.e. discount...
Talk about highway robbery!

Hi, I've got several Unibus LP11 interfaces and I was wondering if anyone
was interested in trading a couple for M8207's (Q-bus version) of same? I'd
like to put a centronics printer port on my VAX and test out some code in
NetBSD for said port.

Hi everybody,
I'm (finally) getting around to write Part III of the "Collecting" article
on retrobits.com. I'd like to include a web page reference for parties
interested in getting more info (and subscribing) to the ClassicCmp list. I
found multiple info sites out there, but it's not clear to me which is the
most up-to-date and authoritative.
Can someone provide me the "official" web page for ClassicCmp? (Or at
least, where should I send folks who want to find out more...)
Thanks!

Never ship a PDP-11... way to heavy.

Yep! M8189 come in two flavors, the difference is the roms. The +(B)
will
boot MSCP while the older ones don't know the RQDXn Controller.
The 11/23+ (11/23B) was used in the BA23 box aka micro pdp11/53.

I've set up two RL02 and a RX02 in a 48" rack with BA11S and a few
filler pannels.
A 36" rack is very doable too. The RX02 is ~11in, the RL01/2 is ~12in
and BA11S/N boxes are ~6" you might get that in a 30" rack.
An 11/23 with 256kb and RL02s will run V7 if it's not the I&D version.

We obtained a whole pallet of these two or three years ago, and still use one
(too scarred-up to sell) for one of our test-bench monitors. When I asked
the seller about the nine-pin connector he said they required a "multisync
cable" and included them with the monitors. These are VGA monitors and I've
run them up to 1024x768 with good results.
Have fun!
