At the time it was developed SCSI was maybe SCSI-1 or II and way short on
perfomance, limited in number of possible connected devices and short on
cable length. DSSI like many of the DEC storage interconnect was trying
to
address problems like cable length (wanted longer), rate of
transmission(faster)
and cluster interconnect. It's also a protocal and within that it
addresses
best ways to move data faster and route it.

Distributed

Yes.

Still looking for a real 68000 Mac to play ZeroGravity on (68010 would
probably work too but let's stick to what I know :-) Anyone getting rid
of a Mac Plus or original Mac Classic, or maybe even a 128K Mac? ;-)
Seriously, please reply off-list if you have one you're willing to sell.

I, too, have one of these kicking around. Mine has a bad Ball Monitor inside.
I believe the MDS 225 is the Development System III mentioned in Joe's
documents in an earlier post. I used to play with these about 9 years ago
when we bought truckloads from Intel.
If you have questions contact me off list. Most info has been covered on the
other posts.
I think it is worth collecting. There are not many in the hands of hobbyists
and collectors. I used to have CPM for this system but I am not sure I still
do. If I find it I will let the list know.
I bet InBus Engineering still has cards and parts for these systems, if not
docs and SW. I know I sold them thousands of dollars worth of parts,
especially for the 310 systems many years ago. I still have some 310 multibus
systems & parts.
Their contact info is :

Unfortunately they realize they have almost the sole supply for these old
systems and their prices used to reflect that. I haven't talked with them in
years but they still advertise in Compu-Mart and the Processor.

Hi,
This may be off topic but I just have to brag
I just received my cobalt cube today whoo hoo.
Its is not 10 years old yet but has just been made obsolete by SUN who
bought Cobalt a couple of weeks ago.
It's brand new never openned in the original box.
I just can't wait to setup my server. But I have to for now though.
That's it
Thank you for reading, you may return to your normal occupation now.

Subject: IBM System 34
We are going to dispose of several terminals as well as System 34 - we also
have books from the initial installation, the system itself, plus CMAS
software. Would someone in the Illinois area be interested? I am merely
investigating this possibility as a way of not adding to our landfill and
not destroying something that a collector might be interested in. The
System 34 is still installed and not quit ready for disposal, but terminals
are. Is this old enough to be of interest?

MVII is a Q-bus machine and like it's compatable Q-bus PDP-11s that
went before and during its a reasonably easy bus to interface to and
DEC did a fair job of makeing the documentation for it easy to get.
Designing a PIO SCSI card would be easy, DMA a bit harder but
there is no secrets there either. Programming is another thing though
as the Q-bus is an annex of the processor address space and DMA
between memory (on private(PMI) bus) and QBUS devices is more
complex programming. However RQDX (disks), DEQNA/DELQA (NIC)
do the dma trick so that is already known.

About 6 years I found that Radio Shack has a plug in the cigarette lighter
converter to 110v. We were able to power a small color TV and Toshiba VCR
for a 4000 mile in 3 weeks vacation with 3 small kids. The converter is
fused and sells for about $60. The van was also dragging a small 2 wheel
trailer. You could feel the engine labor sometimes in the mountains. I
took ear plugs, disney movie music rots your brain. My wife still uses the
converter to recharge her cell phone in the car.
Now parent of 3 partially grown kids, two in high school.

I realize this falls into the category of stupid
questions, but:
The RL02 has to be plugged into a *live* RLV12
before it will spin-up, right?
