Pi seems to be very interesting. I have to order one as well.
Speaking about the Multia; I've been playing with my Multias (166 & 233MHz) and found out that the rumors about it having thermal problems is true, but only when there is an internal disk drive. When using external disks, they haven't been overheating even if running Windows NT 4 for several hours. I think the development team was too ambitious when they placed a 3,5" drive inside the already crowded case. A 2,5" disk might produce a little less heat, but it seems to be too much anyway.
I'll do more testing soon like running VMS, Digital Unix, using add-in PCI boards, etc. A few years ago I installed and booted VMS and DigitalUnix. So both can be run on the Multia even with DECwindows.
If running the Multia without the (vertical) stand might cause more thermal load inside the case. Haven't tried that so far, but that's worth testing as well.
If anyone is interested, I can send him more information.

I see. I would've imagined they were worse. I do recall early in the
piece when the 233 ev45 (?) multia came out to replace the 166Mhz one, I
was called in when one went fut in the office at "Not Nice O'Clock" as
one was left on with NT4.0 and the "Okay to power off" (or what ever the
message was) screen which had been shutdown by one of our punters and
the idle loop was a busy one which after many hours of max current draw
had allowed the machine to put in a credible impersonation of the
Chernobyl disaster and had emitted enough toxins to trip the fire alarm.
There was words spoken with the employee and a call to DEC who amazingly
replaced it on the quiet. I suspect they were worried about fires in
offices for a while.

Actually, with the right fans, a Multia-shape/size case would be fine
with a n i7
in. They are very thermally efficient.

Hello!
For now. Given time I might have someone online and driving everyone
even more off the wall.
Incidentally Dave and Sampsa, those yeti outside your places have

I have to get an operational RM03. This is proving difficult. :-(
FYI: An RM02 will work too. Just a little slower...
Unfortunately they're just as rare anymore. :-(

I am using PIVAX(n) as my cluster nodes. I'd suggest avoiding it to
prevent confusion. :)

You can use almost any SMD disk that has a data-rate that do not
exceed the data/clock input of the masbus/SMD logic that is in the
RM02/RM03 and in a separate cabinet on RM05. My memory is vague,
but I think the number was 37mbit/s. Like a small 8" winchester..
(I think the fjutzu eagle is to fast, maybe swap LSttl for Fttl..)
(assuming this is 2020) I changd the panda moitor and DDRSMB to have a
table that describes the disc layout indexed by drive type read from
the masbus controller and I can dig them up for you..
