I’ve attached different AUI transceivers to Sun3/E SCSI/Ethernet at least
100 times while running and nothing happened. The Sun 3/E prom has on board
diagnostic which could provide more information on the failure.

Bill, did you ever cross paths with Dan Nissen or Karen Nissen? Friends
from U. Wisconsin (and Karen also worked at WisDOT for a while after I
started there, before they both went off to MPLS.)

Yeah, there's good reason more modern AUI-based Ethernet and more modern SCSI
systems use resettable polyfuses...

I have also seen the SCSI terminator power fuse blow when the terminator is
hot plugged.

Oh yeah, NetBSD 9.0-stable 64-bit also only takes a few seconds to boot on a
Raspberry Pi 3B+. It's easy enough to just throw on an SD card and try out.
Alas
One thing that would make it much easier to experiment with SIMH in scenarios
like this is if its build system wasn't horribly redundant. It genuinely looks
like someone looked at make and said "How can I turn this into a procedural
scripting system?" and then wrote the SIMH makefile in that

In the mean time I put my three little Ultra 10s to hard work and finally I
solved the mistery:. One ultra10 has a creatir3d, one has an elite3d with
creatir driver assigned, the last one is using the on-board ati video card
(no UPA card).
Here is what I did:
- installed openbsd 6.7 without any

Hi Jules,
Still interested to find out about powering the Melcor SC-635?
I got one and succeeded to power it from 2.2 to 3.0V
There is a switching regulator on the PCB (AS1930 from Astec International)
that generates negative voltages (as referred to the negative side of the
battery: -12.4V ,

There are multiple libraries for bare metal execution on the Pi, there are
trade offs with device support.

Not that I know of.

I made a set of stubs to compile and link a simulator without the SIMH
framework. Empty

Haven't seen anything, but Linux can
Has SIMH been ported to a low overhead (instant-on) platform?
I ask the question because the startup time of Linux is distracting when

Something that I thought the folks here would appreciate: a fellow in Dubai is
trying to keep a full-motion Boeing 737-300 sim (from 1991) running.
The main host machine is a Sun/3E, connected over Ethernet to the operator
workstation which has 2 Sun/3Es each with a cgtwo powering a CRT touch
