Hi Folks,
Propably not yet 10y old so slightly OT. yet .....
I got a SynOptics 810M ethernethub about 9 month
ago and it served me fine till two weeks back.
When I came home all the power was down because
the groundleak protection was triggerd.
Eventually it turned out to be the powersupply of this
hub that went bad on me. I want to replace it with
another psu but I can't find any info on the way
the ps2-like powerplug is wired.
The 810M needs +5V +12V -12V 0V and ground
connections.
Does anyone, familiar with this device, have a clue ???

Reset for the approach I took was simple...clear the ucode latchs.
the reset(restart) addres in ucode was 000h.

IRQ was simple too.. the first microinstruction for the normal
machine cycle was opcode fetch... unless the IRQ FF was set then
the microaddress loaded was interrupt action address rather than the
mapped opcode. That meant the interrupt system was synchronized
to instruction fetch and also the actions taken were what ever ucode
dictated. IRQ and CALL were the same basic ucode obviously.
Other things I played with is a JSR (pdp-8 style) and CALL(stack
style like z80 and others). Both had advantages but the JSR style
was easier to make fast in ucode{fewer microwords}.

At the time I did it (1981ish) the emulator would have to run on either CP/M
z80, RT-11(PDP-11) or my fingers. Part of the opcode thing was design,
test, then play what if. At that time I used 350ns 2732s as I had them
and could easily burn them, not fast but, easy to use. Also all the ucode
for lack of a compiler was hand written.
The approach was modular, simple and as much of the circuits repetitive
to make wiring (wire wrap) easy to do and troubleshoot. For example the
microstate machine was tested with one 2732, one LS273, one 74153 and
a debounced pushbutton. That allowed me to investigate things like micro
jumps, looping and startup. From there it was pretty easy to add more bits
to control other logic like RAM, ALU and bus traffic latches.
Using 2901s with that microcontroller was a fairly simple, expandable and
managable machine of moderate speed by 1981 standards. Still it was
fairly large and ate power!
One for the experimental machines tried with that hardware was a 1802 like
register based cpu with 16 registers like 1802 but the ALU and data paths
were also 16bits. Even simple changes like that have interesting effects
on in instruction sets and addressing modes. For example the 1802 does
not have instructions for loading or storing the 16bit register content, you
have to move bytes through the Accumulator due to 8bit busses (even
internal).
Once you have a 16bit path other things make more sense(or less!).

Yes, this box is not quite old enough, but it is an AppleTalk &
LocalTalk Router. The protocols probably do classify as "Classic".
Anyway, Cayman.com doesn't have docs online anymore for this, and
I'm gonna try calling/e-mailing them right after this is sent.
Does anyone else have a user's guide, and/or reference guide for
this? So far Google is turning up only 'How-To' for setting it up. I'd like
to get my hans on the paper guides that shipped with it. At least a copy, or
something...

Since I have had some requests from dealers I went through my storage locker
and pulled out most of the rest of my DEC cards. The highlight seems to be
some complete core memory sets. There are a couple of Floating Point cards, a
GPIB, 11/02 & 11/23 CPUs and Drive controllers.
Please contact me off list at whoagiii(a)aol.com with offers or if you have
questions. I am traveling this week so it may take me a day or two to answer.

OK, Bill, you wanted a PCI-based RS/6000?
One of our clients is trading up to an H80, and IBM just lowballed them
on their trade-in. They're putting thei old server on the market. It
ain't a classic or even uncommon, but I thought some of you guys might
be interested.
S70A 4-way
4G RAM
SSA - just adapters, they're keeping the drawer.
8 ethernet adapters, IIRC. 2 10/100, 6 10bT, subject to my CRAFT
Syndrome
PCI graphics, I think GXT120.
They're looking at about a $10,000 price tag, and a March 1 release
date. This guy has been lovingly & lavishly maintained.
Anybody interested can contact me for detailed specs.

Just found out yesterday that he doesn't have it anymore. No further
info. I asked if it was sold or scrapped or what, but my contact had
no idea. This guy would have gotten it from CompuServe circa 1994,
so I don't even know if he got rid of it recently or not.
Foo!

P.S. - Still working on the SC-35s and SC-40s. *No* idea if I'll ever
be able to get one as they drop off service eventually. There are
still several dozen in active use in Columbus.

Columbus, OH, home of CompuServe. Unfortunately, as I've already
written, I found out yesterday that at some point between 1994 and
last week, this guy got rid of it in an unspecified manner. :-(

I aquired an Apple Scribe printer last night (went back to the Thrift
Store and they hadn't repriced it, so I asked, and the guy let me have it
for $2).
It worked briefly, it printed the first 4 lines of a test pattern and
then jammed.
It looks like it may just need to be greased (the print carriage is
really hard to slide by hand, but not so hard that I am hitting motor
resistance, I just think after all these years, the guide bar may have
dried up enough).
But, before I get into opening it and regreasing it... I was seeing if
anyone had a manual for it and can tell me what the blinking light
indicates. When I turn it on, the Select Light blinks in patterns of
three (three blinks, pause, three blinks, pause...).
I did a quick google search, didn't turn up much (but found some places
to buy a new ribbon, and found a few "museum" listings for it). Apple's
TIL also didn't cover the lights (but has some control info so I can see
if I can get it to work with one of my computers).
Finally, does anyone know if there was ever a Mac driver for it? Or if
the Imagewriter driver will work with it? Apple's TIL seemed to indicate
it was just for the Apple II series (they leaned towards talking about
the IIc in conjunction with it, but since everything seemed to say the
application in use is what drives it, I would think just about any Apple
II with a serial card should be able to work with it).
I do know the archives showed someone else on the list found one of these
back in June, but there wasn't much said about it.
TIA
