Hi,
AFIK there is no substitute for the Lisa keyboard. However I'm told that
the mouse used on the early Macs will work on the Lisa. I think the plug on
the Lisa mouse has some plastic pins that are missing on the Mac mouse and
the plus has a slightly different shape.

Just recently IBM anounced their new series of (real) mainframes.
now called zServer(running zOS and zWhatever). They are supposed
to be the follow up architecture of the /390 ISA and will add 64
Bit Software to the /390 world ... And here comes my problem: I
can't imagine any way to enhance the /370 (/390) ISA to do such
tricks at all without loosing compatibility. It would require a
complete new 'mode', almost like Intel had with 16 vs 32 Bit on
the 80386, Mode switching an tons of incompatibilities - it took
almost 20 years to move the mainframe world from 24 to 31 Bit
addressing (and 24 Bit mode is still required for some apps and
modules) - and we are talking just about the valid bits of an
address word (allwas 32 Bit since the 60s) - introducing new
operations and data formats (or at least the usage of known but
rarely supported double word size registers) is quite a different
task.
So what I'm searchin are informations about the new ISA.
Any info is apreciated. And yes, I tried to ask IBM, (last
attempt today in persona at their 'booth' at the SYSTEMS)
but there is no info available.
I know this is off topic, since the z900 isn't even for sale
by now, but getting information is not only hard becaus IBM
doen't offer it, but because the people who know what a /370
ISA is are vanishing .... so any help is apreciated.
Gruss

Thanks everyone who sent me offers and information on the computer. I
think it will be destined for sale on eBay where I can let the market
set the price..... the offers were so far ranging that I feel that it
would be the best way to sell it and a search revealed three others
that had sold there recently. I'll include a copy of email I sent to
several who were interested in it's actual condition after I had a
chance to look it over. I brought it home last night and checked it
all over as mentioned below. I hope to have it placed on eBay this
weekend unless I break down and sell it to a reasonable offer off the
net or at a ham/computer fest I'm attending on Sunday. There is a pic
of the computer at http://www.vbe.com/~badger/bc/ec1a.jpg
Again..... thanks for your interest and all the information. de Mike

Last night I took the EC-1 and the other instruments I purchased at
the surplus sale home. I cleaned up the EC-1 and checked the tubes,
caps and all the circuits. I applied a little Caig Deoxit and with a
bit of time and care and was able to free up all the potentiometers
that were stiff or frozen. It appears to have been a factory built
version that was sold to the college...... very nicely built and laid
out.
The cabinet has a few small scratches... easily touched up... no dings
or dents. The rubber feet are still in place on the bottom. Inside,
while quite dusty when I received it has been cleaned up and is very
nice. Tubes and Caps and all wiring and pots check out fine. After
checking things over it went onto my isolated variac and was slowly
powered up..... lit up fine, adjusted B+ voltage.. was still right on
the money. Used the manual to set it up and adjust the individual amp
balance, all three ranges on each amp (100,10,1) balanced just fine.
Everything seems to work and adjust properly at this time so I assume
it's quite usable. The manual I have for it is an operation
manual..... apparently there is a construction manual that would have
come with it if it was a kit version as well. Also has three of those
little clear plugin units with a cap and a precision resistor....

You mentioned safetey interlocks...Maybe there's a panel interlock
that got jiggled during the move? Try removing and re-seating every
outside panel that you can find.
Have you tried connecting a console terminal to it yet? This may be
way off (I don't know anything about S36 hardware) but an acquaintance
of mine once beat his head against a wall for two days trying to power
up a VAX 8700. As it turns out, you do this by typing a command on
the console processor (a DEC Pro machine) which he hadn't connected
yet.
And...remember the "power-off" command in newer Sun OBP ROMs? A
favorite joke around here is 'why can't I type "power-on" to turn it
back on!!' ...but on newer Alpha machines (DS10, etc), you *CAN*.
There's a PIC17C44 processor in there handling console operations that
has its own little power supply. You can power-cycle the meat of the
machine from a [potentially remote] console port.

What I asked for I got...... an estimate of its worth. I did not say
that I
was accepting bids.... they just came in.... If I had stated that I'd
sell it
to the high bidder I would have, but that's not what I asked for.....
what I did
receive is a number of very informative posts with value estimates and
suggestions for places to offer it for sale..... eBay was the most
suggested
venue. I really don't care how it sells or if it sells..... it's just
"surplus"
to me. I'm not into collecting computers..... now if it were
electronic test
equipment or communications gear that's another story.
>From my perspective I was asking for help in assaying the value of
this piece I wanted to sell. I do appreciate the offers to purchase
(most) and especially those persons that sent me information on the
EC-1 and warned me that I might receive low ball offers from my post.
Some were... and had I not received replies from several very helpful
individuals I'd probably provided someone with real "steal" . I didn't
send angry email to those who made an offer that some would (not I)
perceive as trying to take advantage of my ignorance. In retrospect
after looking at the title of my post it should have said "Value of
EC-1 wanted"..... sorry if this was confusing. If you are still
bitching about selling it to the one making the best offer..... go to
eBay and bid along with those who may know it's value. At any rate
the your generous offer of $100 was far from the highest I received.

All of these puns concerning mental DECay made me think of a post I
saw on COMP.SYS.TANDY last week. Excuse the length, but I thought
some of you might find it amusing.

Power Computing PowerCurve, 400mhz G3, Mac OS 9.0.4
Collector of Classic Microcomputers and Video Game Systems:
http://www.geocities.com/siliconvalley/lakes/6757
I'm on the lookout for a couple of VAX items:
VAX 4000/90 (preferred) or a VAX 4000/60
KA68x or a KA69x CPU to round out the "house of VAX"
I've got a couple of VAXes I could trade if someone was looking to round
out their VAX collection:
MicroVAX II (BA23 or BA123 cabinet)
VAXStation 3100/M76 in a BA42 type cabinet
Various vaxish Q-bus boards.
PDP-11/03 board set. (KDF11, DRJ11, etc)
I'm always interested in things for PDP-8's, but high on my wishlist are
the cable for an RK8E to the RK05, a couple of RK05 packs (one with OS/8 on
it would be dandy :-) and those pesky top connectors that connect core
stacks, CPUs, etc.
In the PDP-11 space anything to add mass storage to my PDP-11/34 like an
RK11-D or RL11 interface.
Also available for trading: a CompuPro Z80 CPU (S100) manual and perhaps
the "Inside CP/M" and Garetz S-100 bus books ae well.

This is the "Magic / More Magic" switch. Leave the switch in the

LOL. It did remind me of that story. :)
If there's anyone on this list who doesn't know that tale, ask for a retelling. It's good.

Right. I have an 8300, dual 8200 CPUs.

My 8300 is on one 30A Hubbel twist-n-loc I installed in my basement. It
powers the CPU, a single RA81 and an MBA ESDI-to-SDI box (2.1Gb). I always
power on the RA81 *first*, then let it settle, before firing up the other
boxes (due to the surge current of the RA81 HDA).
Fun little box. Watch out for the KDB50 - I never met one that wasn't
finiky.
