Logic design with realys have different implmentations as a bistable with

I've used realy logic for machine control, operating speed 2 to 5 sec per
interation so fast was not a required thing. Doing sequential work using
relays and switches is really fun. Of course all that drove air valves
so there was air logic too. ;) Oh, and you can do logic with air valves,
air one shots, even flipflops.
Well, I've never seen one. Then again, I've never seen your ass.

My visit to the MIT Flea today was unproductive. But, so it wouldn't
be wasted, I grabbed a Sun 3/50 for $1. It seems to work, and is in
good condition. I looked at the board, it has a 68020. Can someone
tell me more? Also, how do I hook it up to a terminal? Which pins do
I need? I plugged my Mac in, but it didn't show anything. My Mac
serial cable only has pins 2,3,6,7,8, and 21.

I'd have to say probably not. I have a pair of HP-85s that I snagged in the
last 18 months. One cost me $1.00
at a private school flea market and the other cost $12.50 at an auction run
by Goodwill. The system from Goodwill
included an HP padded travel case -- in fact, the system was originally
stacked with some luggage and had not been
bought during that portion of the auction. I found out after I pointed the
system out to the auctioneer and bought it when
they auctioned off the rest of the computer stuff (usually C64s, Atari, and
the occasional Apple IIc or Mac Plus) that I
could have simple asked for a "no bid" sale for the last bid price in the
luggage area and gotten the system for $3.50.

Although I've participated in "auctions" of this type, I haven't gotten
shanked by another bidder. I can see how easy the private auction process
can be abused. I sometimes find myself doubtful of the bid increments that
I've seen; too easy to fake interest to inflate the price.

My suggestion to everybody is to put up your own classiccmp page, and
make sure you include the words "classic computer" so it can be found

rescue old machines, include the words "classic computer rescue squad",
and include your interests, geographical area, and contact info.
At one point, I was extremely tempted to put up some "official" web

The data sheet for the Motorola 6883 Synchronous Address Multiplexor,
which is the key wonder-chip in the CoCo 1 and 2, includes a schematic
that accounts for about 80% of the CoCo design. The 6883 and 6847 were
clearly designed to be used together, and the rest of the design was
pretty much driven by that. Of course, the CoCo does have a little
stuff hanging off of the two PIA's that isn't given in that data sheet.
But I'd be surprised if they had gone to Commodore for that.
Of course, I'm surprised enough at the patent on the case (who would
need to infringe a patent to make a rectanguloid plastic box?!), so I
guess the origin of the remainder of the circuit design could surprise
me too...

Ok, the 2002 wouldn't be exactly the machine for continous
display in action, but even if it is just as static display,
this one time running test ist the best verification that the
static display is _complete_.
(In fact, the critical part of the 2002 is the storage drum -
even back in time when it was new, every power up and down
had to be guarded by tecnicans - hmm but even here, since
the drum is a closed device, one could replace it (invisible)
by a modern electronic emulation... just thinking)

Nice - I could offer 9 hole paper tape over a (modified)
T100 Teletype on my Kim - before that I used paper and
pencile until the program was 'finished' and than an PROM

<Yes, relays are a lot slower than electronic devices, and yes, they may

They are reliable, especially the sealed ones...saves extracting
bugs(moths) with tweezers(aka: Lt Hopper).
Speed; the problem is cascade. I've worked with relay trees of good size
and while each can do 10s of repetitions persecond tens of them in cascade
can only complete one cycle in a second. To do logic like a counter
using relays is slow even though the individual relays may be fairly
fast. Though using s stepper relay is faster than chained relays.

I still like sBay an similar systems. At least they secure the
process a bit - like in an ordinary auction. And auctions are,
for shure, no place for rare or most wanted items. Not VL and
not RL. But they are a good thing to get fair prices for some
unusual or common things. I bought some rare spare parts via
eBay for just cents (and a brand new never opened never used
complete Mac IIsi for less than 100 USD :). But the best hits
are always on ordinary swap markets (flea markets) (like today
*g*) - even electronic swaps tend to have high prices.

Woooooosh - Your 'record' machine was just bypassed by
a 1941 Zuse build from junk telephone relais.
According to Zuse a multiplication took 3 seconds. A
Multiply nedded 16 Machine cycls and 16/3 equals to
5.33 Hz - just - 5 times faster - calculated on cycles,
but one cyle had 5 stages. Satge 1 to 3 where used for
execution, while 4 and 5 are used for load and fetch -
the operation fetch ocuresd simultaniously to the store.
So even this early had paralell working units (didn't
tried Intel to tell us that this was one of the big
inventions of the Pentium - you know the processor with
all the little rainbow coloured man inside instead of
the usual LGM)
Althrough the speed was something like 5 or 6 Hz, it
is legal to speak about a clock speed of 15 to 18 Hz
when comparing to newer machines.
And for relay speed itself - 40 to 100 (controlled)
switchings per second have been possible for pre war
relais and EMS relais (technique of the 60s) are able
to do up to 1500 Hz - we tried it 20 years back :)

Sorry about the white space, I'm using Lynx, as always...
I agree with that! I've taken two sets of disks for Mac System 7 from
a Mac Lab, and both had bad disks. OTOH, the 6.0.4 disks still work
fine, probably because of the lower density. Sometimes I wonder if
there's something wrong w/my drives, but they can read data written
by other drives...

My first exposure to storage was 5.25" disks in third grade for the
Apple ][. It was old then. We were being terrorized by a moron who
spent a month telling us to put disks into a sleeve. I wondered if
he knew to do anything else. BTW, can a disk be damaged if taken out
while it is being read from? That was a sin I had commited...
