The SLM804 Laser Printer was Tramiel's attempt at a laser-for-the-masses
back when a Laser Printer was a multi-thousand-dollar item. It had no
on-board intelligence or memory; it used the ST's CPU/RAM. Sounds like
what you have there is the controller interface. (Plugs into the ACSI port
on one end and the printer on the other.)
P.S., anyone want an SLM804 in need of some repair?

Hmm, IMSAI's didn't have ROMs (or PALs and FPGAs, programmable logic had
yet to be invented), unless you added them in yourself. As for checking
the power supply, an IMSAI was extremely easy to eyeball...huge
transformer, diodes, and beer can size capacitors. One problem I never
had with IMSAIs was in the power supply, the design was right out of
Electronics 101, nothing beats a big lump of iron for simplicity. Now
rust might be a problem...
Actually, the only real problem I've ever found with S-100s is the bus
connectors wearing out. I have an old Ithaca Intersystems DPS-1 in need
of a replacement Morrow motherboard. Well, not really in a hurry to fix
it, all the Ithaca boards have been in the IMSAI for the last 10 years,
but I hate to throw out the DPS-1 since it had the neat front panel with
the PDP style toggle switches.

The 25 pin is the TTA2 port, RS423 (close to RS232) with full modem

15 pin is for a workstation cable and carries the video (the coax
connector on the little box), plus a keyboard and mouse connector (TTA0:
and TTA1: serial ports). They are not RJ45s. You should also have a
BNC coax connector for 10Base5 thinwire ethernet.

I recently acquired a laptop that appears to be an NEC PC-8201 with a label
of a company named Intelus on the front where the PC-8201 label would be.
There is also a serial number label on the back that lists the address of
Intelus as in Rockville, Maryland. In addition, it has a miniature
connector labeled phone on the back in place of the second SIO connector
(maybe the unit has an internal modem? I haven't opened it up to check),
and it has an additional small removable panel on the back that provides
access to an edge-card connector on the motherboard. My machine has
nothing plugged into this connector. The machine fires up showing BASIC,
TELCOM, and TEXT programs in ROM, and the BASIC program even says PC-8201
Basic, verson 1.1. The machine is in all other respects (keyboard,
display, battery pack, ROM access, and external connectors) identical to my
PC-8201. Is anyone familiar with this machine?

Robotron is also a video game ca. 1981-2 (Williams, iirc) that was
semi-unique in that it used dual joysticks -- one to control movement and
one to control firing direction -- and in order to be at all successful at
the game one had to be able to operate the two completely independantly of
each other. Other, similar games included Sinistar (no relation, and don't
even go there) and one whose name I forgot that had to do with spiders and
webs.

Good point. Many early clocks were (or contained) primitive analogue
computers, so I think you win there... sort of.
Two books to look at: "The Mediaeval Machine" by J. Gimpel and "A
History of Engineering in Classical and Mediaeval Times" by D. R. Hill.
Gimpel will fill several holes in your timeline - Su Sung made quite a
complicated astronomical clock in c. 1090; the middle ages saw a
sizeable crop of similar machines in the west, culminating in that of
Giovanni Dondi, under development from 1348 until 1364.
Hill's treatment of clocks is also interesting. He points out that the
Classical civilisations had (presumably inherited from the ancients) a
system by which the hour changed in length depending on the date so that
sunrise to sunset was always twelve hours. Thus ordinary timekeeping
clocks had to combine time and date in an analogue computer to get
hour-number out at the end. Some of the mechanisms Hill describes get
this quite wrong! (I don't recall any of these clocks also taking
account of lattitude...)
OK. I'll go for the Z1 as the first _general purpose_ computer.
Philip.
Ok Atari-heads, what the hell is an SLMC804 Laser? It looks like some
sort of SCSI adapter. Its an external device the size of an external

at least, if you are really sure, you made the right connections, test &
check it again. the sdi cables are very picky, if you "made" a connection,
be sure to fasten the screws also. sometimes it doesn't work without fasten
it.

one more shot in the dark ;-))
the ra81 & ra82 have in diagnostic port on the disks. you can get more
information about the disks, if you put a terminal at it. But don't ask, i
never done it, (i got my disks to run without it) try DejaNews.
hope it helps a little,

One of the 'Power without the Price' products from ATARI.
basicly a 300 dpi Laser unit with only minimal control
logic (only a bit map buffer for one (?) line of graphic.
Connection to the ST computers where made via the ACSI port -
ATARIs castarated version of SCSI used for the ST Harddisk.
The whole font and page processing had to be done by the
host computer - but the Printer was availabel for less than
2000 Mark (~1300 USD) when new - only haf the price of the
cheapest 'regular' laser printer.

Hello List:::::
I am looking for one or two 'real' DEC 9 trk tape drives
w/formatter cards, in the SoCal area... TU16 and the like, and one
of the small 7" reel jobs whose model number escapes me just now. I
am willing to pay moderate sums for known-good-working units.
Also looking for a *complete* 11/750 system... (computer, drives,
tape unit, console, docs[ha!], etc.).
I have a very old 11/15 to sell/trade, and several Plessey clone
devices, including two CDC Caelus drives w/interface cards and
engineering docs.... I can deliver in the General SoCal area.
Note to Down Under Listmembers: I will be travelling to Sydney on
the 2nd of July, and then caravanning to Adelaide over the space of
about 10 days. It would be cool to meet some of my fellow collectors
while I'm in your quadrant of the globe. E-mail me privately if
there's any interest.... esp. Huw Davies, it would be fun to thank
you in person for the help with my RK05 odyssey... ;}
Driving: The farthest I've gone to 'rescue' PDP stuff was Los
Angeles to Seattle and back in three days... 2200 miles. It was
truly fun to be out on the Road away from work, phones, e-mail,
faxes, memos, interruptions... thanks again to Bruce Lane for
providing the excuse.. :o
Oh, yeah... anyone have a Kennedy 9300 cheap/trade/free? I need
some Parts......

Those are the ones I saw as well... he was asking $25 for a broken
one (but cosmetically pretty good) and $100 for the working ones.
If I remember correctly, they are essentially a BASIC computer with
printer and something similar to a TU58 drive.
It's just that I remember using one at WPI when I was there in the
70's and wanted to get one for my collection...

OK... I've got a MicroVAX II almost ready to go. However, I'm handicapped
by my lack of any documentation for the RA82 disk drive.
The problem: When spun up, even when connected to the KDA50 controller,
the drive gets up to speed, seeks a couple of times, and then lights 'Fault.'
I'll press the 'Fault' button to try and reset. On the first press,
'Run/Stop' and 'Write Protect' flash. On the second press, it goes through
its seek-and-fault cycle again.
My question: Do I even have the thing wired right? Could someone familiar
with this stuff describe to me which cable goes where, just to make sure
I'm not hallucinating?
The controller seems OK. It passes its internal and service diagnostics,
and when I stare at the LEDs on the two boards long enough I can see some
sort of fast scanning sequence going on about every 5-7 seconds.
I can, if need be, open up the RA82 and see which internal LEDs come up.
Any and all help appreciated. Thanks in advance.

"Our science can only describe an object, event, or living thing in our own
human terms. It cannot, in any way, define any of them..."
What a surprising day, went to the Stockton Delta College Flea Market (in
California) and found a couple goodies...
First I bought an SX-64 keyboard and C-128 in the $1.00 section of someones
space. I bought the SX keyboard cause I have a second (dead) SX without one
the 128 was because I felt sorry for them having to break a 20 (also I figured
if it was dead I could use its keyboard with that keyboardless 128D I have).
After wandering a bit my wife shows up with a keyboardless SX-64 also from the
same booth's dollar section, what a wonderful woman! (I must've missed that
SX, better have my eyes checked!).
Anyway $3.00 spent and get home to discover the 128 works (missing the F3
key) and the SX has some issues but seems functional (does not boot to BASIC,
just a black screen, but does run carts ok, probably bad BASIC/KERNEL ROMs
also keyboard connector/curcuitry needs work too.)
So far I have bought 3 128s (real cheap) with the plan to use the (supposed
dead 128's) keyboard on the D to discover it was not even a dead machine after
all. Well Sam, (who finds many a dead Commodore 8-bit) I guess Commodore
spirits aren't with you. :)
Almost was tempted to buy a few of someone else's Mac problems (nice seller,
he told the truth on all of em), but I figured I'd play it smart (this time).

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
easily through the search engines. Or, if you are volunteering to
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

both of the other two who did this have vanished without a trace.

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...

Oh, thats also the best description for the 'modern' displays

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
burner for archiving - superiour accestime :)

<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...
