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.

Not exactly, the SCSI port is only for a tape drive, a TK50Z (an early

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.

have lots of FAQs for uVAX 2000s. I don't know the URLs but if you post

check the old DEC scrap box. IIRC it brings one up to either 8 or 14MB

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.

ROM's might be possible, but a Robotron game gets a lot of heavy-duty

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.

I seem to remember that eBay offers private auctions -- you put something

might facilitate auctioning things off to list members.

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......
Cheers

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).
