Yes.
PDT150, low cost (then) PDP-11 running RT-11.
Robin, VT180 CPM system.
DECMATE series (wordprocessing with extensions)
Rainbow
PRO3xx
All pre-PC boom or leading into that time. Keep in mind that
the idea of home computer was a 1984-5ish or later event.
Before that marketing was more aimed at hobbiests(anything),
lowcost home systems(mostly gaming) and business systems
(packaged or extensible systems).
As a reference in 1985 a good business system was a
$5-7000 (USD) investment. It didn't make much difference
if it was PC, S100, Multibus or whatever. Around then things
we take for granted were not cheap. In 85 10-40mb of disk
with controller was ~$700, decent printer $400+ and so on.
For example in 1981 my NS* Horizon (z80 64k) with 5mb
hard disk, H19 terminal, Anadex printer was valued around
$3700! A PC with all the trimings to do the same task was
not cheaper.

There is that. My experience is the term "slew rate" commonly associated
with op-amps.
Now the common use, slew meaning a whole lot of them is more in the
realm of slang and something I am accustomed to.
So the juxtapostion of delta, large quantiry and also quagmire in that
statement was subtle good humor. Then again I enjoy Samual Clements
and his style of writing as well.

Eh? Perhaps American pronunciation differs, but over here "slough"
(meaning swamp) is pronounced to rhyme with "plough" ('plow') :-) Anyway,
"slew" means "large number or quantity" [Oxford English Dictionary], which
I'm sure is what Sean means... On the other hand, "slough" pronounced
"sluff" means dead tissue that drops off from living flesh. Given the
context...

I have done this on a 48T02 for my SPARC2. I did it at one end of the
chip and I cut *through* the leads going up to the battery to disconnect
it from the SRAM entirely. After I exposed the leads, I soldered on a
9V battery cable which I snapped onto a 9V battery top (removed from a
dead battery), into which I soldered a 3V lithium battery that had solder
leads already bonded to it (scavenged from a dead board of some kind).
I placed all the active bits in a small ziploc baggie for insulation and
closed up the case. I do have a replacement 48T02 on order ($15 from Mouser),
but for now, I'm running.

Exactly! That is why I said V1.0. finding a copy of 1.0 is the challenge.
There are other signatures. Check the bytes following all the RET
instructions. as there were some funnies there. Keep in mind you
have to look in the BDOS for all this as the BIOS is customer code
and the CCP is also modifyable. In DOS most of that is embedded
in the command.com.

See the excerpted comment from the earlier message.
The BA23 and BA123 differ in the number of Q/CD slots with the BA123
having more.

I'm looking for a good spot to call home for my classiccmp related web pages
(lotsa images&scans). I'd love to get it all under ARSDigitia ala
http://photo.net but last time I checked, it required a Sun/AOLServer/Oracle
trinity, so a few megabytes and a cool name will do... Oh yeah, free would
be nice too. ;)
Any suggestions?
Thanks

I don't *think* this is OT, I don't see any IC date codes newer than '89...
Is anyone here familiar with the inner workings of a Kennedy 9662 tape
drive? FWIW, I think the 9610/9612/9660/9662 are all essentially the same
drive, depending on the combination of {rack mount vs. table top} and {Pertec
vs. SCSI}.
My problem is, the drive keeps giving "TAK ARM?" errors, which according
to the manual, means there's some problem with the takeup arm (i.e. the
motor-driven arm which has the takeup pulley on it). I've been all through
the manual section on how to adjust the various relevant sensors and I *think*
I've got it more or less happy. I fiddled with the height of the capacitive
disk thingy (which evidently is what encodes the arm position for the on-board
micro), it was way off but now I'm getting more or less the voltage spread
that the manual asks for and the "zero" position does give 0.0V.
But I'm totally stuck with what to do next, partly because there are some
differences between my drive and what's in the manual. The manual claims
that there's a mechanical limit adjustment, but there's nothing in the
area where the arrow points (it's not even visible on their sketch so I
don't know what they mean here). The cam that drives the micro switch to
set the limit of arm travel is nothing like what's in the book, I've been
dinking with its set screw trying to move the limit one way or the other
but the same mechanism seems to be what drives the *actual* mechanical limit
(there's one peg which pushes another) and I don't seem to have independent
control over them -- maybe that's on purpose since the manual wants the
switch limit set a fixed angle past the mechanical limit (I would think
they'd want it the other way around though???).
Anyway I have no idea what to do next, is this familiar territory for any
of you folks? FWIW the drive gave the same message when I first got it, but
after I randomly poked and prodded around the takeup arm a bit it magically
started working. So of course I'm suspicious that the actual problem is just
a flakey connector or something (I've wiggled them all again) and not the
mechanical adjustment at all, although as I say the range that the encoder
was giving was all wrong. Unless it's actually my manual that's all wrong.
I'd really like to bring this thing back to live, it was a wonderful
tape drive.
Thanks,

Y'all may recall I wrote a couple weeks back about needing an NEC APC
to try to read these disks that a geophysicist sent me so Guatemala can
find all their precious resources.
Fast forward a few weeks: I spent an hour or so digging around my
warehouse and managed to locate and then extricate the NEC APC I
had. Tonight I finally got around to checking it out again (I got it over 4
years ago and when I played with it then I couldn't get anything to come
up on it). Well tonight I was fiddling with it and realized the brightness
knob was turned all the way down. It turns out this thing works after all!
The system came with 2 disks in the drives when I received it. One in
the A drive is labeled "SYS" and the other in the B drive something else,
it's not important, since the system is trying to boot from A.
When I first turn it on, the upper lefthand corner of the screen shows
"[LOD]" and the disk light comes on. Actually, there are two red LEDs
per drive. The bottom light is always on, and it seems when it's reading
a disk the top one turns on. It tries the A drive and then displays "[LOD
C]" and momentarily accesses the B drive. Then I get "[LER]".
So I need to know what this all means. I'm assuming that either the
disks are bad or the drive heads are dirty. Of course there may be
something worse going on but I'm an optimist (mostly).
So I could use the following if you've got it:
a) information from the system manuals that explain the boot process.
I've got the manuals but there is no way in hell I'd be able to find them
without a full-scale re-organization of my warehouse, which I hope to do
in my lifetime but definitely don't have the time for right now.
b) a known good copy of a system disk.
This is an NEC APC model APC-H02. The floppies are 8".
Any help will be greatly appreciated and if we are successful with getting
the data off you will be given credit for your assistance!! Remember,
goats and village women!
