Hi,
I have what could be called a classic machine, a Sun-1 (With a Sun-2
upgrade 68010 board) Now I have 1/2 and 1/4 inch tape drives 2 hard drives
loads of tapes/manuals and a SunOS 3.2 boot tape set. This machine was
only recently taken out of service after it spend some years converting
old 1/2" tapes into a more permanent format. The HDD's are unfortunatly
dying and I've only had it booted once, and it booted SunOS 3.2. The
problem is the old machine refuses to boot of it's tape drive (an archive
QIC-11 drive) typing:
> b ar()
simply gets
ar: 96A0 Error
Retensing...
ar: 90C8 Error
>
Network booting is possible, but Sun never released the specs to the "nd"
network protocol and I don't have access to another SunOS box to try and
work out how ndbootd works.
I'd love to get this machine working and up on the net.
Any help would be appreciated
Karl

If it has ISA bus either JADE, JAMCO or JDR I forget which, sells an
ISA-8 bit to standard IDE adaptor. What makes it nice is it has bios
support on it. Acculogic made one too at lone time.

The Z-67 is a rare item indeed. I missed one in 1988. That's the last time
I ever saw one offered for sale (and it was *just the interface*). I don't
know anybody running one of these . . .
My Z-89 dosen't run anymore. Too many years of disuse, I guess.

Hi All:
I'm hoping someone might have spare copies of DR PL/I-86 (CPM86)
documents (Reference Manual & Programmer's Manual).
I have some good IBM docs but I need platform specific.
I don't think I need any 3rd part PL/I manuals yet, but if anyone has
some and would like to email the list to me, I'll certainly browse with
intent to buy.
I'm willing to pay a reasonable proce plus shipping, of course, for any
books.
I'm also looking for original PL/I programs for microcomputer platforms
if anyone has some collecting dust.
Thanks,
Mike Allison

I just got an Amstrad ppc 640, and am starting to realise how much I really
wish this thing had a hard disk - even a little one. Is there ANY sort of
hard disk solution that will plug into a 720k 3.5inch floppy controller?
Ideally it would come out the other end in IDE, and I could put one of those
little 1.8 inch 20 meg IDE drives in the thing. Speed is not a huge concern,
since this is a 4.77mhz XT class machine.
Also, if anyone has a wrecked ppc 512 or 640 that has a good back case section-
the bottom part of the main body that the handle is screwed to (and the handle)
I'd be very interested in buying it. Mine appears to have gotten squooshed in
shipping and had the handle torn off, and I'm lothe to trust epoxied plastic
to hold a 14+ pound computer.

Weelll, I can't lurk on this one.
Zane, is your record from Norlin Company? If so, it is the (quite
rare) demo record that Norlin put out when they bought Moog music
>from Bob (Moog). I have archived several of these demos, Moog and
ARP and Oberhiem. Be careful if you play it, they weren't on the
best vinyl.
Zane and Bruce: The Moog Modular Synths were just that... a
collection of modules of various kinds that one ordered to assemble
a complete system... kinda like DEC stuff. There were standard
configs available, but you could add-on, mix-match, whatever.
The particular instrument I am priveleged to share my studio with
is a Model 55 IIIC+ , and was owned by the late Paul Beaver, who used
it to make most of the strange sound effects for a small, obscure
movie in the late 70s called "Star Wars" or something like that.
More detail on them can be found by doing a websearch on "musical
instruments, electronic, Moog"... or one can got to
www.synthfool.com for a good set of links.
ObCLASSICCMP: One of my intentions for at least one of my PDP11
systems is to interface it to my Moog, and obtain an old copy of
Csound or the like.. to recreate an exact environment from the
'childhood' of electronic music.
My collection and studio: www.lightsound.org. The site needs
updating, but you can see the specs for several classic synththesizers.

ps: Kennedy 9300 parts / svc manual wanted... Enquire Within.
A few questions about clean(ing) circuits:
a)Can dust cause any damage to a PCB? Can it short anything?
b)What do you recommend for cleaning out PCBs if there's lot of it,
or spiderwebs, mold whatever?
c)Does distilled water cause rust?
d)Can distilled water be used to clean circuits?
e)As I understand, tap/spring/rain/etc. water is full of minerals
and that's why it's conductive as well as rust-causing
f)A while ago, I picked up a bunch of 5.25" diskettes, which I hardly
allowed to dry before I put them into the plastic box. Now I
looked inside, and mold is spreading from the Microsoft Assembler
diskettes onto the Apple II ones. What is safe to use to clean
the mold (it's reeely disgusting!)?

This is true. All signals on the bus and off it obey Transmission line
theory. IT's also the one of the reasons why the T-connector for thin
eithernet must be on the back of the machine and not a 3ft jumper away.
One of the design rules that ALtair bused the worst and IMSAI seemed to
have a clue on was what are clalled stubs. What this translates to
is anything going onto and off of the backplane(bus) MUST be buffered
as close to the edge connector as possible.

No it didn't and doesn't need it. They approached it a bit different
by making one end of the bus a permanently resident IO section with
seria, parallel and heartbeat interrupt. Their choice of drivers and
recievers helped some too. Obeying stub theory was another step taken.
It is good enough that even at 8mhz z80 it works.
< was made worse by use of the long wires that ran from the MB to the fron

that was the horror I saw when I built my altair back when. As an

proved to be true. The solution was a small board that plugged in and
buffered all the signals to and from the front pannel.

SCSI is an open collector bus so you need both termination (any) and
it must pull up unused lines or it don't work. This is also true for DEC
Omnibus, Unibus and Qbusses.
One of the long standing problems with bus terminations is that they
absorb power. This required stiffer drivers at the source and since
stiffer drivers matched the bus impedence even worse it tended to make
problem grow rather than solve it. it also consumes power contributing
heat to the box. S100 bus was one of those we made it that way but, no
one ever would have engineered it that way. All of the engineered buses
are terminated in some way or designed to perform without the need for it.

For once, I used the correct terminology :) Compared to SCSI, all
IDE controllers and most non-IDE/SCSI MFM drives require very little
configuration. That's what I meant.

So does this mean 1.2MB floppies use a lower bps than 360K disks?

Where can the connectors be gotten cheaply? I've seen them for a

Yes, there it is. "CAUTION! Indoor use only. To be used only with IBM

I just acquired two Apple prototype keyboards. The keyboard is very
small with no frame and only 58 keys. They hvae stereo-type connectors
on them, as oppose to ADB, and I have an adapter box to hook them up to a
Mac Plus (and they do work, btw).
According to my "AppleDesign" book, they are "Cassie" keyboards,
co-designed by Mannock and Esslinger for the SnowWhite Project. Does
anyone have any further information on these keyboards? And how do
things like this get outside of Apple? I'm under the impression Apple
doesn't exactly give this kind of stuff away.
On the back the keyboards read:
[logo]apple
apq
Development Engineering
PROTOTYPE
S/n# Model#
1012
(the other says "1032")
Does Apple start numbering at '1' or '1000'?
The keyboard, btw, is obviously a prototype. The whole thing seems quite
flimsy and the keys are all angled slightly differently.

It's mostly a problem if there isn't documentation at the place where
the machine is. I've never run into a machine that is really beyond my
experience (my experience so far is PCs and BASIC-based home micros),
but if I ever had to deal with a PDP, I'd have to spend a lot of time
asking questions here and otherwise. Not that I foresee it. PDP will
eventually vanish from industrial applications, just because they will
all eventually be damaged by floods, fires, etc. And companies go
bankrupt, too. I doubt that by the time I am 50 I will run a reasonable
risk of seeing a PDP. Also, I don't know how to _program_ a PC. I know a
bit of BASIC (who doesn't?), enough to write a simple text editor or
something. I'm learning C but am stuck with pointers. I'm going to take
C++ at school starting in the fall. I've tried assembly, and do notice
that it's more straightforward than higher-level languages (I.E. there
are no ambiguous concepts like in C, it's all called what it really is),
but am not much good with
things mathematical. Maybe I'll learn.
