While surfing the Unisys websight, I found nearly NO mention of either
Burroughs or Univac.
One more reason to like IBM.

Hello fellow ClassicCmp'ers,
This is almost Classic - I'm looking for a place to download an old
version of FreeBSD, specifically the last release of the 2.2.x branch,
which I think was 2.2.8. However, it seems to have totally vanished off
the net, including of course ftp.FreeBSD.ORG, apparently removed by the
dark forces of the evil reptilian conspiracy who want to force everyone
to run the modern crap. Has anyone saved a copy of the FreeBSD 2.2.8
distribution or some nearby version? TIA,
MS

I'd agree.
I off in its place MACROASSEMBLER, which is fairly old, very flexible
and portable. That and a good macro library you too can have something
looking almost like C or pseudocode if thats your wish.
The only problem is I doubt there many that still know it or use it.
I think them small chips that run chevy fuel injection are programmed
in C++ crosscompiled, or so they would have us believe. ;)

My Silent 700 has decided to stop working. Some of the time. It
won't print anything although it will move the printhead for CR,
LF (but not space or any other printing character) and will sound
the beeper from Ctrl-G (BEL). The keyboard is outputting all
characters properly.
I took it apart (easy since almost everything snaps in place),
checked the power supply voltages which all seem reasonable,
noticed it was working, put the case back on, now it's broke
again. Aargh. Must be a cold solder joint somewhere but there's
LOTS of parts inside that small case including an 8080 CPU. I
removed the three socketed chips and reinserted. Then I
incautiously got a finger on either 120VAC or rectified 150 VDC,
in an area I was not expecting "hot" voltages.
=8^0
At that point I decided not to play with it any more, at least
without a schematic. Anyone got one, or a service manual? I can't
locate anything online from Googling.
thanks

... like the subject line says.
Now that my 8/A is up and running it's time to hook up the RL02. I
do have the interface board plugged into the Omnibus, the correct
boot ROMs on the option board, and the RL02 has the Unit "0" plug
but no cable or terminator. I could make my own if someone can
tell me where to get the connectors that fit the drive end.
Also, I think someone cannibalized the disk brush out of mine :(
There is a big open area towards the right rear of the disk
compartment and a pin with a snapring groove protruding downwards,
but nothing in the empty hole there except two silver-colored
tubes down below (air ducts?)... seemed pretty clean inside, as it
should.
So I left the heads parked (blocked by the transport plate),
inserted the disk pack and ran the blower for a while anyway.
Fault light was on, load light was not. I didn't hook it up to the
interface board (obviously :) but not being well-acquainted with
these drives I don't know if it *has* to be connected before the
fault light goes off, or the heads free to load, or both...
I do have a copy of the "RL01/02 Disk Subsystem User's Manual" but
the service manual and parts list looks essential at this point.
Hope it's on bitsavers ;)
Thanks for any help.

Extinct due to envromental concerns. Common use these days are the
3V lithium coin cells for the same uses.

Do not attempt to charge. Bad things can happen.
Mercury batteries were used for many reasons, high energy density,
extremely long shelf life at near zero power consumption and very
stable voltage over life. Lithium cells have replaced them in
most apps where battey drain is low and extremely long stable
life is desired.

I'd expect that would work just fine. If your really uncertain add a shotkey
rectifer in series (Vf about .3V). My bet is the logic they keep alive
is a CMOS RAM and in operation that device Vcc is 5V.

I think I have a few of the RL02 cables that have the funny ends. But I only have one of the ribbon cable that goes from the inerface card with a berg connector to the bulk head. I am sure I could scrounge one of those spares if you don't get one elsewhere. I only have one
good working RL02 drive, but many parts drives.

Actually all 9133V and 9133XV should have the same controller (09133-69508)
at least that's what the book says:
http://bitsavers.org/pdf/hp/disc/09134-90032-Aug-1983.pdf
page III-1-2 (9133V/XV & 9134XV Theory of Operation).
Regarding the jumper settings for selecting between 4 volume (HP-85
compatible) vs 1 volume configurations, Section II of the manual which
refers to the 9133A/B, 9134A/B and the 9135 drives, shows the J6 jumper
settings on page II-1-9 [1], while Section III has a table on page III-1-1.
BTW this manual provides a wealth of information about all the Amigo
compatible members of the 913X family. It is beautifully scanned in B&W
(pictures in greyscale) and produces high-quality printed output.
If you have an early version 913X, this manual is a must-have.
**vp
[1] early versions of the 9133A, 9134A and 9135A drives used a different
controller which does not appear to be configurable (see page II-1-2).

RL01 and RL02 cables have those funny connectors at both ends. It
sounds like you haven't got the ribbon cable for the interface end
either; that would be a short 40-way ribbon with a Berg connector on
each end with one of the opposite-gender funny RL0x connectors plugged
into one of the Bergs.
I've never seen those connectors elsewhere, but on the inside of the
drive, they're 40-pin headers like a Berg connector, so you could, as a
last resort, use something else to get you going.
> Also, I think someone cannibalized the disk brush out of mine :(
No, only early RL01s had brushes. There's a field change order to
remove them, and AFAIR RL02s never had brushes at all.

It has to be connected and terminated before the fault light will go
off.

Look for the Pocket Service Guide -- that will give you what you need.

I took the IRIS over to Ray's to see if we could get it working and pull anything of interest off the drives, and the power supply died. If you have one of the Motorola IRISes be sure that you check out two paper caps (C7 is one of them) on the 5v rail board (on the fan side of the P/S). Had a failure in one or both that caused a (hypothesized) spike to the rectifier bridge and smoked a MOV/resistor link to ground. Fortunately there doesn't seem to be any logic damage, but watch out if you've got one of these!
Later research with an electronics book revealed that paper & electrolytic are the most failure-prone of the capacitors. I'm going to replace with mylar (I know they're not original, Tony, but it's a terrible job to get that P/S out, and I don't want anything to die the next time).
