The Index Mark is a single small block of data recorded on the disk,
that occurs once per track, right after the index hole; it's NOT the
index pulse from the hardware, and NOT a sector header and it is
optional. Lots of controllers don't put it there unless told to.
Given that any sensible controller will see the index pulse from the
drive interface, the Index Mark pattern is unneccessary -- but some
controllers do expect to see it.

Back in October of 1998 there was a new video game magazine called fuse that
was shipped on VHS tapes and was billed as "The Video Game Magazine of the
Future". I just found "Issue 1 Volume 1 Nov/Dec 1998" over in my bus but it
was missing a bonus promotional copy of fuse in the box. Does anyone have
this bonus issue? I did a google and could not find anything on the magazine
I guess they didn't last very long.
I've just run across a partially-working Heath ID-5001 and am trying to get
it do something useful. At the very least, the flourescent bulb PSU is
out (the TIP41 gets *really* hot in a couple of minutes), and the front
bezel has some cracks. The rest of the unit looks fine, though.
With the top off, and room light shining in, it's possible to read the
display. I can set the baud rate and the date/time from the front panel,
but not much else.
I've already run across an LED back-light scheme, so in the long-run, I can
fix that. I've also seen a page on how to manufacture temperature sensors
with non-obsolete parts. I could really use some docs on how to calibrate
the unit (there are several pots on the CPU board), and how the other sensors
work.
Anyone on the list have one of these?

Anyone out here ever have or currently have a PCjr with the RIM Adapter setup? I have 2 types of modem-slotted SCSI cards, onne being from Rim Electronics, and the other from an unknown maker. I have HardBIOSjr cartridge, the ST-225 HDD's for the Rim Electronics SCSI card, but am unable to get jr to recognize them. Any ideas from someone who used this setup before?

Google a bit it only took 2 attempts for this one.
Device was known as pc-lock, you apparrently have the first model
pc lock II is much better put together.
Before I take a few things apart to use for spare chips, power
supplies, screws, nuts, wires, etc., I'll ask: are there any
collectors of NCR minicomputer/multiprocessor equipment on this list?
If so, I'll go grab some part numbers.
One box, about three feet long, about a foot and a half wide, and about
three inches high, is some sort of SMD controller (sorry, I'm keeping
the 9" CDC hard drive, unless someone wants to swap reasonably
equivalent drives in case this may have some useful OS software,
etc. on it).
The other box appears to be a processor that was part of some
multi-processor system. Again, similar dimensions, except for it
being about 7 inches thick.
Price negotiable. Local pick-up only, but I may reconsider if someone
has something interesting to trade. :-) Don't wait too long, a blue
flame is waiting to be applied to the back of the circuit boards so
that I can retrieve some useful chips, re-use the power supplies (or
components thereof) and use the cases for other projects.

The single-density "DFS" format is particularly easy. It consists of
10 sectors of 256 bytes per track, numbered 0 to 9, and is nominally
single-sided. If you have doubled-sided drives, side 0 of the first
drive is referred to as drive 0, and the sector headers are just as
you'd expect; the second side (side 1) is referred to as drive 2, and
has the *same* sector headers (ie the "head" number is stored in the
header as "0", not "1"). Drives can be either 40-track or 80-track;
the only difference (apart from the number of tracks, obviously) is the
size stored in the directory. Recording method is standard FM with an
Index Mark. There's no sector-to-sector interleave on a track, but the
start of each track is skewed by three sectors, compared to the
previous one.
The directory occupies the first two sectors of track 0, and is
extremely simple. I can describe it if you like, or give you a 512-byte
dump of the two sectors.
The double-density "ADFS" format is a bit more complicated. There are
several variations, but the BBC Micro (as opposed to the later
Archimedes) supported "S" (small) format (40 track SS), "M" (medium)
(40 track DS or 80 track SS), and "L" (80 track DS). The DS versions
are a little unusual in that they use all of side 0 before using any of
side 1, but the head numbers are what you'd expect (ie "0" for side 0
and "1" for side 1). Each track is 16 sectors of 256 bytes, numbered
0-15, no interleave, track-to-track skew of 9 (ie track one begins with
sector 9, track 1 begins with 2, track 2 with 11, etc), standard MFM
but normally *without* an Index Mark (though it shouldn't matter if you
put one in).
The directory's a bit more complicated becasue there's a proper free
space map, and it's a hierarchical structure.

Hi,
I was cleaning my office as I prepare to retire, and found several DECtapes
with programs I wrote for a PDP-9 in the mid 70's. I have no listings
available, but would like to read these programs if possible. I did a
Google search for DECtape, and came up with a posting you did Sep 4, 2002 on
getting a DECtape running. I was wondering if you have any pointers on
where I might get these tapes read? They would be written for 18-bit pdp-9,
but if I could get the images in any way I think I might be able to figure
out how to combine the blocks and translate the bit patterns to ascii.
Thanks in advance for any pointers. I have lost contact long ago with my
pdp9's and pdp11's.

In the data sheet, under the section "1. Non-IBM Formats" it says:
"Note that the Index Mark is not required by the 179X."
What does this mean exactly? How can a track contain any useful
imformation without a Index Mark?
Here is the whole paragraph for reference:
Variations in the IBM format are possible to a limited extent if the
following requirements are met: sector size must be a choice of 128,
256, 512, or 1024 bytes; gap sizes must be according to the following
table. Note that the Index Mark is not required by the 179X. The minimum
gap sizes shown are that which is required by the 179X, with PLL lock-up
time, motor speed variation, etc., adding additional bytes.

Hi everyone,

Just wanted to share this with you - Santa dropped off a very cool
version of the Motorola 6800 MEK6800D2 trainer yesterday. The system was
installed in a custom-fitted case for use in a System Design course
taught at the University of Waterloo (Ontario,Canada), home of WATFOR
and WATFIV. There is a remote LED display relocated to the "dashboard"
area above the keyboard and a power supply is built in. Cassette and
expansion interfaces are brought out very neatly to the rear panel.
I don't know when this system was encased, but it could have actually
predated the SOL-20! I have no idea if the Hamilton Enclosure people
knew of Processor Tech or vice versa - maybe it was just a common
interest in Danish Modern design? Anyone have any more info?

I thought there might be a few folks on the list who might be interested
in these. I spoke with the owner of the manuals back in early October
after he sold the system these went with, and the buyer didn't want the
manuals. I convinced him not to throw them away, but we never worked out
shipping arrangements when I told him I was somewhat interested in them.
This should be a fairly complete set, but email the seller if you have any
questions.

He may also still have a BA350 available.

Merry Christmas to all!
Obligatory pre-feast Christmas posting...
Hopefully there's some UK telecoms people on the list who can tell me
some more about these. I unearthed a pair of BT modems (look to be from
the mid 1980s), badged as Datel 4961x's.
They're in nice finned metal cases (with plastic end caps; Datel unicase
4001X's) - I think I hung onto them intending on using the shells to
house a pair of amplifiers, having never had any luck getting the modems
to work.
I was about to scrap them, and opened them up to strip and useful parts
first. Now I'm curious.
There's a *lot* of silicon inside these things. Most of the larger chips
appear to be custom, badged in a range from MS2006 to MS2011. One of the
40 pin chips carries the marking "BTRL / 403 / 5113". British Telecom
Research Labs maybe? There are three OKI 40 pin chips too, several ROMs,
and no less than 42 DIP switches internally.
There are six fuses inside - they didn't hold back there.
The rear of the case has a 25 pin DTE socket, a telephone pass-through
socket, PSTN socket for connection to the network - and also a
mysterious "PC" socket (same type as used for the phone network
connection). Any idea what that's for? ("Private Circuit" maybe)
The front has push-switches for 4800 baud operation, plus AL, ST, RDL
and DL. I assume ST is self-test, but I don't know what the others are.
There are status LEDs for 4800 operation, DSR, RFS, TD, CD, RD and test.
Those all make sense.
I remember I never got one of these to talk to a remote modem of any
type. I'm wondering if they're supposed to be used in pairs (or talk to
some specific remote equipment that I don't have) and use some sort of
non-standard data compression, or even encryption.
Any ideas anyone? Anybody know of any UK telecoms lists where there may
be people who can help?

I've got a copy of Unix Wprowadzenie that I'd like to find a good home

Anyway, if anyone can use this, let me know and you can have it for

Try also amateur radio clubs, as they typically have "old" equipment,
including computers (for packet radio), and computer flea markets, if
there are any near you. Here in Boston there is a monthly electronics
and computer flea market at MIT monthly during warmer weather. I myself
am a packrat and have probably a half dozen under 500 MB and another
half dozen up to 4 GB. If you can't find a local one, pay shipping
and a few bucks for my time and I'll send out a couple.

I just unearthed a VT320 terminal at the very back corner of one of my
store rooms.
Before I go any further... should it work with a VT220 keyboard? There
was no keyboard when I found it years ago, but I do have a couple of
VT220 keyboards lying around.
Secondly - it doesn't seem to be getting any HT output to the tube. The
green LED D509 is pulsing about once every second.
Is there a common failure mode for these things?
I'm not too fussed about fixing it as I have a couple of VT220s that I
can use as 'real' terminals anyway. If anyone wants it for spares
they're welcome to it (I'm in Cambridge, UK)
cheers
Jules
The LK201 keyboard is used across the 2xx, 3xx and on some of the 4xx
terminals, so yes, as I remember, the vt220 keyboard will work with the
vt320.
Can't help with the diagnostic. I am sitting in front of a VT330 now, and
I just looked at the manual for it. it says if the power indicator flashes,
check the ROM cartridge on the rear has to be inserted correctly. I didn't
think the VT320 had a rom cartridge, so that troubleshooting probably
won't help.

Hey, all:
The holidays have me in New York for a week or two, and since I'm here
anyway I thought it might be fun to spend some time looking around for
a few odds and ends I could use at home, and perhaps some DEC items that
have been on my wish-list (and, yes, that PDP-12 I'm still hoping to
find somewhere! <g!>). I have, however, all the ignorance of your
standard tourist. :/ Anybody have any suggestions of good surplus
places in, or cozy to, the city? Any suggestions would be greatly
appreciated.
As long as I'm writing to everyone anyway, I'll add: Merry Christmas
and Happy New Year and all that. :)
-O.-
Nope, none of those type disks. The disk is a 2870 (iomec 1000) (which is
what I am trying to test / repair).

I have a bunch of docs for this. Hasn't been a need to get them on line
before now, so I'll move them up in the queue.
DEC actually sold them in the RK8 (not RK8E) which was a whole rack of
M series modules before switching to Diablo, then doing their own (RK05)
I know they are Kanji (SP?) terminals but that is all the information I have.
Does anyone have a manual or more information?
I am more than happy to pay for any copying costs.
Thanks

drive I need to use for a replacement?
I haven't even ventured to see how to go about opening the machine yet, so I

Hi,
Just made a search at ebay for "option board" and
found nothing.... Do you remember how it was describet
at ebay ???
BTW, the way I wanna go is the cheapyest/easyest. I
have about 30 apple II disks (both sides) fulled of
binary files (old brazilian pinball rom files for
eproms 2716, 2708, 2732, 2764), and need to put them
at my PC, since I don't have an apple anymore and my
eprom burner only works with PC.
If that software I mentionned works, I guess it would
be the best solution. If not, I prefer a PC card,
since I don't have enougth space for another computer
(an apple II, i.e.).
[ ]s
Silvio Finotti
There is a Option board on ebay now in mint condition
with software if thats
the way he wants to go. I dont see why people go to
all the trouble to buy
exotic gear and get it to work when the original
equipment is so cheap and
WILL work. Its not like he has 10,000 disks he needs
to get data from where
an automated PC setup for reading and dumping the
contents to a HD would be
better.

And I am an active archivist of old software who works for groups around
the country on a pro-bono basis who has been trying to find a 10" 7 track
for years now.
People on the list can make their own decisions about where a drive should
go if one should ever turn up.
FWIW, 7 track drives are going for $3500 and up when they do show up.
I was happy when I found a write-only 7 track head stack for only $500
a few years ago.
Does anyone on th elist have an Intel SIM-8 or at least some good
pictures or drawings of it? I found a part that's marked SIM-8 and I'm
wondering if thats what it's part of.

This is a famicon clone and was in the box but is missing the manual. Could
not find anymore details about it using google. Anyone have one of these and
knows if it will take famicon cartridges? Thanks
Hello,
I recently found a brand new Marpet board still vacume sealed for my Mega 4 ST.
The catch is that it has no disk with it. I ran across a post in a web-search
where you claim to have an installation manual (which I also have). I'm hoping
maybe you have the software and could zip it up and email it. I'd be very
greatful indeed if you would.
Thanks,
Brian

You can read more info at the downloadable zip file.
The "Disk2fdi.txt" will describe what the software can
do.
Take a look at the "Rawflopy.doc" file. There he
describes how to "fool" the FDC (floppy disk
controller) and read "other format" data. It makes
sense, and worth a try.... As soon as I find a 5,25
drive I'll try it....
As he describes, it's necessary one drive (can be 3,5
or 5,25) with an IMB/PC formated disk and a 2nd drive
(5,25) for the apple II or other formats disks.

That's done !!! When/if you find them let me know,
please.

That's done too !!! Don't forget to tell me when you
find them (silviorf(a)yahoo.com)....

> One more question, what is the best way to clean the heads?
DO NOT TRY TO CLEAN THE HEADS!!!!
Read the documentation in the cdc and dec sections of bitsavers
on these drives.
3330 style heads fly a LOT lower than RK or RL heads, and they
warn not to try cleaning either the packs or the heads because
it is impossible to get all of the residue off of them.
I HAVE a Deluxe Option Board. I am trying to get it to write to a 1.44
floppy. Is there a limit to cable lengths being used before problems
arise? TCM & TE both read 1.44 floppies just fine, but the write
functions do NOT work for me. It has been over 12 years since I have
used this board and I may be missing some steps. I have a printed manual
and I have tried everything I can find in it. Now I am in need of
"experts" suggestions to get it going.
I am trying to copy a plain 1.44 Mb floppy as an exercise. I want to
copy tracks 80-81 to see if that captures some copy protection of a
protected disk. (The company does not replace lost disks, just SELLS you
another registered copy) Running diskcopy gets you an Unregistered copy.
Doing diskcomp shows them to be identical. The difference must be in
tracks 80-81 or other places diskcomp doesn't pay attention to.
Oh, how I've missed discussions like this!!!!
I have been involved with RT-11 and PDP/LSI stuff since 1974, and belonged
to the MIT local users group/special interest group until the mid 80's. I
loved (and still do) this stuff. For a while I also ran the VAX 11/780
cluster at Northeastern University when it was first brought in, but I
always liked RT-11.
Currently in the lab at Northeastern I contract with, we have a couple of
microvax II's, and a few LSI-11 systems (all 11/73). I have done some
hacking of the operating system for real-time stuff we needed in the lab,
and also built custom q-bus boards for the lab. So I have a bit of hardware
and software expertise for RT-11/Qbus. I felt lost, in a vacuum of sorts,
when DEC was bought out, the LSI-11 stuff discontinued, and no local user
group to speak of.
I was also one of the voices asking for RT-11 on the VAX architecture, as
we saw the end of the PDP/LSI line coming, and no good replacement. Well,
I never saw it, but at least I can run some of our stuff on a PC with
emulators now.
I have close to 100 boards as spares now, even I think a T-11 SBC, and
as soon as I can start moving the stuff off the LSI-11 systems, I will
be getting rid of them. I already owe two systems to people who have
asked for them, Curt(atari) and jcwren. Now that I have my two radio
towers up and the weather is forcing me to work indoors, I can get back
to what I promised people on the list.
I recall that I took the images from a PLUS board (with the MSCP code)
and burned it into eproms and then stuck them on a MXV-11, so you could
say I didn't always do things kosher, but then again it worked. With
that setup, I could use just two dual boards to make a small system. The
"disk" was the TU-58 on the serial port on the MXV-11.
So you could say I was an addict for this stuff, and I have found a home
among fellow addicts/fruitcakes/junkies!!
My only request is if anyone knows of another list/group I should join
that is more specific to RT-11/LSI-11 stuff, please let me know.

Couple of new Research Machines finds just turned up:
A 380Z in great condition, with the added bonus that it came with all
the manuals. Quick look inside shows it to be pretty stock, except that
I was told it had some sort of silicon disk option fitted. It does look
to have a memory-type board hooked up to the bus that I wasn't
expecting. Currently drying out prior to strip-down and checking as it
had to overnight in the car...
An RM NB300 laptop. Bet there aren't many of those about (I confess to
not even knowing that RM made a laptop until the guy I got the 380Z from
suddenly remembered that he had it!). Looks to be fairly standard stuff
inside - Conner crap-o-matic 40MB IDE drive, 386 cpu, 4MB RAM etc. but
probably a quite nice spec for the time.
The internal keyboard cable (one of those flat ribbons) is snapped -
anyone know of a UK source for them? Othwise I'll just have to keep an
eye out for replacements in broken laptops...
Oh, I also got various bits of software for both machines - system
disks, Windows 1.0 for the laptop etc.
cheers
