Well, dang it... I'm running out of room, and I really don't have the time
that this gorgeous old beastie deserves, so....
Here's what I've got. A complete H89 system as follows.
System unit with internal FD -- no screen burn that I can see, very clean.
External dual FD. (all FD's are 5.25" hard-sectored 40 TPI).
Cassette I/O board.
OkiData Microline 82 series printer.
IBM "Plug-and-Play" EPROM kit for the OkiData, something about 'Block
Graphics.'
Extra printer ribbon, still in the shrink wrap.
Spare chips: 4116-25, 74S132, and 74LS186.
PROMs (Heath/Zenith part numbers on the labels): 2 ea. 444-43
EPROMs (a pair of 2716's, also with H-Z part numbers on the labels): 444-40
That's the hardware. About the only thing that's missing (God only knows
why) are the hardware manuals.
I do have the following software for it, with manuals.
CP/M-80, Ver. 2.2, Heath-Zenith tagged.
'Ed-a-Sketch' graphics editor.
'Reach' modem and file transfer program.
PIE 1.5 full-screen editor.
HUG Utilities and BASIC-E disks.
NewWord Word Processor, ver. 2.17
JRT Pascal, V. 3.0.
Space Odyssey 1
Microsoft BASIC Compiler on original 8" diskette, ver. 7032.530
Spare diskettes (at least a box worth).
Please to make me an offer on the whole schmeer! I know I can trust you
lot to make it a fair one. It would probably be best if said offer came
>from someone local (Seattle, Portland, etc.). I can ship the stuff, but
that could get costly even with UPS Ground. Some of the units are pretty
heavy!
Thanks in advance.

I have a friend who has 6 Sparc SLC's with either dud power supplies or

easily? Not having looked at them myself, I would expect that they are a

Has anyone tried wiring an 8" RX52 floppy straight to a modern PC
controller? I did the best I know how, and I *appear* to have a
semi-functioning device attached. Trying to read/format the disk
>from Linux causes the drive to access; however, trying to format (even
with PUTR under MsDOS) gives me a verification error and an error about
Track 0. Does this sound more like a media error? The disks (Dysan
101/1) appear to be in fine condition, having been stored in rigid
notebooks in plastic sleeves for the last 10 years or so in a
"media-friendly" environment. There are also lifecycle logs in the sleves,
which indicate that they were initialized and only written to once.
I've been digging around, trying to get enough information to attempt to
set up Forth on my OS-less 11/23, but I don't have another functioning
system to work with (the chicken and the egg). Am I dreaming that I'm
going to be able to get anything accomplished with an emulator and a pair
of 8" floppys Frankensteined to my PC?
On a similar note, does anyone happen to have a Compaticard for
trade/sale?

They probably called it a 5126 because it has all the diagnostic stuff.

Hmmm... Not shown in my RQDX3 manual, nor on any of the microfiche I have.
At first I thought you might mean W23 or W12/W13, but they're on the left.
I suspect they're some factory test setting. If I have the time, I'll
pull one of my RQDX3s this weekend and have a look -- though just looking
at them may not do much good, of course!

Sounds like all the jumpers (except possibly W23) are set up right, then

Which jumopers?

If your ROMs don't support RX33s, there are two problems that may prevent
the RQDX seeing the drives as usable.
First is that an RX50 responds with a READY signal as soon as it's polled,
if there's a disk in it, because the READY signal is really a "disk in"
signal from a set of contacts. Most drives respond with READY only after
the disk is up to speed, since the signal is derived from the index pulses
(the original meaning of the READY signal was that there is a disk in, and
it's up to speed, as determined by measuring the time between two index
pulses). The 200ms (minimum) delay prevents the RQDX seeing the disk.
Second is that on an RX50, the SideSelect -- which isn't normally used,
since an RX50 is really two single-sided drives -- is used to disable the
TrackZero output. The RQDX tests for an RX50 by stepping to Trk0, checking
the output, setting the SideSelect, and checking that the Trk0 signal has
gone away.
I guess these tests are probably because the RX50 shares some signals with
the RDxx drives on the same distribution board.
I have two or three Canon and Mitsubishi drives modified to work like this,
and they work fine on RQDX2s and 3s. Unmodified, they don't. In fact, now
I think about it, I have a feeling those drive "fixes" are needed for the
243/244 ROMs as well.

What is an RX52 floppy? I'll presume you mean the rather large dual
drive RX02. The DEC 8" floppies are RX01/2 and have their own internal
controller. That would make RX01 or 02 disk system very hard to wire
to a PC floppy controller, like near impossible.
FYI: The DEC RX02 DD format is not readable by any standard floppy
controller chip. RX01 however is standard 128 bytes IBM softsector
format.
RX50 drives are fairly easy to wire to a PC it is however single sided
and dual drive with one spindle. The later item will cause all mannor
of errors if the driver doesn't internally know the two drives have a
common positioner. However FD55s jumperd for slow spindle and only
using one side work better!

Compaticard can only read RX01.

I just grabbed a Rainbow out of the garbage with the garbage truck
literally meters away from getting it. After major industrial cleanup
(removing the half gallon of house paint from it and the cigarette goo),
Its up and running mostly. It came with the MS-Dos 2.05 OS, some
manuals, and thats it.
I know diddly squat about this beast (other than the legend of
it possessing two CPU's) and CP/M. So this is a very basic question. When
I get to the menu at boot up it recognizes a: and b: (though a: is a bit
wonky). It will also respond to W which tells me that
there are two cp/m partitions: e: and f: however, when I try to go to
them I get a "message 23 - Non-System Diskette". I seem to be missing the
manual with numbered error messages. I'm assuming that this means that
there is a hard drive problem. However, it is recognizing the partitions
so something is being read. I also don't have the CP/M diskette, only the
DOS. This DOS doesn't have FDISK so I can't look at the partitions via an
OS I know well (though I could do it through debug but I'm being lazy
here), and when I bit the bullet and tried to format the hard
drive it keeps telling me to stick in the diskette to format.
Any help would be appreciated otherwise I'll do a low level
format on the segate drive and pray to the appropriate dieties.

There was a 101 keyboard sold by Tandy that did work with the old 1000
SXs. It has dip switches that had to be set correctly. I think it was
marketed under the name Keyboard 1000 or 2000. Anyway, they were quite
expensive (about $100) and we bought a few to keep our old lab going a

Hmm... I've had this problem from time to time with Pine (a well-known but
in some respects very iffy UNIX mailer) and with other mail software based
on similar library code (elm, and a new GUI one whose name escapes me).
The author of the library made some unwarranted assumptions about what
exactly are the rules that govern separation of messages in a mailbox, and
the allowed formated for the date, with the result that messages sometimes
get stuck together. The author forgot the adage "be forgiving in what you
accept and strict in what you transmit". It's my pet hate at the moment

Perhaps yuo have a similar problem, either on your local system or your

Looks like the Albuqurque Altairs are coming

a 680b to go with the 8800bt.
If anyone was monitoring the auction of the
680 a couple of weeks ago which did not meet the reserve
price of $2500 - thought you might be interested
to know that it was bought by a buyer in Italy
after the auction. The purchaser bought it only
to trade for an original 8800 which he has done.
It will be interesting to see what happens with
these 680's currently up for auction. It appears
that the eBay bidders are not very aware of the
scarcity of the 680 and are consumed by the hype
surrounding the 8800.

Well I recall they were sold by Montgomery Wards in the U.S. for a couple
years also the carts I had once bought had Macy's or some other retail chain's
tags on them, so they were well mechandised. But they are somewhat uncommon nowadays.
The Atari 2600 beat them out of business though, pitty, the Fairchild had
some of the coolest joysticks (controls were left, right, up, down, twist
left, twist right, fire (and I think push down))

Actually, those Eagles you have are 10.5" drives. Earlier Fuji's, like
the 2281/82/83/84 series, were 14". (And also had nice transparent HDA
covers so you could see the heads seeking across the platters.)
Just look in any issue of _Processor_ and you'll find many minicomputer
dealers selling 8" SMD drives like the Fuji 2333's and the like. And
there's a dealer who posts to the Usenet PDP-11 newsgroups every couple
of months with 5.25" Hitachi SMD's for sale.

hardware rags to promote their modern drive systems that replace vintage
ones. In particular, they sell the electronics that will make a single
modern SCSI drive look like many RK05's, Diablos, Massbus disk, or
SMD disk. Thanks to their efforts, hundreds of classic
mid-60's IBM and DEC systems are still running at many sites doing
important work!
The Wilson Labs systems aren't cheap, though :-).

Thanks for posting it Allison. I'm not sure of make. It is an old one

Otherwise, your guess is better than mine. I have no documentation for
it.

I have found an ancient PROM burner, a Data I/O System 19, with a Unipac
module fitted. Test stickers on it are dated 1980.
It came with an "Operators Synopsis" with which I am totally out of my depth
and a wall chart dated 1985 with details of PROMs of the day and which
Unipak revision applies to which.
??????????
I had hoped to be able to use it to back up older ROMs which my circa 1995
EPROM programmer can't handle. Is it usable for this?
It has a serial type connector but no software (it predates the PC). There
is an LED and a hexadecimal keyboard. It looks like it was meant to be used
manually !! Typing stuff in character by character.
There's nothing on Data I/O's website about this and they haven't replied to
my email as yet.
Can anyone offer advice?
Thanks

Are these PC clones? I have seen a tandy (1000, I think) that had a
microphone port. Why was this? I have also seen a tandy which was
sort of like a C64 except it had a 3.5" disk drive. I'm _certain_ it
was a tandy.

The 680's are nice, but the 1500 minbid limit on
each is way to high. I did send the seller a mail
with an reasonable bid - so maybe they end up in

We're located in northern VA, 7 miles from DC. The challenge is to get
the old stuff in the hands of those who want it so it doesn't wind up in
landfills.
We used to have "yard sales" to clear out the old stuff, but I got tired
of answering questions/complaints months later from people who bought an
entire system for $10, so eventually we just set the stuff out and let
any interested people take it away. With our student population
increasing, we're using every available space as classrooms.
Write me at backofene(a)hotmail.com if you want to help us "take out the

I've got the service manual that I used to use when I
supported them. I still have a couple of drives though
so I don't want to lose it. I could make a copy given
enough time (it must be ~200 pages). I was planning
to do that at some point since there's someone else
on the list that I promised a copy to (I'll have to dig
up that message to find out who).
Do they have an urgent need or are they just trying
to prepare for when they need it?

Now a question for the real wiered stuff:
Does anybody know a Wang-71 ?
I just know the name - I'm right now on a trace of
a specific Russian computer, and they told me that
this machine is a Wang-71 clone, but I can't find any
information about this machine. No, I have no pictures
of the Russian machine and no further data. The clone
is build 1975, so the original design might me a bit
earlyer.

I am not familiar enough with both machines to make a judjement on which one
is better but the franklin display some features that seem interesting:
apple dos 3.3 compatibility, floating point basic, apparently could run CP/M
or Pascal (OS?)(not much info on that), programmable function keysimpressive
display capabilities (16 colors at 560 x 192), built in parallel and serial
interfaces and memory expandable up to 576K.
Compare that to the Apple IIe or IIc. The memory extension and RGB interface
cards are optional (128K and 80 column color?)
It's hard to tell what the exact caracteristics are the users manual keep
refering to the technical manual that I don't have.

Since you've got a WQESD, you've got two choices with respect to
partitioning:
1: Hardware partitioning.
Partition your 150 Mbyte drive into multiple 65536-blocks drive
through the WQESD firmware. You don't need to do a reformat from
scratch; just redefine the disk structure and write it to disk.
2: Software partitioning.
Partition from RT-11. Assuming your drive is at LUN 0, you
already have the default mappings SET DU0:UNIT=0 and SET DU0:PART=0.
The "UNIT" refers to the MSCP LUN of the drive, and the PART
refers to the software partition number.
Map DU1: to be the second logical partition on the first MSCP
LUN with SET DU1:UNIT=0 followed by SET DU1:PART=1.
Continue on up until you've used up all the disk. Each PART
refers to a logical partition on disk, each of which is 65536
blocks long (except for the last one, which is whatever is left
over.) Of course, only the first 65535 blocks of each partition
are directly usable, given RT-11's block numbering scheme.
SHOW DEV:DU will show you the current partitioning.
Keep in mind that if DU is your system disk, you'll have to do
a reboot to reload the driver with the "new" partition settings
before they'll go into effect. (You wouldn't believe the number
of RT-11 5.7 field test sites who complained "partitioning doesn't
work" when they simply failed to reboot after the SET DU's! This
has been in the manuals for over a decade!) After rebooting, INIT
DU1:, etc., and away you go!
Since you *do* have the WQESD, I heavily recommend that you do your
partitioning at the WQESD level and not at the RT-11 level. This way
all your partitions will be hardware bootable. If you do the
partitioning through RT-11, the resulting logical partitions won't
be hardware bootable.
A neat tool (hey, I wrote it, I think it's neat) for looking at MSCP-
level stuff under RT-11 is the DUSTAT program, available from
ftp://sunsite.unc.edu/pub/academic/computer-science/history/pdp-11/rt/dusta…

By default, if your disk is larger than 65535 blocks, the physical unit
numbers for the DU device map to partition zero (0-65534) of the
selected physical unit. If you want to map another unit of the DU
handler to another partition, you issue the command:
SET DUn UNIT=m part=p
where 'n' is the RT-11 unit number, 'm' is the physical unit number in
your MSCP configuration, and 'p' is the partition number (starting at
zero).
For example, say I have an RQDX3 with an RD54 (169mb) and an RX50
(dual drive):
DU0 = Partition zero (0-65534) on phys unit 0 (rd54)
DU1 = First of the RX50 drives
DU2 = Second of the RX50 drives
If I want address more of the RD54, I can do the following:
DU0 = Partition zero (0-65534) on phys unit 0 (rd54)
DU1 = First of the RX50 drives
DU2 = Second of the RX50 drives
DU3 = unassigned
DU4 = Partition one on phys unit 0
(set du4 unit=0 part=1)
DU5 = Partition two on phys unit 0
(set du5 unit=0 part=2)
DU6 = Partition three on phys unit 0
(set du6 unit=0 part=3)
DU7 = Partition four on phys unit 0
(set du7 unit=0 part=4)
This is, in fact, how many partitions you would get on an RD54. All
of the partitions except the last one will be full 65535 block units.
The last one is about 7k blocks.

Looks like the Albuqurque Altairs are coming
out of the woodwork. There is now a 680 and
a 680b to go with the 8800bt.
If anyone was monitoring the auction of the
680 a couple of weeks ago which did not meet the reserve
price of $2500 - thought you might be interested
to know that it was bought by a buyer in Italy
after the auction. The purchaser bought it only
to trade for an original 8800 which he has done.
It will be interesting to see what happens with
these 680's currently up for auction. It appears
that the eBay bidders are not very aware of the

That sounds suspiciously like what the controller does to "sniff" an RX50.
There's a bit of majic between the side select and track zero signals on
an RX50, which the controller uses to test that it's a real RX50.

That's 23-216E5 and 23-217E5, the first version of the RQDX3 code. The
second revision is 23-244E5 and 23-245E5, which I think does support RX33s.
The 23- means a ROM and the E5 means 16Kbytes (ie a 27128 EPROM).

There was a third version, which was a minor bugfix, 23-285E5 and 23-286E5.
I'm looking for a copy of those for my archive...

The "twist" cable only applies to PC or systems using PC patterned
interfaces. It DOES NOT APPLY TO RQDX and distribution boards used in
Qbus systems.
RQDXn uses a single bussed motor on and drive selection by drive select
jumper.
If you use a RX33 drive try using only one for starters, that will lower
the sillyness factor. If you media is RX50... why not use an RX50.
If all else fails and your configuring a second system move the controller
that works over to the target or move the target controller to the running
system as a second drive/unit.
Allison
RX33's use a straight cable without the PC twist. I have several here but
use only one at a time on my test beds. I have several from various pieces
of DEC equipment and they all use the drive select jumpers with a straight
cable.

Do the drive spindle motors ever run? You can't read data from a disk
that's not spinning.
I am almost sure you need a cable without the PC-twist. Also, you
probably need to set the drive select jumpers properly (Can somebody tell
us what to?). Remember that the PC-twist not only swaps over 2 of the
drive select lines, it also gives separate motor on signals for the 2
drives.

Absolutely correct.

There's absolutely no need to guess on this subject - Terry Kennedy has
collected a great amount of wisdom and experience on this subject in
THIRD-PARTY-DISKS.TXT, a compendium of DECUServe conferences,
available by anonymous ftp from ftp.spc.edu.
The answer for the drive select jumpers is easy: first drive at DS0,
second at DS1. The jumpers selecting motor speed control are a bit
more complicated; Terry's collection of data covers several popular
Teac drives, and if the answer isn't there browsing through the
Teac jumper setting recommendations will quickly give the answer
for any specific drive they've sold. Teac's faxback service is at
+1 213 727 7629, and is a valuable source of technical data regarding
the various drives and options they've produced (and still produce.)

Hello All,
Who can help me with a pair of RL01/RL02 slides and the 4 brackets?
I want to mount my 3rd RL unit in the cabinet but don't have a 3rd
pair of them.
A payment can be discussed.

Keep in mind that early RQDX3 revisions don't know how to talk to
RX33's - they're limited to RX50 floppies. Seeing as how your system
is apparently doing bizarre things with the RX33's, this might be the
case.
What exactly do your "RX33's" do when you try to access them?
What firmware revision is your RQDX3?

Yes.

To get RT-11 to deal with two DU controllers, you can either:
1. Do a SYSGEN to create a DU handler that can handle more than one
DU controller. With recent enough RT-11's, the same handler
copes very nicely with multi-port booting.
2. COPY DU[X].SYS to another name (say, DG[X].SYS), and then SET DG:CSR=nnnnnn
and SET DG:VECTOR=nnn, where nnnnnn is the CSR and nnn is an unused
vector in your system. When you create a bootable floppy which you
want to be bootable on your second controller, you must lay down the
DG bootstrap instead of DU, since the DU device points to the wrong
controller.
The tradeoffs between the above two methods are documented in the
RT-11 _System Generation Guide_ and the RT-11 _Device Handlers Manual_.
Method #2 above is easily the quickest, and will probably do just fine
for your purposes. (Though a RT-11 system with extended-unit multiport
DU handler is a beautiful sight!)

Look for the file MUB.COM on your distribution:
! COPYRIGHT 1989, 1990 BY DIGITAL EQUIPMENT CORPORATION
! ALL RIGHTS RESERVED
!
! MUB.COM command file used to build binary kits
Again, it will depend on which version of RT-11 you're running whether
MUB.COM is MU-bootability is present.

I had to trade back some RQDX2s for RQDX1s on some PDP-11/73s I delivered
to the gummint because RT-11 didn't support them. I don't recall which
version we were using; it would have been at least 5.0. I remember
grumbling about how fancy (read "bloated") RT-11 was getting, but I don't
recall doing _that_ until 5.2; I thought it happened during the 11/73
incident, though. I also don't remember why I thought 5.2 was bloated
(it may have been the UCL/UCF stuff, which I thought was unnecessary),
but I did stash away a 5.0 distribution kit as a hedge against bloatation.

Yes, the UCL stuff is unnecessary, which is why if you don't want it
you simply answer SYSGEN question 100 with "NO":
100. Do you want the user command linkage (Y)? $
USER COMMAND LINKAGE OPTION:
The user command linkage allows you to define your own commands
which can be issued in a format similar to the standard DCL
commands.

> but I did stash away a 5.0 distribution kit as a hedge against bloatation.
An even better hedge against bloatation is to get RT-11 5.6 or later
and learn how to use SET RUN VBGEXE. No matter how big the monitors
and drivers grow, by appropriately setting a .SAV image's VBGEXE
bits you can give it access to "all" 56kbytes of virtual memory space. If you
want direct access to I/O space, you can turn that on too, or you can
also elect to have 64kbytes of virtual memory space available to your
process if you don't need direct access to I/O space.

Found an old modem that I forgot I owned and was just wondering a few things.
First, it's a Concord Data Systems 224 ARQ/Autodial that I now remember was
in tow by a 3B2 I picked up a while ago. Anyway, it's rather heavy (humongous
hat sink on back) so i opened it up and began to think that the innards seemed a
bit complicated for a 'modem.'
OK, I'll admit it, I was 11 years old when these things would have been in use,
but I have other modems from the peiod ('85-'86) that aren't nearly as complex.
It's about the size of a large book and has three levels of circuit boards
with a
Z80 CPU, an SIO chip, and memory chips (one says "zeropower (tm) ram" on
it and "DO NOT DISPOSE OF IN FIRE!!!!") on one level, Intel 8031 series chips
on another and who knows what on the bottom (haven't taken it all apart yet).
Not to mention the 32 dip switches (all off) and the 23 led's on the front.
To make a long story short, what did/does this thing do that a regular modem
of the time didn't do?
Thanks,
les

I don't really know yet. I would believe that they added some features but

All I can do is look at the specs and compare the two.

Yep. They're PC/XT clones. The Tandy 1000TL's had the microphone port.
They had a built-in "Tandy Sound Chip". It put out better sound (in Tandy
1000-supported games) that the standard PC-speaker setting. Haven't gotten
the mic to work yet, though. I wish I could find a driver that would run
the chip through Windows...
I have seen the type that looks like a C64 (can't remember if it was a 1000
or not. They did make the CoCo series, but they didn't have the disk
drives. If anyone has one of the 1000's (?) with the built-in drive (and
keyboard), and you want to sell it, send me an email, because I'm probably
interested.

If the plug on the RL has a DIN plug with (8?) pins (one in center), then
the keyboard from the SX or TX will work. If it's a standard 5-pin DIN,
then just use an XT keyboard.

Yes. In fact, the RT-11 distribution on 5.25" floppies is RX50
compatible, which also works on RX33. If the disk is formatted
by an RX33, then it will only work on an RX33, though (at least
when using the RT-11 FORMAT command).

Since you're using the distribution kit, the answer is no. The address
which the distribution handler (a single-port handler) expects is the
primary address, 17772150. Even if you were able to get the boot code
to read the boot block into memory, the first time the driver gets
control, it will try the default primary address and fail.
>Is it possible to create a Bootable TK50 with RT-11 that can be used to

Even when I worked in the RT development group, I avoided the attempt
at making bootable magtapes... But the answer is, yes... you could
make a bootable magtape (TK50). But you need to boot an RT system to
do so, so we're back to a chicken and egg problem...

The problem with this technique is that the handler name is built into
the driver, which is used by XM to locate the extended memory region
used to store data (and other code), and the two handlers would still
have the same name. You would need to SIPP the new handler and search
for all references to the name 'DU' (search for ;rDU) to 'DG' (;rDG).

OK, I've got some more questions. It seems I've finally got the PDP-11/73
I'm working on to talk to the floppy drives. BUT, it won't boot my RT-11
RX-50 floppies.
I'm using the RQDX3 controller as the floppy controller and the WQESD
(ESDI) controller as the boot device. When I tell the system to boot from
DUB0 or DUB1 which is the terminalogy that the WQESD controller expects
(figuring that out, i.e. reading the manual took longer than I want to
admit) with a RX50 attached, it will access the floppy drives, this is best
evidenced by my using a cleaning floppy in the drive (made it easy to hear
the drive being accessed).
When I try using a pair of Teac floppies I've converted to RX33's using
information I found on Sunsite I'm not really sure it tries to access them.
How do you cable RX33's? I set them to Drive 0 and 1, as the docs said,
and then used a Y-splitter for the power with a standard PC floppy cable
(do I need one without the twist?). Can you use RX50 floppies to boot a
system with RX33 drives?
Will RT-11 boot off of a floppy drive at CSR 17760334? I've tried with
both the Boot disk from my RX50 distribution set, and a RX50 boot disk that
I made using PUTR. I've a sinking feeling that having two disk controllers
is confusing RT-11.
Is it possible to create a Bootable TK50 with RT-11 that can be used to do
the install?

They are Apple IIe and IIc compatibles with 128K RAM,80 Column video, Double

Right... but default secondary device for a DU handler is 17772144.
(The reason for this is because back when the driver was developed,
someone decided that since the vector was programmable, and the default
was at 154, and nothing was at 150, that subsequent vectors would
decrease by 4. This was then extended to the CSR... It wasn't
until later that we found that the default secondary CSR was to be
at 17760334. It never got changed. I think it is still that way
for the to-be-released V5.7)

So long as the address/vector match what is set in the device handler,
it should boot. (I have a system at home with three, and at times
four, MSCP adapters for various disk types -- MSCP, SCSI, ESDI, DSSI)

Either ways it's not an issue ans the numbering system is more than 4

8550-021 (PS/2m50). How else would they differentiate models in a

I can't check for a model number, because I no longer have the drive. I do
remember that it was all black, had a Disk II - type face (with the
non-wheel head motor), and that it said "Apple" and had a red apple (not
multicolored) on the front.

Yes, it turned the rest of the Digest into a solid block of text.
I just gave up on trying to read it.

I read that you have some that may use old computers. I have 3 of them 1 128
commador and two 64 with about 200 programs and game and a lot of blank disks.

In a message dated 98-10-13 20:40:07 EDT, you write:
<< he few ISA cards was a 16-bit double card with a 9 pin external plug

Wyse monitor. There's 2 badly mounted Wyse E-Proms. Printed on the bottom of
the top board was WY-700 Controller Daughterboard. Wyse Technology (c) 1986.
The bottom one has WY-700 PC HI RES MOTHER BOARD. Sounds like your beast.
If I should find one of these monitors would it work on a clone with just
this card ?
T >>
Yes if you plug the card in and plug the matching 700 monitor in it will come
up. The card emulates EGA & CGA. In its high res mode it is a nice sharp
1200X800 (approx.) monitor. It was supported by many early desktop publishing
software packages in it's high res mode. The original card & monitor set
predated VGA and was an 8 bit double card. I used one on an XT for several
years. SVGA finally killed them off.
I think I still have that XT. I know I have two of the monitors in my whse, If
I don't sell them beforehand they will be in my Auction in early November. I
am retireing from supporting a warehouse so most everthing is selling. This
will include lots of older computers, parts, terminals, printers and lots of
collectable stuff.

The situation is complicated by the large number of "Disk ][ clones"
that were produced in the early 80's. From personal experience and
advertisements, I'd say there were at least 30 different clones at the
time. Most of them used very different-looking, often half-height, 5.25"
drives, but many used the same drive mechanics as a real Disk ][ and
had case designs almost exactly like a real Disk ]['s. The only real
way to tell in this case whether you're dealing with a clone or not
is to look for an Apple sticker on the box and/or the Apple legend on
the drive's PC board. (While some of the clone makers also stole
Apple's PC board layout, I've never seen any that went so far as to
steal Apple's copyright and part number!)

The situation depends greatly on *which* version of the DEC boot
ROM's are in use. Some automatically search for an alternate CSR,
some allow you to specify it explicitly.
The situation is complicated by the fact that for most DEC OS's,
the alternate DU CSR is 160334, while for RT-11, SYSGEN will certainly
suggest something very different for the default:
> 230. What is the CSR (register) address for the second port (172144)?
While most DEC DU bootstraps "sniff" through 172144, not all do.
Luckily, we don't have to argue about the situation, as Zane told
us which bootstrap he is using:
>When I tell the system to boot from
>DUB0 or DUB1 which is the terminalogy that the WQESD controller expects
So any discussion of DEC bootstrap revisions seems to be quite
irrelevant :-)
For many purposes, I much prefer the WQESD boot scheme. It
avoids all the confusion caused by the many, many different DEC DU
bootstraps!

Ok, TEAC FD55GFV (RX33) or TEAC FD55F (RX50). The cable must not have
twist and drive select is 1 for the first, I only use one on the system
as I have 3 RD52s. IF the drive speed select and density select jumpers
are set right it (using RQDX3) will sense what the media is and operate
correctly using the DU boot. None or all of this will be true for the
WQESD controller, I don't know it.

17772150 it the default first device and the default bootable. If there
is two the second will be at 17760334. For RQDXs the LUN jumper must
corospond to how many units.
I believe PDP-11 ROM BOOT expects to boot from the default first (*2150)
unless the DU.sys driver has been changed for the second address. RT-11
itself will boot/run on anything you have a driver for. Megan would
know for sure. I've never found it necessary to have two MSCP disk
controllers in a PDP-11 (I was using them in the vax instead!).

That's oblique. It's possible to make a bootable RX50(or RX33) that is
complete enough to be a system! To install from that is trivial as it's
really INITing the target drive (assuming its LL formated) and copying
everything to it then doing a copy/boot operation. Not much majik unless
the version of RT has been really tweeked.

Do you know if it's described in any magazine article? There is a 3 part
series about the first MMD in the May, June, July 1976 Radio Electronics. It
is an 8080 based system with 24 output bits and LED's, keypad, a solderless
breadboard, 256 bytes ram (2x 2111), and 256 bytes rom (1702A). The article
has the schematic and "monitor" listing and sample programs. I almost bought
one a few years ago, but the price was too much, USD $150. By the way, the
kit price back in 1976 was $350, assembled $500.

Plain text would be even better -- please don't post RTF, HTML, or encoded
stuff to the list (or anywhere by mail, for that matter, unless you *know*
the recipient wants it that way for some specific reason. Mail is an
plain-text medium).

No, there are plenty of us here who either cannot, or do not wish to, read
HTML in mail. Quite often we just silently ignore it.

Oh come on, doncha know that anything sold on ebay *must* be extremely
rare? It's in the terms of service...
But in all honesty, in areas other than old computers, one can find some
great prices on ebay. (Do a search for auctions I've won recently and
you'll see some amazing deals on donald duck stuff. 8^)

Subject: Chat Thursday
Folks-
Do you have an old Hermes in your basement? Do you collect
ribbon tins or just like to talk about it? Have an old pinwheel
calculator? When someone says they own a dusty old PET
computer, do you find your interest perk up?
This Thursday at 9 p.m.EDT (8 p.m. Central, 6 p.m. Pacific) we will
be hosting a live chat with Jay Respler, an antique collector from
Freehold, N.J. We hope that you will take this opportunity to visit
with other people on the Internet about antique office equipment
and even not-so-old office equipment now considered antique (the
Commodor 64, for example). To enter, go to the main chat page:
http://www.asaypub.com:8080/~chatrooms
and click the mouse on the "Yesterday's Office Chat." You will be
asked for some information, such as your e-mail address. Be
there. You will likely enjoy it. Please feel free to contact me if there
are any problems getting to the chat. You will need to have frames
"on" in order for the chat to work properly. We also ask that people
observe our chat policies of being courteous, waiting for an answer
before responding, etc. Thanks.

I noticed that ( I looked a 3 Disk II's that my school had, and they all
had the grooved disc). I don't have the drive anymore (never was able to
get it to work), but All I really remember is the round cable, the red
apple (it was unusual), and the Disk II-type black front. If I remember
correctly, the case was black, too. I don't remember a data cable (at
least built on to it, like the Disk II) though. I can't remember if the
round cable was for power, and there was a plug for data, or if the round
cable was for power/data. I do remember that the plug was cut off the
round cable, though. It was about as round as a AAA battery. I think it
had five conductors.
