I've been cleaning out my storage shed and getting rid of some the HP equipment that I still have around. I just listed a HP 9000 220 computer, a 9000 217 computer, a HP 9133B hard drive with HP BASIC Version 5 and HP 8753 network analyzer software installed and a HP 9122 C floppy drive on E-bay. All working and in good condition. See <http://cgi6.ebay.com/ws/eBayISAPI.dll?ViewSellersOtherItems&userid=rigdonj>.

>Hoping to find a PCjr show up here is probably impossible.
I thought I offered the PCjr to the list when I saw it there. No one
responded, although the price they were asking seemed steep. $12.50 IIRC,
for JUST the PCjr. No power brick, no keyboard, no monitor. Although it
did have the parallel port sidecar.
Alas, I only have one PCjr left myself, and I'm hanging on to that one. I
had 50 or so a number of years ago, but they were all donated to a local
school system. I might have an extra monitor left however, but I'm not
sure. I should still have some PCjr video to CGA pigtails, but they are
all home made (not by me, but by another employee here), and I think
someone on this list posted the pinouts for such an adaptor some time
back.

Hi all,
unfortunatelly one of my two RD54 hd (by Maxtor) in my mvaxII kept doing
strange sounds at startup. It isn't coming on line as before, now it takes a
lot of time while a continuous noisy sound comes from it, and after it seems
sufferig of read problems at bootup.
Any info/advices about RD54 and it's strange sounds will be greatly
appreciated.

Yeah, that's what the one near me does. They won't even take them in
anymore. What's worse is, they will take all the parts... just not the
CPU. So they breakdown otherwise complete systems.
Although, I am humored when the occasional computer makes it thru, like
the other day they had a PCjr. It just shows that they know nothing about

WOW! I can't believe Sellam of all people over priced this bundle.
$100 is very generous for what is listed. Unless there are some really
unusual monitors or software/manuals, then I don't think the lot is worth
more than about $20, and that is more as a "thanks for letting me have
it" gesture.
I have aquired everything mentioned above (catagorically, obviously I
don't have specifics on the monitors, drives, software, manuals), from
the curbside garbage in the last six months.
There could be things that bump the value up a bit. Such as the IIc being
truely brand new never opened (and not just clean and reboxed). If the
IIgs are Rom 0 units (or Woz units), and if the monitors or hard drives
are large (20" monitors, and 10+ gig drives). The software and manuals,
unless it is current release stuff, exotic hard to find stuff, or things
you care about owning real copies of (vs abondonware copies), then it is
of little value.
Bear in mind, even if there are parts that pump up the value, you need to
overcome the $20 "thank you" price first, so you start at $0 and go up,
not start at $20 and go up.

the old plasma screen (which was badly burned in and faded) just before I
quit using it. It also has a removable "backpack" on it with two ISA card
slots for network cards or whatever. First come, first served.

It probably means you have one of the ones with an incandescant bulb,
not an LED, and the bulb has burnt out. That's a common problem, and
easy to fix by replacing the bulb with an LED and dropper resistor.

I've managed to find the pieces (or at least the most important, which is
one of my two RD54's) to do some performance testing on Doc's recent idea
of using a network disk instead of a local disk to get better performance
than a RQDX3/RD54 combo offers.
As a result I'm trying to get either a VAXstation 4000/60 or /90 setup so
that I can use it as the host. In doing this I ran into a slight problem
with VAX/VMS V5.5-2, it doesn't like my 3rd party SCSI disks that I've got
in the /90. Not a big problem as I've got some brand new (!) RZ25's that I
can put into one of the systems, and I want to put a RRD42 into one of them
as well.
Stupid question, how to I go about getting the cover off of the 5 1/4" bay,
and am I supposed to have another piece of plastic to go there? If it
requires another piece of plastic (that I don't have), I'll just hook the
drive up internally long enough to do the install.
Now to decide which system gets a V5.5-2 install, I'll probably go with the
/90 as it's my fastest VAX, and will therefore be the best for building
software on.

Has anyone managed to find drivers for the DaynaFile?
I have a couple I'd like to experiment with. One non-functional,
unfortunately, but I pulled the rom on it to image it and
attempt a disassembly. I have another that appears to work,
or at least responds to a scsi inquiry. I plan to hook
it up to a logic analyzer to get a memory map of the board.
The logic boards on the two I have are simple, with common
parts in clip-friendly 40-pin dip packages:
scsi: DP5380
floppy: WD2793
micro: 8031
Documentation is available for all of these, so a person could
potentially write new firmware. Probably much easier than
disassembling the rom.
I remember using a DaynaFile on a NeXT cube with an old (ca.1990?)
version of Nextstep, so there are potentially Nextstep drivers
out there as well.

Eric Josephson
Barry,
didn't you ask (under the pseudonym of Fred Feuerstein) for a
description of the switches on a DS120 Terminal Controller?
I managed to find a user manual from the stone age, stating that the
"Logic Card" is part number 512000-2. Not quite the 5120000-1 that you
mention in your posting, but possibly close enough to provide hints for
what functions might be there. YMMV...
This is what the manual says about the DIP switches:
SWITCH FUNCTION
1 Carriage motor disable (test only)
* 2 Reverse channel override
* 3 FDX/HDX override
* 4 Local Auto-LF override
** 5 Parity odd (ON) parity even (ON)
** 6 Parity enable (ON) parity disable (OFF)
7 AUTO-LF from line (ON) disable (OFF)
** 8 X-on, X-off handshaking enable (ON) disable (OFF)
* On DECwriter models with the 8-key control pad, these switches are
duplicated on the keyboard. Those models with the 3 rocker-switch
panel must control these features with the DIP-switches.
** See Appendix B, "Additional User Information", for a functional
description of these switches.
End of cite. Appendix B talks a lot about half-duplex modes, which I
presume will not be used with your PDP-11. Hence, you will want to have
switches 2 & 3 in the OFF position.
The description of switch 5 obviously contains an error. For even
parity, the switch needs to be in the OFF position (says appendix B).
Another noteworthy cite: "If parity is disabled by DIPswitch #6 "OFF",
then DIPswitch #5 provides 8th bit spacing when "ON" and 8th bit marking
when "OFF"."
In other words, you actually cannot select "no parity", but you can set
"mark" or "space" parity.
You report having trouble with the 20mA interface. Maybe you need to
switch from active to passive or vice versa? - Here's what the manual
has about it:
3.1.3 20 MA CURRENT LOOP
A 20mA current loop interface is provided featuring a photo isolated
receiver and transmitter. The receiver and transmitter may be configured
to operate in either passive or active mode. Unless otherwise specified
at the time of purchase, the DS120 comes configured with a passive
transmitter and receiver. Although specified at 20 mA, the signal line
currents flowing in the receiver loop may be as high as 80 mA without
harming the interface. Any current in excess of 15 mA will be
interpreted as a mark, and any current under 3 mA is interpreted as a
space. 1500 volts of isolation is provided by the photo isolater if
passive is employed.
The jumper configuration for the current loop interface is as follows:
W1 W2 W3 W4 W5 W6 W7 W8 W13 W14
-------------------------------------------------------------------
PASSIVE Out In In In In Out Out Out Out Out
ACTIVE In Out Out Out Out In In In In In
The connections for this interface are as follows:
PIN 2: Transmit -
3: Receive -
5: Transmit +
7: Receive +
End of cite. Hope this helps.
If you need more information, I can get whatever is printed in the
manual for you. I do have a LA36, but it features the original DEC
controller board, so I have no way of actually trying anything.

Since I haven't seen any other responses, I'll dive in... This is
all speculation - I'd love to have someone with a line into DEC
Engineering answer this properly. To put it another way, I may be
completely off my rocker - reader beware! ;^)
The VAXstation/MicroVAX 2000 was released in 1985 (cf. R.D. Davis'
uVAX FAQ), which means development and planning may have started
as early as 1983 - I'm just guessing here.
In the early 80s large (> 20MB) ST-506 hard drives were still
hugely expensive beasts. If you did find a native SCSI device, I
imagine the costs would be much higher for the extra interface logic
on the drive. Without native SCSI on the device, you needed a
translator like the Adaptec ACB-4000 (SCSI/ST-506) or Emulex MT-02
(SCSI/QIC-02).
The base VS2000 was a pretty small box - perhaps even ground-
breaking for this timeframe, given it could run full 32-bit uVMS
or Ultrix and had internal storage, unlike the Sun-2/50. Having to
develop and wedge in a unique converter board may have been riskier
than adapting a version of a board you were already producing/
designing for the other uVAX models like the RQDX3.
Going back to that comparison to the Sun-2/50 may answer the question
of why SCSI was acceptable for the tape interface. Since the tape
drive was going to be external, there's plenty of room for that extra
logic board. And it's only a tape drive, so if we can't get decent
throughput out of our first (?) SCSI interface, well, who's going to
notice when the tape drive is as slow as the TK50? ;^)
After a few years of Apple, Sun, and others driving SCSI into the
marketplace the whole picture changed and by the time the first pizza
box workstations come out everything is SCSI.
Anyway, that's my best shot at an explanation. Again, I'd love to
hear from someone who was inside DEC (Megan?)...

Yes :-) The MAN series used to be popular but I'm afraid I don't have
any data. However, I do have a data sheet for the DS8867 -- it gets a
page-and-a-bit in the 1980 Nat Semi Interface Data Book:
DS8867 is an 18-pin DIP 8-segment constant-current driver, designed to
be driven from MOS circuits operateing at 8V +/-10% minimum, and will
supply 14mA typical current to an LED display. Output current is not
sensitive to Vcc variations.
Features:
internal current control - no external resistors
100% efficient - no standby power
operates in 3- and 4-cell battery systems
inputs and outputs grouped for easy PC placement
Absolute maximum ratings:
Vcc 7V
input voltage 10V
output voltage 10V
Operating conditions:
Vcc min 3.3V max 6.0V
ambient temperature min 0deg C max 70deg C
logical '1' input typ 4.9V max 5.4V
logical '0' input typ 0.1uA max 10uA
logical '1' output min -8mA typ -14mA max -18mA
logical '0' output typ -0.5uA max -10uA
Pinout is straightforward, pins 1..8 are inputs 1..8, pin 9 is ground,
pins 10..17 are outputs 8..1 (ie the outputs are almost opposite the
inputs), pin 18 is Vcc.

RT absolutely needs block 1, the Home Block. If you want the
disk bootable, then 2-5 are absolutely required. Typically,
blocks 6 through 6+(2*31)-1 are required for the directory,
but the home block contains a value where the directory is
supposed to start... but I don't believe that RT actually
uses this field, and many utilities certainly don't, assuming
the directory starts in block 6 (not to mention user programs).

I don't know how many people might be interested, but I have finally
been successful in creating a Bootable RT-11 CD which also has
the standard ISO file structure. However, the really key point is
that none of the files on the CD are duplicated.
On the other hand, I am unable to test the CD that I just burned
using real DEC PDP-11 hardware since I have never tried very
hard to find and successfully test a CD-ROM drive with a SCSI
host adapter on the Qbus PDP-11 which is available for such
purposes. But, using the Full Commercial Ersatz-11 running
under Windows 98 SE, I just did the commands:
MOUNT DU0: SCSI0:
BOOT DU0:
I assume that if I had a suitable real DEC PDP-11 system with
a SCSI CD-ROM drive, the exercise would work there as well
since I know that others have been successful with an RT-11
ONLY CD that boots on real DEC PDP-11 hardware.
Since many of you reading this who don't know much about RT-11
will likely be confused, let me describe very briefly how I started.
I first took 4 RT-11 RL02 bootable images or DSK files, each being
20450 blocks long. Since only the first 5000 to 6000 blocks of each
file contained useful non-zero information, I reduced each image to the
size that did not contain any blocks with all zeros so that all 4 RL02
images would fit into a single RT-11 partitions of 65536 blocks. I
then
used Nero Burning under Windows 98 SE to copy all 4 RL02 images
to a CD which had the standard ISO file structure after which I copied
24612 blocks from the CD-RW to a file under Windows 98 SE:
Blocks 0 to 63 - All zeros
Blocks 64 to 99 - Standard ISO file structure
Blocks 100 to 24599 - The 4 files
Blocks 24600 to 24603 - Extra information for the standard ISO file
structure
Blocks 24604 to 24611 - All zeros
The first file from block 100 to block 5192 was the RL02 bootable
image for V5.03 of RT-11.
There is one technical problem I have not solved - the current
test was done with a CD with an image that is identical to a
file of 24612 decimal blocks - which is less than one full RT-11
partition. If I am going to be able to use a CD with more than
65536 decimal blocks of files (i.e. more than one full RT-11
partition), I will have to solve one critical problem. I must find
a method of preventing any files under the standard ISO file
structure from using any CD sectors that fall in the first 16 that
start on a multiple of 16384 sectors (of 2048 bytes which is
how a CD is written for those users who might not know).
These number correspond to the first 64 blocks that start on
a multiple of 65536 blocks (of 512 bytes) on a hard disk drive
which corresponds to each RT-11 partition.
Before I describe the details, note that the method is probably
useful ONLY when the CD contains a limited number of large
files. This is because the RT-11 directory on the CD must be
mostly constructed by hand at the present time.
The first step is to create an exact copy of a CD which has been
burned with the desired DSK files. This image file can be
created using PUTR to specify the exact size plus E11 and RT-11
to copy all the blocks from the CD to the image file.
The critical reason that everything works seems to be a rather
fortunate use of the mutually exclusive areas by the RT-11 file
structure and the standard ISO file structure. While RT-11
requires the first 64 blocks (of 512 bytes) for the boot blocks
and file structure, the standard ISO file structure uses the next
9 sectors from sector 16 to sector 24 (of 2048 bytes) which
allows the RT-11 DSK files to start at block number 100 or
sector number 25. All that is required (from the RT-11 file
structure for the RT-11 DSK file that is in the first RT-11
partition) is to copy the RT-11 file structure (ONLY - i.e. just
blocks zero to where the directory segments stop) to the start
of the image file (which is initially identical to the ISO file
structure CD image with the DSK files placed on the CD
using standard CD burning software - in my case I used
Nero Burning on a CD-RW so that I need not toss the CD).
I produced that image file by using E11 and RT-11 to copy
the CD-RW image to an existing file under Windows 98 SE.
In my test, since I chose the first DSK file which started at
block 100, the next step was to add 100 to the starting block
number in each directory segment. The final step was to then
select the monitor that I wanted to boot and write the correct
boot programs into block zero and 2 through 5 of the image
file. All of the extra steps were easily accomplished using
E11 and RT-11.
The following summary probably helps:
RT-11 file structure: Blocks 0 to 63, Sectors 0 to 15
ISO file structure: Blocks 64 to 99, Sectors 16 to 24
RT-11 files: Blocks 100 to 65535 for partition zero
ISO files: Sectors 25 to end of CD
To create an RT-11 bootable CD, I copied the original CD
image to a Windows 98 SE file on the hard disk. I then copied
did an INIT DU0:/VOLUME under RT-11 after which is copied
blocks 106, 107, 108, 109, 110 and 111 to blocks 6,7,8,9,10,11.
The SIPP was used to add 100 (144 octal) to the fifth word in
blocks 6, 8 and 10. The last step was to use the RT-11 command
COPY/BOOT DU0:RT11XM.SYS DU0:
I then had to use the "Burn Image" option under Nero Burning to
transfer the complete file back to the CD (after I had erased the files
of course) since I do not have any software to write just the first
3 CD sectors.
One other aspect is also permitted under RT-11. Since every
RT-11 directory segment contains the starting block number
in the fifth word, it is possible to have the ISO file that is a
bootable RT-11 image of some device referenced both by
each file AND as a single DSK file starting with a new directory
segment at the end of all the individual files. In my actual test
example, there were FOUR bootable DSK files under the ISO
file structure (within RT-11 partition zero). The first 3 RT-11
directory segments (starting in block 6 of the CD) contained
file headers for 206 files. An additional directory segment was
then added (manually one word at a time with SIPP) which
had an empty area starting at block 100 with sufficient space
for the FOUR bootable DSK files. CREATE was then used
to set up the file headers one at a time. Obviously RT-11
is being "fooled", but it does work!
The net result is that it is possible to use the same files under
BOTH the standard ISO file structure AND the RT-11 file
structure.
While all of the above was done on a Pentium system running
Windows 98 SE, Nero Burning, Ersatz-11, PUTR and RT-11,
I am confident that other operating systems and software
utilities would also be successful. The actual concepts are
really very simple. Implementation of the test case did take
almost a week since I made a lot of mistakes along the way.
But at this point, I could duplicate a second test in a few hours.
If there are any questions, I will be glad to answer them.
I do have one request. Does anyone know how or if it might be
possible to write a program that can take the image of the CD
after it is copied to a file on the hard disk and copy all the data
to a second slightly bigger file. The key requirement would be
that the blocks at multiples of 65536 (where RT-11 partitions
start - actually 64 blocks in each of the 20 possible RT-11
partitions) would be left empty. I would imagine that a simple
FORTRAN program could do this if the ISO file structure is
known since all that would be required would be to change
those parameters which specify the sector number where the
file starts - AND move the associated file up in the CD image
in the destination file so that 16 sectors starting at multiples of
16384 sectors are left empty.
Sincerely yours,
Jerome Fine

Hello again,
I've got a Sinclair (well, Amstrad really, but it has Sinclair printed on
the front) monitor here, which claims to be a QL monitor. To the extent
that it has a captive QL-specific signal lead...
However, the display is too wide, and marginally extends past the bezel in
both directions; only by about 1/4 of one character or so, but just enough
to be seriously annoying.
So, today, I whizzed the back off to adjust it - but there's no "horizontal
size" pot :( There are trimpots for V.size, H.hold and Sub-bright. There's
adjusters for focus & brightness (or maybe contrast, it was hard to tell
since it was simply labelled "Screen". There's also externally accessible
controls for V.hold, brightness & contrast. On the back of the tube,
there's trimpots to adjust red & blue intensity (with two pots per colour).
It looks like there ought to be a green pot as well, but there's no trimmer
there, just a fixed resistor.
So, is it the case that I cannot adjust the h.size? Is it a case of go
rooting around looking for the component (a resistor, I assume) which sets
this, and replace it with a pot?
Any advice appreciated.

Thanks, everyone for your suggestions regarding SCSI controller for RT-11,
DECserver in Kansas City, etc. All of this is leading up to me building a
PDP-11 SOMETHING out of parts I can afford.
I've worked with Mike McFadden and he bought the rack of equipment containing
the terminal server and is selling me the CPU board;
Thanks to Jonathan telling me about the auction, I bid on and won the "LSI-11
Box Blow Out" on eBay PLUS the QBUS chassis (sold separately); Watch for me to
announce the availability of the 11/23 CPU's and other boards from this
auction. Hopefully the sale of some of these things will defray some of the
expense of the construction of the PDP-11.
I already have a pair of SSSD 8" floppy drives I bought to use with E-11 and
PUTR to copy from my PC to RT-11 RX01 floppies - now I need to buy the adapter
board from John Wilson to connect the big floppy's to my old 486.
I have a DECserver 550 with its CPU and CXA16's; I may use the chassis and the
CPU, or just the one from Mike McFadden. Then again, I have enough stuff now
that I could build two systems.
I have a RQDX3 and RX50 for a floppy interface to the prospective PDP-11. I'll
use one of the drives from the "Blow Out" in the new system. The chassis I
bought in the "Blow Out" has a foundation module with disk controller, etc. on
it, so I may not need these items.
I have 2 Ethernet controllers, the one from my original DECserver 550 and a
DEQNA I recently bought. One of these is likely to go.
It seems to me I am almost set - all I have to do is get all the stuff here
and set it up :-) that should be a SNAP - right? Lets see - ~1978 to 2003 is
how many years old this stuff is??? Only 25 or so. Should be no problem <g>.

I've got a DEC GiGi that appears to work, but has some cosmetic damage,
and is missing a few keys. The keykaps are the same style as used on the
Decwriter III, IV, and other DEC equipment. The missing keys are the 6-9
keys on the QWERTY section, PF1, PF2, and 9 on the numeric keypad.
I've hooked it up to a monitor, and it gives an output as I type on it, so
it probably works just fine.

On all the Amsturd monitors I've had the width is fixed
and can not be easily adjusted. It's not a pot or resistor
that you're looking for, it's a coil, usually about 1/2"
to 1" in diameter and with a ferrite I core. If you're
lucky it will have an adjustable core but I have yet
to see one in an Amsturd.
If you find the coil (you can tell because bringing a
metal tool up to it will change the width/centering) you
may get away with glueing a lump of ferrous or non ferrous
metal to it (one will make the picture wider and one
narrower, I can't remember which off hand). If this then
offsets the picture a small permanent magnet can be used,
on the width coil, to pull it back.
Cheers,
Lee.
