Hello, all:
I got a couple of IBM-labeled Tandon drives and a MPI/Control Data drive.
The Tandon drive is a standard TM100-2A and the CD drive has the following
ID#s -- Part 77711801, IBM Part# 1502060.
I'm trying to recycle these in my N* (double density setup). The jumper
area is unlabeled on these drives, as is the terminator spot. On the Tandon
drive, I found a TRW IC near the floppy connector...it has a designation
"516-3-151G"...this seems to be the terminator.
Can anyone confirm the placement of the terminator and the jumper block
pinout for both drives? Any help appreciated.

Subject: Free Computers in St. Louis: PCjr, Apple IIGS and more
I've finally come to realization that I do not need 2 (or more) of every
computer I can latch on to. I have a complete IBM PCjr system with monitor
and keyboard and several Apple IIGS systems all with keyboard, monitor and
floppy drive. I also have some CoCo 2's, TI-99/4A's, some ugly Amiga 1000's
and some C-64's. I realize these are aren't the rarest of computers but they
are still fun to tinker with and the price is right. These are free for
pickup only, I will not ship them. If you're passing through the St. Louis
area on I-70 in St. Charles drop me a line and we can arrange a meeting. If
you are able to stop by and feel like geeking out I have 300ish computers in
the basement including an Atari 1400XL with 1090XL box, Altair 8800, IMSAI
8080, PET 2001 and others that you might like to check out.

My (unexpanded) HP41c developed a strange problem...
It still knows how to do the maths, but any value stored inside a register
gets lost : i.e. 1234 STO 12, RCL 12 yields 0.000....
Any pointers ( also pointers to a more suitable group ? )

Hi Everyone,
I have thought about this topic at length...............
This is a much debated issue because microprocessors tend to have
8 and 16-bit instructions, while microcontrollers tend to have instructions
that are limited to 8-bit operands. Really, does it matter what size the
ALU is in silicon within the chip? I say no! When you are coding in
assembly
you're interested in what instructions are available to you.
For example, the Z8, 8051, 6805, PIC16, etc.. have mainly 8-bit operations
with few if any 16-bit operations. Note, please leave 16-bit jumps out of
this
discussion. The 6502 uses 8-bit operands also.
On the other hand, the 8085, Z80, and 6801 are considered 8-bitters in the
media
but they have 16-bit operations that make them more powerful than
the example micro-controllers above. Side note: Since these processors
can handle 16-bit operands with ease, pointer arithmatic is very compact.
Pointer arithmatic is very important when porting to high-level languages!
I consider the 68HC11/6809 complete 16-bitters. Why not! They both have
oodles of 16-bit operations, like the ever-useful 16-bit compare immediate!
So here is how they stack-up:
8-Bitters: 6502, 6805, Z8, 8051, PIC16, TMS370, ST6
8/16-Bitters: 8085, Z80, ST7
16-Bitters: 68HC11, 6809, 8088/8086, 65816, 80C166, ST9
16/32-Bitters: 68000, Z8000, 80286
32-Bitters: 68020, 80386/Pentium, ARM, MIPS, NS32000

It was actually pretty interesting. I didn't expect to enjoy it being as
I'm not a history buff (and slept thru most of my history classes). But
my wife's grandfather served in WWII and was part of "Omaha Beach" (I'm
pretty sure that was the one), so she really wanted to go. I found it to
be far better than I expected, and am actually glad I went.
It isn't very big, but there are a bunch of videos you can watch, and a
TON of stuff to read. You can be in and out in an hour if you want, or 6
hours if you take your time. I think I was in there for about 3 or 4
hours myself.

I have several items free for pickup in the Dallas area:
Amiga 2000 with some type of accelerator board and a tape drive, mouse
and keyboard; powers up and run's looks like it's running 3.1
Amiga 500 with an accelerator board; untested
Amiga 500; untested
A ton of Amiga software, a lot of games and a lot of programming tools
some Amiga hardware, spare accel board, zorro breakout card, modem, some
cables, 2 Commodore-Amiga monitors
A Tandy 2000, keyboard, VM-1 monitor; powers up but I
Tandy DWP printer with print wheel
Calcomp 1043GT E size plotter and a couple of hundred pens, works but
too much room
Numonics 2200 E size digitizer with power supply and puck, again want to
keep it but too much room
All are free for pickup. I live in Rockwall (20 minutes from downtown
Dallas) or I would take them to my office near Baylor hospital. I won't
ship; it I was going to ship, I'd sell it on ebay.
If it's not picked up by 3/16 or arrangements made for pickup, it's
going on the curb for the landfill.

>Except the dumpster is private property. Theft pure and simple, in the eyes

I'm not a lawyer, but this might be a regional opinion. I know the cops
around here at least don't consider it private property unless A: the
owner of the land chooses to press charges, or B: the property is some
how restricted access or not normally public access.
So for example, the dumpster I raided the other day, it was in the
parking lot of a publically accessable and open building (a gym, a
realtor, and a weight clinic), so the police wouldn't consider that
private property unless the owner of the land (unlikely to be any of the
tenants) choose to press tresspassing charges.
But, the dumpster behind the local good will, probably WOULD be
considered that by the police, because it is in the back parking lot of
the building (which is not open for customer parking, its only available
to the public when they are dropping things off), AND, the entire lot is
chained off when the store is closed.
And of course curbside garbage is always open season around here. The
only time the cops hassle you on that is if you make a mess. But good
garbage pickers always make sure they clean up after themselves.

Hello,
I got your name when I googled for ³Outbound Systems². I have an Outbound
Laptop serial# 26700007 that was traded to me by Outbound when I produced
their first Œhow-to² video on swapping the ROM.
I¹m getting ready to move to the boat and take off and need to trade the
computer for $. It is missing the cable that connects it to drive
peripherals. It has a unique connector I¹ve never seen and I can¹t find
anyone who knows where to find it. I have an external disk drive and the
SCSI box. It must have the silicon drive because it needs a disk to boot.
Any advice on finding the cable and where best to offer it all for sale?
Thanks for your time.

Hi,
Recently bought an 11/04 on epay, seems to be in fairly good shape, it has
one mass storage card in it, and it's one I'm not familiar with. Quad
Unibus, bright green PCB, made by SMS, model FD1100I. A single ribbon cable,
which seems to be identical to a modern 3.5" floppy drive cable, except it's
keyed differently - a 'corner' pinhole is filled.
Boot ROMs on the M9312 are hand lettered E35-4325 (ROM 1) and E33-4325 (ROM
2). It boots into an apparently standard console emulator.
Any clues? The 'FD' part number and the fact that it *looks* like a floppy
disk cable might be a bit... obvious! :-)

I don't know enough about electronics to understand how the power supply

There are Eight pins, not 6: (Piss poor ASCII arrangement on left, my pin

Hmm... And which "Texas" might that be? Sure isn't here...
Most of the Salvation Army, Good Will and other similar stores in San
Antonio tend to throw away computers and parts. But, you never know when
that's going to happen, so ya gotta dive their dumpsters daily. Often, all
you come away with is the stench. (Why do they always seem to park these
places next to Class-D or 1-star restaurants?!)
On the other hand, local pawn shops seem to do a booming business in
computers -- and they target an audience of suckers - i.e.: if you want an
old 386 or 486 machine, they're available -- if you have no clue about
computers, and want to pay similar prices to a new Gateway or HP!! It
doesn't make much sense, and a lot of working classic systems just sit
around collecting dust, but getting a pawn owner or manager off-center and
into reality is an absolute b-tch! '...shows ya how much the
'rank-and-file' really know about computers down here...

If you are VERY familiar with your home city, you can also scout out
the garage sales in communities which were "new" in the 1970s
I see things like Mattel Intellivison's, original Apple II systems and
such but they always seem to appear in areas which were newly built
in the early 1970s. My wife and I attend garage sales all through
our city, but only certain neighbourhoods seem to have the classic
computers.

The 4331 is (in my opinion) eventualy the single most desirable
classic /370 Machine for a proivate collector. It's reasonable
compact, but got all the bells and whistles of a real IBM of the
early '80s. Ok, the odd I/O chanels are a minus, but beside that
it can't co better for the spacewise challenged amon us.
It looks almost as if he thinks he may still get money, but he
might learn soon that he should be happy if someone is willing
to pick it up without having him to pay for that service.

The RQM Systems Power-Start boot loader board has 16 'load address' switches
(set to C000h), 8 'sense' switches, and 8 each called 'IN 376', 'IN 375',
and 'IN 374' (obviously octal representation). There is a 'Board Enable'
paddle switch on the right, tons of basic TTL and a 74S472 PROM (512x8 bits)
with room for one more.
Probably loads the disk controller start code...

Good point.

position...
Using your idea, it looks like the two missing chips
are the 6809 and the 6883 (which would make sense, as
Bob sold those as spare parts).
But, I don't think it would be a good idea to put the
wrong one in the wrong place, and I still need a set

>Apple //gs - $20 each
Wanna buy some from me?!? At that price I'll be happy to sell you a few.
>Apple //c new in box - $50
If it is really new in box, then yeah, I could agree with that price. But
I have seen MANY things claimed as "new in box" that are really "we used
it for 12 years, and before throwing it out realized we still had the old
box so we repacked it". I have seen very few really new in box items, so
I am sceptical to those claims.
>Mac Plus - $5
>Monitors - $5 each
>Misc. drives - $10
>"scads of software and manuals" - I'm assuming "scads" is worth about $25
I consider all of the above to be "Thanks" prices. ie: they really aren't
worth anything, but you feel compelled to give the person something for
being nice enough to save you the effort of digging thru the trash to get
it.
In my opinion, Thanks prices don't really add up. Kind of like coupon
actual value prices. Its worth $1.00 during the transaction, but if you
add the value up, you find it is worth half a cent. So 10 monitors @ $5
each would not equal $50, but rather maybe $10 if you were feeling good.
>Including a "new in the box" //c and "scads" of software? That's what I
>would value most in the lot mentioned.
Got about 3 moving boxes full of assorted software just a few months ago.
All that was headed to the dumpster (I intercepted it on the way). About
half Mac, half PC. I also got 2 paper case boxes of IIgs software not
much before that, probably 20 or so titles, most in their boxes. All free.

I went under the assumption that it could refer to Mac monitors and hard
drives since there are Macs included in the list. Actually, now that I
think of it, if we are talking about Apple II hard drives (regardless of
size), then those are worth something as they are much tougher to find.

Yes, we differ here. You fit into the exclusion that I mentioned. That
is, you care about having real copies of software. So to YOU the software
might be worth something. There are lots of people like me that could
care less about original copies, vs getting an "abondonware" copy off an
FTP site or so. To people like me, software is of no real $$ value.
What's interesting here is I see your point with your pricing. You
consider some items to be of value, that I don't. And vice versa (I find
some value in a Woz IIgs). So it just goes to show, when pricing things,
you can't rely on one source for info, and you should shop around to
figure out the best place to market stuff. Maybe this is why eBay prices
are always so high... with the wide audience, they increase the odds of
hitting someone that lays value on the item.
And I'm still amazed that you would give a decent price. I had thought of
you as a person that will always claim things are worth far less than
they are just to keep prices down. I miss judged you... it must just
really be a pure hatred of eBay instead. :-)

($10-$20 for 386/486 boxes, $5-$20 for monitors), but any laptop _starts_ at
$50, even XT or AT-class ones. A marginally useable 486 will most likely be
$150. I usually don't even bother with the hardware -- I go looking for old
MS-DOS software.

Well, I finally got around to testing the PSU on my 11/34. I measured at the
backplane connectors with no backplanes plugged in. Everything checks out
except for the -5V and +20V. Accordingly, the LED at the bottom of the H745
brick (regulator 1) does not light. However, some of the other voltages
coming from the H745 (according to the BA11-K FMPS) seem to be OK.
Does anything in the machine even need -5V or +20V? If not, can I leave the
bad brick in place? I have: KD11-EA, KY11-LB, DL11-W, MS11-JP, M7850 parity,
DZ11-A, RK11-D. I'll be adding a RX11 at some point. Someone enlighten me,
please. :-)
I'm pretty sure I have a spare brick.
Also: what are these signals on the 6-pin backplane mate-n-locks?
- AC LO
- DC LO
Something I learned: If you have a H785 brick in your 11/34 BA11-KA cabinet,
ignore what the 11/34 and KY11-LB manuals say about battery backup and the
rotary power switch. You can indeed have a battery backup with a BA11-K, and
the switch on the KY11-LB works as you think it should. You must connect the
ribbon cable from the H785 to the corresponding connector on the KY11-LB, or
the H785 won't work. You must NOT connect the one-wire connector from the
H785 to P4(?) of the AC input box, or else your machine won't turn off,
regardless of the rotary switch. Clear as mud?

Hi all,
I'm trying to track down a 387 math coprocessor IC for an old 386-based
Linux box that's going to be doing a bit of numbercrunching for me. Has
anyone here got an AMD or Intel (AMD preferred) 387 coprocessor rated at
40MHz (-40 part number suffix) that would work correctly with an AMD
Am386DX-40? No, before you ask, the 386DX does *not* have a built in
mathco - the 486DX was (IIRC) the first DX-series chip with a built-in
coprocessor.
Thanks.

Hi all, I have put my Intel MDS system on hold while I await
some hardware information in the mail. I am resurrecting the
second half of my project which is to get a Northstar system
up and running so I can develop the ISIS-II code again. The problem
I have at the moment is that I need the schematics for the MDC-A4
controller. I have two manuals on the double density controller
but nothing on the one I am using. Does anyone have the manual
available with troubleshooting info or at least the schematics.
I am more than willing to scan docs I have in trade.
I am off troubleshooting the controller because it will not write
properly. I can load a fresh copy of DOS, customize the I/O and
actually run DOS now, but I can't update and make a new copy
because of the write issue.
I did manage to fix an Applied Microsystems EM180B Z80B emulator
today so I could enter the console code and run things.
Thanks!
best regards, Steve Thatcher
I am curious if anyone ever had one of the Legacy Enhanced Floppy Controllers for the PCjr, was ever able to duplicate one, or know if it was ever possible to modify the current controller to take on a 1.44mb capacity.
I have a Racore unit with a modified 3.5" 1.44mb drive that acts as 720kb, and is fantastic, but would love that extra storage space if available!

oops!
Guess that was wrong.
I can remember using a Tandy Controller on a Dragon 32
once. But, I guess that one had hacked Coco ROMS.
That might be what I do with this unit, hack a set
Coco ROMS to go into it, just to get it working again.
With a new unit at $35.00, it might not make much
sense to try to get this one working again.
My Coco III is also dead. Green box with no text. I
think the 6809 is bad. At least, that's what I've been
told about these units. So, I'd have to desolder it
and put another one in just to diagnose it.
I may do that some weekend when I feel adventurous.
Suddenly caught the old computer bug....

Is anybody here familar with this stuff? I picked up a HP disk drive with the ChemStation software installed and I'd like to know more about exactly what kind of computer it was SUPPOSED to be used with. I searched the net and one site mentioned that it used a HP 9000 300 but that's all I've been able to find out. I got the Sw working on a HP 9000 217 but I'm having some problems with the display. Oddly enough, the SW won't run on my HP 9000 320 or 380!

Did you see the auction? As you say, it never made it to the online catalogue...
Also, the plotter I'm on about has definitely been saved now. He's possibly going to give it to his son's school, possible eBay it, or possibly sell it to one of you lot for ?pittance, provided you take it away (from Norfolk).
Personally, I don't need/want it, and have no means of transporting it anyway, but the offer is there for the taking.
I've decided to try to get my Dragon 64 running again.
I got it from Bob Rosen of Spectrum Projects. He
stripped all the socketed chips from it, however.
So I need to find a set of Dragon 64 ROMS, and
identify what chips go in U19 and U15.
I'm pretty sure that the one closest to the ROMS is
the 6809E, but not sure of what the other chip should
be.
What makes this more difficult is that this is not a
British Dragon. This is an American one made by Tano
Corporation.
I wish I had just offered him some money for the
original chips way back when...
I can buy a whole new Dragon for $35.00 + S/H, and if
I can't get a set of ROMS and the missing chip cheaper
than that.. I may just do that and keep this one as a
spare...
I wish I still had the Dragon disk controller also...
I know I can use a Tandy Controller, but I think I'll
need a different Disk Basic ROM for it. If anyone can
help with that, I'd be obliged...
Regards,
Al Hartman
P.S.: On the Apple II pricing discussion in a
different thread. I agree with Sellam re the pricing.
The buyer could easily resell the items he didn't want
on eBay and get the prices that Sellam quoted.
And who knows if those IIGS's contain RAM boards or
even Super SCSI cards that would be work $15.00 for
the RAM card, and $40 and up for the SCSI cards.

>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.

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
the stuff. If it doesn't look like a modern WinTel box, they don't seem

>$100 is fair.
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.

The HP 9127 is a HP-IB 5 1/4" floppy drive and normally it reads and writes a LIF format but there's supposed to be a way to have it read and write disks in a MS-DOS compatible mode. Does anyone know how to do it? I've been playing with different formatting options but so far I haven't found the right one.

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.

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.

I'm not up on what is considered a good deal for old Apple hardware, but I
have a guy offering me the following and I'm wondering what I should be
considering. I haven't personally seen the stuff yet so I don't have all the
specifics, but he says it is all in good condition, running, yadda yadda "you
won't be disappointed."
2 Apple II GS, a IIc (claimed to be new in box), a Mac Plus, couple monitors,
external floppy and hard drives and "scads of software and manuals".
Sorry I can't be more precise at the moment, but maybe if I could get some
ballpark figures....
Thanks,

I know the disk would fit, and I know it can talk SCSI, but I
didn't know whether the SCSI cabling for the disk would fit
inside the VS2000 box... That's all I meant.

Over in the Yahoo Group for the Cosmac Elf, a few of us have picked up
these MSI/88 barcode "terminals" for a couple of bucks surplus. Mine
arrived yesterday. They are interesting because they are hand-held
1802 devices with a serial port and either an LED or LCD text display
(all of mine are the LED model). I'm trying to assist in the reverse
engineering and can *not* find any data on the LED display itself, a
MAN2815, nor one of the chips that seems to be driving it, a National
DS8867.
I have googled for an hour looking for them. No results.
Anybody heard of these parts?

I have an existing 11/73 in a BA23 mounted in an H9644 cabinet (I believe
this is called "low boy"?), effectively a 19" rack/cabinet. I would like
to mount another BA23 for a MicroVAX II in the same cabinet. I have the
uVAX but no rails for it.
Any suggestion where to find these? Or what acceptable alternatives might
exist?
Thanks,
John

I have also experienced one of those construction equipment pieces, with a

Scrapyards. The boards go bye-bye first, but the racks and mounting

Hi All,
Thanks to Glen I now have info on my A&J Microdrive. On another
note, I have just received in today a Stringy floppy for the Commodore
64. This unit is brand new and has a brand new tape. It connects up
to the cassette port. Though I won't have time to test the units (the
wife calls it play) until thursday, at which time I will declare it
"Stringy Floppy day".
Anyway, anyone have experience with a stringy floppy for a
commodore? It's called a "Quick Data Drive".
Thanks

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>.

Eltec Elektronik Eurocom 1 inkl. Geh?use, Handb?cher, Ascii Tastatur,
"Grafikkarte" und Anschlusskabel.
Manche werden das Teil noch kennen, es wurde als Lerncomputer verwendet und
in sehr geringer St?ckzahl produziert. Eine f?r
Computerverh?ltnisse wirklich antike Rarit?t ! Neben dem hervorragend
gefertigten Geh?use und diversen Anschlusskabeln sind
noch 3 Handb?cher (Reproduktionen) inkl. Trainingsunterlagen vorhanden. Das
System war normalerweise nur als lose Platine
erh?ltlich und dazu gab es noch verschiedene "Zubeh?rplatinen", ein
Netzteil, die ASCII Tastatur u.a. - hier wird alles komplett und
zusammengebaut angeboten. Ger?t wurde mangels eines speziellen Netzkabels
(kleine 2 Pol Buchse) und entsprechenden
Kenntnissen nicht getestet. Verk?ufer versicherte mir allerdings, da? das
Ger?t tadellos funktioniert. Trotzdem keine Garantie auf
Funktion. Anschlie?end noch ein paar Daten aus dem Netz :
Just resurrected my Intel iUP201 Universal Programmer,
and am writing the control software for it (which will be
available for free).
I'm wondering if anyone out there has any modules for it
that they want to get rid of? I currently have the
2708/2716/2732...27128 module and the 27128/27256 module.
I've also upgraded the RAM memory on the programmer.
I'm in Ottawa/Ontario/Canada, but will pay shipping worldwide.
These things are pretty light.
Thanks,

Could you let us know in the future when you will be on? I still
haven't caught your most recent appearance... (If you did let
people know, then I guess I missed it).

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.

Hello David...
While searching for the WD-1002-05 hard disk controller on Google, I read a recent post which indicated that you may have some of these cards available.
If so, I'd like to obtain one or more of these cards.
Could you please provide any information with regard to the availability / cost of these cards?
Thank you

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.

A neighbor gave me a keyboard for a TRS-80 Model II, but I don't have the
rest of the beast, so this item is available to he or she with the best sob
story for the cost of shipping. Keyboard is a bit dirty (as would be
expected from lengthy storage in a clean basement), no major blemishes, all
key caps in place, none sticks/good feel. I do not know if it is working
otherwise, and have no facility to test. Please reply off-list to patrick
at evocative dot com.
