I have about half a dozen PS/2 model 55SX machines that I need to sell
or trade. They're all in excellent working condition with hard drive,
floppy drive, built in video/com/lpt/mouse ports. Can accept up to 16mb
of ram and runs a 386SX-16 processor.
These are tested and in good physical and working condition. Just add
SIMMs, keyboard, mouse and monitor. Great replacement for a flaky unit
or to add a machine for the kids. All have MS-DOS 6.2 on the hard drive.
Reference/Setup disk included.
Asking $30 each plus shipping. The Dallas realtime clock chip on the
board or even the floppy drive are worth that alone. Trades of other IBM
ISA, MCA or VLB equipment will be considered.
I also have 55SX motherboards in great condition for $10 each plus
shipping. Shipped in foam padded mailer with setup/reference disk. Just
open your dead machine and replace the board.

Cord,
Your chances of finding another battery are slim. Even if you find one
it will be old and probably won't last long. My suggestion is to take it
to one of the battery places that rebuild batteries and have them replace
the cells in your old battery. There is a place in Sanford, Florida that I
have used a lot and that I'm very happy with. Their name is TNR, I don't
have their phone number handy but you can get it from directory info. They
use good quality batteries so their batteries will usually last a lot
longer than the original ones since the OEMs usually use the cheapest junk
they can find.

Quick question, how does one make sure the heads of a RL-02 drive are
locked? I'm supposed to be picking one up this weekend (mainly for the
Q-Bus controller and diskpacks). I want to make sure I transport it
correctly since I might need it for my PDP-11/44 (still don't know the
state of it's drives.
On another note, anyone have any recommendations on where to get some RAM
boards for a /44? Once I have the packs that will be the only thing I'll
need (assuming everything works).

Maybe Tim is, but on reflection (no pun) I'm not.
The terminal acts as a buffer for the data, not for the keyboard. The
keyboard is used to make changes to the data in the buffer and
initiate the transfer of the changed data back to the 3000. The
keystrokes themselves don't get sent to the 3000, only the edited
data.

Last time I was in Sunnyvale, CA I found a pile of WordStar 3.24 distribution

There were several other copies. They're marked "CP/M-86 or MS-DOS" or
somesuch only because it's not obvious from the documentation which version
it is; the one I bought is for MS-DOS and I presume the remaining ones are

Check out Tandy's version of history from their web page:
"1977 TRS-80 Model I Personal Computer introduced.
(First mass-marketed personal computer. In contrast to
build-it-yourself computers available at the time, the TRS-80
was fully-wired and tested. Sold at a breakthrough price of
$599. More than 200,000 TRS-80 computers were sold from
1977 to 1981.)"
Ok, let's conveniently forget about the Apple ][. This is the most
blatant denial of reality and outright lie I've ever seen a company
publicly endorse.
"1980 TRS-80 Model 100 Portable Computer introduced.
(First computer ever to feature five programs and a
telephone modem built-in. Used by journalists throughout
the world.)"
First I question the year (I know it was later than 1980). This claim is
dubious at best. Mostly its broad and irrelevant. It seems they're
trying so hard to make this seem like a breakthrough (it was) that they
forgot to mention the real reasons why.
"1984 Tandy 1000 Personal Computer introduced.
(First PC-compatible personal computer. Within one year,
the Tandy 1000 became the best-selling PC-compatible
computer.)"
God, what a load of chicken turds. I think they missed this distinction
by 3 years and umpteen other companies. I'd like to kick the guy who
wrote all this crap in the nuts.

Tim's answer got part of it. Here's some more of the picture, maybe
in gorier detail than you wanted to know.
Many HP terminals are somewhat intelligent and can be told (via escape
sequence or strap setting) to operate in "block mode", where the
terminal buffers data in its local display memory and lets the user do
local editing of it there. There can also be protected and
unprotected fields, which basically turn the display into a fill-in
form where the user can type in the unprotected fields and not in the
protected fields.
Some keys (ENTER (not RETURN) and the function keys) will still
initiate a transfer to the host computer. How that works is a
collection of fiddly little details but I'm going to try to describe
it in terms of the DC1/DC2/DC1 block-mode handshake.
Once the form has been sent to the terminal by the application (which
basically sends escape sequences and text to set up the block mode, the
form, and the unprotected fields), the application starts a read. The
terminal I/O system then sends a DC1 (control-Q) to the terminal so the
terminal knows there's a read pending.
When the user presses ENTER or a function key to tell the terminal to
send the form, the terminal sends a DC2 (control-R) to the host as an
indication that there's a block of data ready for transmission. The
host does whatever it needs to do to get ready for the block (this was
important in the days of the Series II/III which used a terminal
controller that couldn't handle all 16 ports sending 2400 bps data at
the same time) and then sends another DC1 as a go-ahead, and the
terminal sends an escape sequence for the pressed key followed by the
block of data (usually the data from the unprotected fields on the
form, separated by field-separator (FS) characters, and finishing up
with a record-separator (RS) character). The terminal won't send anything
more 'til it sees another DC1 from the host.
OK, well, that's about what you see on the wire if you stick a serial
line analyzer in between the 3000 and a terminal, and watch as an
application written using one of the more popular block-mode
application subroutine libraries (VIEW aka V/3000 aka VPLUS/3000) is
in use. Later 3000s have terminal controllers that can handle full
speed on all ports, and they can use a simplified block-mode handshake
(i.e. the 3000 sends the initial DC1, and the terminal just sends the
block when the user presses ENTER or a function key).
The goal of all this was, as Tim said, getting a rather slow HP3000 to
run a surprisingly big bunch of terminals doing transactions against
data on the 3000. The 3000 didn't have to do any work for the user
until the user had the transaction edited on the screen, in particular
it didn't have to respond to every user keystroke, and as the terminal
didn't have anything better to do it could respond to the user's
keystrokes right away.
There were also some full-screen editors that relied on the terminal
to buffer lines of text and let you do your editing in the terminal.
Those I used tended to run in line block mode (vs. VIEW which I think
used page block mode) where once the user pressed ENTER the host would
home the cursor and start sending escape sequences ("<ESC>d" I think,
followed by a DC1 once the read was pending) to get the terminal to
send the current line 'til it got to the bottom.
Feel free to ask questions about this if you want to know more.

Wordstar on the Otrona Attache was also very WYSIWYG because the Otrona
could do any video attribute Wordstar every dreamed of: italics, underline,

Hi,
I've not participated much since I joined this mail group
a number of weeks back, so I thought I'd make myself heard.
A few of you seem to be pretty familiar with HP equipment
so maybe you can tell me what I have (or have not) here.
I pick up a box of junk at the local recycler several
weeks ago. It caught my eye because it has some microprocessor
emulator pods. In the box were the following:
Z8002 emulation pod, HP part # 64233A (says use with 64271A)
Z80 emulation pod, HP part # 64252A (says use with 64251A)
6801/6803 pod, HP part # 64256A (says use with 64255A)
also the following boards:
64300/66501 internal analysis bd
64154/66501 Static Ram board (only one of 4 rows has sockets installed)
64152/66501 Static Ram board (All 4 rows socketed and populated)
[both of the above have 2147 memory chips]
64211/66501 680x Control board
I called HP and asked what the pod normally connect to, just in
case it was still down at the surplus store and I had overlooked it.
HP says that they would normally be used with a "frame" (?) i.e.
some sort of general purpose analyzer having a part number of
29000 or 29120 (these two number are from memory since I can't
find my notes at the moment where I wrote down the two numbers.
It was either 29000 or 59000 but I'm pretty sure it was 29000).
I was attracted to the emualtion pods because they looked like
they had never been used. All of the pins appeared to be straight
and intact. There was protective foam one each pod.
What can you guys tell me about these? I'm thinking that without
the frame they are not very useful to me. Perhaps they're worth
something in trade?
Thanks,
Jon

For what passes for full-screen editing, the display is pretty much
something you can type on. Cursor movements available are up, down,
left, right, page up, page down, home (top-of-buffer), and
end-of-buffer. Typing defaults to type-over but there is an
insert-char mode that you can turn on and off from the keyboard. If
you do this, wrapping is kind of simple (it will open up a new
next-line and wrap characters onto that as they go past the right
margin). Also you can delete characters from the keyboard (but this
does not un-wrap wrapped characters). It's also possible to delete
lines and add blank lines, and clear to end-of-display. Not
cut-and-paste, though; well, if you can use the memory lock feature
of the terminal you might be able to do it but some of the full-screen
editors used it in a way such that if you tried to use it you would
screw things up and lose work.
Things are somewhat different if protected fields are set up; those
will limit character insertion and deletion.

Mind pointing me to some of those stories.
HP did something odd in the early-mid 1980s: HPWORD. This was a word
processing system for the HP3000 that used 2626W (and later, 2628A and
HP150) terminals as intelligent front-ends. When you first started
HPWORD after turning the terminal on, it would spend about 10 minutes
downloading code to the terminal, and then the downloaded code ran the
interface and the communications link back to the HPWORD process on the
3000. I was told at the time that the terminal handled processing up
to the paragraph level, and got the 3000 to do anything larger.
HPWORD was actually a little more WYSIWYG than, say, Wordstar, because
the terminal actually had bold and italic faces and underlining
features. And it was nifty because you could queue up a print job
>from one terminal to a printer connected to another HPWORD terminal;
the backing HPWORDs running on the 3000 would talk to each other and
get the document printed. Oh, and someone could be typing on the
terminal that had the printer connected.
All in all, it was a cheaper solution than PCs in the 1983-1984 time
frame when we bought into it -- we didn't have to buy a printer for
every workstation, and we didn't have to pick a PC LAN with lots of
funny cabling.

Yeah, and back then I used to switch between editors depending
on the job at hand. Some things just work better with good old
EDIT/3000, and even for editing code I liked QUAD. Later when I
went to work at Wollongong I discovered Voodoo on the 3000 there
and got kind of used to it; it tries to be vi-like but the inherent
inability of the 3000's terminal I/O to accept characters without a
pending read (and to do anything else while there is a pending read)
really got in its way sometimes.
Now I just use Emacs (though not on the 3000), and quite frankly I do
think it works better.
