This is probably off topic, but maybe only slightly. I don't know the age
of the Typewriters in question.
Does anyone need 3 unopened typewriter ribbons for an IBM/Lexmark
typewriter. I don't know which model specifically, but the ribbon is
labeled as:
IBM Easystrike Superior Write Correctable Ribbon #1380999 by Lexmark
If anyone has the typewriter these go to and wants 3 of these ribbons,
unopened, still in their box, let me know... you can have them (just pay
postage, they should be under one pound so it should be really cheap).
Also, if anyone knows what typewriter they go to, let me know. I'm
curious why I have 3 of them, and maybe if I knew what they went to I
might know why they were purchased.
They are going in the trash in the next few days, so respond quick if you
want them.

Subject: Seeking good home(s) for old hardware
Can anyone provide any suggestions, flippant or otherwise, as to where
I might seek new homes for some old kit that has been cluttering my
attic for many years? My wife is putting her foot down, and frankly I
am never going to do anything with it. I am paring down my collection
of old computers and peripherals to a few that I will actually use,
and trying to find people who will actually use the others.
So I need homes for:
* SWTPC 6809 computer. Main unit, disk unit inc. 8 1/2" Qume floppy
drive, Western digital harddisk controller but no HDD. VDU/terminal
(not working). Used to run Uniflex (but I don't have this, since the
hard disk crashed and there were no originals provided). I have all
the hardware and software manuals. I have seen this computer working
but it has been stored a long time.
* Remex paper tape reader/writer (works as far as I know, but I don't
have the cables for it).
* Diablo daisy wheel (have seen it working but about 17 years ago!)
It's a long shot, but somebody may be able to help. I can provide
more details if anyone is interested. Mail me at jpcc "at" bigfoot
"dot" com if you prefer. I am in the UK.

I used one in a XT about 1990. Great monitor. However I think the monitor is
a Wyse 700 not an 800 if you are looking for drivers. Originally with a
matching 8 bit ISA double card IIRC.
They also made a 19" 7XXX series of High res mono white monitors.

Hmm...
If they're FAT16 (2.1Gb max recognition), maybe you can get hold of an old
copy of Partition Magic, and see if you can read them with it.
Its doubtful that the drives are physically harmed, but the 0 Sector (boot
and/or reference sector) will be different with each version of DOS you try.
If you can boot from floppy, you may want to reformat the disks (DOS 2.11,
or 3.20) and start anew. Do you know what they likely contain? Are they
worth the time/effort to recover as-is?

Subject: HH drives
Hi All
I have a newbie question <collective groan from list>
I don't have much experience with HH type drives and recently unearthed
a Wyse Technologies machine at the local refuse recycling centre (it's
a shop rather than me wading though a landfill site - I'm not that
desperate).
Inside this machine (stated built in 1986) were two HH type 5.25" hard
drives (one a Segate ST-251 the other not branded but built 1989).
On boot up I get:
Pheonix 80386 ROM BIOS version 3.53
(c) 1985, 1986 Pheonix Technologies Ltd
640K Base 1408K Extended Memory
Hard Disk Failure
I have booted the system using a floppy and one drive (the unbranded
one) is partially readable.
It is a 41Mb drive split into two partitions (primary & extended) -
FAT16 system
It seems to have been installed with DRDOS.
Using my later versions of DOS on floppy I cannot get the drive to
respond to any standard commands (I always get a 'Sector not found'
error).
Can anything be done to revive these disks or were they left unparked
and now physically damaged?
I have another 5.25" hard drive displaying the same unresponsive
characteristics... are they all dead?
Thanks in advance
Alan
My first Pc was an Amdek/Wyse 10Mhz 8086. I had installed an RLL 30MB drive
in it.
We used Wyse's and PS/2 model 25's at work. I have the original hard drive
>from my Wyse and the diskettes somewhere.
I'll look

Thanks Jeff, but I took Zane's advice and found some on eBay.

My TTY *does* have a relay on the reader "powerpack" board which
can be turned on if an XON (DC3, Ctrl-Q) is sent to the typing
unit, and off again upon receipt of an XOFF (DC1, Ctrl-S); it also
latches itself on if the reader's manual start lever is flipped,
until it is pushed to the stop position, or the tape-out contact
opens. Is that the relay to which you are referring?
Are you sure the 8/e actually goes to the trouble of turning
off/on the reader after EVERY character? At 10 cps that's 100,000
uS between characters (60,000 machine cycles on my 8/L)?
Meanwhile I have my 33 apart awaiting new function levers that
trigger the above flow-control options (someone had installed
Ctrl-B and CR instead of the correct Ctrl-S and -Q). Further
reader "tuning" will thus be delayed...

The idea is to clear the IER as early as one can to make
sure that no interrupts are generated. Since IER and DVH share
the same I/O address and are selected by the MSB of the LCNTL,
I needs to clear both LCNTL and IER first. Note: the DCR A
causes the MSB to be set for the LCNTL that selects the baud
rate registers, DVL and DVH.

First, the last JMP LDR was suppose to be JMP LDR1 ( my typo ).
As long as the high part of the address of the new code to run was
the same as LDR1, by writing one byte at a time, overwriting
the same high part would not cause the JMP LDR1 to change its action.
The next byte to be over written would be the low part of the address.
when this happened, the JMP NEW would happen instead. One just need
to make sure that the start address of the NEW code has the same
high byte. In this case, I can just put it right after the JMP LDR1.
It would look something like:
Tail end of boot strap:
2328 DCX H
2329 JMP
232A 1E
232B 23
New code to run after load:
ORG 232A
DW $+2
NEW: New code starts here
.
.
.
As you can see, the two will overlap and the final JMP of
the bootstrap will be modified to point to the new code on
the last loaded value. This is why it is loaded backwards.
I should note that Patrick Rigney found one more byte to
remove. The sequence:
ANI 01
JZ LDR1
could be replaced by:
RAR
JNC LDR1

I have an "H" series drive and an Apple II specific
Omnidrive. Not 100% sure that they are still working,
as they have been in storage for over 10 years.
I also have controller cards and manuals/software for
them.
I'd love to adopt them out to a good home, and
wouldn't want much for them. I just can't stand to
throw classic computer stuff out, but would love to
lighten the load around here...
They are heavy and shipping would be expensive.
It would probably cost more to ship the units than I'd
want for them...
Contact me off list if you're interested...

Today I found a 3.5 floppy in the SPARCstation 10 with the labeling saying
SPARC BSD is on it, I have been able to read it yet. In the cd-rom drive on
the SPARCserver 20 I found cd titled ORACLE8i The Complete Reference. I can
read the cd with my windows machine.
