Anyone out there who wants a portable TRS-80? I was given an option on
a pristine one, probably literally only used by clean nuns.
No software, but it appears to try to boot. SE Wisconsin, USA.

The latest arrival in the Great Midwestern Micro Hoard comes from deep
within the Balkans, liberated through the heroic act of paying a local
collector to ship it to me:
Here's a short blog entry with links to the obligatory big load o'pics:

I haven't fired it up yet. The seller also sent me a collection disk
images of native software (though much of it looks like translated US
titles) that, as time allows, I hope to write to disk and try out on
the proper hardware.

My MicroVAX 3400 will not power up. I think it is because the right hand
H7868 PSU has failed, the green LED on it does not light up, while on the
left hand H7868 it the green LED does come on. I have no real electronics
expertise, very limited diagnostic equipment (just a multimeter really) and
I know that fiddling with PSUs is one of the more dangerous things you can
do with a computer. That said, I am willing to have a go at repairing it,
but have no idea what might be wrong. All I can say is that it worked a few
weeks ago when I last powered it on, but when I came to power it on tonight
it was just dead, no pops, bangs or smoke, just silence.
Can anyone give me some idea where to begin?
Thanks
Rob

Ack, I'm really jealous over this one :) It'll be interesting to hear
if the presumably dead nvram battery matters -- I think some people are
looking for dumps from working units.

I've been trying to execute the TECO commands in Alice's PDP-10
<http://www.hactrn.net/sra/alice/alices.pdp10> and I keep getting an
error saying "?IFC Illegal character "^" after F". The two command
sequences given have the same form:
[1:i*^Yu14<q1&377.f"nir'q1/400.u1>^[[8
.-z(1702117120m81869946983m8w660873337m8w1466458484m8
)+z,.f^@fx*[0:ft^]0^[w^\
and
[1:i*^Yu16<q1&77.+32iq1f"l#-1/100.#-1&7777777777.'"#/100.'u1r>6c^[[6
.(675041640067.m6w416300715765.m6w004445675045.m6
455445440046.m6w576200535144.m6w370000000000.m6),.fx*[0:ft^]0^[w^\
I'm using tecoc.exe from <http://almy.us/files/tecow32.zip>.
>From my reading of the documentation for TECO, the f command is for
flow control and should be one of:
F' Flow to end of conditional
F< Flow to strt of conditional
F> Flow to end of conditional
F| Flow to else part of conditional
I'm guessing that the commands come from some sort of PDP-10 dialect of
TECO and these commands do something else in that dialect.
: is listed as modifying the next command, so is :i*....* an old way
of modifying the insert command to use *'s as the delimiter for the
text?
Would I be better off pasting these commands into the TECO on
pdpplanet?

Hi
I wonder if anyone knows what happened to Wilber Williams computer
museum in Queensland:
http://www.gizmodo.com.au/2010/07/can-you-help-save-the-uq-museum-of-it/
I ask for a rather selfish reason, I would like a copy of the file:
http://www.computer.museum.uq.edu.au/pdf/DEC-15-H2BB-D PDP-15 Systems Maintenance Manual Volume 1.pdf
Bitsaver has it, but only as a black and white version. I was hoping
that the UQ museum would have at least a gray scale version.
Hopefully there might be a mirror around?
Kind Regards,
Pontus.

There was a POW camp; my wife's grandfather worked there. I can't
confirm the story about the truck ride, but it would be about a 4-5
hour drive (today) from Houston to where the camp was; longer in
1943-5.

Anyone have one working that they want to rent and have returned in

I'm trying to identify and find some early if not first specific production
DRAM chips for a project at the Computer History Museum. I've poked quite a
bit about on the web and found lots of good generic information but not much
about specific pioneering devices after the Mostek 16 KiB circa 1976. In
particular I'm interested in the first and/or early vendors of the following
parts
1) 256 Kib DRAM circa 1983 probably from Japanese vendors
2) 16 Mib DRAM circ 1989 IC Master unknown vendors
3) 1 GiB DRAM circa 2000, probably Micron.
I'm looking for a shipment date, photo, chip size and price information.
However, just a vendor name and part number would be a great starting place.
If any of u have or know of some one who has old IC Master's of the
appropriate era that would be a great place to get vendor, part number and
other information.
Any help would be appreciated.
Tom
