Ya.  But there's still something to be said about older IBM servers.  ;-)

Its degraded. There are no spares in the config. It did once rebuild the 
non-operational drive, but dropped it again very quickly. 
IBM recommended running the box from a UPS and never powering it off. I can't 
really afford the electricity

OI think there are plenty of P390 boxes around, and most of the software is 
available, but its interesting to a Mainframe OS on real hardware. 
The Hercules emulator on a modern (Core i3 or Core I5) PC is much faster than 
the P390.

Reviving a 3 year old thread...

For anyone that does any work with old HP logic analyzer inverse
assembler files, it turns out that it is possible to decode the 68000
based logic analyzer IAL style IA binary files back into equivalent
source code that can be assembled again with the 10391B ASM.EXE
assembler. (No idea yet about the 6809 based 1630 series logic
analyzers. Those use a different binary format).

Decoded Inverse Assembler .S source code files for the 10342B HPIB,
RS-232, RS-449 interface posted here:

Either way, COOL!!!

It sounds like you're doing some good computer archaeology / preservation.

Folks,

 

Well in case any one has the slightest bit of interest, I have now plugged
the RAID card back in and after replacing on of the drive carriers I can get
five of the six drives to spin up. Its now copying stuff to my Buffalo NAS
but as its 10Mbit LAN its not terribly fast. I think the NAS isn't very fast
either. It looks like zipping up the files and FTPing the ZIP files might be
the quickest way to go.

I thought I had captioned that picture. It's the original RAID controller
which I am not using. If I plug it in it starts the disks in the RAID array
which takes ages, and steals the hard disk BIOS vector which I need for the
SCSI card that's running the system.

I didn't want to remove it fully as I need to label the cables feeding it.
One feeds the top drive bays, and the other the bottom so if I ever need to
put it back it I need to know which is which. 

If I get some free time I will have a go at starting the disks in it and
repairing the RAID array, and perhaps copy the disks that are installed.

I gotta ask, what's the deal with the dangling card?  That cracked me up!

 

Thanks for posting some pics!

Well I found an XGA2 card in the pile of bits so now I have 1024x768 display
resolution. I have swapped the CDROM for a SCSI DVD drive. 

I managed to boot MTS and there are a few pics here:-

It isn't. I've asked Ivan and he hasn't been willing to release it, mainly 
because he doesn't think anyone will be able
to do anything with the code because the TX-2 instruction set was in a constant 
state of flux.

There were a few things CHM got from Ivan within the past few years. I'll see 
if someone else had better luck.

SOT: OCR errors PDF

[Kevin Parker via cctalk]

Hi guys - wonder if any OCR aficionado can help me out please.

I'm trying to clean up some old computer docs.

One of things I'm doing is running OCR over them, in particular Adobe's 
ClearScan which I really like for document clarity and small
file sizes.

A few of them are producing the error:

Acrobat could not perform recognition (ocr) on this page because:
ENU

Most OCR errors relate to renderable text but I can't find an explanation for 
"ENU"

Has anyone encountered this OCR error and can tell me what it means please. 

Thank you.

RE: Original CAD code in the wild?

[Steve Malikoff via cctalk]

I don't know if any source is still available, but for a long time I've been 
fascinated by Ivan Sutherland's Sketchpad running on the TX-2:
https://www.youtube.com/watch?v=USyoT_Ha_bA

Since Sutherland's technical report is also on the web 
(https://www.cl.cam.ac.uk/techreports/UCAM-CL-TR-574.html) I reckon it would 
make for
a great 3rd-year Computer Science graphics assignment, to replicate Sketchpad 
using a high level language. A look through the report shows the
use of rings, linked lists, recursion, storage considerations, maths, graphics 
and so on (only needing to replace the light pen with the mouse
of course) which could be a fascinating exercise for a student.
Yes there are already Sketchpad-named apps and Sketchpad-like programs, but I'm 
not sure if there is a near-100% faithful recreation of that
original program as demoed in the film out there.

Steve.
