@Sean

I was wondering the same, but perhaps he needs physical hardware for some
specific purposes, like timing and so forth?

The emus (VICE) are quite good these days, though. I can hardly find
anything that VICE x64 won't run.

  If you have a modern system, you could always download a 6502 emulator and
test it on that.  Such a tactic wasn't even unheard of in the day---if I

For a recent telnet in FreeBSD, I had to do a 'mode linemode' before
it would behave like you are describing. Connect, hit return, hit the
escape character (traditional one is ^]). mode linemode . then
I saw local echo and things looked approximately like I'd expect.

Thanks! Mine just arrived a few moments ago.

It powers up just fine, and appears to be a pretty standard PC with a
Phoenix BIOS. It doesn't have a hard drive installed, but I'm planning to
use an IDE to CF board.

It's somewhat loud, so I might see about replacing the fans. I can't
imagine this gets very hot, but we'll see.

6502 code

[dwight]

Hi

 There has been so much PDP and other stuff lately I kind of feel out of place

asking about 6502 stuff.

Anyway, I've mentioned on the 6502.org that QuickSort is not always the fastest

sort. So I wrote a 6502 assembly sort but don't have a machine big enough to 
test it

on. I've only got my KIM-1 just working.

I was hoping someone would like to help me out, possible a Commodore64,

maybe even a PET or Apple II.

It needs about 24 page zero bytes and about 5K of RAM.

It sorts 1K of 16bit integers.

Anyway, if someone would like to help, let me know. I've made several passes

through the code and believe it to be close to bug free but know I'm bound

to have a couple left.

See it as a challenge!

Thanks

Dwight

IBM Server 7587

[Gregory Beat]

IBM has had a number of "industrial computer" models.

The IBM Server 7587 is a hardware platform designed for reliable 24 hour 
operation. It was often used in mid-1990s computer telephony interfaces 
(Pentium socket 7, up to 233 MHz).
Responding to the customer's need for a powerful, reliable ISA bus computer 
that is easy to panel/wall mount and easy to service, IBM developed the IBM 
7587. 

It is a 5 slot ISA/PCI passive backplane, PICMG compliant computer powered by 
an IBM Single Board Computer. The 7587 has a large filtered cooling fan that 
keeps the internal components well under their operating limits, even in hot 
environments. With its shock mounted hard disk drive and adapter hold down 
bracket, the system can withstand the shock and vibration found in many harsh 
work environments. 

Programming interfaces are supported for watchdog timer and thermal monitoring 
functions on the SBC. The system can operate without disk, display or keyboard. 
It is quick to service, with all internal components easily accessible after 
removing the top cover.

TOPS-20 Telnet and Port Forwading issue

[Seth Morabito]

Hi folks,

I don't know if this is the best place to ask this question, but I don't
know of any better forums for PDP-10 discussion, so hopefully it's
on-topic enough.

I recently set up the KLH10 PDP-10 emulator on my network, running
TOPS-20 7.1. It's on a box in my 192.168.1.0/24 network. TCP/IP works
great, I can telnet to it from within my network without any issue.

I also set up my firewall (a box running CentOS 7.1) to port forward
from external TCP port 2320 to internal TCP port 23 on the KLH10 box.

Interestingly, when I telnet from _outside_ the network to my firewall's
port 2320, it works, but Telnet goes into line mode rather than
character mode! I can fix it with telnet escape (^]) by setting
character mode explicitly with "mode character", but that's kind of
annoying to do each time I connect.

It feels like Telnet is no longer doing line mode / character mode
negotiation when I'm port forwarding. It's most mysterious.

If you want to see for yourself, you can telnet to
gatekeeper.retronet.net 2320, which is the KLH10 instance.

Does this ring any bells for anyone?

I'll do that later. I should add a readme with some notes about
exactly what the files are and how to use the images before I upload
them. Otherwise most people will have no idea what they are. You know
what to do with an .HPI image file, other people might not.


On another note, did HP ever provide tools and documentation for
writing Inverse Assemblers for the 1630 series? For the 1650 / 16500
series there is the 10391B Inverse Assembler Development Package which
includes documentation, a compiler, and sample code. As far as I can
tell the IA code space on the 1630 series must be limited to a total
of 8KB as that is the total amount of EEPROM storage for saving an IA
configuration on a 1630G. I wonder what sort of tools they used for
writing IA for the 1630.

Re: looking for keytronics keyboard pad replacement kit

If it's not too much trouble, emergency blankets (aluminized mylar, I

those, then stick them on the mylar and quickly cut them out.

The total volume of everything, including probably at least 30% junk, is

the collection is mostly BA23 and BA123 boxes with PDP-11/73
and one PDP-11/83 along with assorted Qbus boards.  There are

thanks! mine looks very similar. I guess I need to check the backs of

I also need to dig out the chassis to see what model number mine is.
None of the boards have Unibus connectors out the top.

I made some pictures and currently uploading them to

Caution: the images are 3072x2048 pixels JPGs, approx 1,5 Mbyte in size.

The 2 PCBs on the table are the "MP Microcontroller MAW 35-0066-00"
Sandwich disassembled.

W/o documentation I think it is very unlikly that I can get this beast
working again... The cards in the cage are placed in random order
and currently I don't have the PSU, but the former Owner will look for
it. The faceplate says 230V, 3A..

Mostly because they are BIG CRTs

Megatek documentation is extremely difficult to find, which is why I never did
anything with the one that I have.

Re: SGI Indigo Update

Damn, you're right, that's the pinout for the Indy. I have both an Indy and
an Indigo with a modified ATX power supply.


You're running an Indigo on ATX power supply guts? Interesting. My 
co-worker has a SGI Fuel on his desk with a bad PSU and has talked about 
converting it.

I can't for the life of me find the page again that had the pinout (the
service manual is not helpful:
http://www.megarat.com/indigo/docs/indigo_service.PDF).

I'll go and check ;)

I found that in my hunt but I think those pinouts are for the 
Indy/Challenge S machines? The Indy had a soft power on button on the 
front, the Indigo has a reset button and speaker mounted to the power 
supply (but the wires from those are just passed directly to the power 
supply connector.)


Might get a chance to poke at it tonight after work and I'll compare!

Glen,

Could you upload them to http://www.ko4bb.com/
So the measurement community can access them also?
