PI doesn't work yet, and the only devices which sortof work are the CTY, CLK, PTR and PTP. I've got some -10 code which it executes built into the program so I can test instruction speed... about 500k eips (emulated instructions per second) on a 6x86... I'm basing mine on Bob Supnik's simulation control package, which is really nice in itself.

Computerworld Article

by lemay＠cs.umn.edu

Computerworld's front page article is on computer junk, ie, the problems companies are having with disposing of 'old' computers. Just thought i would mention it in case someone wanted to read the on-line version: http://www.computerworld.com/home/print.nsf/all/000410D386 -Lawrence LeMay

Research Machines Link 480Z

by flo＠rdel.co.uk

I've just obtained an RML 480Z. This machine was commonly in use in schools in the UK during the 80s, as an alternative to BBCs or Spectrums under a government initiative to keep our computer industry alive. Unfortunately, there are no cables or documentation with it. It has a large array of DIN sockets at the back for cassette, two monitor connections, and two serial ports. Does anyone have the pinouts for these sockets? I'll email Research Machines as well to see if I can obtain any documentation, but the only reference to 480Z on their web site is on the Y2K page, where it says that they don't have a real-time clock.

New stuff and lots of Digital help

>> 4. I'm need a mouse and monitor cable for a VaxStation 3100. > >Well, I run mine with a VT420 for a head. Shoot, most of my Alpha's don't >even have Monitors attached to them, and NONE of the VAXen do. > > Zane Zane, thanks for the info and suggestions. You talked me into leaving the uVax2 alone with its Ultrix... And I'm not sure about the HSC-70, but it came in as part of the 11/44 when it was scrapped. So, does anyone have any extra Dec Modified Modular Jacks (MMJ's) for the console port or the odd SCSI cables for the VaxStation 3100 or know where they can be found?

Nov 1976 Interface Age magazine

by paulrsm＠ameritech.net

Does anyone have the November 1976 issue of Interface Age magazine? There is an article by Steve Wozniak publishing 6502 floating point routines. I have the August 1976 Dr. Dobb's Journal with the same or similar information. I want a copy of the Interface Age article so I can compare the two.

It does if you have the bonus pak. I also have the NT4 clients kit for OS/2 V3. I'd still like to bump it up to 2MB if possible. Allison
