Why the National Archives needs punch-card readers (Fwd by SMECC)

by COURYHOUSE＠aol.com

Scruffy Millennials covet old record players because they dig the format; the National Archives and Records Administration keeps old file players around because legacy digital data demand them. "I am preserving every file format that has ever existed on the web, or that any of you have ever used in your work on a daily basis," said Leslie Johnston, NARA's director of digital preservation, who spoke at a March 10 FedScoop event. "In one transfer from one agency, we received not only their email, their Word documents, their PDFs, their PowerPoints -- we actually received the entire contents of their hard drives." http://bit.ly/1QVLam4 enjoy - Ed Sharpe archivist for SMECC

Which RT-11 for an 11/03

by rich.cini＠verizon.net

Is there a listing somewhere of what versions of RT-11 work with which CPUs? The Heath H11 uses the LSI-11 which I think is an 11/03 equivalent. Is there a specific version (or maximum version) designed for this CPU? I tried v4 using a method I found on-line (modifying with SIMH to make it bootable as a TU58 image rather than an RK) but it doesn't work so I wanted to first eliminate the system version as the potential problem. Thanks! Rich Sent from my iPhone

Introduction and Alpha Micro AM-1200 query

by rsponholtz＠hotmail.com

Hi Everyone, I just subscribed on the cctalk mailing list, I thought I?d introduce myself.? The first computer that I ever used was an Alpha Micro AM-100 at my high school, where I had the extra project of figuring out Pascal and explaining it to the teacher.? I?m pretty excited about Eric and Al?s decapping project ? I?m imagining a FPGA-based AM-100 emulator in the future! In fact, I recently picked up an Alpha Micro AM-1200 that I?d like to get running.?It?s giving a selftest error indicating a memory problem that hopefully I can figure out how to track down. After that, I?ll need to get an OS on an appropriate disk (I don?t think the disk is working). Does anyone here have any info or documentation on these machines, or maybe even some software? The info out on the ?net on these things seems pretty minimal. Back to the intro: I went to University of Colorado Boulder for Computer Science back in the mid-80s, graduating in 88 after doing a lot of work under VMS and various Unix machines.? I now work for Microsoft (in cloud pre-sales tech), and have a small collection of old computers ? AM-1200, Microvax, Mac SE and HP 9000/300.? I recently picked up a nice ADM-3a that I got working by replacing some RAM chips. ? Anyway, thanks for your help, and love the conversation! Ross Sponholtz rsponholtz at hotmail.com

Which RT-11 for an 11/03

by Gary＠realtimecomp.com

There is no difference in the LSI-11 board on an H-11 and a pdp-11/03. What DEC did do was cripple Heath's version of RT-11 (called HT-11). It would only work with Heath's H-27 floppy drive unit. The Heath serial, parallel, and memory cards were all compatible with DEC's offerings, AFAIK. That being said, I personally don't have experience with true RT-11 on the H-11. -------- Original message -------- From: Richard Cini Date:03/10/2016 4:09 PM (GMT-05:00) To: "General Discussion: On-Topic and Off-Topic Posts" Subject: Re: Which RT-11 for an 11/03 If I have time tonight I'll log the session with "verbose" set on the TU58EM. Again, I'm trying the trick of booting from a TU58 emulator and an RK image with DD as the boot target (supposedly can work but maybe slow). I can see the blocks being read in but it stops and doesn't give me the sign-on banner. Rich Sent from my iPhone

Honneywell multics? from panels. the inline phots in this message folks...

by COURYHOUSE＠aol.com

and for horrible deep level maint. I would imagine they would be useful.... they look like something too complex to let operations level people diddle with... but are these used with exactly WHICH Honeywell system? If we are going to display them need to tell the right story in the museum. Ed# In a message dated 3/12/2016 7:44:50 A.M.

Assuming the work the same on a Multics box as on a regular L66/DPS box the only time they were really used was if you split a 2 x CPU system into 2 x 1 CPU system, or changed the memory configuration from interleaved to non-interleaved.

Honneywell multics? from panels. the inline phots in this message folks -smecc

by jnc＠mercury.lcs.mit.edu

> From: Charles Anthony > The enormous number of configuration switches is due to the extreme > modularity of the system. ... Each bank could taken out of service The really amazing thing (considering the vintage) was that that reconfiguration could be done with the power on, and the system running! E.g. MIT had a two-CPU three-memory system; at night, they used (while the system was running!) to take off one of the CPUs and a memory box, bring them up as a separate development system, and in the morning, add the 'borrowed' CPU and memory back onto the main system - without ever shutting the main system down! People using it at the time could't even tell it had undergone a mitosis, and then a merge. Noel

Any word on the Multics revival front?

by madcrow.maxwell＠gmail.com

When Multics was officially released as free software a couple of years ago, there was a flurry of activity aimed at getting some sort of emulator up and running to run it. Did anything ever come of that or did folks just lose interest (or find out that the needed GE/Honeywell hardware was too poorly-documented to write an emulator of) Mike
