FTAG: AlphaServer DS15, Sun T5140, Sun Blade 10, HP Proliant DL380 G7, VT220 [London, UK]

by Andrew Luke Nesbit

Hello all again, With a heavy heart I need to find a new home for the following beautiful hardware: - AlphaServer DS15 server - Sun SPARC Enterprise T5140 1U rack server - Sun Blade 10 mini tower - HP Proliant DL380 G7 2U rack server - DEC VT220 with screen, keyboard, and various adapter cables Please note that the Sun T5140 and HP DL380 are deep (700mm for purposes of installation in a rack). I'm starting a new job next week and intend to focus on that and my family. I've stopped working on various projects and I am vacating my studio workshop, so I have a lot of things to give away or sell. The above items are all FREE FOR COLLECTION ONLY (a car will be fine to transport the above items). I am located in London, UK. Post code is N15 4QL (Seven Sisters and Tottenham Hale) in Haringey, London. Kind regards, Andrew

First C compiler outside Bell Labs?

by Lars Brinkhoff

Hello, Which was the first C compiler written outside Bell Labs? I have a candidate in mind. Alan Snyder interned at Bell Labs in 1973. Later at MIT, we wrote a C compiler for the PDP-10. This would have been 1974-1975.

Kind regards, Andrew Well, Rob Pike designed one: http://doc.cat-v.org/bell_labs/blit/ I guess the original hacker scene for the 68K was around Hal Hardenberg’s newsletter: https://en.wikipedia.org/wiki/DTACK_Grounded The ready-made 68K SBC’s only arrived 1984-1985: https://en.wikipedia.org/wiki/Sinclair_QL (I think Linus Torvalds owned one) https://en.wikipedia.org/wiki/Atari_ST https://en.wikipedia.org/wiki/Macintosh_128K https://en.wikipedia.org/wiki/Amiga_1000 All these machines are rather similar at the hardware level - 68K processor, RAM shared between CPU and display. Only the Amiga had a (simple) hardware GPU. What set the SUN-1 apart was its MMU, which none of the above have. What influenced the timing was probably that Motorola made the 68K more affordable by the mid-80’s. Paul

Can I use Apout simulator on Windows 10?

by Saif Resun

hello there! I want to use Unix Operating system but I use Windows and from TUHS I got to know that Apout can be installed on FreeBSD 2.x and 3.x, and on RedHat Linux 2.2. Can I use it on Windows 10? Thank you.

Looking for a paper..

by Warner Losh

... or the proceedings that it's in. The paper is by Chris Torek entitled "A New Framework for Device Support in Berkeley Unix" from Proceedings of the UKUUG, London, Summer 1990. The Google hits I'm getting in the proceedings suggest I'd like a copy of the full thing. Closest I've found is from 2005 or 2006 on archive.org... Nothing in the TUHS archives I was able to find.... This paper is referenced in Chris Torek's "Device Configuration in 4.4BSD" which only ever seemed to circulate in draft form. That I have a pdf of which I converted from a ps that was on NetBSD.org... Any chance I can get a copy of it? Or will I need to figure out inter-library loan again for the first time in almost 2 decades... Warner

Anyone know ancient versions of XLC?

by Ben Huntsman

I know this is a strange place to ask, but it was suggested to me that some people who may know may follow this list... Anyone on here used IBM's XLC in very old versions? Anyone know what the argument -qdebug=austlib does? I can't seem to find any documentation that says... It would have been an argument for the compiler shipping with AIX 3.2.5, I believe. Thanks in advance!

Re: [TUHS] (no printed copy) (was (no subject))

Nemo Nusquam: In this informal survey, I side with Dave, though I prefer to read in my comfy well-lit chair with tea/coffee/cocoa.B (A very similar thread was aired on MO last year.) ===== I should point out that, having at various times spilled hot chocolate on a tablet and on a paper book, it is much simpler to recover when it's a tablet.

CP/M predates the Altair / S-100 bus, and was designed for a heavily hacked Intellec-8 system. CP/M was developed on a PDP-10 based 8080 simulator in 1974. It was developed for the dual purposes of creating a “native” PL/M compiler and to create the “astrology machine”. The first versions of CP/M were written (mostly) in PL/M. To some extent, in 1974 both Unix and CP/M were research systems, with a kernel coded in a portable language — but aimed at very different levels of hardware capability. In 1975 customers started to show up and paid serious money for CP/M (Omron, IMSAI) - from that point on the course for Kildall / DRI was set. The story is here: https://computerhistory.org/blog/in-his-own-words-gary-kildall/?key=in-his-… <https://computerhistory.org/blog/in-his-own-words-gary-kildall/?key=in-his-…>

PC Unix (had been How to Kill a Technical Conference

by M Douglas McIlroy

Is anyone > on this list familiar with Bell Labs management thoughts > on selling IBM on LSX rather than "dos"? IBM famously failed to buy the well-established CP/M in 1980. (CP/M had been introduced in 1974, before the advent of the LSI-11 on which LSX ran.) By then IBM had settled on Basic and Intel. I do not believe they ever considered Unix and DEC, nor that AT&T considered selling to IBM. (AT&T had--fortunately--long since been rebuffed in an attempt to sell to DEC.) Doug
