Anyone here remember RangeLAN2? Anyone have a Proxim RangeLAN2 7520 AP they'd like to sell? None of this is exactly vintage yet, but certainly obsolete... :) Thanks! -Ben

identify this baud rate generator

by hilpert＠cs.ubc.ca

Can anyone identify the equipment this board came from, or the company going from the style of part number? It's a baud rate generator, or presumably is, given the "TTY" on the solder side. ~ 10.7 MHz clock, 12-14 stage divider, late 1970's. http://www3.telus.net/~bhilpert/tmp/brg/ Seemingly odd choice of clock frequency for a baud rate generator, results in some error at the higher standard rates.

This one rides the edge of the first two categories, so if anyone would like the original, FFS, let me know.

S100, but not S100

[cctalk] Old UNIX Systems

by seefriek＠gmail.com

We're doing NetBSD and 80386 again? Evil cabal responsible for crimes against computing again? Jason Thorpe and others were talking about fundamental problems continuing 80386 support, what, almost a decade ago (no...the 80386 is not simply an older 80486)? They announced the intention to drop support in 2007, and dropped it in 2009. It was not a secret and it wasn't a smug "buy bigger/faster/stronger" dictate; they still support VAX and a pack of ridiculously obscure mc68k boxes, after all. 80386 support died because no one stepped up to support it, even though proposals were made as to how to do that. Based on that, the core developers made a decision about how to allocate scarce resources, and in 4 years the world has somehow failed to end. If a single person had stepped forward to take on 80386 as a distinct port, it could still be in there. It not like ns32k or mc88k, where getting things going means recreating GCC support, figuring how to jump to ELF, etc. And yet, since 2009, no one has picked up 80386, which pretty much tells you how really important it is in the grand scheme of things.

SD: Under RT-11

by jhfinedp3k＠compsys.to

Does anyone else who is reading this still use the DEC SD: (Symbolic Debugger) under RT-11? I have been spending some time, of late, becoming more familiar with this software and I have noticed a few areas which could use some improvements. This post is in respect of version Y01.16 which runs under the most recent versions of RT-11, and in particular the SDHX.SYS variant which runs under a Mapped RT-11 Monitor. The two major aspects that could use some improvement are to reduce the Low Memory required from 1124 words to perhaps half that requirement. The second is a lack of a history capability. Doing so will certainly require the use of additional Extended Memory beyond the 8192 bytes already in use and that is probably the major obstacle to overcome. One other aspect that might possibly be changed is the fact that the SDHX.SYS variant freezes RT-11 when the user is at the DBG> prompt. While that is a major problem, I don't know if there is a solution which would allow the user to unfreeze the system and allow other jobs to execute. As for the Symbolic Debugger capabilities that are available under RSX-11, in particular with respect to programs with overlays which the DEC Symbolic Debugger under RSX-11 is reported to posses - even before the overlay is loaded, that may also be possible if there is sufficient need under RT-11. I would appreciate a response from anyone who still uses SD: under RT-11, especially under a Mapped RT-11 Monitor and most definitely from anyone who uses the version Y01.16 which DEC limits to certain versions of RT-11, but which is capable of supporting debugging under versions of RT-11 at least as far back as V05.03 of RT-11.

PDP-11 OS Guides/Texts (RT-11, RSX-11, RSTS)

by pbirkel＠gmail.com

As long as we're talking about teaching & books/course materials, let me pose the following query: Does anyone have any good references for learning/using RT-11, RSX-11, and RSTS (the principal PDP-11-based operating systems), beyond the various online DEC-docs? Absolutely not "for dummies" style books (were "for dummies" books yet been invented in the 70's?), but neither simply a regurgitation of a DEC reference-manual! Thank you, paul

DEC-Writer III LA120 played dead

by hachti＠hachti.de

Just for your amusement - and to help people who might once grep the list archives to find the solution if they're as stupid as me... I just carried a LA120 upstairs into my screenprinting/collection room. And I wanted to test it because it had stayed many months on a pallet under a cloth. After power on it just worked fine. And than the paper ran out. It made a lot of sound with blinking and all that. So far... But when I power-cycled it - it played dead. All LEDs on and all digits lit. I was kinda confused because the digits are processor controlled. So it could not be completely dead. But why didn't it complain and blink and just SAY something?!? Severe firmware corruption? All voltages were there. No fuse blown. Nothing disconnected. The manual helped me: If the cover is open or paper out on power-on, the LA120 will just play dead. Without any further complaints. Many of you out there might know that. But I can imagine that there are some potential future victims of this behaviour: You have been warend now :-) Kind regards Philipp

cctalk Digest, Vol 118, Issue 32

by pechter＠gmail.com

Anyone have archived CD's or ISOs of Debian Slink and Potato and Corel Linux releases and sources... I've got a pet project I want to start work on and I haven't been able to work up. I had Corel Linux running pretty well on an old Pentium Thinkpad with the modified KDE they included. I'd like to look at rebuilding most of it with updated software and security fixes, but I want to compare the Corel sources with the original Debian and slowly upgrade the sources to more secure versions (I had already done new ssh/ssl/glibc about five years ago). I guess I'll stop at the later 2.4.x kernel revs, since they were much better than the 2.2. Bill -- d|i|g|i|t|a|l had it THEN. Don't you wish you could still buy it now! pechter-at-gmail.com

This one is available on Amazon with **LOOK RARE** pricing, currently around $120. I paid a lot less for a copy a while back.

UNIX for Old 486 Boxes

by mcquiggi＠sfu.ca

Hi Ethan: I'd suggest a 3.x version of FreeBSD. I recall from the day that a few megs of RAM will get you support for 10-20 simultaneous users. You can run all the usual servers and services. I used a 3.x box to teach an introductory UNIX class for a couple of years at a Vancouver-area technical college. I can make you an ISO if the FreeBSD site doesn't have 3.x still available. Kevin Message: 17 Date: Sat, 8 Jun 2013 01:38:58 -0400 From: Ethan Dicks <ethan.dicks at gmail.com> To: "General Discussion: On-Topic and Off-Topic Posts" <cctalk at classiccmp.org> Subject: What versions of Linux (or UNIX) are good on old 486 boxes? Message-ID: <CAALmimn9vrAuMHiuXZyyv6TZ6sNKBEot0JLbg1LUE9GbDcmqFQ at mail.gmail.com> Content-Type: text/plain; charset=ISO-8859-1 Hi, All, Going through stuff on the shelf and I've run across a couple of 486-based fully-integrated LCD/touchscreen machines. One is a SCAN Corporation SCANtouch Model 3000, the other is a Planar Systems box. Similarities include limited memory (2x 72-pin SIMM sockets on the SCANtouch or 4x 30-pin SIMM sockets on the Planar, both with "double-sided SIMM" support, so 64MB or 32MB max respectively), one ISA socket (no PCI), onboard NE2000, serial, parallel, 2.5" PATA disk... these systems will run MS-DOS, of course, and Win95 (the touch screen on the SCANtouch is old enough that it apparently doesn't work with Win98 mouse drivers, according to forum posts I dug up). I really don't care about running DOS or Win95 on a touchscreen/LCD machine, and the practical alternative is some flavor of Linux or UNIX. What I'm having difficulty digging up is when the break from low-mem/pre-Pentium systems happened and what distros are on which side of the divide. RedHat 7/8/9 require a Pentium and 64MB minimum >from what I can research/remember. The last time I ran Linux on a 486, it was Yggdrasil (and before that, some early form of Slackware on a 386). So... anyone have a "go-to" Linux distro for sticking on a 486? I know RedHat 5.2 will work - that's what's on my PS/2-E (w/486SLC and 12MB of free mem I was recently discussing). Any other choices? At one time, when a Dell P-133 Latitude laptop was my main machine, I ran Solaris 7 on it (because it was a better choice than Linux at the time) even though it still had some issues (and workarounds) with the NeoMagic video chipset and the 3Com 3C589 PCMCIA NIC. I suspect this is likely to have similar "challenges". I've dug up full specs on the Scantouch 3000 innards - PCM-4890 integrated CPU board, NE2000 (Realtek RTL8019) Ethernet, C&T 65545 video chipset w/800x600 max LCD resolution, Sharp LM10V33 VGA (640x480) 10.4" color LCD, VIA VT82C496G chipset, , PC104 sockets... so I have little concern about getting *something* working with it. Getting 10-year-old RedHat working on a Pentium-class machine isn't a real challenge, but it's been long enough since I've really fiddled with 486s that specific memories of system configuration are getting a bit fuzzy. At one time, over 15 years ago, it was a daily thing knowing the ins and outs of what the 486 could and couldn't do, before CPUs and memory and clock speeds took off like a rocket, and when 4MB was ordinary, but more than 16MB was uncomfortably expensive for hobby gear. Helpful suggestions wanted. Thanks, -ethan

Old UNIX Systems

by healyzh＠aracnet.com

I've been working on getting shelving installed in our Garage, and as a result, I've been digging back to some systems that have been buried. Right now I'm moving a bunch of Sun hardware and it hit me. What good are old UNIX systems? I'm curious, what are people using things like Sparc 2's through 20's for? Or even Ultra 60's and older? Part of the problem I'm looking at is that you can get something like a Raspberry Pi that will cost a fraction of what a Sun system costs to run. I won't ask this about my two SGI O2's, as they're artwork. BTW, I'll be honest, I'm actually using two Sparc 20's right now. Each one sits on top of two Record Crates, and acts as a speaker stand. They've filled that role for several years. Somehow though, furniture and artworks really aren't the uses I'm looking for. :-) Zane -- | Zane H.

discontinuance of VMS

by mcguire＠neurotica.com

I am still looking for a "horse's mouth" reference, but it seems HP has just given the VMS community the finger. "Ric Lewis at HP sent out a letter basically saying VMS is dead. Support up through 2020, but 2016 is the last sale of VMS- supported hardware." Now, of course, "will only be sold for 2.5 more years and will only be supported for 6.5" doesn't exactly say "dead" to me; it says "WILL EVENTUALLY BE dead", but still, this does kinda suck. But it's awesome that it lasted this long. From 1978 until 2020 is a great run in this industry, one for the history books. And I'll be running it, God willing, well after that. (if I'm still breathing!) (Now we get to watch all the stupid suits who equate "no longer sold" with "doesn't work anymore". Heh.) -Dave -- Dave McGuire, AK4HZ New Kensington, PA
