ROLM 1601 (RuggedNova) 1970 Brochure

by billdegnan＠gmail.com

I may have more 1601 stuff, if I find I will scan and post. I know there is the upcoming Nova event so I thought this would be good timing. I have a lot of Nova docstoo, but I believe they're already posted on the WWW.

Hi Bill, many thanks for the efforts spent on scanning those fantastic brochures. I have some of the 1602s and a MSE14, but has any one out there seen a 1601 in real life? Was this really sold or was it still a paper-machine as it was replaced by the 1602? Any comment from contemporary witnesses is highly appreciated ;-) Thanks again to Bill, Erik. e--- Bill Degnan via cctalk <cctalk at classiccmp.org> wrote: > For those interested in Rolm / Data General Nova Minicomputers I have > scanned the hard-to-find Rolm Corp Rugged Nova 1601 brochure from 1970.

i860: Re: modern stuff

by wdonzelli＠gmail.com

AIX was ported in very cut down manner and used on the f960 and h960 routing cards used on the early T3 based NSFnet. F960 was FDDI and H960 was HSSI. Come think of it, I think the v.25 and ether net cards also used i960, just a smaller version. -- Will On Oct 29, 2018 12:13 PM, "alan--- via cctalk" <cctalk at classiccmp.org> wrote: I know i960 is a very different beast, but was there ever any high level OSs that ran on it?

Modcomp VME bus 68000 computer

by lyokoboy0＠gmail.com

Hello, been a while since ive written to the list. I met someone the other day that used to work for modcomp. He gave me a tour, he still has working modcomp computers in his home. He was clearing out a bunch of stuff, he gave me a bunch of terminals and dos era computers. Among the computers is a modcomp branded motorolla 68k based machine. I can not find any information on the system. From what i understand, the system was to be tied in to the modcomp minicomputer bus and used as a modern alternative for large antiquated disks and tapes. There is a large pair of interface connectors on the back, never seen anything like them before. I do not have a modomp computer yet, but this 68k machine looks quite interesting. It is essentially a vme bus backpane in a desktop computer case. A hard disk and tape drive are installed. Looks to have floating point and network card as well. I managed to make the proper serial cable, and was able to get to a debugger and monitor at power on. I was under the understanding that this machine could run a port of unix to 68k, called unix/68. I am uncertain of any details on the machine, i was hoping someone here could me in the right direction of getting the machine to boot. The drive still spins up, it may even have an install of unix on it, i might have to type in some kind of boot parameter or jump to some address from the monitor to kick off the boot process. Any advice on how to proceed is appreciated. Within the following month i am supposed to get a mountain of modcomp documentation, ill have to check back here and see if its duplicate or original information and scan it all. He was also going to give me a copy of a modcomp emulator he wrote, I have found no such thing elsewhere on line, so perhaps it would be of use to someone else here too once i get it. --Devin D.

A very sad PDP-8/S

Damn, that 'left all the synths in the basement, and it got flooded' story is painful. In my opinion the ONLY way to preserve tech relics, is for individual(s) who understand the gear, to take personal responsibility for it. Companies, beancounters, economics... all are deadly enemies of historic artefacts and documents. Small world. All the way through that I was waiting for a mention of Fairlight Instruments (Synthesizer company in Sydney.) But none. Oh well. I worked at Fairlight from the mid 80s for several years (till they shut down.) There's even a clip online from Fairlight, with me in it: https://www.youtube.com/watch?v=21S1Okh2nlc Fairlight Instruments Factory Tour 1986 part 2 Starting at 2:18, the young fellow with the dumb haircut and too shy to say anything to the camera, is me. Ha ha... and I can date that event as very shortly after I got married, since for the wedding was the only time in my entire life I ever shaved my beard off. I hate how I look without it. Since I married in June 1987, I think the year listed on the video is wrong. Oh, and then the camera pans to a proto-board circuit I was working on. It's a bit of a tangle. I think that was part of a video timebase corrector system I was working on. My proto board, I still have it. >If there are any special 8/S lightbulb housings that were plastic, I'm happy to CAD them up and 3D print for your (er, museum's) machine at no cost, if I had some measurements or good photos. >I'm only 'up the road' in Brisbane. Thanks for the offer, but it won't be necessary. I'm spending today cleaning the machine and working out exactly how to make the 'clear protective base.' Bought most of the materials today. The front panel is in pieces atm. And clean now. Incidentally, several people called the material used for the lamps shroud plate 'MDF.' It's not, it's that high density cloth+bakelite (or something) material used for electrical switchboard panels. Very tough stuff. I'll try to get a blog page started for this machine tonight, or at least by tomorrow. If you're ever down in Sydney and have spare time, you're welcome to visit. Address via email. Guy

Updates at retroarchive.org...

by geneb＠deltasoft.com

First up is the addition of Crescent Software's entire product line. The company produced a number of good library suites in the late 80s and early 90's. Note these are all DOS products - the Windows product line was sold in the early 90's. http://annex.retroarchive.org/crescent/index.html When the documentation arrives, I'll be paying the IA to get it all scanned. It's a lot cheaper than me buying a Scribe scanner or building a DIY version. :) Next up is a HUGE CD-ROM and FTP site archive I've been working on. http://www.retroarchive.org/cdrom/index.html What I've done here is pull CD-ROMs from the Internet Archive and make them easily browseable. I've also extracted the contents of each of the zip, etc. files and created index files for those as well. The goal was to make the material more easily accessible for both us meat bags and search spider bots. This is going to be a long term project that will end when I've either exhausted the available CD-ROMs on the IA, or I die, whichever comes first. ;) There's a number of holes in the sets that are on the IA - if you've got a disc that would fill a hole, please consider making an ISO of the disc and upload that along with a photo of the disc to the IA and then let me know so I can get it processed. I'm also looking to acquire a manual set for QuickBASIC 4.5 and the Microsoft Professional Development System 7.1. If you have either one, please contact me!

And easy to add to the simple base frame I had in mind. Zero changes to the machine. I was too stuck in modern fast digital thinking - 'RF-tight metal case' etc. Ha ha, on reflection I don't think so. Guy

Very happy to have this one. Re dirt - actually it's pretty grimy. I did a preliminary dust off for the pics, but later it will get a complete cleaning. After I have docs on where all the flip chips should be, and I figure out a non-marking way to record which ones were in which slots, as I remove them to clean each one and the backplane. With precious museum pieces like this, you DON'T write numbers on them in marker pen. Just doing a quick eval now, since I'm already ridiculously stack-pushed with multiple other projects. Highest priority: Make a mechanical guard for the wired backplane pins. As it is now, just putting the machine down on a desk wrong could do major damage. Have to do this before I even pack it away in the box again. It's just been *really* lucky so far, with only minor pin bending despite inadequate packing. Guy
