Fw: *URGENT* moving IBM 5360 to museum-need advice

by netcafe＠pirie.mtx.net.au

Hi folks, This gentlemen could use some expert advice. I don't know diddly about IBM stuff of this magnitude, so, at his request, I have reposted his plea here. Can someone respond directly to him with some useful information? Thanks in advance..... I've also suggested that he join the CC list...:^) -----Original Message----- From: Tony Epton <aceware(a)iinet.net.au> Newsgroups: alt.folklore.computers Date: Saturday, 19 December 1998 18:04 Subject: *URGENT* moving IBM 5360 to museum-need advice >On Tuesday we will be moving an IBM 5360 10 Km from a warehouse to our >museum. > >Can anyone please give me any advice on issues such as how to lock >down drives and any other steps which should be taken to protect the >machine while moving it. > >I already have another IBM 5360, with a disk expansion bay.

Well Don't feel too bad everyone, at least we were represented. I was kind of passing by Boston this evening (on my way >from Connecticut to New Hampshire). So I made plan for a little detour when I saw this original message. I was not familiar with the "alley" in question so it proved to be a pretty painful adventure (for any of you familiar with the streets of downtown Boston). I knew I wouldn't arrive by 6pm, but when I finally found the right dumpster, it was closer to 8pm. All that was left were two empty steel racks. While I was rummaging an employee happened by on a cigarette break. I asked if this was the "right" dumpster. He said that it was but that there was a line of MIT students waiting when the computers hit the loading platform. They apparently didn't last long. Now, aren't you glad you didn't all drive into Boston like I did? Merry Christmas, Jon ========================================== >< That is today! If you're in Boston and want a PDP-8 or want to help >< someone get one, please act fast! Please pass this note on to anyone >< you feel could help rescue this system. > >Damm, no wau I could make it in there and I want one too. > >Allison > >

Couple oddball RSX-11M questions

by healyzh＠aracnet.com

Since DECnet I can get files from my Linux box to the VAX, and from there to the PDP-11 when it's running RSX-11M 4.2 it's now easier to get stuff transfered to the PDP-11, and this weekend I hope to have TCP/IP working under RT-11 since I figured out how to transfer files from the RSX disks to the RT-11 disk. Now the first quesiton is this. I've got a bunch of RL01's and RL02's with software on them, and when I got them I backed them up onto my Linux box so I could play with them in the Emulator without having RL01/02 drives in the house. Using the network I should be able to transfer those Disk Images over to the PDP-11. However, can I mount those disk images under RSX-11M 4.2 like I can RT-11 disk images under RT-11? If so what do I need to do this? Second question. As I understand it, using DECnet it is possible to use the tape drive on VAX from another VAX. Well, the VAX in the house doesn't have a tapedrive, and I've not run the network out to the garage. So is it possible to have the VAX access the TK-50 on the PDP-11/73 via DECnet? Zane | Zane H.

Another find available in Maryland

by mtapley＠swri.edu

All, Next time I come to Maryland I am $^&(*& well going to bring more luggage. Awright, gentlemen, start your engines. The finish line is the Village Thrift Store in Laurel, MD, on the north side of 198 about a mile west of 95. (Same place as last time I found a cool computer while travelling and couldn't carry it home.) The prize is a Hewlett Packard Portable Plus together with an HP 9114B box (which I think is just an external battery powered 3.5" floppy. Anyone?). It runs Lotus 1-2-3 and there are a couple of other programs on it which I didn't have time to explore. There was only one power supply for the computer plus the external box. Price was not marked. The store worker quoted me $30 for the two of them, but (already aware that I could not pack it) I said "hmph" and walked off. Hopefully he'll now quote you a lower price. There were HP-IL (?) cables connecting the two. The computer said it had a 300/1200 boud modem, and did have an RJ-11 jack. It also said "file not found" on drive A: and had about 2.7 Mbytes left on drive B: That's about all I remember about it. Let me know how it is... - Mark

TI 9900N

-----Original Message----- From: Max Eskin <kurtkilg(a)geocities.com> To: Discussion re-collecting of classic computers <classiccmp(a)u.washington.edu> Date: Saturday, 19 December 1998 8:47 Subject: TI 9900N >I just got this curious item from somebody. It's labelled LORAN C >NAVIGATOR on the back. I haven't powered it up yet, but I guess this is >something similar to GPS Well, sorta. ie both are navigation systems. LORAN is a civil version of a radio hyperbolic navigation aid developed by the Brits in WW2. The Germans had a similar thing, which was originally based in the Bay of Biscay, when the Brits found out about it, instead of destroying it, they had charts made to suit it, and it was used extensively by Coastal Command in the area. It was continued as a nav service after the war, last I heard, it was actually still operating, but that was about 7 or 8 years ago now. The British version was called GEE and was used to navigate (mostly) bomber command aircraft, although I believe Coastal Command and possibly the RN minesweepers and other small ship also used it. In those days it was mostly used by aircraft though. >(only LORAN is on the ground, isn't it?). LOng Rnge Area Navigation. No, it doesn't really matter, it will work in a ship, a plane or a car. (Or on foot if you have a small enough one to carry.) >It looks pretty old, and certainly has digital electronics in it. Could >someone tell me what to do with this thing? Would it be useful in a car or >an airplane? (I have neither) A small boat, like a yacht or a power boat could use it. If they do, and you have the the special maps it needs, then yes, you should be able to use it ok. I know it was popular with small boats in the US area til a few years ago, yachts especially used it quite a bit. I found the following web site, info there says LORAN-C is still operating, and it now seems likely it will continue til 2005 at least. http://www.illgen.com/ila/news/LoranDecision.htm Hope this helps.

IT's basically a specialized 100khz reciever and signal processing system coupled to a microporcessor to translate LOP to lat/long. Accuracy better than 1mile and typicaly .2mile. I have a smaller one in my plane and still use it. I wouldn't mind having one of the old TIs as they were amoung the first commercial loran C. Allison
