Available: IBM 3290 split-view Plasma Terminal

by ian.finder＠gmail.com

Hi folks, I impulse bought this thing locally a couple weeks ago, then realized I have no IBM gear to go with it :[ It's a really cool piece of kit, but I've just moved and could really use the space. Just want to get back what I paid for it: $50 + actual S&H. I get a pretty great discount on shipping through work, so even for a big nasty terminal like this, it should be pretty cheap. Unit is in good condition, powers on, comes with keyboard. A couple keycaps are missing, and someone yanked the keyboard jack off the board, but it's been bodged back on and appears to work. Anyone with a soldering iron should be able to do a better job re-connecting the jack, although it appears to work as is. I just don't have time or room for the damn thing. Located in 98105 (seattle) if anyone local wants it-- or I could hold it for a bit if anyone will be in the area soon. Please respond off-list. Cheers, - Ian P.S. Hope for-sale posts are allowed-- been a CCtalk reader for a while and never noticed any issue with them, but who knows. -- Ian Finder ian.finder at gmail.com

Using 10Mb Ethernet with 1Gigabit switches

by chd＠chdickman.com

I've been playing with a couple VaxStations and a qbus PDP11 recently and have been having trouble with connecting 10Mb ethernet to 100Mb and 1Gb switches. I have several 10base-T transceivers that I use since all my 10base2 hardware is in storage. Today for example, I connected a DELQA in the PDP11 to a 10-100-1000 switch and it did not work. I got out a 10-100 hub and put it between the PDP11 and the switch and it worked fine. Another example, my VS4000/60 netboots fine, but NetBSD will not detect the network interface unless it is connected to the "right" switch. All the switches and hubs I am using are from a collection of unmanaged consumer grade stuff (TRENDnet, ASUS, Linksys, etc.) that I have accumulated. Curious if anybody else has similar trouble when mixing old with new and slow with fast. -chuck

VT240 Monitor Error - 9

by robert.jarratt＠ntlworld.com

I just got a VT240 with a VR201 monitor. When I switch it on it displays "??240 Monitor Error - 9" (although the question marks are reversed). The terminal works otherwise. It displays the setup menus, and it works when connected to one of my VAXen. I have looked in the docs I have, but none have troubleshooting information, and I can't find anything online. Any idea what this error means? Incidentally, I used to use a software package called UNIRAS to do graphics on VAXen, does anyone know if it is still possible to find this software? Anyone got anything to exercise the VT240's graphical capabilities? I believe Datatrieve has something, but I don't want to install that just to test the VT240. Regards Rob

Sun 3/50 and Sun 3 keyboards (Re: old Sun metal kbd is GONE!)

Don't have one of those or I'd use it. Did a quick google on the P/N... http://www.upgradebay.com/Products/ProductInfo.aspx?ProductID=169290343 Um... $255?!? They are on the drugs. Yes, I can make one. No I haven't made one. A list member is sending me a real Sun3 kb this week. Of course now that something is moving on this, I wonder if I have a suitable monitor... I know I have a working Viking Moniterm I (and the Amiga card to go with it). Apparently, on this very list, it was mentioned 13 years ago that the monitor has DIP switches for its timing settings (1280x1024 @ 60hz was apparently common, and as used with the A2024-compatible adapter, 1024x800 @ 60Hz or 1024x1024 @ 50Hz) http://marc.info/?l=classiccmp&m=104957388722023&w=2 Anyone know if it'll do 1600x1100 @ 66Hz or 1152x900 @ 67 Hz? Even if it can, would it require an ECL->TTL level converter for the video? A quick google is not revealing tech docs for the Moniterm I (but there's plenty of cautions out there that they fail often). -ethan

IBM PC rear trim panels… Why are they uncommon?

by nf6x＠nf6x.net

It seems to me that a large percentage of original PCs, XTs and ATs that I've ever seen have been missing the plastic rear trim panels. Is there any particular reason why those seem to have been so commonly removed and lost or discarded? -- Mark J. Blair, NF6X <nf6x at nf6x.net> http://www.nf6x.net/

Terminal emulator for TRS-80 Model 1?

by fozztexx＠fozztexx.com

Somewhere in the last couple of days I saw mention of a terminal emulator program for the TRS-80 Model 1, but I don?t remember what it was or where I saw it. I didn?t think about it because I was able to get kermit on the TRS-80, but I just pulled it out again and kermit kinda sucks. It types in all uppercase unless I hold down the shift key, and it?s got no cursor. Anyone know of something that?s better? Follow me on twitter: @FozzTexx Check out my blog: http://insentricity.com

Needed: Diagnostic listings for DEC RL controller&disk drives

by j_hoppe＠t-online.de

Hi all, I'm trying to repair a bunch of DEC RL11 controllers. (These are the UNIBUS boards for RL01/RL02 disc drives). Running the PDP-11 diagnostics ZRLA, ZRLB, ... ZRLN from XXDP or papertape prints out some errors, but without the diagnostic assembler listings I don't understand what's wrong. At the moment I know only of these 4 listings: AC-E040B-MC_CZRLBB0-RL11_RLV11-Controller-part-2_Oct78.pdf AC-E044B-MC_CZRLCB0-RL01-Drive-Test-part-1_Oct78.pdf AC-E048B-MC_CZRLDB0-RL01-Drive-Test-part-2_Oct78.pdf AC-E246B-MC_CZRLEB0-RL01_RLV11_Exerciser_Oct78.pdf These are all for paper tape based MAINDEC diagnostics, and are also incomplete: At least both "part 1" AND "part 2" is needed for ZRLB, ZRLC, ZRLD. Can you point me to some hidden archives? Or do you have more assembler listings for ZRL diagnostics lying around? Bitsavers needs your input! Thanks, joerg
