DG stuff arrived, plus a load of ibm diskettes & manuals

by jwest＠classiccmp.org

Stuff I got today, some of it will be available for trade. Data General blue rack Eclipse S/120 cpu 3rd party paper tape reader DG qfloppy 8" floppy drive DG 6100 disk drive DG 5821NT blue terminal 4 keyboards for 5821 terminal DG terminal printer 1 Pictures are at www.ezwind.net/jwest/dgporn Unfortunately the 5821 terminal is suffering from extreme screenrot. Most of the stuff is fairly dirty on the outside but quite clean on the inside. I also got the following DG manuals in case anyone is in need of copies: System manual (log of config/mods, local wiring diagrams, some schematics, PM's & upgrades, etc.) Eclipse S/120 Diagnostic & Maintenance manual Eclipse S/120 Computer System Hardware Reference Eclipse S/120 Assembly Language Programmer's Reference Programmers Reference Series, mod 6097/6098/6099/6100/6103 DG disc subsystems Dasher TP1 Terminal/Printer User Manual Dasher TP1 Terminal/Printer Operator's Manual Technical Manual (6040-6043) Dasher TP1 Technical Manual (6040-6043) Dasher TP1 Field Service Maintenance Procedures In addition, for some odd reason I got about 100 IBM sys/32/36 8" floppies in two IBM logo cases. Some of them are still in the shrinkwrap. Then about 9 or 10 of the normal size 8" floppy disk boxes, each full of IBM disks. Some are IBM microcode, some are IBM programs & utilities, most are userdata. Also got the following IBM manuals: IBM system/32 operator training book (includes sys/32 introduction, student data disk, and two cassette tapes) IBM system/36 system reference Sys/36 system messages, vol1 Sys/36 system messages, vol2 Sys/36 RPG messages Sys/36 Utilities messages, vol1 Sys/36 Utilities messages, vol2 All the ibm diskettes and ibm manuals are available immediately. I will keep most of the diskette cases. The DG stuff I'll keep till I do my DG refurb, then some of it will become available, likely the S/120 cpu. Jay West

Media Transfer (was RE: Semi-OT: IDE & SATA to USB "dongles")

by aek＠bitsavers.org

> it would be nice to offer the option to copy to a > disk image as well > they can access the files under an emulator. > I'm guessing that's the only way to access some of the data. You should just image the disc, assuming you only have one shot at reading the data, and mess with interpreting it as a second step. Running an emulator with the necessary app, and screen scraping may be necessary to recover content in some cases. -- I should also mention that part of my charter is to build a library of media and file formats (I need it to interpret the stuff in the CHM archives) and to start putting together emulator suites for data recovery and for use in Museum online and physical exhibits.

Exxon series 500?

by rigdonj＠cfl.rr.com

Anybody know what this is? I found three boxs of new 5 1/4" disks for one today. I picked them up becuase they're 96TPI DS DD (aka DS QD) and I can use them in my SB-180 puters and Nicolet DSO. I'm just wondeering about the computer that they're supposed to go with. Joe

Sun Storage Array, yet again

by dgy＠DakotaCom.Net

I have two of these: http://sunsolve.sun.com/handbook_pub/Systems/SSA_219_7Slot/SSA_219_7Slot.ht… Each has a pair of PSU's in it. I assume for redundancy. However, the PSU's in one unit are strappable 110/220VAC while those in the other unit are 220VAC. <frown> If the PSU's are just redundant and aren't actively load sharing, then I *should* be able to swap one 110/220VAC for a 220VAC and run each array off a single supply (taking care to hack the sense signal for the second supply so the array doesn't continually report a supply failure). Am I missing anything here? Granted, the two supplies possibly *do* share the load as a side-effect in normal operation. But, I assume the intent was for a single PSU to be capable of powering the entire device in the event of a failure in the "other" PSU? Thanks! --don

using the Kennedy tape drive under RT11

by henk.gooijen＠oce.com

Hi all, I have connected the Kennedy 9100 open-reel tape drive to my 11/84. The interface board is the TC131. It sits in a UNIBUS slot, and the 3 cables are wired to the tape drive. The NPR switch is set for that slot. I can mount a tape and after pressing "LOAD", the tape is moved to load point, after which I can by pushing a button set the drive on-line. So far, so good. When I boot RT11, I see (with .show dev) that MT at 172520 is installed however, MS at 172522 is installed too! Using RSX11 (show aco) it lists: MTA - CSR 172522. That seems like a conflict to me: MTA (172522) and MT (172520), where at 172522 would be MS ...? As this is my first actual use of tapes, this is my first puzzle. Next: suppose I mount any tape (contents unknown and irrelevant), which commands could I execute? I tried the following (excuse my stupidities) under RT-11: .dir ms1: --> returns: ?MON-F-Dir I/O err - 011020 .init ms1: --> returns: ?MON-F-Dir I/O err - 014740 is this meaningfull to somebody? Should these commands execute correctly? thanks! - Henk.

11/73 front panel config switches and jumper

by glen.slick＠gmail.com

I recently picked up an 11/73 [M8190 / KDJ11-B in a BA23] and when I finally got around to powering it up today it was failing test 61 Line Clock during power up. I found some info on the H7864 power supply in a uVax doc which says that the BEVENT L signal from the power supply is enabled by the LTC swtich on the control panel PC board. I couldn't find any docs with details on the 11/73 control panel PC board. I can see a three header pin jumper, which has two of the pins jumpered together, and a dual rocker switch. Does anyone have docs for what these jumpers / switches do? Through trial and error I found that flipping the first rocker switch made the test 61 Line Clock failure go away, but for future reference I'd still like to know exactly what the switches and jumper are supposed to do.

SGI IRIS (Motorola) OS wanted

by mail＠g-lenerz.de

Hello list members, I've got an mid-80s SGI IRIS in my collection, an IRIS 3130 in Control Data skins. What I'm looking for are boot or installation tapes that allow me to rebuild a working OS installation on one of the more or less compatible ESDI drives I've got. If someone can help me in this task, that would be greatly appreciated. When I started out with SGIs I almost didn't expect to ever get my hands on an IRIS 4D... a *real* IRIS was beyond all expectations. I've got some kind of inventory and dark pictures of the box online: http://sgistuff.g-lenerz.de/collection/1500.php For some better pictures have a look at Kayas "obsolete hardware" pages: http://hardware.majix.org/computers/sgi.iris/iris3130.shtml#pictures Both IRISes are actually only one machine. On a related note it would also be nice to hear from other IRIS owners in Europe. So far I know of NO OTHER rescued IRIS around here which is somewhat sad, if you ask me. -- Best regards, Gerhard mailto:mail at g-lenerz.de Old SGI Stuff http://sgistuff.g-lenerz.de/

Designing a Classic Computing Library

by compoobah＠valleyimplants.com

>>I was told by two libaries that most of the collection >>would be thrown out durring the sorting and the rest would most >>likely go in a year or two. true of circulating libraries. These have limited space. While most librarians would like to be able to keep everything, you do that at the expense of patron's ease of use and "relevancy" of the collection. If people walk into a library and are confronted by scores of books that you are not at all interested in, they tend to give up and leave. What you want is an archival or academic library. The maintenance of a large collection is integral to the operation of these libraries, and they are unlikely to wantonly cull books. All libraries have a focus. If you disregard the focus it is unlikely that they will be very interested in your collection. OTOH librarians are "information professionals" and recognize the value of information. Ask (a MLS librarian) and they will probably direct you somewhere where your collection will be used (provided they aren't rushing around - library directors are finding out that nondegreed paraprofessionals are cheaper, leaving more work for the MLSes) >And not only that, but in many small communities in the USA there >are movements afoot to merge the public library (as run by a city) >and the school district's library. Key word is city. Larger county and multi-county systems are doing O.K. Not that long ago, Washington had a proposition to eliminate a library district (to "reduce taxes") go down in flames. >The sad fact is that in most places, >where they are funded by the local government, they are only open >now because it would be politically embarrasing not to have them, And you discribe the reason for the existance of most government programs of any value.

Smoke in the Basement

by compoobah＠valleyimplants.com

IRIS x000 series seem to have problems with those junky encapsulated paper caps that like to die. Short answer on how to get the PSU out: take all the skins off- through the top undo the wire connectors, the left-side has the bolts securing the PSU holding plate to the chassis, the right-side has an access port. The caps can be replaced with Mylar units fairly easily.
