I have no idea of all this sort of info on the S/34. But a lot of it can often be found looking inside the various boxes and subassemblies of the machine. Philip.

Apple //gs boot problem

You say that the drive came from a Mac SE. Did you low level format or re-partition the disk on the IIGS before installing GS/OS? I share a drive between a IIGS and a couple of Macs, so the drive has a ProDos partition and a couple of HFS ones too. Often the IIGS barfs on startup when it comes across the APPLE_DRIVER43 partition map; I find that a Command-Control-Reset sorts this out and the IIGS boots normally.

LCD life

I just picked up a Panasonic PC 7100 ('84 or '85) Lunchbox that works fine, but the backlight's gone. I also have a NEC XT laptop (don't remember the model) that has a screen in beautiful shape, backlight and all.

I got an Apple ProFile hard drive.

by allisonp＠world.std.com

<Remember, all older MFM, ESDI and some early SCSI drives always need <annual or bi yearly LLF job. I have a st506 that I formatted once and never again and it still works fine. I do however run a program that checks it for bad sectors, haven't found many over the years. The need for reformats is urban legend and I have a bunch of RD52/53/54(mfm) and a potload of st506 and st412 drives that haven't been reformatted unless moved to a different system where the controller was incompatable with the former format. However to qualify that I've seen many systems with power down problems where they would write garbage to the disk causeing a need for reformats. I've also seen system with power and heat problems. Optimally the drive should run over a narrow temperature range that is centered at the temperature they were formatted at. most time they are asked to run much hotter and that means the stepper is not centered on the thermally repostioned tracks. This can be made worse by reformatting the drive as cold as it will warm up and all the track centering will be off leading to errors and a likely reformat. Later voicecoil and other servo positioned drives are immune to this as the servo track or embedded servo information will insure it tracks with temperature and bearing wear. Allison

RSTS/E on a PDP-11?

by rcini＠email.msn.com

As part of my recent haul from Temple Univ., I got two versions of RSTS/E. I can't seem to get my PDP-11/34 to read the disk packs. Can RSTS/E be used on an 11/34? If not, does anyone want these packs? Also, the LA100/180 boards and the Printronix boards are up for grabs. Rich Cini/WUGNET <nospam_rcini(a)msn.com> (remove nospam_ to use) ClubWin!

Remember that thread on MFM harddisk noise?

by DSEAGRAV＠toad.xkl.com

This one's VERY interesting... Shop teacher brings up a 486 with a dead harddisk. Opening it reveals a full-height, 350mb MFM harddisk. Atasi model 630. It looks like an RD53, it even has the little spinner underneath that looks like a fan... Anyway, he's got the control cable half-on, and backwards, and the drive params are greviously wrong. So I reseat the cable, set the prarams, connect the power to the drive and power the machine on. Spin up sounds normal, until the heads load... CH-THUNK -BUZZZZZ- CRRARRRGGGH BUZZ- CLUNK - ETC. THe drive sounds like it's come apart inside! But it apprears to be working... So I boot DOS from it and load defrag. Quite a few bad sectors. Defrag gets underway. CH-CLUNK BUZZZZ CRRRAAAARRRGH etc. This doesn't sound good... But the drive is still working fine! It's dancing across the table as it goes, but it seems to be working fine... So now I'm gonna make a .wav of this, this sounds really great... Expect it online sometime soon! BTW, I'm gonna run Norton Calibrate over it, just to see if it's toast or not... -------

LCD life

That is, is there any advantage to having the LCD pixels <all black (or black with a distraction running around the screen) as <opposed to steady, showing the last thing you did? < - Mark LCD life is way out there in hours if one proviso is met at the design level. NONE of the elements should see a DC bias of any sort, failure to meet that requirement insures destruction by deplating the elements and contaminating the LC fluid. High temperatures can be destructive as well. My experience I have a 18 year old 5x7x16 pannel that still works great. Allison

disk equals license (soon: horse flogging)

Yup. >John F.: The upgrade disks require a license to previous software -- you >now essentially have two linked licenses >Is the license bound to *all* of the media? To me, the problem is with the person who finds the software in the dumpster and assumes that equals a license. It's not. The original owner might've even been told by Autodesk to destroy their old media. I can't see why the license owner shouldn't be free to do that, and although I love to read the fine print, I do not recall ever seeing language to that effect. To argue otherwise would only encourage rampant pack-rat-ism. Of course, members of this mailing list don't need an extra dose of that. :-) "James L.

System/34 contd.

Seriously, in most (afaik) homes/schools/offices in the US, it is possible to find 230V between the live terminals of two suitably chosen sockets. But this is not recommended. In particular, you cannot connect the output voltages of two randomly chosen sockets in series and expect the wiring to survive... I'd recommend a 110/220V transformer. They do exist and they are not very difficult to find. It may also be possible to modify the PSU. Don't give up that soon! > "getting started" thing, photocopies would be fun, just to look at... I may have spare copies of some pocket reference guides. There is one for the OS (about 1/2 inch thick) and one for the assembler at least. I shall have a look - eventually! Philip.

9370 is a dog! Was: Re: Re[2]: Firsts

by Philip.Belben＠powertech.co.uk

Sorry to take so long replying - I have been away for a week doing various things (Job interview, visit parents, fail to mend car, etc.). One of the advantages of being away is that a couple of dozen messages after a question I think I could answer, somebody else answers it for me! Far less typing to do! > Certainly more _fun_ than some of the films that have been released for > sure! The wife will not agree though.

Possibly. But I'm not convinced. I seem to remember the biggest IBM 3090 system drew about 250kW (I'll have to look that up too!). I imagine a typical system might draw perhaps 50kW. The biggest problem with this is the supply to your house - few can manage more than 25kW. At 8c per kWh, 50kW is $4 per hour - cheap enough to run for an evening a month, say. > Only one 8 Meg board installed. Maximum, IIRC, was 16 Mb storage. DASD was > probably used as workstation storage. Philip, can you confirm any of this > from your sales literature? If you're interested, William, I can give you > the lineup of PC board modules in the CPU which I briefly talked about > earlier in the thread. 9373 (9370 model 20) was 4 MB expandable to 16 MB; all the others were 8MB, expandable to 16 MB. However, only the 9377 (model 90) had a 64-bit data path; all the others were 32 bit, so I suspect the 4 meg card would work in the 9375. But there's no knowing, with IBM. I see on this page there is a comparison "not fully verified by IBM" by an outside agency, comparing 370 machines with Vaxen. A 9373 is slower than a microvax II; a 9377, rather faster than a Vax 8650, reaching nearly 0.8 Mflop. The 4381 - another low(ish) end 370 - had three models listed, up to around 1.2 Mflop for the model 13. (At least IBM didn't try and claim twice this for the model 14, which is two 13s back-to-back).

LCD life

by mtapley＠swri.edu

All, This discussion got me thinking (uh oh... Danger, Will Robinson!)...is there any point to having a screen saver on a machine with an LCD display? That is, is there any advantage to having the LCD pixels all black (or black with a distraction running around the screen) as opposed to steady, showing the last thing you did? - Mark

MORE Freebies! Come and get 'em!

by kyrrin2＠wizards.net

OK, more freebies! What can I say? I really need the space. ;-) Once again, LOCAL PICKUP ONLY, KENT, WA (Near Seattle). There's no way I have the resources to ship this stuff. 1). At least 20 RL02 disk packs, one of which is the DEC Diagnostics kit for VAX11/730 and 750. There's also an RL02-based distribution kit for the VMS 5.4 upgrade, still in sealed boxes, with the license PAK and release notes. I also saw some RT11 ver. 5.1 packs. 2). A pair of RL02 disk drives, installed in a mini-rack. I'm keeping the Micro PDP-11/73 that was in the same rack, but I'll throw in the QBus RL controller. There may be some documentation I'll pass on as well -- I'll decide that when whoever comes by to get the stuff does so. Drop me an E-mail if you're interested and we'll set up a date. Thanks in advance! -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Sysop, The Dragon's Cave BBS (Fidonet 1:343/272) (Hamateur: WD6EOS) (E-mail: kyrrin2(a)wizards.net) http://www.wizards.net/technoid "Our science can only describe an object, event, or living thing in our own human terms.

Convex C3200 computer (Melbourne)

Another successful "shopping" stip to Temple Univ.

by rcini＠email.msn.com

Hello, all... I went "shopping" at the Temple University Elephant Graveyard again this Friday. Here's what I got, and here's what's left: 1. Misc. boards: LA100 and LA180 logic boards, MDB DB-11, unknown Printronix board (has IM6402 processor, PCB# 104801-002 Rev A. What's that one for?) 2. M7269, M8256, M9312 3. DEC 60833 cable (console cable??) 4. software: DEC 3000 AXP MUP CD and manual (for the Alpha??) 5. IBM monochrome monitor 6. New RK05 filters and head cleaning kit 7. DB-11 and BA-11 manuals 8. PERTEC interface cable (Unibus to ??) 9. Kinetic Systems PDP-11 Crate Controller Model 3912-Z1E (what's this for?) 10. RK05 disk packs: Blank RK05 packs RT-11 System E (??) RT-11 Diagnostics RT-11 V3 SYS RK5 DISK 11/2/77 RT-11 V02C SOURCES 2/12/76 BASIC/RT-11 V01B 12/17/75 RSTS/E V6C RSXRMS LIB RK5 1/26/78 RSTS/E V7.0 RSX RTX LIB RK5 1979 11. IBM Fortran manual {no disks :-( } A quick look reveals that they have the following left (not including two documents/small parts rooms that I *still* have not been able to get to): many 11/23s, two or three 11/34s, many RL01/02 disk packs, several 6' and 4' racks, several ASR33s, boxes and boxes of uncategorized parts, terminals, VMS manuals, TK58 tape drive parts (should have taken them this trip, but didn't), BA23 cabinets, Cipher tape drives, 3 or 4 uVax-Is, several RX01/02 drives, RK05 drives, RL01/02 drives, other crap too numerous to mention. The guy there is taking a full inventory during spring break. Will post the inventory when available. Rich Cini/WUGNET <nospam_rcini(a)msn.com> (remove nospam_ to use) ClubWin!

Disk problems/questions.

<With a 386 computer configured for B: =3D 360KB, a disk formatted in B: <seems fine with no error messages. BUT: running SCANDISK on said <newly-formatted 360KB diskette results in an error message: "Media <descriptor byte incorrect", and prompts for repair. The byte, before <and after repair, is hex FD. Has anyone else experienced this problem? I suspect the following: Disk controller board. Corrupted format program. Corrupted scandisk program. One test not mentioned (or i've forgotten) is do you get the same error on a disk formatted on a DIFFERENT PC? Allison

Does NetBSD use the hardware clock differently?

by allisonp＠world.std.com

<Hmm... are VS3100m30's rechargable or what? Mine always seem to forget <the time after about 20 minutes off... Its 3 AA batteries in a bundle.. It three AAA or three AA (model dependent) NICADS, a source for those are replacement battereis used for some cordless phones. Do not substitute lithium cells or alkline cells as they will fail due to the charging circuit. They are charged with the system is running (12hours minimum). If they have been discharged for sometime then they will be dead. I take them out and charge them standalone. If they don't charge well new ones are substituted. FYI: they only keep the TOY(time of year) clock powered for 2 weeks to 1 month before going flat. The reason for that is not the TOY chip but nicads have lousy long term shelf life. Allison

Commie/Amiga Mouse Compatibility

Does anyone have a spare manual, or a couple of spare cassettes for it? i would like to see what it was capable of. :) Thanks heaps, Adam.

Disk problems/questions.

by wts＠exo.com

If I remember correctly, The 1.2M drive uses a track 1/2 the width of the 360K drive. If you format a disk and write data with the same drive, there is no problem. The 1.2 drive can read down the middle of a 360K fat track and all is OK. The 360K drive can read the 1.2M skinny track and all is probably OK. The problem comes in when you use a 1.2M drive to write on a diskette that was previously written by a 360K drive. The skinny track is now on top of the fat track. The 360K drive will certainly have problems. It will read the new data in addition to 1/2 of the old data.

DEC disk test sets

by jpl15＠netcom.com

With all the discussion of disk exercisers, now might be an appropriate time to post this stuff. I have found a number of DEC and DEC-associated test sets. I have three in my possesion and will wait to see if there is any response to get the rest of the units. They seem to be in good shape, w/manuals and adapter cables. I cant really *test* any of them because I don't own any of the drives they are for. O well..... I have here field test boxes for: RK07/07 TB216A (CDC) (2 available) RM03/05 (3 available) Also there are: DEC TDR Analyzer Wilson Labs SX-530 Disk Memory Exerciser Information Storage Tech. 7330 DDU Tester Memorex 800 Disc Storage System Tester (7 of these available) Memorex Mecanical Alignment Kit Magnetic Peripherals Field Test Unit TB3A2A for RM0 series (3 avail) DEC RM06/07 Carriage alignment tool DEC RM02/3/5 Head Carriage tools (2 avail) Condition of the devices I have in hand appears to be good, the others have not been inspected by me personally, but the owner says they're all about the same. Prices on these units: (US) $50? $75? More? Less? I am in Southern California. These devices are all in 'Zero'-type cases.. shipping should not be a problem. e-mail jpl15(a)netcom.com Cheers John
