What's an RA90? Can I use one to replace a RA81? Are they removeable? Heavy? Bizarre? How big? The point is, this RA81 is dying and I have a chance to get a RA90. I haven't even seen it yet. Is this worth it? -------

HP Win 3.1 -- off topic, but need help

by photze＠batelco.com.bh

Sorry, but this is just a thought... if HP could give Win 95 LICENCES, and you could find a 3.5" copy of Windows 95 (and the HP's have 8MB RAM), you could run Windows 95 fine. I'm running it on my DX/50 here. Hope that this helps, Tim D.

drive info needed

by jpero＠cgo.wave.ca

All right, guys, After conferring with Allison, we found out thus: > > <Could you check the grounds on one row of IDE pins it's very easily > <visiable on solder side if it's more than 4 pins in middle, it's XT > <ide interface otherwise it's true AT IDE and yeah you can slave this > > All the even pins on the drive are ground, it has the 42c22 chip. I > suspect 8bit (xt) IDE. If mueller is to be believed it's 8bit IDE. This is right, that 93028-A is original pack with ATA logic board but somehow was blown, (Commonly happens), so someone found a good XTA interface logic board from dud 93028-X hd and installed that to this good pack. I suggest you cross out that -A and scribble on a -X? I had so many logic boards of all kinds of Tandon make and WD make, packs were bad too and that shows how high failure rate was with these design. Worst design indeed. Even the same period of time an ST1102A had 150K MTBF compared to those drives with 30K. > <Also, Allison, check that 8 bit card, sometimes it's rare to > <find one > <that will support AT IDE drive on that 8 bit card. > > I have an accutrack isa-8(xt) adaptor for standard ATA IDE it has a > miniscribe 8051A hooked to it. (!!) I have Miniscribe 8051A too. Thermal problem, stays dead but spinning and making funny noise for few minutes then power cycle it, comes up fine. This is only oddball hd I know of that used moving magnet with the coil fixed to the hd case. Snip. > They exist. IDE drives plugged into XTs are no big thing and JAMCO or > JDR has a board for that.

I wish I could learn to make a simple adapter for both 16bit and 8 bit wide, using an ATA drive. So far, I was bit frustrated with some info I found on the net. Did you got good one I that I could understand how to design one? For starter, making a GOOD complete buffered type card with IORDY selectable ATA card for ISA bus? Far as I can understand, a choice of binary setup for first address 10 bits long selects the IDE address beyond that zip. Many cheapo cards have partial buffering which is bad for the IDE chipset. Is this assumption correct? > > I can use an 8bit IDE drive for a CPM system. Then use this that WD 93028-X for this CPM system? > > Allison Jason D. email: jpero(a)cgo.wave.ca Pero, Jason D.

Mac II

by rexstout＠ptld.uswest.net

Just picked up a Mac II for $15, looks like 5MB of RAM or so, 68020 & 68881 FPU, two 800k floppies, an 80MB hard drive with three partitions, and an ethernet card. I swapped out the old Mac II video card since it didn't work with my monitor(64k Mac II video cards from Apple don't do very much) and put my Radius Pivot monitor/card in it, and it works OK now. It's running System 6, so I'll have to upgrade to at least 7.0(i think I have it on 800k around here somewhere) or maybe network it and install 7.1... Also got two "black boxes" for free, one is an automatic RS-232 switcher, and the other appears to be a RAM buffer for RS-232. More info after I figure out exactly what they are... Tonight is going to be busy(upgrading with spare parts I have, looking for info, etc...)! -------------------------------------------------------------- | http://members.tripod.com/~jrollins/index.html - Computers | | http://www.geocities.com/Area51/Lair/1681/ - Star Trek | | orham(a)qth.net list admin call sign coming soon... | --------------------------------------------------------------

More on setting-up Sun3 from tape

by rcini＠email.msn.com

Well, I resolved the tape drive access problem on my Sun3 workstation. Although no other device on the SCSI chain is terminated, the Sun3 does not like the DD50 passive terminator that I have on the end of the chain; it will only access the drives on the chain without it. Anyway, I can now load the tape boot image and start the mini-kernel. Really, the question that I have today is related to the "edlabel" partitioning program. Although the following results from using edlabel, the question is more about disk partitioning in Unix. The drive is a 330mb SCSI hard drive with the following geometry: 512 bytes/sect, 32 sect/trk, 15 trk/cyl, 1254 cyl (as reported; maybe should be 1408 cyls?). Running edlabel reports the following: start c/t/s blks c/t/s type a(root) 0 0/0/0 29297 61/00/17 4.2BSD /* 15mb boot b(swap) 0 0/0/0 0 0/0/0 swap /* swap (would like this to be ~10mb) c(disk) 0 0/0/0 601920 1254/0/0 unused /* disk d(user) 0 0/0/0 0 0/0/0 unused /* user I can create the root partition (and write it to the disk as shown above) with no problem, but I cannot create the swap and user partitions. I get the following error: "ioctl DIOCWDINFO: invalid argument". This is the first Unix drive that I'm setting-up in a non-automated fashion; can anyone give me the benefits of their experience in doing this?? Thanks!

System/34 again

by maxeskin＠hotmail.com

OK, I moved the System into a room where there is light and power. There are no 220V plugs, though. So, I have 2 choices: a)Step-up transformer - how much would 110-220 1700 watts min. cost? b)Using a bunch of PC power supplies to power the DC components. My first problem is how I trick a PC/AT power supply to stay on when it's not hooked up to anything. Do I need to short something? Next is the problem of pinouts on the 34. There is ground and +5v labelled clearly. THere is also a circuit board with lots of screw terminals.

HP 82143A Peripheral Printer

by ds_spenc＠alcor.concordia.ca

I picked up an "HP 82143A Peripheral Printer" a little while ago. It physically resembles the "HP 82162A Printer/Plotter" that is pictured, attached to an HP-75, in a little book entitled "Computer in Your Pocket" which reviews several early pocket and notebook computers. Will the 82143A (the one I have) plug into an HP-75? Will it work with anything else? What kind of battery does it take? Power connector? Pinout of the 12-pin connector? The printer still has a small roll of paper in it (about 2.25" wide) and I wouldn't mind finding out if the thing still works. I got it at a Salvation Army store, and there was no sign of whatever it had been attached to. Doug Spence ds_spenc(a)alcor.concordia.ca

Silicon Graphics Power Series machines available (Chicago)

by eric＠fudge.uchicago.edu

My department is getting ready to scrap two Silicon Graphics Power Series computers. They are both quite dead (parts from the one were used to keep the other going until there were no more reliable CPU boards left) and have been stripped of some parts, but it may be possible to bring them back to life by some magic, or at least to get some use out of the 19" racks and power supplies. If you have any interest in these, please let me know as soon as possible before they are thrown away. They are large and heavy and you will have to pick them up from the campus of the University of Chicago. Eric

Tuning 8" floppies

by dwollmann＠ibmhelp.com

I have a MicroTech ReformaTTer unit with two 8" NEC floppies attached to a PC with the MicroTech FDC. Both drives seemed to be in need of a tune-up (head alignment, in particular) when I installed the unit, and now (this is four yrs. later) I can only read diskettes with one drive, the other just gives me "sector not found" errors. Is it practical for me (me = board swapper) to try to align the heads on these drives manually by trial and error? Is there still a source for the disk required to do it the right way? I have access to a scope if I need one. -- David Wollmann dwollmann(a)ibmhelp.com

"First" key system?

by kyrrin＠jps.net

Sam Ismail typed out... >I have an AT&T Horizon phone system (circa late 70s) which is significant >in the history of telephone systems as it was the first "key" system. It <reaminder snipped> Sam, speaking as an ex-telco person, I can say with confidence that the Horizon was far from being the first "key" system. That honor goes to the original electromechanical 1A system, which was introduced in the late 50's/early 60's. During the early-to-mid 60's, the 1A1 was introduced. It had several improvements over the 1A, mainly in reduced size, weight, and complexity. In the later 60's, the venerable 1A2 key system components were introduced. They endured well into the early 90's, and are still in use in various incarnations to this day (I have a 1A2 system here in the house). The Horizon system fits neatly into the category of 'hybrid' systems. It could, dependent on programming, become either an electronic key system or a small PABX, incorporating the best features of both. Thus endeth key system history 101. We now return to normal topical stuff. ;-) BTW, if you ever want to look for a good home for that Horizon... ;-) -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Sysop, The Dragon's Cave BBS (Fidonet 1:343/272) (Hamateur: WD6EOS) (E-mail: kyrrin(a)jps.net) "Our science can only describe an object, event, or living thing in our own human terms.
