[Keeble, Andy] The PSU says something like +6v +12v and -13v. I found the +12v ok, but the other two outputs are showing +20v, so I guess its a voltage reg problem.

I don't know of any stock faults on these machines. [Keeble, Andy] I thought before spending hours, I would ask folks on the mailing list, just in case there were any common problems. I used to work in a computer shop in the early 80's and several makes of machines came in with the same fault. We didnt deal with Newbrain back then, so I didnt get any experience of them. If I get the PSU working, and find I need a schematic, would you be willing to scan a copy and email it, or photocopy and post it (I would pay any expenses). There seems to be little info about the Newbrain on the net, and I guess not that many still exist, so it seems a shame not to try and put some effort in trying to get this one working again. > -tony

Another strange z-80 / CP/M box...

by JRichardson＠softwright.co.uk

Ok, whilst on the subject of big old CP/M machines.. I've got an old Philips P3800 machine, in a grey cabinet about 1 metre deep, maybe 80cm high and 40cm wide. Tracking down any info on it has proved impossible so far; has anyone got one of these they could share information about, or know anything about them? It was damaged in a flood a few years ago, the switchmode PSU in it has failed and just gives a whining noise when power is applied - I seem to remember I tried loading the PSU without connecting it up to the system backplane or drives, so I think it really has failed rather than there being a short or anything within the system. The hard drive (I *think* it was a10MB Seagate full-height, sadly my entire collection is a couple of hundred miles away from me so I can't check!) controller board went with a bang when power was applied - can I simply swap in another board from an identical drive in the hope that this'll work, or are boards calibrated in some way to their respective motors? I tried this swapping with another identical drive and the drive span up ok, so maybe it would work... I don't know what state the data on the drive it in though. Other info needed: Tape drive - mine is missing, having been put in another machine years ago. Anyone know what sort it was, and will the system run without it? Cabling - what sort of terminal could be connected to the cables hanging out the back of the machine? Are they RS232 in which case a vt100 could be used? Was there the concept of a console, or would the machine silently boot? What was needed to boot the machine? Would it boot from hard drive, or was a floppy needed? (I have zero docs and disks for this thing sadly...) Phew! That'll do for now I guess! :*) cheers, Jules

list archives?

by g＠kurico.com

Hi, I just joined this list a couple of weeks ago and it is great. Lot's of great information. I have two quick list related questions. First, is this list being archived somewhere. Just in the two weeks I've been on, it's obvious that there is a huge amount of informational wealth being disseminated. And as any collector of older computers knows, information is the most essential element of collecting (that and software on the proper media). Second, does anyone know of any other lists that focus specifically on collecting? TIA George

Interesting c64 usage

by sinasohn＠ricochet.net

Last weekend I was at a garage sale where I spotted a c64 with an interesting job. It was connected to a mixing board to provide automation. That is, the c64 was used to control the functions of the mixer so as to be able to repeast a setup exactly. Pretty neat, and I wouldn't have minded getting it (I've been lusting after 8-bus multichannel mixer for years) but I couldn't justify the $1300 the guy wanted for it. 8^( Came with an interface box, btw, that had the software in it (presumably in ROM) for the automation. --------------------------------------------------------------------- O- Uncle Roger "There is pleasure pure in being mad roger(a)sinasohn.com that none but madmen know."

Displays needed

by kyrrin＠jps.net

This is a long shot, but what the hey... I have a 10 or so year-old satellite clock that gets its time signals from the GOES birds. It works very well indeed, but some of the display elements are beginning to get dim. It uses seven-segment neon-discharge displays. The first group of three is the day of the year. The next three pairs are hours/mins/secs. The day of year and seconds are the ones that are going dim. Does anyone know of a source for replacement displays of this type? (Are these what Burroughs called 'Panaplex?') Also, Daniel Seagraves has discovered that his RSTS 10.1 tape is trashed. Does anyone else happen to have RSTS 10.x on 9-track that they'd be willing to loan long enough for me to do a bit-copy of it?

That mostly tallies with my memory of my Datamaster (which I haven't powered up in ages). Mine is a 5322, and calls itself System/23 I've never met the 5110 or 5120, I'm afraid. Word of warning: If you have a Datamaster and power it up without the printer it fails diagnostics. However, if you then press the Error Reset (or some such name) key, it goes on booting (into ROM BASIC) quite happily. But what's this in the subject line? IBM never made a Z80 CP/M box that I know of. The Datamaster had an 8085, but didn't run CPM AFAIK; the Displaywriter had an 8088 and ran CP/M86 as an option. (Displaywriter: Much more modern styling. Tilt and swivel screen, separate dual 8" disk unit, separate keyboard. Looked not unlike a PET 8032SK.) Philip.

Teaching Students Computers... (Semi-OT)

by photze＠batelco.com.bh

Hi. This is semi-off topic, but I'm sure that if any replies are made, it'll eventually spin off to someone's tales of their PDP-8 in high school, or their first VIC-20... Anyway, as much as I can complain that I'm not getting a decent computer-education in school, I owe a lot to them. My first year here in Bahrain, I had just got my computer (a blasing fast 486 33!!!), running (what else) Windows 3.1 and DOS 6.22. I didn't know how to type, just use basic functions. I could get on CompuServe (at least in the US), etc. but not do anything "powerfull" I could launch CD-ROMS, install programs since I was 8, in 3rd grade. Then, in school that year, I learned to type. A significant 40WAM. (I thought this was miserrable, but now in typing, many 7th graders got like 19's, 25's...) Anyway, that gave me my basic computer skills. Now, in 6th grade, when I next did serious typing (4th grade was a mess, I skipped 5th grade), I found that my typing increased to 80WAM. (WPM??) Now, I find it's at 100-140. I owe all that to the school. Without learning how to type, I would never have gotten interested in e-mail, programming, computer science, CAD, grapics, number crunching, UN*X, or hardware stuff. Then, earlier on this year, I was asked to help make a computer couse for my grade at school. For the first couple weeks we wouldn't have a computer lab. So I did what I thought would work: Talked about the workings of a computer. Terms like OS, HDD, RAM, CPU, bus, HTML, web, modem, etc. Since then, I've been working to set up a browser-based Intranet. It's been a heck of a lot of fun, if not educatonal. Just my $0.02...

Help Needed: Kaypro 10 HDD Problems

by Marty＠itgonline.com

If all else fails you may want to try a low level format on the hard drive. Boot with a MS-Dos ver 2.10 or later, run debug. At the '_' prompt type in g=c800:5 which should access the controller rom and enable you to low level format (it is <crudely> menu driven). Your Tandon has 306 cylinders, 4 heads and 17 sectors per track. After the low level format procede with the high level partitioning and formatting. -Marty ______________________________ Reply Separator _________________________________ Subject: Help Needed: Kaypro 10 HDD Problems Author: classiccmp(a)u.washington.edu at internet Date: 5/11/98 9:27 PM I recently added a Kaypro 10 to my collection, but it seems to have met with some rough handling in shipping. If anyone can shed some light on the problem described below, I would REALLY appreciate it (any Kaypro experts out there?) When I first fired it up, it booted from the hard drive right away. However, as soon as I tried to access the HD further, all I got were "Bad Sector" errors. Since then, the computer will no longer boot from the HD, and I can't access any information on it ( not a good sign :-( ). Using CP/M, I have tried to re-format the drive with no luck; all I get are "Verify Errors" as it tries to format. So much for the theory that the heads may have gotten knocked slightly out of alignment! Re-seating all connectors on the drive and controller didn't help either. I have pulled the drive from the computer and hooked it up outside the case. It does spin up to normal operating speed, and I can see the head stepper motor responding in a normal fashion when I attempt to access the drive (formatting, parking the heads, pulling a directory, etc.). None of the linkage to the heads seems damaged or broken; in fact the entire computer is in excellent shape and has not been abused. The hard drive activity light (which is controlled from the drive itself) also seems to respond normally. No untoward noises seem to come from the unit when it is operating, although I do hear some metallic "singing" during the last second or so just prior to the drive coming to a complete stop on power down. I'm not sure if this is just the brake mechanism, or if it is the heads against the platters (I do park the drive prior to powering off, though). Based on the above, I am assuming (wrongly so?) that the controller is probably working OK. It is a Western Digital WD1002-HDO. My hunch is that either the drive electronics or the drive itself have failed. Are there any other tests I should by trying? Am I correct to assume that it is the drive which has failed? The drive is a Tandon TM502 (10MB, MFM, 5 1/4" platters). If the drive cannot be salvaged, I would appreciate hearing from anyone who has a replacement drive, or knows of a source for same. I would like to keep the same make and model drive if possible, but an equivalent model would be fine too (as I'm sure Non Linear Systems used more than one make of drive in the Kaypro's).

by dpeschel＠u.washington.edu

... and I wanted to introduce myself. I'm a student at the University of Washington; I subscribed to the list in hopes that there would be some local members. So far, I'm not sure. Some of your names are familiar from alt.folklore.computers but many are new. I'm a computer-science major. Most CS majors here don't seem to be very interested in old machines, unfortunately. They must be dazzled by all the Windows NT machines we have (which were given to us by Intel and don't work very well, thanks to overstressed/inept/inconstant administration). I'll probably read more than I post -- I don't have detailed experience with the popular machines, because I don't _have_ the popular machines, because I live in a dorm room. But I do have experience with the Apple ][, and a Kaypro which I'm resurrecting (thanks to Don Maslin and his awe-inspiring collection of CP/M disks) and some HP calculators and some emulators on my Macintosh. By "popular" I mean "popular with the readers of this list," not "popular with people in general." So... who's from Washington? And BTW, is there a working Web site/archive/FAQ for this group? I can't seem to connect to the bothell machine, even though it's part of my own school. Thanks, -- Derek

Amiga 600HD questions

by maxeskin＠hotmail.com

Would you allow CP/M? BOCHS Unix emulator? Macintosh? I will say only one thing: don't try to go back - it will never be the same, and you will only be disappointed (yes, I know you're only kidding). I don't really use USENET because it's a pain... > >Hell, I was on the Usenet when it was just a partial feed from a >friend at Cal Tech to my little TRS-80 Model 16 two miles away >with its 15-Meg HD that could handle a month's worth of my partial >feed at a time (a full feed would have choked it in less than a >week -- if I could handle the bandwidth) at 1200 baud back in the >stone age (1986-7), when bang-path email could take a week or more >to turn around.

Amiga 600HD questions

by K.J.Whitehead＠massey.ac.nz

I have been given an Amiga 600HD. It seems to work but wont boot. Investigation showed that althought there was a harddrive there was no power going to it. Does the machine use standard IDE drives, if so where did it poer up from, there is no power socket adjacent to the IDE socket on the board. I suppose that a Y cable connected to the supply going to the floppy would work.

RETROCOMPUTING LIQUIDATION

by manney＠lrbcg.com

Well, if someone will send me the 486's, I'll build and test 'em...that's my main business. -- I'm very low on everything, though, so I need your components. manney(a)lrbcg.com "Un sot trouve toujours un plus sot qui l'admire."
