Life with PDP-11's.

by mmcfadden＠cmh.edu

In 1977 I started out with an 11/35 with 4 RK05 drives. System was on one pack, programs on another pack, data was stored on 2 packs. Software was hard coded to look for 2 Megs of data files at a time. When we got the RP04 we made it look like 20 RK05's to the application software. In about 1980 our R&D lab had upgraded from a PDP11/35 to a PDP11/70 system with one RP04. We were in a computer room in the middle of a warehouse, when we asked for more AC they said we could have an additional air conditioner. About a week later a sawsall blade came through the wall of the computer room as they cut a hole for a new window air conditioner. The output side was in the general warehouse space! We were a little mad because nobody warned us about the dust flying into the computer room. We shutdown until the AC was installed. It did cool the room down a lot. Only having one RP04 was a problem. Whenever a backup was scheduled I took the system pack and the backup pack in the back of my Toyota to another computer room a mile away so that I could do a standalone backup. Nothing like walking across the parking lot with the system disk in one hand and the backup copy in the other. I was careful not to drop either pack. Later we thought about getting a VAX 11/730 but decide the 11/70 was fast enough. Mike

ICL7660?

by dickset＠amanda.spole.gov

My ability to search the web is hampered by poor sat comms right now, so I'd like to ask if anyone knows where to purchase an ICL7660 negative voltage supply chip? My Basicon MC-1N is apparently missing it, but RS-232 comms being as loose as they are, I can still talk to it even though there's no negative comms voltage.

Testing a Dead VT52

by Ashley＠carderweb.com

I acquired a dead VT52 DecScope today and I am going to attempt to revive it. I have a copy of the VT52 maintenance manual. I am also getting a second one that "lights up" in about a week. I am hoping to be able to create at least one functional VT52. Does anyone here have any experience repairing a dead VT52 DecScope? When I apply power, I hear a mild hum coming from the transformer area, but there is nothing on the screen.. no cursor, no raster. I just turned it on this evening and have not followed through the debugging information in the manual. One thing I did notice is that the manual talks about a fuse on the back. There is no fuse on mine, but I do see what appears to be a circuit breaker button on the right side near the on/off switch. Any ideas from experienced folk would be welcome! Thanks, Ashley

Stiction (was: Atari TT030 install media)

by dave04a＠dunfield.com

>never mind - stiction it is... I got the bottom board off the drive and >managed to free up the spindle by hand, it now seems to spin up properly >by itself... I have a little story about Stiction ... this is not "cyber legend", this actually happened, and I was the one who did it! Way back, sometime in the mid to late 80's, when this stuff was not cheap or easy to come by, somebody gave me a dead Lapine "Titan" hard drive - I think it was a 20meg drive. The drive just wouldn't spin up at all. I tried the "shake and bake" technique, rotating it back and forth about the spindle axis during power up etc. - no dice, the drive just would NOT spin up. So, "this is trash --- lets look inside". Popped the top off, and immediately discovered that the platters did not want to turn. On closer inspection, I discovered that the head did not want to budge >from the platter surface, and came to the conclusion that the head was stuck to the platter. Memory is a bit dim on exactly what I did, however during my fooling around the head eventually came lose, and I could spin the platter - there was a discolored spot which had been under the head - it was slightly rough due to a bit of surface corrosion or deposits. I don't recall why, but "just for kicks", I took a fine cloth, polished the spot on the platter (IIRC it was still discolored, but I removed the surface deposits). Blew out the drive with a bit of air, and put the top back on, and installed it in a machine to "see what would happen". Not suprisingly the drive spun up right away. So, I low-level formatted the drive and ran a test --- then I got a suprise --- NO ERRORS! This was interesting "I wonder how long it will last", so I left it running surface scans overnight --- in the morning --- NO ERRORS! So I used it for "non critical" data - months went by and I never got a disk error. Eventually I gave the machine to a company I worked for who used it as a lab/test machine, and when I left the place a few years later, it was still going and to my knowlege had never gotten an error. "Clean room ... we don't need no steeenking clean room".

I don't have intimate experience with the TT030 (haven't found one yet), but I believe it has the operating system in ROM, just like the ST series, which I do know fairly well. I do know that with my ST machines, the screen just shows "white" unless there is a diskette in the drive. Then the system will come up. The ST (and I believe the TT) uses a FAT format, and can read/write DOS disks - a blank formatted disk works on the ST, so I'm guessing it might work on the TT as well. Failing that, I do know someone locally with a TT030 who might be able to send an install disk image...

Mac keyboard tunnel software

by cb＠mythtech.net

>Do you >think Timbuktu would lag on a GB ethernet setup? I meant to put this on the other email... sorry. I'm not sure where the lag is happening in Timbuktu. What I find isn't so much a delay in things happening, so much as it is a delay in me seeing it. If I click something that should beep, it beeps pretty much right away... however, if there should also be a window pop open, I won't see the window open until a good half second or more later. And I don't notice that the lag is too much worse over a slower connection (dialup and DSL). So it may just be the way Timbuktu deals with sending the screen draws. Also, it seems easy to get ahead of it. If you move the mouse too fast, it won't show you where it has gone, and then it jumps. So you end up moving slower so you can target correctly rather than constantly jumping around the screen hoping to get the right spot. And you have to click slower or it will accept it as a double click or ignore additional clicks. None of it is that far off. Maybe by half a second. But when you are doing long, repetative things, those half seconds add up fast. Since I can't say that I notice a huge difference in the lag when there is a huge difference in bandwidth, then I tend to think the lag may be elsewhere. Either in the remote machine's ability to processes everything, or in Timbuktu's limit of displaying or sending/receiving the data. -chris <http://www.mythtech.net>

Mac keyboard tunnel software

by cb＠mythtech.net

>Is there any reason an ADB KVM can't be used in this setting? Only because I toggle between the two often. I think flipping a switch back and forth will get annoying. I'm not sure that sliding the mouse across the top of the menu bar won't also... but I just have a feeling that will be less annoying (mostly because I currently use two monitors on my one Mac, and already move the mouse between screens all the time, and I don't find it the least bit annoying, so to me, I just think it will be like having an additional screen to work on, that just happens to have the processing happening on another computer). -chris <http://www.mythtech.net>

Mac keyboard tunnel software

by cb＠mythtech.net

>That doesn't mean there's no lag (you say "because"). Try it over a >satellite link, or a slow dialup, sometime. Oh very very true, over a slow connection. I know I used it in the past over a localtalk network, and it worked without lag. Simply because there wasn't enough data being pushed to be an issue. I'm sure over a slower connection that wouldn't hold true. However, because this software does NOT push the screen image of the remote machine back to the primary Mac... you really wouldn't use it over anything other than a LAN. You need to be able to see the monitor physically connected to the remote Mac to use it. All this does is allows you to bypass using a different keyboard and mouse. >Of course, this does mean that the two machines in question are almost >certain to be connected by a low-latency high-enough-bandwidth link.... Exactly. Since the machine is unlikely to be more than a few feet away, you can use Localtalk at the very least, which in my past use, was sufficient bandwidth (I ran it on a 25 MHz 68040 over localtalk connecting to a 100 MHz PPC 603 laptop... now I want to use it on a 400 MHz G3 connecting to a 250 MHz PPC 603e over 10Mbs ethernet... so I'd assume there will be no lag as well... there is only minor lag in Timbuktu which does FAR FAR more) -chris <http://www.mythtech.net>

I probably should have mentioned in my original post that I am attempting to replace Timbuktu. Timbuktu does a fine job, EXCEPT that I find there to be enough of a lag that it gets on my nerves when I use it thru the day. The software I'm looking for was the software equivelent of a KVM switch, without the V. There was no lag, because all that was being done was sending the keyboard and mouse commands to the remote machine. You still viewed the remote machine on its own monitor. -chris <http://www.mythtech.net>

DEC HiNote Ultra Battery Problem

by matthias.bauchinger＠chello.at

Hello Fred van Kempen, I've seen your post quite some time ago about your problem with the "locked" battery of the Dec HiNote Ultra. You wrote that is was kind of "locked" and that DEC came up with a small tool to "revive" it. I now have the same problem with my notebook. It doesn't charge...even in the small LCD-display at the right of the display-chassis the battery-icon is not displayed. But I can not find this small tool which should bring up my battery again. The url (revive.com) seems to be replaced. Could you please help me with a hint or something? That would be very nice. best regards Matthias Bauchinger PS.: Sorry for posting it to several email-adresses...was not sure which one would work. PPS.: Your old post: Ha! DEC noticed a problem with these battery packs "locking up" after extensive periods of no activity, so they came up with a small utility (revive.com) to "revive" the batt pack. It worked, too.. my battery came back to life, and, after a full charge, is as good as were it new.. ! Lappy is not a portable, ultra-light TCP/LAT/Serial/X11 terminal :) (muhaha, with 802.11b WLAN ;-) Cheers, Fred

I was wondering how much information is around on the microprocessors HP built in the late 70's/early 80's I found some information on the MC2 in the Osborne processor books from '79, and it appears an MC5 is used as the maint processor in the HP3000 Series 44.

Mac keyboard tunnel software

by cb＠mythtech.net

Once upon a time I had a program for the Mac, older program (System 7 era) that allowed you to "tunnel" your keyboard and mouse to another mac. The way it worked was, you would move the mouse to the top corner of the screen, above the Apple menu, and "push" thru to another screen. It would then move your keyboard and mouse control to another Mac. Basically, it worked as a software KV switch (no M as it required you to have a monitor on the other Mac). I've been unsuccessful in turning up a copy of this program in my archives. Partly hampered by not remembering what it was called. Does anyone remember what this software was, and do they have a copy they can send me? -chris <http://www.mythtech.net>

hp proprietary uP history (9825 uP?)

> That's what you'd think but it isn't the case. 9825s in paricular are > nearly indestrucable but I have constant problems with all of the 9845s. In 1979 I did a data-logging project at the Hanford Nuclear Reservation in central Washington. We had 6 or 7 trailers that collected ground water measurement on HP 9825s (using the built in tape drive.) The measurement equipment was connected via HP-IB. The power was from a mobile generator. Every time the air conditioner started the line voltage would dip about 25 volts. This test ran for over a year with out a single failure. I was impressed. In the spring of 1980 the place was thick with grasshoppers. They would get into the equipment it you let them. After Mount St. Helens dumped a foot of ash on the place there wasn't a grasshopper to be found. Michael Holley www.swtpc.com/mholley

Fwd: compaq's portable computer

by dave04a＠dunfield.com

> I think the first one was the Portable (8088 w/ 256k, then the Portable >II (smaller but still 8088 and 640K) then the Portable 286 (286 CPU and >640k(?)), then the Portable III (the small lunchbox sized computer (I don't >remember if theese were 286s or 386SXs)) and then the Portable 386 (it had >a full fledged 386DX). FWIW I have a P-II sitting about five feet from me. FWIW, the Portable III is a 286 machine. I have pictures of mine posted on my site if anyone wants to see one. If anyone has the original setup disk for the Portable III, I would love to get an image of it - the "generic" AT setup disks work in that you can configure the drives and get it to boot, however Compaq apparently "rolled their own" checksum algorithm, as once configured with any of the generic disks, it gets a CMOS Checksum error.

HP 85-86 roms

by desmet＠cnam.fr

Hello, I was wondering if it's possible to use rom dump as binary program (loaded with loadbin), perhaps with some "relocations" ? (I have an HP86B and some CS-80 HD but no EMS roms) Thanks in advance

Restoring a Macintosh Backup

by KVanMersbergen＠RandMcNally.com

I have a tape that contains the backup of a Macintosh 8100. I have tried to use Retrospect to restore it but it doesn't recognize the tape as a valid format. I did a raw restore and the header does mention "Macintosh-BU1" and also "BackUp- 01.74" The tape was made in 1995. Anyone know what program I can use on my Mac to restore this tape? -Ken V. *************************************************************** This E-mail is confidential.

vt220 question

by jwest＠classiccmp.org

Ok, the post from Kevin reminds me of a VT220 question I've been wondering for some time. Is there a "BREAK" key on the vt220 terminal???? I can't find it, nothing is labelled "break". I'm not looking for a key combo that interrupts a specific host platform like ^C or ^P or something, I want to generate a real electrical "BREAK" signal via the keyboard. What is it?

Of course, "Standard" couldn't switch tasks or do much of what people expect of Windoze now (except crash). I recall the day I came back from the Rochester (NY) Hamfest with a $5 RAM board that gave me a whole 1MB on top of my 640K and the chance to turn on the Enhanced functions...

new 8in floppy disks

by chd_1＠nktelco.net

Is there a source for new 8in floppy disks? New old stock is fine. I just would like a box of unused blank disks. Two reasons, first I have a STD bus computer with a Z80 CPU and dual 8in drives (one that does not work) that I might like to play with. Second I have an IBM S/34 that has an 8in drive and I need a box of disk for someone to copy some disks for me... -chuck

Lotus 123 Government Edition?

by rigdonj＠cfl.rr.com

I picked up another load of early PC software last week. Everything was in nearly new condition :-) :-) One of the things that I got was a package of Lotus 123 version 2.01. It's marked as a Government Edition and has an eagle of the disk labels. Anybody know what this is all about? The manuals seem to be standard and don't say anything about it having different features. However I'm thinking that it might be a non-copyprotected version. Joe

DEC VT102 question

by jwest＠classiccmp.org

I have a DEC VT102 terminal that I got some time ago from a listmember. On the right of the keyboard where the numeric keypad is, the keys don't match the color of the other keys on the keyboard. The upper left key in the keypad is gold, and the other keys on the keypad are different colors - red, blue, white - and have editing words on them, I think words like "left, copy, print", something like that. My question is - is it likely that someone scavenged keys from another non-vt100 keyboard to replace missing keys, or was this some option used with some word processing software? If the later, I'm happy I have something unusual. If the former, I am going to yank those keycaps off and scavenge the "correct" keys from one of the other VT100's I'm going to junk. Anyone know the answer? Thanks! Jay West --- [This E-mail scanned for viruses by Declude Virus]

Televideo 910 question

by jwest＠classiccmp.org

My, I'm just full of terminal questions... I have a Televideo 910.. maybe it's a 950 but I think it said 910 on it. When the terminal is just sitting there with stuff on the screen, no data is being sent or received... it will suddenly flip to a "previous screen" all by itself. I don't know if the terminal supports multiple pages of display memory, but the symptom is as if it does support multiple display memory and spontaneously all by itself it switches pages and I see data on the screen that came by a while ago. Can anyone point to a likely culprit that may be causing this? The terminal itself is in perfect mint condition so I hate to get rid of it but this problem is annoying!

Cool stuff!

by rigdonj＠cfl.rr.com

About a month ago I picked up what I thought were a couple of HP-IB disk drives made by a compnay by the name of IEM of Ft. Collins Colorado. I searched the net for information about them but didn't find anything useful. I also posted message here asking about them but didn't get any replies. Last week I got one of my PCs up and running with a HP Hyper Viper card (a HP 9000 300 computer on a card) in it so I decided to use it to check out some of the HP-IB drives and such that have been piling up around here. I found a couple of sites that said what kind of MO disks were supposed to be used in the IEM MO drive but I didn't have the right ones so I stuck in a HP MO disk that I had laying round. It worked! The system thinks the drive is a HP 7935 with 404Mb capacity. Flip the disk over and you've got another 404Mb to play with. Not bad! The 2nd IEM drive turned out to be even stranger. In addition to the HP-IB port it has what looked like a SCSI port on the back. It has a LCD display on and it keeps saying off-line. There are also three buttons on it marked Select, Next and Previous. Pressing the buttons did nothing except make the display say "Next Pressed" etc. I finally turned it off then held down the Select button and turned it on and it came up in a demo mode. It says that it's a "Rewriteable Optical Jukebox Controller"!! It says that it's compatible with the HP 1000, 3000, 9000, etc etc and that it is CS-80 and plug and play with MPE, HPUX, Pascal BASIC, RTE, etc etc. It also says that it supports the C1700/C1701 HP Library System. So it's not a drive after all. (I never opened it up, I just assumed that it was!) That also explains why it has a SCSI connector on it. Anybody here have any experience with optical jukeboxs? I've done a lot of searching on the net for IEM but it appears that they're long gone. I found phone numbers for them but didn't get an answer on either one. I didn't find ANYTHING about the jukebox controler but found a couple of sites that gave cross references for disks that can be used in the MO drive. Of course I'm not using any of those disks but it's working! Joe
