The user may bookmark this page if he/she wishes. Why expose the address at all? How about you send the (plain text only) note on to the addressee w/o disclosing the address. If the recipient wants the sender to know their address, they'll respond to them. The same script could be used if there are any pages on the classiccmp web site where a user could/should have an opportunity to send mail, e.g. to the site maintainer, members listed as contacts or resources for system XYZ, etc. Just a thought, --Steve.

wire wrap strippers

by aek＠spies.com

The only strippers I've ever found that worked well on wire wrap were those ones that looked like small pliers and had white plastic shells that would guide the wire onto stripper blades. I'm not sure who sells these as they were units I picked up at a surplus store. ----- Clauss NO-NIK they show up on eBay from time to time, sometimes listed as fibre optic strippers.

3 P300 printer ribbons available

by jpl15＠panix.com

Last summer, I was at a big ham radio swapmeet in Flagstaff, AZ. There were two of these printers floating around, which, due to size, got dumpstered because nobody would take them... we didn't have room even for one.. and they aren't all that rare anyway. I saved the ribbons out of them, two that were mounted and one (still in it's plastic bag) that was spare in one of the machines. Then I put them in one of the boxed of jun^H^H^H Stuff that I brought back and promptly forgot about them, until the discussion currently running reminded me. SO: Free to someone who *needs* them, you pay USPS priority mail shipping. Two have been used and might probably need re-inking, one is NOS. E-mail me OFF LIST please... first come - first served, and hopefully these should go to someone who is actively using (or restoring for use) one of these printers and can't find ribbons for it. Cheers and Merry Newtonsmas Santa

OpenVMS VAX hobbysit CD

by Qstieee＠aol.com

Also note that while at the Montagar site you ask for two different requests >from a pulldown menu - VMS and Layered products. The Montagar people also told me that the hobbyist CD issue with 7.3-1 is coming soon. Currently the web site says they are out of VAX 7.2 CDs, thus my original post. Also note that a few third party vendors have joined the program, and you can get hobbyist licenses from them also. Even though it says DECUS number on the hobbyist PAK site, you can also use your Encompass US Associate number. Note that Encompass is the HP user group, and that Associate membership is free. There is a slightly confusing point - Encompass associate membership does not get you restricted Encompass web site access, so you will NOT be e-mailed a password, just your Encompass number. So once you have that, proceed to the Montagar site. The Montagar process is efficient; your PAKs are emailed within 15 minutes. The VMS fans on this list should see, for example, http://www.process.com/openvms/index.html Process Software has a hobbyist license for some of their products. They bought up MuiltiNet from TGV. I always though TGV was one of the better TCP/IP's for VMS. For today's trivia, TGV was an acronym for Two Guys and a VAX. Thanks to some help from list member Antonio Carlini, I am now up with VMS and Multinet, NFS, C and a few other items on a VAXstation 4000-90.

Granted, Pennington's book is a good place to start, even though it doesn't cover the differences in Model III TRSDOS. It doesn't help Sellam much, though, if he doesn't have a copy. In my other reply, I gave a pointer to the on-line Programmer's Guide to TRSDOS/LS-DOS Version 6. Here it is again: http://www.tim-mann.org/trs80/doc/prgguide.pdf Although the Guide is denser and not nearly as fun to read as Pennington's book, it contains the same information (and more) and has the advantage of already being on-line.

Does Model III TRSDOS compute the HIT codes the same way as the other TRSDOS-like systems? I don't recall. Since Radio Shack randomly changed so many other things (sectors starting at 1 instead of 0, not having directory entries for the system files, swapping the DAMs, changing directory entries from 32 to 48 bytes, various smaller details), it wouldn't be surprising. -- Tim Mann tim(a)tim-mann.org http://www.tim-mann.org/

Anyone familiar with this one?

by jimw＠agora.rdrop.com

Finally (and I mean it, been trying to get to this one for over a year) dug into an H-88 (H-89? WTD?) that had seen better days (but had this real nice engraved metal name plate reading "HAL") <G>, and where one might expect to find the cassette interface board, I instead found a board with an AY-3-8910 sound generator and MSM5832NS clock chip along with some other bits. Kinda neat. Etched on the board is the legend: Albrektson Sound/Clock H-89 Now, while these chips are familiar enough... Has anyone else run across this board and/or have any software for it? Be curious to see what kind of fun can be had after I get some signs of life out of the machine again. THanks; -jim --- jimw(a)agora.rdrop.com The Computer Garage - http://www.rdrop.com/~jimw

Spamproofing the Archives

by classiccmp＠crash.com

> The way I had thunk it, it would need to be both unique and > reversable. Nope, don't need to. When you add an email address to the database, calculate the MD5 hash and store that with it. Make sure you've got indices on the table for both the hash and the address. When some user uses the form you get the hash back as an argument, form field, whatever. Look it up in the table and you get the cleartext address. Remember the goal is to never put the sensitive data - in this case the email address - where someone browsing the website can get it. > It's not. I have jack-asses posting spam to my VCF BBS and > through my feedback form occasionally. Good point, Sellam. So make the send/confirmation step include the bit where the sender has to input some value from a graphic. Seems like enough to exclude the scripts, provided you're careful about the filenames of images, etc. Remember, you can have another database table that relates the gibberish name of these graphics to the text the sender is suppose to enter. This is starting to sound like a fun little project... --S.

MPF-1 Manuals

by r_beaudry＠hotmail.com

Hello all, I just changed jobs, and the new place has a *TOTAL* lockdown on web browsing, even for the engineers, so I have not been keeping track of the list. I was catching up tonight from home, and saw Adrian's note about me and the MPF-1. I indeed have one, with manuals, and would be happy to make copies for whoever needs them. Please email me off-list, and we can set it up. One small caveat: I have a metric crapload of things going on, so it may be a few *weeks* before I can get to it. If you can wait, I can make copies... :-) Rich B. _________________________________________________________________ The new MSN 8: smart spam protection and 2 months FREE* http://join.msn.com/?page=features/junkmail

PDP11 chips on ebay

by trestivo＠concentric.net

Eric, I saw your post about the chips on ebay, and your right... the seller (me) didn't know you could get a working cpu board for $25. The only prices I could find on these chips online were from retailers and they listed them much higher. So I took a chance at $55. I value your opinion and that of others on the forum. Thank you for setting me straight. Do you know of a source that might help me with pricing? I have thousands of Dec and Vax boards and lots of other stuff that I would like to sell, but fair pricing is tough. I have been told by other buyers that my prices for items sold to them has been great. For instance, I sold a complete working Decmate III on ebay for $49.00, a vr201 for $25, DSD440 dual floppy drives at $185, complete working pdp8/e with 32k memory, rk05 drive, 4 disk packs, monitor and keyboard for $800., 10 pack of new 8" floppies for $15, a tested power supply for a vax 4000 for $25... I try to find as many sources for prices online as I can then set my asking price below the lowest price I can find. I will take back anything I sell that dosen't work and I do my best to test any item before it goes out the door. Eric, please don't think I'm slamming your post! I am apologizing to you and those on the forum for missing the boat on pricing these chips. My intentions are honorable and I welcome all suggestions from other subscribers. All are welcome to visit our warehouse in Florida and make offers on anything they see. I have had visits from other cctalk members and they very pleased with their purchases. You can see a partial list of what we've inventoried so far at www.tarinc.com Thank you all for taking the time to read this. Personal emails can be sent to trestivo(a)tarinc.com Sincerely, thom

Funny, I only remember boring data processing text books, like the one that told us how to use a keypunch and how to interpret punched cards, an important skill when I got to U of Maryland and found that the 029 keypunches in the basement of the CS building often did not have fresh ribbons. (Bill and I attended the same high school, where there was an HP 3000 Series II (upgraded to a Series III in 1980 I think) for administrative and academic use.)

Based on the MicroNotes, I believe you are correct that the switches are used to control the starting and ending addresses. The board, as received, is set to all zero for both. The MicroNote _seems_ to indicate that the ending address should be set to all 1s. However I'm wondering if I really need to set the ending address to 4MB - 8KB (for the I/O page)? Also, there are quite a few jumpers on the board. They may or may not be set appropriately. The MicroNote indicates the function of a few of them, but not nearly all. For example, permit "write wrong parity", etc. If anyone has a copy or scan of the original manual, I'd very much appreciate it. Thanks, John

Spamproofing the Archives

by jss＠subatomix.com

Current idea on spamproofing the archives: [0] Every email address in the archives is replaced with a shortened form. For instance: user(a)domain.com -> user@d... [1] The shortened address is link to a CGI script like this: http://www.subatomix.com/cgi-bin/email?asf3uhh0239q0bs The script generates a page that asks the user to type in a specific string to prove they're human. The query string above is the email address with some some simple sort of encryption. [2] The user types in the string and presses Submit, and it runs the CGI again, but with the typed string as part of the query string: http://www.subatomix.com/cgi-bin/email?asf3uhh0239q0bs,abbabdedf Now the script generates a page with the real email address as a mailto hyperlink. The user may bookmark this page if he/she wishes. Surely this is enough to defeat address harvesters. Does anyone see any problems with this? -- Jeffrey Sharp

You want to feed the free end of the wire through the side that doesn't have the stripper on it. You then push the wire into the groove with a finger nail. If done correctly, you won't have a bend in the wire at the stripper and the wire will not break when you strip it. You'll find that the spool/stripper unit have the same problem. The only strippers I've ever found that worked well on wire wrap were those ones that looked like small pliers and had white plastic shells that would guide the wire onto stripper blades. I'm not sure who sells these as they were units I picked up at a surplus store. As for power wrappers. These require some skill to use as well. With these, one can make a larger mess quicker than using a manual tool. It is all about practice and timing. I've used professional electric and air powered wrapping tools.

Morrow Designs external 8" floppy drive?

by rigdonj＠cfl.rr.com

Does anyone know what system these are for? I've never heard of one before. I had a MD-2 and it used 5 1/4" drives. This is in a biege case about 8" tall x 6" wide x 20" deep. It has ribbon cable header (50 pin?) on the back along with an AC socket and power switch, the drive appears to be a FH Shugart. Joe

Wire wrapping

by dwightk.elvey＠amd.com

Hi I forgot to mention. Use a good sharp pair of wire cutters. If you use some of the cheaper diagonals, they flatten the wire, rather then cutting it. This makes the job of stripping much harder since the covering doesn't slide off easily. Just more of wire wrap lore. Dwight >From: "Dwight K. Elvey" <dwightk.elvey(a)amd.com> > >>From: "Jeffrey H.

Even though a lead-acid battery is fully discharged at 5V. Using it until 5.5V and then recharging is a good idea for longer life. Even if the regulator drops below 5V on the output, most circuits will work down to 4.8V someplace or lower. A low dropout regulator, as you suggest, might still be the best option. Dwight

You need to first start by stripping about .75 to 1 inch of insulation from the end of the wire. There is a built in stripper. Look at the spring steel part in the center of the tool. It has a slit in it that you slide the wire in and then pull the wire from the other side. Now that you have the end, thread the wire from the end, under the small sleeve and along the groove at the side of the shaft. It doesn't have to stay in the groove but make sure it doesn't get kinked or bent badly. Slide the tool and wire over a wire wrap post. Place your index finger at the unwrapper end and twizzle the tool clockwise. This is the tricky part. You need to put enough pressure with your index finger so that there are no opening between wraps but not too much or you'll get overlapped wraps. I also find that the first turn of the tool should have no pressure until the wire has one start wrap. You will also find that you won't be able to twizzle it to completion as one motion. You need to make sure that it doesn't back rotate as you go for another grab with your fingers ( this is where another hand comes in handy ). If you get an opening between wraps, don't think you can just squeeze it down to until it looks OK. This make a loose wrap that will have poor electrical connection. Overlapped wraps should be redone as well. Now, go and practice. You'll get the hang of it soon enough. Dwight

Wire wrapping (electric tools?)

by glenslick＠hotmail.com

Do you have any experience using Standard Pneumatic electric wire wrap tools? 6021 models with bits can sometimes be had on eBay in the $40 range, which isn't a whole lot more than buying a new manual tool.

AS/400 troubleshooting?

by Adrien.Farkas＠Sun.COM

Hello folks, recently (yesterday) I got a new (for me, of course) AS/400 box, and started to play with it. Everything started okay, booted with no problems (after a year unnoticed in the corner). Today a rebooted it (for whatever reason), turned it on, re-connected the twinax console, but nothing appears. The green cursor remains in the upper right corner (meaning that the AS/400 didn't notice the console yet, afaik). Some hints, ideas, places to point me to? Cheers, -- freddy

OpenVMS VAX hobbysit CD

by Antonio.Carlini＠riverstonenet.com

>I believe he meant 'unlimited users' not 'use'. PAKs are limited in several ways (not all of which are used in practice). One typical way was that each PAK would grant a certain number of "units" for a given product. So using the FORTRAN compiler on a relatively slow MicroVAX 3900 series box might require say 500 units, while using the same compiler on a VAX 7000-860 might require perhaps 10000 units (I'm making up the numbers ...). Later on, some products switched to activity based licences. In the above example 500 units allows you as many concurrent FORTRAN compilations as your MicroVAX can stand. With activity based licences, your FORTRAN compilation on a certain platform might eat up 100 activity units so with a 500 activity licence you could run 5 FORTRAN compiles simultaneously. Then there were user-based licences ... In short, it appears that the hobbyist licences are limited only in time (they expire after a year) but will work without restriction on both your MicroVAX I and your AlphaServer GS320 during that year.

UK electronic scrap prices.

by Innfogra＠aol.com

I don't know UK prices but they should be similar to the US. Scrap prices are similar world over in the developed countries. In the US, if it is bulky, without many circuit cards the value ranges from 5 cents per pound (motor breakage, must have copper content) (like power supplies) to 16 cents per pound (Aluminum breakage - mixed Aluminum and other metals) (like hard drives or computer gear with aluminum cabinets) it is sold & bid price is calculated by weight. Aluminum and heavy copper can raise values, especially if they are easy to remove. Heavy circuit cards (with relays or metal bracing) are 10 cents to 40 cents per pound. Poor circuit cards (Like recent PC stuff) 0 to 20 cents. Medium circuit cards (DEC, DG & stuff from the 80s) $1.00 per pound Good cards like (Intel multibus I - 70s, early 80s - lots of black chips, gold chips, old silicon chips.) $1.50 - $2.00 per pound Gold plated cards (like HP) $3.50 per pound & up (depends on age) Cards have to be complete with edge connectors and all chips. Gold chips alone are $8.00 to $20 per pound and sometimes more, especially for old military. Old gold pin backplanes are worth $20 to $50 and up Good (25 pins in a 25 shell) clipped connectors $2.50 per pound. This is what the scrap dealer is going to look as bidding figures. There are deductions for problems related to the bulk of the lot (do you have to rent a truck?) Call a scrap dealer that is not going to bid on the lot and ask the prices for Motor Breakage, Aluminum Breakage, Medium circuit cards and heavy circuit cards. Also the price of Aluminum scrap, cleaned (this means all iron, including screws, removed) Much of the value in electronic scrap is in the a luminum and how easy it is to get out. Someone else will have to convert to British Pounds. Good luck and what is the stuff? Paxton Astoria, OR Ps You can contact me directly if you want help trying to figure out the scrap value of the lot. I am not going to bid on it. Do you have pictures?

Modern replica/implementation of a dumb terminal?

by Robert_Feldman＠jdedwards.com

I have heard of people using an HP LX palmtop (the 100LX/200LX have a fuller serial port implementation than does the 95LX) as a terminal for the type of tasks you mention. The 200LX runs MS-DOS 5.0 on an i80186, so you should be able to get a number of terminal emulation programs that will work on it. -----Original Message----- From: Ethan Dicks [mailto:erd_6502@yahoo.com] Sent: Tuesday, November 26, 2002 1:10 PM To: cctalk(a)classiccmp.org Subject: Modern replica/implementation of a dumb terminal? I was musing about the state of VT100s and other dumb terminals and had a few ideas zing by... <snip> I have used my Palm Pilot as a portable terminal for reconfiguring Cisco routers (VT100 app and a travel cable and the appropriate RS-232 dongles). My boss at the time flipped when he saw me do it (everybody else dragged a laptop into the server room). There are just times when I'd like a laptop-sized-or-smaller ANSI terminal. I can forego double-high/double-wide chars, inverse video and the like for simplicity's sake (hardly ever used them in an app except at the South Pole), but it should be complex enough to run a screen editor (vi or emacs) and/or basic curses apps (Rogue/Larn/NetHack and the like). One place I thought BIOS replacement might be handy was in a sub-486 laptop.... just pull it out, plug it in and *voila*, it's a dumb terminal weighing a few lbs. Yes, it's possible to drop an OS on a floppy and add Kermit (I've already done that with a dual-720K- floppy Zenith 8088 portabie). I'm thinking of a dedicated "instant- on" experience. I also have some "Net Stations" with a 5"x5" 486 motherboard stuffed under a PC keyboard (with 4 30-pin SIMM sockets, IDE, serial, video, and NE2000 network built-in). They don't run off batteries, but neither do they have an intergral screen. I've also tried to think of ways to adapt a Palm Pilot with a permanent keyboard, but I'm not sure there's a way to do it with only one serial port (terminals typically have at least two, even if one is dedicated to servicing the keyboard and somewhat "invisible" to normal operation. The final angle I've worked on is to recycle the main board in a VT220 (being somewhat physically small), but I don't have schematics and I don't know what signals go over the ribbon cable to the PSU/ Analog board under the CRT. So has anyone else wrestled with how to cobble up a portable VT-100? Anyone get any further? -ethan __________________________________________________ Do you Yahoo!? Yahoo! Mail Plus - Powerful.

BIG problem with my Jupiter Ace

by philpem＠dsl.pipex.com

Hi all, I've just opened up my Jupiter Ace and I think the problem I'm having with it is far more severe than a blown CPU. It looks like while I was testing it this morning the PSU was accidentally powered up, the +12(unreg) connection made contact with the barrel of the power jack (-ve) and the PSU's -ve line made contact with one of the first five expansion bus pins on the topside of the board. The CPU was getting very hot - I've since swapped the original NEC D780C (1982 datecode) with a Sharp LH0080 Z80-A-CPU IC. The replacement is also getting hot (takes about a minute for either of them to hit 50deg C). Output >from the 7805 is 5.04V steady according to my Fluke 25 DMM. Video is being output and my TV can lock onto it, but the output is total garbage, no difference if I remove the CPU and ROMs or have them installed. The garbage is always the same, too, in case it matters. The replacement CPU is known-good - it came out of a working Toshiba HX-10 MSX. How should I proceed with this repair? I've got a Fluke 25 DMM and a Tek 466 storage scope at my disposal. Also, the schematics are almost unreadable. I got them from home-micros.freeserve.co.uk. Anyone got a better copy?

It would be worth looking to see if signals look consistent (ie outputs of gates behave in the way you'd expect from what you see happening on the inputs). If you're thinking of replacing every chip at once, or one-by-one, I'd advise against it. You won't be able to tell what's really wrong, and random swapping might just destroy an otherwise perfectly good IC. The 74LS166 is a serial-out shift register, and I expect that's what generates the video stream. Since you say you always get a good consistent picture, with characters (even if they're junk) or some cosistent pattern, the shifter and video timing is working. That's probably where most of your 393's are, too (they're dual 4-bit counters). Am I right in thinking the character set is soft-loaded from the ROM? ie, not in a character generator ROM? Then you wouldn't expect to get recognisable characters unless the CPU can run, and the ROM is OK. Try swapping the memory chips around. If that gives different (but self-consistent) video, at least some of it is working. If it makes no difference, either it's *all* fried or the buffers have gone west. Other obvious things to check are the CPU clock and /M1 lines. The Z80 clock needs to be pulled high, your scope should be able to show if the clock is a nice square wave that goes up to almost 5V (minimum acceptable is about 4.5V, IIRC). The /M1 line goes low once for each instruction fetch; it should be pulsing. The data and address lines should be pulsing. If the CPU is free-running becasue it can't read instructons, it might be executing NOPs or RSTs or just some random instruction, depending on whether the data bus is stuck all-high, all-low, or at some random value. One possible cause of CPU and SRAM getting hot is if the data bus which they're trying to drive is stuck with an active signal. See if you can isolate the bus, and if the CPU or video behaves differently. I'm just giving general advice here, as I've not used an Ace in decades, and have no idea what the circuit looks like :-) -- Pete Peter Turnbull Network Manager University of York

BIG problem with my Jupiter Ace

Video is being Hi 5.04 is an OK value. I wouldn't stick another Z80/780 in there until I knew that there wasn't something else connecting a bad voltage to the processor. You should first power up without the processor plugged in and measure the voltages on all of the pins. Once you've confirmed that there is no +12V or something where it shouldn't be, you can then look for drive contention issues. With the processor removed, find all of the CPU pins that control Writing and reading( I don't have a Z80 pinout handy ). Use pullups to put these into their off states ( no bus activity ). Now check the voltages on the data and address lines. Most TTL cause soft pullups to about 3.5V and any resistor pullup would bring the lines to +5V. These pullups are usually on the order of 5K or larger so you should be able to pull the line down, noticably with a 1K pull down. This will find most any of the issues with some other part that is hard driving against the bus lines. Once you are sure that there is nothing hard driving against the CPU, you could then plug it back in and look for other issues. Just plugging parts in at random would likely be a waste of time and may even do additional damage.

How about ringing a couple up for "very rough quotes", explaining that you have N wotsits, each weighing M kg and see if you can get a ball-park range out of them. Alternatively, bid what it's worth to you - and if you lose, ask afterwards what the winning bid was. What sort of equipment is this? Old PCs or test gear? Antonio

The old 486 I think type chips are worth something like $35/lb (just chips, not boards), so boards get complicated with socketed vs soldered, and gold vs plain chips.

Vintage Ultra-Comp price list

by nemesis-lists＠icequake.net

Hi, well, I've seen some discussions back and forth around here about what things cost "back in the day", with some wildly differing figures at times. In St. Louis, we used to have a distributor named Ultra-Comp, who was in the Earth City area in Maryland Heights (by the I-70/I-270 interchange). So here's an Ultra-Comp price list of 1988 vintage: http://dbz.icequake.net/share/doc/comphist/ultracomp_prices.pdf Enjoy! (BTW, my dad bought the "Ultra Turbo-10 640 system" from them. Upgraded from a Leading Edge 256K 4.77mhz system, 1986 vintage. In 1991, I tasted a 386-40 clone for the first time, and was forever weaned from the 8086. Hehe.) -- Ryan Underwood, <nemesis at icequake.net>, icq=10317253

SGI GDM-20D11 monitor?

by rigdonj＠cfl.rr.com

I found two SGI "granite" monitors for $5 in a surplus place this morning. Does anyone know if these will work with the SGI Indigo? (XS-24 video card.) I tried them but I'm not getting any video and I'm not sure if these are both bad or if they're even supposed work with the Indigo. I checked the SGI and Indigo FAQs and can't find anything about exactly what systems the monitors are compatible with. Joe

Need information on TRSDOS 1.3 internals

by tim＠tim-mann.org

> Does anyone have any documentation on the data structures of > TRSDOS 1.3? Specifically, I'd like to know the catalog structure, > as well as the scheme for storing files across multiple sectors. I used to have that in my head, but it's fuzzed a bit over the years. When I was working for the LDOS folks in 1981, I wrote a program to read TRSDOS 1.3 diskettes and copy the files to LDOS diskettes. I don't know of a place where the TRSDOS 1.3 on-disk structures are written down, though you could try Wade Fincher's manual scans at http://www2.asub.arknet.edu/wade/operate.htm and David Keil's at http://discover-net.net/~dmkeil/trspdf.htm. The general idea is similar to other TRS-80 operating systems. The other systems are well documented (especially LDOS; see my web site), but Model III TRSDOS is different in several ways. Here's a summary of what I remember. Tracks are numbered from 0. The disks are single-sided. Sectors are numbered from 1 to 18. There are 256 bytes/sector. Tracks are divided into allocation units called granules; there are 3 sectors/granule (6 granules/track). You should find the directory on track 17 (decimal). All sectors on tracks *other* than 17 are written with a deleted data address mark (this is opposite from other TRS-80 operating systems, by the way). On track 17, sector 1 has a bitmap to show which granules are allocated. There is one byte per track. There might be a second bitmap to show which granules are locked out as defective. Towards the end of the sector is the disk name and date and the AUTO command (executed if you boot the disk). Sector 2 has a hash table that was used to help search the directory without reading all of it. You can ignore it if you're just reading the disk. The remaining sectors are full of 48-byte directory entries, with the last 16 bytes of each sector unused. The fields are similar to what's described in the LDOS documentation (http://www.tim-mann.org/trs80/doc/prgguide.pdf), but there are some differences in pesky details, like a possible off-by-1 error in the count of the number of sectors in the file. The other main difference is that the Model III TRSDOS directory entries are 16 bytes longer, so that you can have more extent pointers in the entry. Hope this helps. -- Tim Mann tim(a)tim-mann.org http://www.tim-mann.org/

Replacement Power Supply for old Toshiba Laptop?

But, is it possible to >buy a replacement power supply for this? Or, is it >even possible to just hook it up to a regular PC's >power supply? I'm not familiar with this particular machine, but I used to have a similar 286 based machine. A noname tawianese brand, model HL3200 or some such. Designed to look like the Toshiba 3100, but with EGA and an MFM HDD. The main problem with replacing the power supply with one from a generic PC is that the original supply probably had a high voltage output to drive the plasma display. In my 286 machine it was 205V. If you use a power supply that doesn't have the 205V line you'll be able use an external monitor, but not the plasma display. Which would kind of defeat the purpose of getting it running these days. Your best bet would be find a power supply from another machine. One from a 286 based T3200 might do, as may one another machine with a plasma display if you can work out what goes where. It probably won't fit in space where the original power supply was. Either way I'd retrieve the original power supply from the garbage to work out what goes where. I had mine many years ago. I found it in a dumpster with a cracked screen and no drives. This was when back when a 286 with EGA was something special, at least to a 13 year old with no money. I got it running on an external monitor and dumped the broken plasma display. It lived out the rest its days in a plastic case that once held an apple 2 clone, a naked 5.25" FDD and a 30MB MFM HDD at it's side. I completed Leisure Suit Larry 1, Duke Nukem 1, Catacombs 3D and others on this beast before upgrading to a Wang 386-16 (a full size case with room for 2 70MB MFM HDDs with noisy bearings!) and a flaky VGA monitor with serious screen burn. A good used VGA monitor cost around AU$200 at the time so I has to settle for one removed from an old memorex terminal, but I could finally play Wolf 3D.

Solaris 2.4

When I turn the Indigo on, it powers up and plays it's tune so I know that it's started but nothing changes on the monitor. I disconnected the video cable at the monitor and looked for sync on pin 3 and found that there was no sync* unless I started the Indigo with no monitor connected. (The sync was 63.something kHz). If I then connected the video cable to the monitor both the yellow power save and green power lights started blinking. *I don't think the lack of sync on pin 3 indicates a problem. This monitor is suppossed to Sync-on-Green. In fact, the lack of sync on 3 when I boot the computer with the monitor connected may well indicate that the computer recognizes that this monitor doesn't use a separate sync signal. The computer is definitely working. After trying these monitors I plugged the video cable into my usual monitor and everything worked exactly as it's supposed to. I was wondering, if I use a logic pulser and pulse the green input on the monitor will it generate random garbage on the screen? Any thoughts on that? Joe > >ok >r. >

Anybody ever heard of this? I still should have it somewhere around although I didn't use it myself, so I have no practical experience of it. But if anyone is interested to experiment with it, I would try to dig it out one of many boxes in my garage marked with: "interesting things, sort out some day". Frank

Solaris 2.4

by Fred.van.Kempen＠microwalt.nl

> The way I remember this, the first release that bore the "Solaris" > name when released was 2.5 . Nope. They did start with SunOS, the last of which being V4.1.4_U1. When they moved to the Solaris name, SunOS got renamed to Solaris 1.1. The U1 release I have here is Solaris 1.1.2 for SPARC, which _is_ SunOS 4.1.4 with the U1 patch kit. I assume that Solaris 1.1.1 (which I also have, somewhere) is either SunOS 4.1.3, 4.1.3_U1 or 4.1.4 without the U1 patch. The first non-SunOS release I believe was V2.3. I have pretty much all releases of Solaris here, and I seem to start with V2.3, and then up, all the way to Solaris 8. That's when I stopped doing Sun, soo.. :) I lost (read: already deleted) the original posting, so.. can whoever started this thread contact me offlist; we'll get you V2.4 :) Cheers, Fred

Replacement Power Supply for old Toshiba Laptop?

by bwfile＠yahoo.com

Hello, I'm new here, and I've got a problem with an old Laptop. I just purchased a Toshiba T5200 in a flea market, which can be seen here... http://web.ukonline.co.uk/zelandeth/computers/t5200-100/ ...and I bought it for $1! A total bargain, but...unsurprisingly, it's broken...kinda broken. I've opened it up to determine the cause of what's wrong with it, as it won't turn on. A little tinkering later, and, boom, the power supply of the Laptop fries itself up. Damage looks bad, and it stinks really bad...a poisonous sort of smell, so I've thrown the offending power supply to the garbage. Now I have a laptop...with no power supply. But, is it possible to buy a replacement power supply for this? Or, is it even possible to just hook it up to a regular PC's power supply? __________________________________________________ Do you Yahoo!? Yahoo! Mail Plus - Powerful. Affordable.

Xerox 860 IPS looking for a good home

by loki＠visi.com

Hi there, I'm not a member of the list, I found it through a Google search, but I'm trying to find a home for a Xerox 860 IPS that I have. Its been in storage for the last few years in my garage, but as far as I know it works (although I haven't turned it on in a very long time). I have the model with the portrait style screen, and I also have a daisy wheel printer, the system disks, word processing software, and the user manuals. There's even a slew of 8" disks that would go with it as well. I'd rather give this to an enthusiast, rather than just throwing it away. Its really a cool system and I think deserves better than that. I live in Saint Paul, Minnesota, so keep that in mind. This thing is hideously expensive to ship anywhere; it'd have to be picked up. Thanks, Let me know if anyone would like this beastie. Also, because I'm not on the list you should respond to my home e-mail rather than to just the list; otherwise, I won't see your response. -Pat Thielen- _______________________________________________________________ Axolotyl Studios Wildlife, Portrait and Fine Art Photography www.axolotyl-studios.com loki(a)visi.com ICQ #10509612 _______________________________________________________________ "Now that's entertainment!" -Vlad Tepes-

OT - Thinkpad 760CD

by healyzh＠aracnet.com

I've got a IBM 760CD Thinkpad that I want to try and replace the HD with a larger one that I have on hand. After looking over the laptop carefully, and trying to find info on the IBM website I'm left with one important question. How on earth do I replace a HD on this model? Zane -- | Zane H.

Xerox 860 IPS looking for a good home

by Innfogra＠aol.com

This is a classic Xerox Word Processing system from the early 1980s. It should be saved. It sounds like it is a great setup and complete with the full page monitor and printer. It would make a great museum exhibit. We were scrapping these in 1990. There are few around. I may have some of the boot software disks in my storage although this system is complete with software and extras. Paxton Astoria, OR

I have no idea. Unless they needed something more sophisticated or powerful to extract all the data (a collection of still images, video, sounds, cartographic data, geophysical data, text, etc) along with the indexing, in such a way as to preserve the data, its layout, and the cross-referencing. Normal use wouldn't do that. -- Pete Peter Turnbull Network Manager University of York

I also have boxes full (heaps!) of 8" floppies for > this system that I'd like to get the data off and over to a PC It would be helpful if you could identify the floppy interface in the system. It's probably an IBX daughter card. They are probably 1024 byte sectored MFM encoded, I assume for RMX ? HD recovery, as people have said, is more difficult.

It seems to be in pretty good condition, although I don't know if it works as I have not plugged it in. There is one game in the box. Not sure if all the cords are there, but I know the power cord is in the box. (Box is not in great shape). Anyway, if you tell me it is junk, I'll trash it. I've had it for 2 years so I can wait for you to respond. thanks...greg garber -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org * Old computing resources for business and academia at www.VintageTech.com *

Old computers

by gfrajkor＠ccs.carleton.ca

Does anyone have an address and some contacts at the computer museum that NASA's Ames Research centre in California is putting together? There was an article about it in the New Scientist Magazine. Here's the reason: some time ago a museum allegedly building in Colorado approached me about taking away some old machines I have... I promised them, but nothing every came of it and the storage bills are killing me now that I am retired. I will give them away, but I do want to do it on a wholesale basis rather than piece by piece. Here's what I have: Dec PDP 11/34, two RK06 drives (was working when retired). Drives are, of course, the big washing machine ones. 11/34 is in an "executive" rack. Dec PDP ll/23, two RL02 drives, in usual tall rack. Broken pin in ribbon cable to the mini-drives used for booting and diagnosis. RL02s were working when retired. Lots of manuals and some spare platters for the drives. Quick and Timely (Seattle company) CP/M box, S100 bus. Working when last used. Matrox (Montreal company) CP/M box, with old analog-digital conversion attachment, used for scientific experiment data gathering when retired. No documentation, but some boot floppies for the above. Commodore 8296. Beautiful looks. Last Commodore entry into the 8-bit business computer field. With dual floppy drive. Some software. A few miscellaneous Atari STs. monitors, floppy drives. Since I am in Ottawa, California might be a long way to transport the stuff but since some of it seems rare now and the Ames Research centre seems intent on collecting stuff, they might be willing to pay for a truck >from here. I would appreciate advice. ahoj -- ------ Jan George Frajkor _!_ 221 Arlington Ave. --!-- Ottawa, Ontario | Canada K1R 5S8 /^\ aa003(a)ncf.ca /^\ /^\ gfrajkor(a)ccs.carleton.ca h: 613 563-4534 fax: 613 520-6690

Microprofessr MPF-1 Manuals?

The -IP model has a full qwerty keyboard and 20 character alphanumeric 14-segment display instead of just a keypad and 7-segment LED displays so I assume the monitor code would be significantly different. >From: "John R.
