Along with the additional UYK-20 computers I found some parts of some AN/UYK-44s. I know that they were used similar to the UYK-20s. Does anyone have any detailed info about them? FWIW they also use core memory. I found that they use the Quadri core memory blocks that I was asking about and posted the picture of about two months ago. Picture at: <http://216.239.39.100/search?q=cache:kY3RwZ-3HjUC:www.lockheedmartin.com/se…> One of the parts that I got was the operator/programmer's console. There's a close up picture of one at: <http://216.239.39.100/search?q=cache:GI46Okw7ah4C:www.newbegin.com/itemmis_…> Joe FYI: AN/UYK-44(V) Computer The AN/UYK-44 computer is the standard 16-bit computer installed in U.S. Navy surface, submarine, and ground C4I platforms. The UYK-44 provides computing power for more than 40 different command, control, communications, and weapon systems. Tactical Systems has been under contract to NAVSEASYSCOM since 1980 and has delivered more than 2,500 computers through September 2000, including UYK-44 open-system modules and enhanced processors.

DEC VT10x and VR201s (was Re: DEC Rainbow)

by classiccmp＠crash.com

> > review claimed the VR201 was compatable with the VT102. > > Considering the former is a composite mono monitor and the latter is a > terminal, that's just impossible. I seem to recall that many/most VT100's had composite video out - mine do - and this was frequently used in the classroom to drive a larger monitor, or distributed to several monitors/terminals throughout the classroom. This way my Data Structures professor could show us *exactly* what she was on about. Perhaps there was an adapter to use the VR201 in this manner? I can remember staring at the displays, but not what was rendering them. I know she was working on a VT100, but can't "see" the slaved monitor in memory... --Steve.

But other people use OE without these problems. My mailbox currently contains 47 messages created with OE, including some from at least ten other listmembers, and only yours have the UTF-7 problem(s). Some are version 4.72, some 5, some 5.50, some 6.00, etc. I even found several with exactly the same version you have (5.00.2615.200), so it looks like there's something else in your setup that's making OE prefer UTF-7.

One for current, one for default, and maybe something for per-recipient preferences (as in "this user prefers to receive fancy text" or something similar)? -- Pete Peter Turnbull Network Manager University of York

FY Sellam MS OE

by allain＠panix.com

(It means "For You", yes. yes, that's what it means <g>) For those wondering where my bad escape sequences came from, or why, here is a partial explanation. I used to get ISO encoded messages when I originated a message to Classiccmp and UTF-7 encodings ($ = '$', = = '=', _ = '_', etc.)** when I used "Reply". A while back I noticed that sometimes after setting an encoding and sending to the list that the encoding was lost to UTF-7 anyway. This was about the same time as the list software change so back them I assumed incorrectly that the new software was setting UTF-7 headers (Content-Type: text/plain; charset="utf-7") and loosing my ISO ones (...charset="iso-8859-1"). Now it seems that the way the setting was getting lost was by saving and recalling message drafts in MS OExpress. It is very possible that there are other ways MS will mess this up but for now I think it's fixed. FYI here is my file entry on the subject. "List of Encoding Problems with Outlook Express: You can't shut off charset encoding. (Two choices: MIME and UUEncode. There is a "MIME: encode text using None" option which doesn't work, it still encodes.) You can't set an encoding 'for once and for all'. There is no clear indicator of the encoding in use (have to go down two menus to check/set each message). Selecting a useful encoding [Western European (ISO)] results in display using an undesirable proportional width font. Manually selected encodings are easily lost and overridden to UTF-7 (example: set ISO, save as Draft, recall, send, it will be UTF-7**) The appearance of an encoding is buggy; what appears when reviewing a saved message is sometimes decoded, sometimes not, with the same message. Can't check a message header on an unsent message." so Sellam aggravation is nothing compared to this <g> If somebody wants to help, why is one of my messages today (Sunday, November 03, 2002) 1:07 PM, BBS..., about Panix, appearing as proportoional font and 1:53 PM, about vcfban.gif, appearing as fixed width font, to me anyway. MS-UGH! John A. ** hope this displays correctly, the sequences will probably be lost.

Is > the problem something that is being generated by John's backquote, or am I the > culprit? No, it's John's mail client. It's not just the quotes or whatever is being used to indent the quoted text. It's anything that isn't flat 7-bit ASCII, with some characters reserved to allow encoding. For example, the line > +ACo- +ACI-Data Explorer, from the IBM +AF8-Deep Computing Institute+AF8AIg- contains 4 different escape sequences, one of which is 8 characters long! UTF-7 is a coding system designed to handle Unicode (which is normally 16-bit or 20-bit) by using escape sequences to encode non-ASCII characters in a way similar to the scheme base64 uses for whole chunks, and intended only for use on 7-bit systems that can't handle 8-bit data. > OE 5 has several choices for indent on replies... I am using '> '. If John is > using ': ' or '| ', (the other 2 choices), they might be getting read as > something else by your MUA, and changing the indent might eliminate the problem. > What MUA's are you guys running? The text appears with the wierd escape sequences on loads of MUAs, in fact probably most of them. Very few MUAs support UTF-7, because it has inefficient compression, there are other encodings that are more versatile, it's more awkward than most to program, and it's a one-to-many transform (for any given string, there are several possible encodings) so it produces unsearchable text. And since it came along later than the other common encoding schemes, and doesn't do anything the others can't, I suppose there was an element of "why bother?" If you look up Unicode and UTF-8, you'll find dozens of common applications that support it (and UTF-8 is the accepted standard for a whole load of things defined in RFCs, as well as the mail internationalization report >from the IMC) but the only application I know of that definitely handles UTF-7 is Outlook. Quote from the IMC report: "Fortunately, very few vendors implemented UTF-7, and its use is strongly discouraged in Internet mail." The solution is to turn off the UTF-7 character set, use ISO-8859-1 or UTF-8 or something else that's commonly accepted, and then use a standard content-transfer encoding, like quoted-printable or base64 if you have to make it 7-bit-safe. -- Pete Peter Turnbull Network Manager University of York

Some more info on the Philips P3800, and P4500

by julesrichardsonuk＠yahoo.co.uk

Will, > I came across a site today which provided more information on this critter, > and as Fritz had suggested, it is indeed a TurboDOS machine.. I have a copy > of TurboDOS around, but I don't know if Philips used a custom version or ? no idea on the data front. Did TurboDOS have built in multi-user support (I know nothing about it)? If not then I'd definitely think that the version on this machine was custom, as it has support for at least 4 if not 5 terminals in its current state. That's just going by the cables at the back; there's a lot of unused pins on the card edge connectors, so given that the website claims support for 62 terminals I expect it could make use of some breakout box arrangment to give more 25-pin terminal connectors. > Not to mention that I don't have a clue how I'd copy it, or even what > TurboDOS runs on. Here's the link I found to the info on the P3800: > http://www.digidome.nl/philips1.htm unfortunately I hit a bit of a snag with my machine. Following the flood damage the previous owner had tried to fix the system. Trouble was, the machine has two backplanes to it - the upper one with one row of card sockets and the lower one with two rows. System cards from the top rack will also plug into the bottom rack (which contains the PSU, mains voltage, and a spare slot for some unknown board). The disk controller had been plugged into that spare slot... :-( It wouldn't have got any mains voltages but it would have got +5 and +12V on all sorts of pins that it shouldn't have. I also found that the disk data bus (SCSI? SASI?) terminators had been misaligned and so it's possible some of the data lines were shorted together or at least had a low resistance connected across them. Curiously, the disk controller and the board the converts the system's SCSI/SASI bus to MFM look to be identical on the P3500 (from the photos on the website that Fritz posted about). So if one of those ever shows up, at the very least it'd be invaluable for checking that the hard drive on this 3800 is still operational - and in the absence of schematics for the 3800 it'd probably be very useful for fixing the 3800's disk controller. > Also, the P4500 is a minicomputer of some kind, apparently.. I'm not sure - I did a quick hunt on the web and there was very little information around. One site seemed to imply that it was much older technology than the 3800, but another site gave the impression it was much newer. Uless the model number was reused they can't both be right :) cheers Jules __________________________________________________ Do You Yahoo!?

I show a lot of respect for CRTs when handling them! I had to remove the deadly-looking bare PSU mounted on the drive enclosure in order to work on the drives, so it also got the kid-glove treatment . . . What I meant by gotchas was: anything troublesome about the serial or parallel i/o? Any known bugs in the ROM? The manual very nicely documents the ROM routines (if the book is accurate) so this thing should be fun to do some assembler programming on. So far, despite all I've heard about "trash 80," this system looks pretty friendly. Later -- Glen 0/0

avail: ATARI Hitchhikers Guide disk

by rschaefe＠gcfn.org

Pulled a 5.25" floppy out of an old PC clone I picked up. It's an original `The Hitchhikers Guide to the Galaxy'. Got a number on it: IS4-AT1-FD1, and -FD2 on the flip side. I dunno what condition it's in, but there's no mechanical damage and no write-enable notch, so there's a reasonable chance that it hasn't been reformatted into a PC disk. Anyone want it? Bob

Hi everyone, I am new to the board, and hope you might be able to help me figure something out. I have bought locally and resold old computer items over ebay, and I have come across what looks to be an old Honeywell dummy terminal, with keyboard. Here is a link to a pic: http://server3001.freeyellow.com/maddog1331/honeywell.JPG What I would like to find out is exactly what I have here, what it hooked into, what kind of value, when it came out, etc...I have checked on the net but have came up with nothing on this. Any help would be greatly appreciated! Sincerely, Mark Saarinen Kentucky, USA

DEC Rainbow

by kenziem＠sympatico.ca

I picked up a rainbow this evening, but it is missing the monitor and keyboard. But there was 2 floppy disks still in the drives. I've looked the case over and the only ports on the back seem to be the video, printer and COMM. If I connect a VT-100 to COMM can I still access the CPU's?

Best version of AIX for my RS6000

by ceby2＠csc.com

Brian -- > did you upgrade from 4.3.3 to 5L on the 591? i've currently got 4.3.3 > on my 591 and was wondering if it was worth upgrading to 5L or not. Yes and no. I started with 4.3.3, but when I upgraded, I did a build from scratch. For most uses the upgrade isn't that worthwhile. The GUI tools run even slower than they do in 4.3.3. And there's no great differentiation in software compatibility. The real bonus is linux compatibility libraries. I don't compile much on the AIX machines, so I'm less concerned. Mine get used as administrative workstations...and...er... and as a mainframe. The 591 has the P390 card. It's my sandbox for OS390, something I don't know a lot about but have a consuming curiousity for. The real reason I keep them current is to keep me current. -Colin

Bringing up a 10 years dormant VAX 11/750

by jwillis＠arielusa.com

Ok, the rodent issue is dealt with. Everything has been taken apart (and documented), cleaned thoroughly, and put back together. Now I'm completely lost. Plugging it in, the large orange light on the PSU lights up. With the switch on the PSU switched to "LOCAL" and the breaker turned on, the blower kicks in. Thing is, I don't have a key for the front panel power switch. However, James Lothian's 11/750 FAQ says that the power supply being switched to "LOCAL" should override the key setting and power up the machine, but the power light on the front doesn't light up, nor does anything else. On the PSU, there are no failure lights, but "Power OK" doesn't light up either. Any thoughts? John

OK, I think I've stepped in it... (MICOM 2000)

by lgwalker＠mts.net

Aarghh !! Actually its about the same size as a Commodore Pet. The 8" Shugart FDD is about 4" high and the same size as the base. What might possibly push up the weight is the Qume power supply for the printer. The printer itself is the fastest daisy-wheel printer I've seen, tho a bit noisy, and could likely be interfaced with other computers. The massive printer power supply could also be used with a homebrew adaptor for a variable power supply. Since NASA had it tied into their mainframes as a stand-alone workstation it could likely be used as a terminal with the async card. Try it out before passing on it and please let me know what docs, programs and cards it comes with. Maybe we can work something out.

Performa question

by cb＠mythtech.net

>Does anybody know if I can duplicate it on a CD-R on a PC? Maybe, if the PC software allows for direct unmounted drive to drive duplication. Toast on the Mac can do this, so I would think EZ-CD on the PC can do it too. Nero probably can seeing as it supposedly can duplicate Playstation CDs (which usually have parts that can't be properly read or mounted on a computer). >Should I be able to read it with Windows Explorer? No, the CD will be in HFS format, which is a Mac format. If the person has one of the PC utilities for mouting Mac discs, then you probably can, but without it, no it won't be recognizable. (thus why for the above question, you need to be able to copy the data without it being mounted) -chris <http://www.mythtech.net>

What is it ?

I recently acquired a rather aged Compaq "portable" that defies identification, the plate says Model: Compaq, Serial number: 002027. Size is 19 1/2 wide, 15 1/2 deep, 9 1/4 high with a 8 in "green screen".On the right side to the rear is a sliding cover over 5 slots, 3 filled, the left side slides open to expose the fan and switch and provides power cord storage. It has two 5 1/4 360k drives. The keyboard locks over the front for transport and it has a leather carrying handle on the back. Can anyone provide me any info on this machine Am also looking for info on a Kaypro 16, Dos machine Thanks, Rich

I believe the logic board is labeled as such, and they are pretty rare, so odds are you won't have one. But it might be worth a quick look at the board to be certain (IIRC, it is labeled "Parity" near the SIMM slots). As long as you don't have that odd version, then parity or non parity will work fine in the IIci (but I recommend you keep them all the same type) -chris <http://www.mythtech.net>

MAC LC, LCII & IICX

by cb＠mythtech.net

>Question: when you find a good software package on a +AD4-7 >year old Mac, is it easy, hard, or completely impossible >to add said software to another Mac that you have. >This assumes a working network for starters. Most software on the mac is VERY easy to copy from one mac to another. In many cases, all you need to do is copy the folder the application is in to the other mac, and you are done. Everything is contained in that one folder. That is normal Mac behavior. Some applications have support extensions however. In those cases, you will need to also locate the appropriate files from the System folder. (usually in the Extension folder, but depending on the purpose, may be in the Control Panels folder, or elsewhere in the System folder... ie: Claris applications make their own folder called "Claris" and stick most of their support files in there). If in doubt on what may need to be moved, feel free to ask, I might be able to tell you if there are any additional files and where to locate them. -chris <http://www.mythtech.net>

MAC LC, LCII & IICX

The LCII is crippled with crappy hardware design. IF they are populated with max RAM and bigger hard drives they might be worth alittle more. Chances are they have maybe 8meg and 40/80meg hard drives. The IICX has no built in video either.

Bringing up a 10 years dormant VAX 11/750

by xds_sigma7＠hotmail.com

I didn't mean to imply that I thought it was.. I was laughing about what Fred said the tombstone would say for someone killed by their 11/70.. My apologies if you thought I was laughing about that... I agree with you fully about the danger of hanta virus... Any time you are around rodent excrement, especially in large quantities, you can't be too careful... That's why I have thrown out a few items I've gotten over the years; I figured the potential health hazard to myself was not worth it... A good example would be the Sinclair ZX-81 I got which was filled with cockroaches! YUCK! What sort of protection do you think would be adequate for John when he cleans the VAX? I'd almost want to recommend some kind of serious respirator-type mask, like the ones used when you do things like paint a car, or work with fiberglass, etc. But I definetly agree you should, bare minimum, wear a face mask, and gloves as well...

Build your own PDP-8!

by bob＠jfcl.com

In about twenty four hours eleven people have signed up for 13 PC boards. This is far more than I ever expected, and I'm glad to see so many people interested in PDP-8s and the SBC6120. I plan to keep taking sign ups until Monday, or we get to 20, which ever is first. BTW, the number of people signed up for our cooperative so far is enough to guarantee a PCB price somewhere in the low $30 range.

What is it ?

by Innfogra＠aol.com

Sounds like the original Compaq portable, one of the computers that "made" Compaq. The Compaq Portable II usually said that, it was a bit smaller and had 1.2 floppies. All the others are smaller. Does it have a hardcard installed in one of those slots? Does it boot? Paxton Astoria, Oregon

Hi I know this doesn't make sense at first but it is most likely that the failure is in the HeNe tube and not the power supply. The general failure starts with the lasing pulsing at slower and slower rates until it stops working. The problem is caused by the He leaking out of the tube. I know you'd say, how can that happen when inside the tube is a partial vacuum. Well, it has to do with partial pressures. The partial pressure of He is lower out side of the tube than inside, so it leaks out. It is also related to the slipperiness of He. It leaks through everything, including glass. Try another tube that is known to be good. Dwight > >I'm just looking for general guidelines. > >Thanks! > >Pat >-- >"The Microsoft/IBM FORTRAN was adequate for teaching FORTRAN 77.

Hazeltine 1421 - anyone heard of it?

by ian_primus＠yahoo.com

I just got a Hazeltine 1421 terminal. When I first got it, It showed nothing but garbage on the screen, then I took it apart and cleaned everything, reseated chips and cleaned their pins. I fired it up again and it worked perfectly, save for the keyboard jamming on some keys. I cleaned the keyboard completely, and was able to fix most of the problems, except the keyboard is missing the "-" keytop, the "T" key jams occasionally, "E" is erratic and "J" is really gouged and bent, and falls off easy (looks like someone dropped something heavy on the keyboard). All in all, save for the keyboard, it's in very good shape. The question that I have is wether anyone has heard of or seen a Hazeltiine 1421. I haven't been able to find anything on the internet, but I did find the Hazeltine 1420 manual on vt100.net. Linux doesn't seem to have an entry for the 1421, but it does have one for the 1420. Inside the access panel is a switch labelled "1420" and "Other". I have tried it on "1420", and told Linux that it is a 1420. It is barely useable. No programs will display properly, things like pico and pine get really screwed up, not clearing the text from the screen when they write the next screen, etc, even screen seems to do funny things to it, sometimes after exiting programs or typing "clear" the prompt appears in the middle of the screen. I am guessing this is either due to the termcap or terminfo(what's the difference, I always forget?) entry, the settings on my terminal, or maybe the programs I am trying to use aren't meant to deal with a Hazeltine terminal. I would appreciate any information anyone has on this terminal. Thanks! Ian Primus ian_primus(a)yahoo.com

O-scopes: probes, tutorials

by classiccmp＠crash.com

A couple weekends ago I finally made it to the Flea at MIT - only been meaning to go since 1989... Anyway I was looking for a vendor and wound up watching an exchange between a different vendor and this guy in a corduroy jacket. The short of it was, this vendor was desperate to not have to load all the Tek scopes he had back into the truck. Corduroy boy was balking, and the vendor only got more flustered when he was asked if the scope could be hooked up to a stereo to do something cool ;^) So I watched this play out. I'd been thinking I should pick up a scope, as I hope to start tinkering with hardware again sometime soon. But I was thinking about some simple dual trace 20-50 MHz unit... What I got for $100 was a Tek 7834 Storage Scope on a Model 3 cart. With the following 4 plugins: 7A22 differential Amplifier, 7A26 Dual Trace Amp, 7B85 Delaying Time Base, and 7B53N Dual Time Base. And upon getting it home it did, indeed seem to work. Of course I have no probes or manuals, but I got traces and labels and whatnot on the screen. Calibration? Who knows... Anyway, I was wondering what my options are for getting some probes for this beast. Things show up on eBay, and I'll keep an eye out there. There's a local shop that has Velleman probes tho I don't know for how much. Where do you go for probes? Also, anybody have a preferred instructional source, "Using O'scopes For Fun and Mayhem" perhaps? Thanks, --Steve.

[poss OT]: WTD: (UK) NTSC-to-PAL module or NTSC-capable monitor

by philpem＠dsl.pipex.com

Hi, I've just finished building a COSMAC Elf and I've hit a major stumbling block. The CDP1861 video chip outputs monochrome NTSC video. Unfortunately all the monitors I've got are PAL, VGA or SuperVGA. Soooo... Has anyone got an NTSC-to-PAL converter for sale (or can suggest a possible source)? Or maybe even a 5" to 9" NTSC-capable monochrome or colour monitor? If the latter, a vertical hold control would be useful, but not essential. I can get composite video (combined video+sync) or separate Csync/video (luminance) at 5V/0V CMOS level out of the 1861, whatever is needed. Thanks. -- Phil. philpem(a)dsl.pipex.com http://www.philpem.dsl.pipex.com/

halloween thoughts

Being that it is halloween, I got some candy to pass out to trick or treaters. I also thought that it might be an opportunity to clean out my junk heap... <ding dong> "Trick or treat!" "Here you are, there's one for you, one for you, and one for you" "But what am I going to do with a 2400 bps modem?" "I don't want a broken disk drive!" "Can't we have some candy?" "Sure, if you take this broken monitor..." Ok, maybe not. How about drawing eyes and a mouth on a broken monitor... a Jack-o-CRT? Or maybe I could try giving away AOL CD's... Computer parts go pretty well with other holidays, broken 30 pin SIMM's make pretty good Christmas ornaments, and as a tech I knew once said, it's a good idea to keep a stack of greenbar around so that on Saint Patrick's day, so that you can go someplace to drink... a green bar. <har, har, yeah I know it's pretty bad> Sorry, I couldn't help posting this (retreats into corner).

LSI-11 WCS and MICROMs

by mbg＠TheWorld.com

>I just realized that my reply to Jerome's inquiry about the >LSI-11 module with five chips was probably wrong.

So the original quad-height >LSI-11 module would have four 40-pin chips without the EIS/FIS, >or five with.

Actually, I've seen the dual microm used on both 11/03s and on 11/2s, as well as on the PDT (I have a couple of those which have been so modified). The 3007/3010 chips are combined into one dual microm. This would allow boards with only 4 sockets (like the PDT) to add EIS/FIS. >On the 11/23 and 11/24, some of the chips were also on dual-chip >hybrids. The FPU chip for the 11/23,24 was a dual carrier chip. The CIS option was a hex-carrier chip. It had 6 of those small gold chips on it, and spanned two sockets of the 11/23[+] board. I don't know if it could go on the 11/24. (I have a KDF11-B with one of these chips on it).

LSI-11 WCS and MICROMs

by eric＠brouhaha.com

I just realized that my reply to Jerome's inquiry about the LSI-11 module with five chips was probably wrong. IIRC, the LSI-11 chip set consists of the control chip, data chip, and two MICROMs for the base instruction set. The EIS/FIS (KEV11) is a single additional MICROM. So the original quad-height LSI-11 module would have four 40-pin chips without the EIS/FIS, or five with. Was it the LSI-11/2 half-height module that sometimes used a hybrid with two MICROMs? If so, it was probably the two microms that implemented the standard instruction set, in order to leave a socket open for the KEV11. On the 11/23 and 11/24, some of the chips were also on dual-chip hybrids. Eric

VCF East 2.0...

by classiccmp＠crash.com

[ I can't seem to reach the nameservers for vintage.org, but this ] [ could just be me since no one else's complaining... ] I don't care where it is on the East Coast, though the closer to Boston the more likely I am to exhibit my few paltry items. Suddenly much more likely thanks to the acquisition of an older Honda Passport SUV... This'd be an incentive to get the VAX-11/730 running again. That'd make a nice, compact display if I don't kill myself trying to move it. Or if I could squeeze more than 2MB in along with a UDA50 and tape controller... I know, I know, it isn't as interesting as the pdp-11/40, but all I have of that is the front panel with some TTL that uses the address bit LEDs as a binary counter. (And no, I did _not_ butcher the machine, I found it that way.) Hey, if I also finish cobbling together my pdp-11/73 in a BA123 box I can show how much faster _and_ lighter it is than the 730... >^) --Steve.

Looking for Symmetric 375

by classiccmp＠crash.com

> It's kind of an odd thing, but does anyone have a Symmetric 375 > box that they want to pass to a good home. Well, a while ago I was soliciting ns32k hardware of all sorts and while the Symmetric was mentioned as an example, no one was offering a unit for sale, trade, or otherwise. I don't recall anyone having production numbers, but "few" seems appropriate... Darned shame, it's a very fine looking box. I'd love to have one, as I'm sure would at least a few others. --Steve. PS - Thanks to all who responded to that earlier thread, esp. David Fellows and Al Kossow.

360K drives

by dlormand＠aztec.asu.edu

I'm trying to help some guys outfit TI-99/4As with 360K drives. A year or so ago, they were still available from some of the surplus dealers I know about, but they seem to have disappeared. Does anyone have a line on supplies of 360K drives? The only ones I find via web search are $25, which seems a bit much for a once-ubiquitous drive that is now a little obsolete.

Dynalogic Hyperion

by lbutzel＠attbi.com

Mark - Saw your note on classiccmp.org re the Dynalogic Hyperion. I have several of these machines as well as some diagrams and parts lists for them. Two of them have a problem in their video circuits such that their screens show nothing nor is there a signal out of the external monitor RCA plug, yet the computer will otherwise continue to function normally. I have been looking for some guidance on how to track the fault down and fix it but have so far had no success. Any thoughts? Regards Leo Butzel lbutzel(a)attbi.com Seattle, WA

Build your own PDP-8!

by bob＠jfcl.com

If you're one of those people who wants a PDP-8 but can't find one, don't despair - you can always build your own! The SBC6120 is a complete PDP-8 built around the venerable Harris HM6120 CPU and modern programmable logic devices. All parts used except the 6120 are contemporary, easily available devices. The entire system fits on a PC board 6.2" by 4.2" and has approximately the same footprint as a 3.5" hard disk. The SBC6120 has an IDE disk interface, an optional 2Mb non-volatile RAM disk (that's as big as an RK05!), and a true KL8/E compatible console terminal interface. OS/8 device handlers are available for the IDE and RAM disks, and the system will run standard OS/8 V3D. There's even an expansion bus so you can design and build your own daughter cards to plug into it. To find out more, visit the SBC6120 web page at http://www.SpareTimeGizmos.com/Hardware/SBC6120-2.htm I've recently had two requests to buy SBC6120 PC boards. These are four layer boards with plated holes and are quite expensive in quantity one or two, but the price falls per piece falls dramatically for quantities as small as four or six. I'd like to find a few other people who would be interested in building their own SBC6120 and going in together on a PCB order. The price for a SBC6120 PC board would be something like: Two boards ==> $100 per board Four " ==> $60 per board Six " ==> $45 per board Ten " ==> $36 per board I also have about four spare 6120 chips, which I'm willing to sell at my cost of $50 each. Believe it or not, it is still possible to buy new old stock 6120s, at $50 each, with a minimum order of ten (!!), but if enough people want SBC6120s we could always go this route. If you're interested, please write to me at bob(a)jfcl.com. Bob Armstrong

Apple II Programmer's Aid ROM

by paulrsm＠buckeye-express.com

Wayne Stewart did a PDF conversion--not just a scan--of the manual for the Apple II Programmers Aid ROM. There are a few typographical errors but it is very good. It is about 278KB. E-mail me if you want a copy. The empty ROM socket in the Apple II at addresses $D800-$DFFF never had an official Apple ROM but there were some third party ROMs such as the Inspector and the Senior PROM. In the Integer BASIC disk file on the DOS 3.3 system masters that area is filled with the Applesoft BASIC code from the same range of addresses. -- Paul R. Santa-Maria Monroe, Michigan USA

The 5155 Challenge...

by SecretaryBird＠SoftHome.net

...At least that it what I called the little challenge I gave myself tonight. I had my IBM 5155 (aka the Portable PC) opened up in order to test some MFM hard drives (a task that failed miserably because the drive controller couldn't handle the ST-251 drives). As often happens, I got sidetracked and started pondering the very limited clearance that most of the slots in the 5155 have, due to the hard drive and floppy drive taking up so much space. I found myself thinking that it would be a shame to waste so many otherwise useful slots; and I subsequently started plotting out what could fit in there. Here is a picture of the (almost) final results... I say almost, because the one full-clearance slot that is still empty has a card slated to go in it, a 3Com EtherLink II. I just have to remember where I put the thing. The last slot is currently being used up by the parallel and joystick connectors that are coming off the IO card in the first slot. I may go ahead and remove those connectors and use that slot for a dual joystick controller card that I have around here somewhere. FWIW, here is what Crysta is now equipped with... Slot 0: - IO Card (RAM, Serial, Parallel, Joystick) Slot 1: - Floppy Controller Slot 2: - Sound Card - Covox SoundMaster II Slot 3: - Reserved for NIC (3Com EtherLink II-TP) Slot 4: - CGA Adapter - DFI 2002 Slot 5: - HDC - WD1002A-WX1 Slot 6: - SCSI - NCS-250-SC Slot 7: - Reserved for Suncom Joystick Card So, anyone else here ever maxed out a 5155 before? Great thing about having SCSI capability is that being limited to a 20MB MFM hard drive is no longer a major concern. If I need more drive space, all I have to do now is hang an external SCSI drive or two or three off the system. Also, while I was working on Crysta, I was thinking that this might actually be a good candidate for the control terminal for the Cromemco System Two; at least until I can get an actual Cromemco Smart Terminal... Anyway, enough random nattering from me for tonight. Time to get the clutter cleared up and go get some sleep. -- Scarletdown

Repairing devices

by pat＠purdueriots.com

I know this is a bit OT, becuase it's not really computer related, but the hardware is at least 23 years old, so that's my excuse for posting to the list... I've got a 35mW HeNe Laser + Power supply that I picked up today for next to nothing. It seems to be having some problems - the laser (somtimes) blinks a few times when I first turn it on, and then stops. From the sound of the power supply it's either a loose connection (which I doubt after opening it up and taking a good look around) or there's a problem with the power supply. Now, I've never really worked on a HV power supply before, and I'm trying to be careful when I play with things. First off, does anyone have a general idea of what sized dummy load ("resisitor") I should try haning off of the HV output to properly load it? I noticed that the laser tube has 3x27kohm resistors in series, would a couple watt approx 81kohm resistor be a good idea? Also, does anyone have an idea for a failure mode to look for? I've got an O'scope, dmm, and various other tools at my disposal, but no 'authentic' HV test/mesurement gear. I'm just looking for general guidelines. Thanks!

TRS80 Model 3 i/o connectors

by acme_ent＠bellsouth.net

Hi -- Having doctored up one faulty drive and replaced the other, my TRS80 Model 3 is now ready for action. It fires right up and will boot several different Model 3 OSes. The documentation I received with the unit contains a lot of detail, but it does not describe all of the i/o connectors on the rear of the unit. The ones which I can identify from the docs are a female DIN connector for tape i/o and a female DB25 for serial i/o. The docs also describe the parallel port as a 34-pin card-edge connector (which I suppose needs a Tandy-specific cable to attach to a printer), but the problem is that there are *two* of these 34-pin connectors on the rear of the system, as well as a 50-pin card-edge connector. Can anyone familiar with this system help me out with details regarding these connectors? TIA -- Glen 0/0 If I am not for myself, who will be for me? And if not now, when? -- Pirkei Avot

MAC's from N.A. > Africa?

I've been asked what is required to make MAC's (Plus, SE, CI, FX) from North America run in Africa. I took a quick looked at a few of mine and didn't notice a switch on the back of the powe supply like some of the older PC's had. Is the costs worth the cost of shipping?

Bringing up a 10 years dormant VAX 11/750

by jwillis＠arielusa.com

Hello all, I just a couple of days ago picked up a VAX 11/750. This machine has been stored in a damp shed for ten years or so, has had mice living in it, and the usual assortment of spiders, etc. After bringing it home, I immediately wrote down what cards were in what slots, etc, before dismantling the system for cleaning. Everything is out of the chassis, with the exception of the console cable and the wires that connect the backplane to the control panel and TU58 tape drive. I'm in the process of cleaning all the components, but am in search of some advice on this process, especially the power supply. How long should I let the power supply dry out from its prior damp condition, and what should I do to bring it up for testing without risking damage to other components? I wish to do this methodically and carefully. Thanks Much! John Willis
