Lear Siegler ADM-5

by dave＠willomail.co.uk

Hi Folks! Another terminal question. I have an ADM-5 here which works fine but when switched off, the display colpases into a very bright vertical line and then to a single point in the center of the screen. This then lasts for about 10 seconds and always happens regardless of the brightness setting. Question is, is this normal and if not, is it likely to damage the phosphor over time? Cheers, Dave

by chuck.mcmanis＠gmail.com

These were the terminal servers of their day. Nice way to hook up to a lot of vintage machines with equally vintage hardware :-) I'd be happy to take these down to the FedEx store and ship them to somewhere. My experience with that before is that its about $30 pretty much anywhere in the lower 48 states of the US. --Chuck

I do singularly cosset the TD-700, having used one briefly, attached to a B6700, however a quite frustrating terminal to use due to the limited line-length of 32 characters - only 8-lines vertically could be tolerated, but the limited line-length on machines that have sequence number fields beyond column 72 meant horizontal scrolling was essential and frequently needed. Still, the SELF-SCAN red display and de-coupled layout (screen+keyboard+control unit all separate) heralded future-times, so it was an iconic object just not practical. I make the count of 4 existent TD-700s, that is pretty good for such an unusual terminal.

Recent Downtime of Bitsavers & Manx

by jwest＠dewey.classiccmp.org

Greetings folks. My sincere apologies for the "unannounced downtime" for manx a few days ago. The downtime was to install a new 33TB NAS, which will allow us to at least double the disk space available to manx (and other classiccmp-hosted sites). You're welcome Richard. Jay West PS - you may see "that is what you get for free", all I see is the $$$ I just spent on a 33TB NAS. Again, you're welcome.

Using an 8" drive on a PC (WAS RE: "Smartcom II" package

by billdeg＠buzz1.com

> A lot will depend on what you want to do. <snip> I was able to make a 8" DOS 6.22 boot disk, but you have to play around with the 77 vs 80 tracks issue when spoofing a 1.2M 5 1/4" drive. Or just ignore the errors at the end of the format, as it will still work enough to get by. I told the computer BIOS I had a 1.2M 5 1/4" drive in A, and used the DBIT adapter to connect to the 8" drive. It may matter what side of the twisted drive cable the adapter is placed, so you'll have to play around with it. I am assuming your drive controller and computer are compatible with the hardware. Format complete, use SYS command from DOS to move boot files to the disk to make it bootable. Once you have the disk formatted it seems to work just fine as a DOS diskette like any other, at least in my disk imaging system. You can walk around and tell people you have a 8" boot drive on your PC, but it's not as exciting to others as you might think.....ug. Anyway I made a thread on my site about my adventures with imaging disks et al http://vintagecomputer.net/browse_thread.cfm?id=561 Bill

Gordon Bell wins S. Cray Award

by jnc＠mercury.lcs.mit.edu

> Gordon Bell, 'Father of the Minicomputer,' Named Recipient of 2014 IEEE > Computer Society Seymour Cray Computer Engineering Award So I was originally going to post that while I whole-heartedly agree that he deserved the award, I was a bit dubious about the 'Father of the Minicomputer' thing, because the only early minicomputer I knew of associated with him was the PDP-11 (which really made minicomputers a Really Big Deal, and is clearly significant); however, the grouping had attained takeoff speed before it appeared. It's a good question which minicomputer was really the first and/or really set the grouping going. Among the claimants would be the PDP-8 (the detailed designer of the original PDP-8 being Edson deCastro), which was surely the first extremely successful minicomputer, and the CDC 160 (designed by Seymour Cray). Another possibility would be the LINC, designed by Wes Clark (whose other big claim to fame was suggesting the ARPANET IMP), and Charles Molnar. Then there's the PDP-5, which was a success, but nowhere near as big a hit as the PDP-8, although it was the inspiration for the PDP-8. I wasn't sure if I class the PDP-5 as a minicomputer, though; it was a bit too big (physically) and expensive. But its architect was.... Gordon Bell! (See Glenn Rifkin, "Ultimate Entrepreneur", pg. 55.) Edson deCastro was apparently the detail designer of this one too. Bell was apparently also the architect of the PDP-8. So it sounds like the title is merited... (And Wikipedia really needs a PDP-5 page. Maybe I'll whip one up...) Noel

Printset or schematic for H7874 PSU?

by robert.jarratt＠ntlworld.com

It seems I have yet another failed PSU (fans turn, CPU gives a diagnostic "F", but DC OK does not come on). This time from a VAX 4000-300 in a BA440 case. I have not been able to find a print set or a schematic. Does anyone have such information? Even just the pinout information for the external connectors so I can connect a test load to see what is coming out? How do DC OK circuits typically work? Regards Rob

Looking for Motorola XDOS for Exorset 110

by chrise＠pobox.com

I am hoping to pickup where Jack Rubin left off with a new to me Motorola Exorset 110 MC6809 development system. This is a periodic query to see if anyone has or may know the whereabouts of an XDOS boot floppy or any other XDOS software for this machine. These would be 5.25" soft-sectored floppies and XDOS 4.0 is the version discussed in the manuals although apparently there was an XDOS 3.0 also. I see MDOS out on bitsavers but those .IMDs appear to be for 8" media and I am not sure how I would convert that filesystem for 5.25" media but it's possible MDOS would boot on this machine also if proper media were available. Any leads? Chris -- Chris Elmquist

Altair 8800 restore details - Model B grounding scheme?

by drlegendre＠gmail.com

Back home now, the trip up north was great.. it got a bit cold, particularly out on the lake, but great never the less! The generally-available 8800 kit manual is for the original (perhaps 'A') version, which contains grounding scheme notes for the 'A' type power supply. My machine has a 'B' type PSU, and as such, may have some differences. Is anyone aware of any differences between the A and B type grounding schemes? Can anyone provide any documentation for the same? Also - I was able to come up with some 1/8" braid to create the several ground straps - but I can't find any 1/4" braid as spec'd in the manual. But again, the manual is for the 'A' series and the 1/4" braid is used on the negative end of the many (8?) electrolytics used on the A type PSU board. I'm not even sure if such a scheme is used on the B type board.. and my board bears no sign that such a scheme were ever implemented. But obviously, the board +must+ be very solidly grounded, so.. how was it done in the day? As ever, thanks for all of your input! The project is coming together nicely..

"Smartcom II" package available

by earl＠baugh.org

From: "Ali" <cctalk at fahimi.net> Subject: RE: "Smartcom II" package available Message-ID: <037e01cfd372$28183000$78489000$@net> Earl, That is pretty cool. Did the NEC system run an 8" based MS-DOS? Or was it a different variety of DOS (or straight CP/M)? I have heard rumors of MS-DOS natively available on 8" disks but I have never seen one. If it is MS-DOS how compatible is it with MS-DOS versions of the same vintage? Thanks. It seems to be a pretty "standard" MS-DOS from Microsoft. I don't have the original disks, so I can't say for 100% sure that it came on 8" but I wouldn't think it would work properly if it hadn't come that way. It "seems" to be pretty darn near the same MS-DOS that I remember. I've not, however, got my setup in place yet to get info from a 5.25 to an 8 so I can test out other programs on it to see where it has issues. I saw a great presentation from Malcom during VCF East 9.1, and have slowly started trying to pick up the pieces that he listed for his disk imaging system. I'll be sure to report here when I have that done and can get some SW onto more disks... (if anybody wants to send me a disk with something they'd like to know if it works, I'll more than willing to give it a go... and send the disk back when done...) Earl p.s. I need to find a sturdy table to put it on... it's on the floor right now... because of that old maxim : You can't fall off the floor. :-)

Need name for Velcro-like connecting mechanism

by jnc＠mercury.lcs.mit.edu

I have a Sigma BA11N LSI-11 box which is missing a front panel; I need to build a replacement so that the airflow works properly. Building the panel isn't a problem - what is, is getting the device that keeps it on, which I need to source - only I don't know the name. It's a plastic thing that's sort of like Velcro, but it consists of numerous small stalks (about 1mm high, and slightly less than that in diameter), with little spheres (slightly more than 1mm in diameter) on the ends of the stalks. If I knew the trade name, I'm sure I could buy some - but I don't know what it's called. Anyone out there know? Thanks! (Of course, if anyone has a spare Sigma front panel, that would be even better, but the odds of that... :-) Noel

OT: Need Weller soldering pencil / iron for WTCP station (TC-201)

by drlegendre＠gmail.com

A younger fellow, new friend of mine, is trying to get into the electronics hobby - and he needs a decent tempco soldering outfit. I gifted him with a Weller WTCP type base - the older style, with the iron holder built in to the top of the base. But I didn't have a spare TC-201 type pencil, or "irons" you might say, to work with the base. If anyone has a spare, working pencil for this base, please email me off-list. Send details and asking price.. and if you have a spare tip or two, etc, go ahead and let me know. He's short on funds and I'd like to help him get-going with a decent set. And while I'm never one to "blame the tool", the main bench iron is no place to skimp.. cheap irons +can+ make good joints when needed, but not in the hands of a novice - in my experience. I don't want to hobble him with one of those $5.99 Willy Wong specials.

Crating / Shipping assistance (near Toronto)

by derschjo＠gmail.com

Hi all -- About a year back I made a deal to acquire a pair of workstations located near Toronto, ON with the plans to drop by at some point to pick them up (my family lives in Michigan, so a road trip was expected at some point...). Unfortunately, these plans have all fizzled out and I really don't want to leave the guy who is very kindly holding onto these waiting for too much longer. He's not excited about dealing with crating / shipping these himself (hence the road trip plans, etc.) Is there anyone in the area who might be willing to help me out in the somewhat near future, to pick the machines up and drop them off at a nearby shipper so I can get them back to Seattle? (Any shipper recommendations in the Toronto area? Looking for someone who can do a decent job crating these up...) This is a pair of Xerox 6085s, including monitor, keyboard and some software. It should fit into the back of an SUV, or be crammed into a sedan if you're clever about it. Drop me a line offlist if you're willing to help me out. Thanks, Josh

It's BASIC Week on RetroBattlestations

by fozztexx＠fozztexx.com

It's time for another type-in BASIC program challenge! Are you ready for BASIC Week 3: Under the Sea? This time around instead of just being a picture or an animation, it's a game! You take control of a sea turtle in a sort of endless runner type game. The turtle constantly swims from left to right and the A & Z keys move the turtle up & down. You need to eat food (x/y characters in most versions) for points. Running into enemies will cost you air. You can refill your air by catching air bubbles, or you can surface to refill completely. When you run out of air it's game over and the turtle goes belly up. All you need is a vintage computer that can run BASIC. Like all the BASIC Weeks before, if you've got a computer with BASIC in ROM you'll only need a working computer and monitor. There's no requirement that you save the program to tape or disk, just type it in and run it. Come check it out: http://redd.it/2fn1zq -- Follow me on twitter: @FozzTexx Check out my blog: http://insentricity.com

WTB: Unix/Solaris Adobe FrameMaker 8

by other＠oryx.cc

I am looking to purchase/acquire a copy of Adobe FrameMaker 8 for Unix/Solaris. Straight from Adobe, FrameMaker had always been a pretty pricy item, but I had always managed to acquire a legal copy, sometimes years old and after the fact through eBay, etc. And through that method, I own legal copies+media of 5.x, 6.x and 7.x for Unix and Mac. I had hoped to purchase a copy of version 8 via a similar method, but several years have passed by, and I have never seen a copy of version 8 for sale. After version 8, FrameMaker was significantly changed and released for dos/windows only. I believe that the current version is 11.x. Also, in case it isn't obvious, this is for myself for home use only. Jerry

Altair 8800 restore details - Model B PSU & case details

by drlegendre＠gmail.com

Trying to suss-out the details of 8800B PSU layout and case assembly. So far I've only come across one user-created image of an Altair 8800B PSU, see link below. I'm looking for additional images, from different angles - and in particular, a couple pics of the 8800B case from the _rear_ so I can get an idea of what kind of perforated metal was used to cover the fan cut-out. The linked pic shows something back there, but it looks way too restrictive of airflow and I don't think it's original. IIRC, there is one image out there that shows a round-hole perforated metal in that location, as well as covering the connector slots - but I've been unable to locate it. As ever, any MITS official documentation on the 8800B assembly process, PSU in particular, and any associated engineering drawings would be much appreciated. The A model is well-documented, but I can't find scratch on the B version, which is substantially different in several areas. The B models _were_ sold as kits, weren't they? If so, then there is or at least was a manual..

by jnc＠mercury.lcs.mit.edu

> From: Paul Koning > That said, B+ was an excellent implementation of a 1970s era BASIC. Indeed. RSTS and BASIC were the first computer I actually used (back in '72 - an 11/20 with 48KB of memory, an RF11 disk, and about 6 ASR33's :-), and I have fond memories of it. I learned how to program by reading the RSTS BASIC language reference manual over a weekend! Noel

Just remember -- regardless of which BASIC you're talking about. . . . Basic-Plus under RSTS/E transcends them all. . . . ;-)

Agreed...I've done this with Asterisk, and it works pretty well. Couple of things: 1) Make sure you get an IOS version that has the features you need (VoIP). Even the mc3810 has versions that don't do SIP, among other deficiencies. While there are numerous ways to "obtain" IOS, it's not free. 2) If you go mc3810, try and get a V3 model. Latest IOS for it is 12.3.3, but that's marked LD (limited deployment), so it might be better to shoot for 12.2.26c, which is the latest GD (general deployment) 12.2 chain. 12.3 might be fine, but I've never used it. 3) I think the latest IOS for c2600/c3600 (non-XM models) is 12.4.25. Any late 12.2, 12.3 or 12.4 release should work OK. 4) Cisco 1700s are also an option, as are a bunch of other models that you can stick an analog NM in. KJ

Several hundred pages though; might take me a while to scan them. Nag me off-list. Your namesake Nigel Williams down under may also have some relevant info. @ Richard: Not sure if I still have any brochures with pictures; will let you know if I find any. mike

Hello all, in out previous big haul there is a Apollo DN560 computer, with huge monitor, mouse and keyboard. unfortunately it is missing its video cable. computer side is a 13w3, splitting in (i think) a db9 and three bnc's. is this a straight through cable or is the db9 mapped out differently? I would love to boot the machine. -- Met vriendelijke Groet, Simon Claessen drukknop.nl

VCFMW9 Post-Show

by silent700＠gmail.com

Hello ccmp'ers - I have compiled photo galleries, videos, presentations and other media from VCF Midwest 9.0 on our web page here: http://vcfmw.org/past.html If anyone attended has anything I missed that should be linked there, please post it in this thread and I'll put it up. It was a great show this year, with record [1] attendance and some really impressive displays. We can count Texas, New Jersey, Pennsylvania, Toronto, Portland OR amongst the places people travelled >from to see our little Party in the Basement. As happens every year, I am seeing things in the pics that I didn't even know were there, under my nose. Big thanks to all who showed, sold, spoke or just attended - it would be just another handful of nerds in a hotel without you. Until next year... - jht [1] Based on not much more than shirt sales, missing badges and the general buzz about the place.

Digiac 5502 and 5503 Exercisers

by radiotest＠plymouthcolony.net

A couple of interesting items followed me home recently - a Digiac Model 5502 Monochrome Monitor Exerciser and a Digiac Model 5503 Dot Matrix Printer Exerciser. The 5502 seems complete. The 5503 is missing the (presumed) DB-25 and Centronics cables, but I can replace those using old printer cables on hand. In addition to the models that I own I have also seen references online to a Model 5501 Power Supply Test Load Unit and a Model 5504 Floppy Disk Drive Exerciser. I have no manuals - does anyone on the list have scans of any of the manuals for the Digiac 55nn series that they would care to share? Dale H.

Sun Microsystems Model/Price Lists? (and Sun 1 research)

by earl＠baugh.org

Thanks Jerry, I'm on sunrescue at sunhelp and dug around there because of that. It was a good source which lead me to send an updated 3Com doc that I had to bhtooefr at gmail.com I didn't hear back, and the dates of these are 2010, so not sure if he's keeping things updated... Do appreciate you forwarding the info... you never know who knows what, etc. And this wasn't something that I found on sunhelp initially...

Sun Microsystems Model/Price Lists? (and Sun 1 research)

by earl＠baugh.org

Howdy, As part of my Sun 1 research I'm trying to identify some of the model numbers that existed for Sun 1's. I've got the original Sun description doc that has most of the "initial" sun 1 part numbers. However, I'm missing some info from between this initial list in 1982 and the 1988 price list which has the Sun 3 items. So later Sun 1 info, and all of the Sun 2 price/model info I don't have. Anybody seen any docs from this period? Al, is this perhaps on your queue to scan? Also, just FYI, as of right now I have hard evidence of 13 machines (11 Sun 1/100 or 100U models, 2 Sun 1/150U models) with some fairly strong but tentative info on 5 others (4 100's, 1 150) And as of right now, I only know of 1 that definitely boots (and 2 that did "recently", but haven't been tested again...) Earl (BTW, the first post of my rescue story got posted to my http://www.vintagecomputerexpo.com blog)
