The only difference is that I know of was that the threshold for data was a slightly different voltage. The 8702A was designed to tie directly to a 8080 or 8085 without additional buffering. Otherwise, the 1702A spec will work. If y9ou want the exact levels, I can look it up. Most current programmers do not support the 1702A's. You'll need to find an old programmer someplace. Dwight

Request for help with a PDP 11/73

UPS has already come by and they agreed to process a claim. My options are to get my money back and give them the machine or to get it fixed and they pay for the repairs or replacement -- up to my costs. I don't think replacement is very possible. The UPS guy suggested that I go to circuit city or Best Buy and buy the replacement parts.... Uhhhhh.....

Compact Flash (CF) cards

by Robert_Feldman＠jdedwards.com

You may have run out of interrupts for the CF card -- it requires two, one for the drive interface and one for the card, IIRC. On a laptop I had at work, I had to disable the modem (which I seldom used) in order to free up a second interrupt so I could read PCMCIA flash RAM cards that I used in my HP 95LX palmtop. -----Original Message----- From: gil smith [mailto:gil@vauxelectronics.com] Sent: Tuesday, February 04, 2003 4:28 PM To: cctalk(a)classiccmp.org Subject: OT: Compact Flash (CF) cards <snip> I got a couple of Compact Flash (CF) cards to play with, and I also got a CF-PCMCIA adapter to try the cards in my laptop.

New to list

by ssj152＠charter.net

Hi, I am new here; I've been lurking (reading the archives) for a while, decided to join. Since I retired I've taken up "retrocomputing" and see a lot of discussion here about systems I'm interested in and hopefully I'll be able to contribute at times. I am certainly having fun reading the posts - the recent posts about "middle posting" really cracked me up! I am interested in 6502 based systems, especially the KIM-1 and SYM-1. I currently have a VIM-1 and a SYM-1, having years ago been thickheaded enough to sell my KIM-1. Wish I had one now, can't afford one on eBay. I have nothing against the AIM-65, I just have never fooled with one and haven't been able to pick one up yet. My interest in small 6502's has been extended to small "trainers" with different CPU's, like the Heathkit ET-3400 and the HP 5036A. One of these days I may get around to fooling around with PIC's, but I'm still having too much fun with the old stuff. I'm looking for a copy of the HP book "Practical Microprocessors, HP part number 05036-90003" if anyone has an affordable source for one. I have inquiries out to several "manual" sites and am awaiting replies. I also have history with PDP-11's, using RT-11 and RSX-11M. I have a PDT-11/150 at the present and run RT-11 on it. What I'd really like to have is a H-11 (yeah, I can really afford that...no way) or better yet, a DCT-11 trainer. I saw 3 of the DCT-11's go by this fall on eBay and wasn't in a position to bid. In recent years I worked with VAXes and have several VAXStations and MicroVAXes, in the 3100 and 4000 series. I'm not sure these qualify as classic (3100-10e, 4000-VLC, 4000-60, 4000-90). I also have a few Alpha's. - Multia, AlphaStation 200 4/100, and AlphaServer 1000A. I spent the last 10 years of my career as a systems programmer working with OpenVMS in a process control (SCADA) environment. I am not so much a collector as a user and builder of computers and peripherals. By that I mean I'm not trying to corner the market, open a museum, or that I consider these computers as "investments". I am not likely to sell anything, but might be interested in buying a few things, especially documentation for some of the machines I have. What documentation I have I may at some time convert to PDF and publish for anyone else interested to play with. Stuart Johnson ssj152 AT charter DOT net

OT: Compact Flash (CF) cards

by gil＠vauxelectronics.com

Hi folks: This is off-topic, (and if you are in the sbc6120 group you have already seen it): I got a couple of Compact Flash (CF) cards to play with, and I also got a CF-PCMCIA adapter to try the cards in my laptop. Unfortunately, I cannot get Win-frickin-98 to see the card. I have a similar Smartmedia-PCMCIA adapter for camera cards, and it seems to work fine in the same machine (ibm thinkpad 600e). In both cases, I inserted the card/adapter, WinBlows sees it and starts the device wizard to install a "Standard IDE/ESDI Hard Disk Controller." For the Smartmedia card/adapter, the card automatically appears as a drive in Explorer, and all is well. For the CF card/adapter, it asked me to reboot, and even then does not see the card. The Device Manager Status for the controller says "device not present, not working properly, or does not have all drivers installed (code 10)." There are no resource conflicts to correct. However, the controller driver is seen by the PCMCIA utility that allows me to stop the card for removal. I've searched at ibm and microsoft, and various google finds, but cannot make sense of this, and have already spent way too much time on it. Has anyone had problems or success reading CF cards in Win98 with a PCMCIA adapter? Is a usb adapter a better choice? Upgrading the o/s is not an option, since I never intend to give microsoft another penny. thanks in advance, gil ;----------------------------------------------------------- ; vaux electronics, inc. 480-354-5556 ; http://www.vauxelectronics.com (fax: 480-354-5558) ;-----------------------------------------------------------

PeeCee obtained 5000AT

by jwest＠classiccmp.org

Recently obtained a *BLUSH* old PC. Normally wouldn't post about it here but... someone may be interested in a copy of the software on it. This thing is kind of a slimline desktop case, has a 3.5 floppy and 5.25 floppy. It's a leading edge model 5000AT. I think it is a 286. But what might be interesting to some is, it comes with something called "windos" I believe, and is a leading edge specific "make the computer simple" GUI sort of. Basically just lets you point and click to call 123, easywriter, etc. I thought someone might be interested in the software & gui files. God I feel dirty now *G*

Is there such a thing as a ZIF socket for PLCC chips?

I am needing to burn PLCC-packaged chips in my DIP programmer. I expect I need to locate a PLCC<->DIP adapter of the right size (for 29C010 and 28F101 Flash chips, at the moment). Thinking about it made me wonder if any of the sockets were ZIF or LIF. Any ideas? Any recommendation on a source for adapters? Thanks, -ethan

[OT] Anyone experienced with white LEDs?

by zmerch＠30below.com

I'm looking at building a personal lighting project possibly using white LEDs instead of regular miniature bulbs, and as I browsed the Mouser catalog, I got a whole lot more confused than less... I'm trying to get the maximum amount of light for current expended, and the numbers seem to be nonstandard, or at least not enough info is provided... :-/ Example: P. 217, "Super Flux LED Lamps" The white one shows at 20mA it will put out 400-600 "Iv (mcd)" P. 216, "Blue & White LED Lamps" The brightest white they have is listed as: "2200->3200 "Luminous Intensity" but with no mention of current or value (mcd? ucd? ) P. 199, "Thru-Hole White LED Lamps" "Luminous Intensity" ? current would output 1.7->2.3->2.6 (min/typical/max) mcd... and on P. 206, there's a few colored LEDs output listed as "Foot Lamberts"... And Digi-Key has these Surface Mount Incandescent Lamps... :-O The look cool, but how hot do they get? (It's a very small installation area... It's still an idea I'm forming, but if it works out, it's a *kewl* idea...) Any good websites w/info on how to figure out how many LEDs I'd need to make about a 40W (or more) lightbulb worth of light? -- Also, my college electronics braincells are rather weak, as I can't remember if the wattage rating means "total dissapated wattage" or "total wattage of the circuit branch it's in"... [1] ... I'm getting too old for this ... Any help/pointers would be *massively cool*... Thanks! "Merch" [1] - I want to use SMT current limiting resistors [2] (fewer holes to drill...) and the highest wattage ratings I can find is 1/8W... in a 6V 20mA circuit it's running real close... (I could run ~17mA to get a margin of error... but I want the max light I can get...) RatShaq has 1.2A 6V wall-warts for a reasonable $, and I wanna build a "different" light fixture. Of course, I want a *usable* light fixture... ;-) [2] - I wish I could find SMT white LEDs... :-/ -- Roger "Merch" Merchberger -- sysadmin, Iceberg Computers zmerch(a)30below.com What do you do when Life gives you lemons, and you don't *like* lemonade?????????????

summary: DEC VAX/VXT2000 and monitors

by Fred.van.Kempen＠microwalt.nl

All, Thanks all for the info. Basically, there's a whole myriad of cards and monitors for DEC systems, and there's no single tube that works with them all. Solution (for me, ymmv) was to get a (cheap! :) multisync monitor with BNC connectors and sync-on-green capability - I was able to get a used Iiyama MF8117T (known to US people as IDEK MF8117T) 17" tube. Works like a charm, rock-solid picture on all systems I could set up for testing. Neat! I am typing this in a window on that thing, connected to the VXT2000+ X Terminal, which in turn is connected to my OpenBSD VAX (4100). Yay! --fred

He said that you could type in a letter and insert a pause any place where you wanted to insert unique data such as a name. The unit would save everything on punched paper tape. You could then feed the PT back into and it would type the letter. When it got to the pause it would stop and let you manually type in the name or other data and then it would continue and finish the letter. Does anyone know what these thing was? I think he must have gotten this after I left home because I don't remember ever seeing it. Unfortunately he threw it away several years ago. Joe

This is not so easy to figure. You need to know how efficient the LED's are, relative to standard bulbs. It seems like I saw something that said that LEDs were not quite as efficient as fluorescent lamps but still better than incandescents. If we figured them at twice as efficient, you'd need 20W's of LEDs. Watts is just the current times the voltage. You figure this for each LED and add them all together. LEDs do require a circuit to limit the current. When you figure your total light output, you don't count the loss in the control circuit. Of course, for the final tally, you'll need to include this as well. When driving a number of LED's, it is better to drive a large number in series because you only need one current limiting circuit. The count of LED's would depend on the voltage source you have available. You'd have the total LED voltage plus the drop needed across your current limiting cicuit.

Well, Intergraph still makes computers, they're just PCs.. But you guys missed Concurrent, the descendant of Interdata and Perkin-Elmer, who specializes in Video On Demand solutions.. they also bought Harris's computer division, for the nighthawk.

If your mail software doesn't do what you need it to do, maybe you need to complain to whoever sells and supports it, or find other mail software that does do what you need done. Asking the rest of the net to change so that you can keep using losing software is not nice. > I still vote for a small [cc] tag. In front of the subject. Here's how that works out here: I set up my mail software to strip the tag so I don't have to see it. (Clearly, my mail software wins: it doesn't just do what I need, but also what I want.) Then, when I reply to the list, my reply's subject does not have the tag. So messages in the thread can have at least three different subjects: [cc] foo Re: [cc] foo [cc] Re: foo I'd bet that there's a fourth possibility based on phase of the moon: [cc] Re: [cc] foo Do you begin to understand why I think subject tags are not a good idea? > > Just accept it already and SHUT UP! > No. Yep, that's the problem. The way your message came across out here in Sillycon Valley was: "I know we've been over this before, so there's no need to discuss it, just vote to do this and then us folks who cling to our losing software will stop bringing it up." This is not the way to win friends and influence people, not that there's much hope of influencing me on this point. -Frank McConnell, filtering his incoming e-mail since 1994

I am on some lists that do this, and long discussions (like this list is notorious for) end up quickly becoming nothing more than a subject line of "Re: [cc]" repeated over and over. And no, a smart list server that can handle tags (and thus not insert them on messages that already have them, or insert them after the Re:) doesn't always help. Some mail clients/services munge them. And all it takes is one person in the discussion with an effected client, and the whole thing gets thrown out of whack. -chris <http://www.mythtech.net>

I'd like to agree with Eric, and also to remind people that this has been tried on the CLASSICCMP mailing lists, and it annoyed the H*** out of so many of us that it was stopped.

Ultrix V4.20 sources and binaries

by msokolov＠ivan.Harhan.ORG

Hi everyone, A number of people have complained to me about not being able to unpack the tarball with Ultrix V4.20 sources that has been on my FTP site since May 2001. I have finally found the time to look into the problem and indeed the file was corrupt. Fortunately, I was able to read my old backup tapes (from Cleveland, OH, 1999-07-15) without any problems, and discovered to my great joy that this file was good on my Cleveland machine. (It apparently got corrupted in one of the turbulent moves from Cleveland to Dallas, TX and then to Orange County, CA. I don't have any idea how.) ivan.Harhan.ORG:/pub/UNIX/thirdparty/Ultrix-32/sources now contains *good* Ultrix V2.00 and V4.20 sources. (Be warned, though, that this machine resides in my cave which is connected to the outside world through a modem which usually connects at 31200 BPS, sometimes 28800. Feel free to set up a mirror.) For what it's worth, I have also put up my Ultrix V4.20 distribution tape images in /pub/UNIX/thirdparty/Ultrix-32/ult420vaxdist-tk50. They are quite incomplete, however, as when I had the tape in my hand (at CWRU in spring 1998) I was unable to read it entirely without errors. Therefore, the V4.00 tape images in /pub/UNIX/thirdparty/Ultrix-32/ult400vaxdist-tk50 will probably be more useful for most people. If you have the guts, install V4.00 and then recompile V4.20 from the sources! -- Michael Sokolov Programletarian Freedom Fighter International Free Computing Task Force Let the Source be with you Programletarians of the world, unite!

Pro_Log STD BUS manuals needed

by RCini＠congressfinancial.com

Hello, all: I bought a STDBUS instrumentation computer off of eBay last week for $9, and it has some interesting boards in it. Unfortunately, the boards are mostly older Pro-Log models and information is sparse. I've made contact with the "legacy" manufacturer who wants $50 per manual for two of the boards. I found information for two of them on VersaLogic's Web site. So, here's the list of boards. If any one has original Pro-Log manuals for these that they can copy and send me, please contact me off-list. Pro-Log# Description 7303 DSKY (Display/keyboard module) 7502 Relay output module (8 relays) 7605 Programmable I/O 7806-1 Z80 CPU card (I have copy of VersaLogic's manual) Other P-L boards from another system I have: Pro-Log# Description 7805-1 8085 CPU card 7604A 64-bit digital I/O (I have copy of VersaLogic's manual) Thanks again for any help.

DEC7000 Rackmount docs?

Dolch Logic Instruments 8086 Trace Module....

I got this thing (Dolch Logic Instruments 8086 Trace Module) along with a bunch of other stuff at auction. If it is of any use to anybody, let me know right away. Otherwise it will soon get scrapped or trashed or binned or skipped, and it looks too nice a piece of work for that. Best regards, Dan McDonald Bellows Falls, Vermont USA

OK, what happened to the things that made Burroughs Burroughs? I worked there from 1986 to 1989. The B1000 machines were EOL'ed when I got there and I pretty much had the B1965 at Lake Forest (Orange Co., CA) to myself doing support for HOSTLINK and GEMCOS. I think Art Sorkin (Mr. B1000 MCP) had one in Mission Viejo doing MCP support. I never cared much for the Pasadena machines (the V-Series or Medium systems) and I don't know when they were EOL'ed. There was a lot of B5000/Large System/A-Series hardware development after I left, but I don't know what happened to those machines. Is anyone still commercially running any of this hardware? I am not sure which CT machines you are talking about or if you have the full story on CT. When I joined Burroughs, they were selling a line of desktop computer called B20 (even though there were B3x machines). These machines were made by CT and ran an OS called BTOS (a variant on CT's own CTOS). They were kinda cool because the form factor for each component was something like a 10" tall by 10" deep by 4" wide box (called a 'slice') and you added slices together (say, a CPU slice, a display slice and a disk slice) to make a working computer. alan
