OT: exchange of DNS secondary service?

by tomj＠wps.com

I do realize this is largely off-topic (though it's on my net machine that supports vintage computing activities), but I cannot think of a better bunch of people to ask. Please reply off-list. I have a long-lived, well-placed and reliable machine on the net, turing.wps.com, and I'm looking to exchange secondary DNS service with someone outside the U.S. or on the East Coast. My server is in a secure, A/B powered telecomm colo in Seattle Washington, 600+ Mb/s to three ASNs. I have a lot of heavy DNS experience so when I foul up I do a really good job of it. I've got a half-dozen zones, all small, and would set up axfr's for you in exchange for me. This of course does not require me to have access to your machines, and vice-versa, we just set up bind config. Swap for like service, no money involved.

New finds: Some days you win, other days you WIN!

by rigdonj＠cfl.rr.com

I got a call yesterday from one of my steady sources. He finally got in the load of Intel Multibus manuals that I'd been waiting for. Went down there this morning and spend about 4 hours digging thru a pallet load of manuals. Found about 50 Multibus manuals. But only three different manuals. Yeah. About 15 copies of each one! While I was there, they were sorting out another load of OLD stuff that they'd just gotten. There was a lot of '40s, 50s and '60s electronics in it as well as a lot of typrewriters, checkwriters and mechanical adders. while I was there I went over and looked in the scrap basket where they were tossing out stuff and in the bottom I spotted something that said "Flexowriter". I really didn't want to have to pull out all the junk that had been thrown in on top of it but decided to find out more first. A quick call to Alex Knight (aren't cell phones great?) and he confirmed that I SHOULD dig it out. So into the basket I went. An hour later and I was the proud owner of not one but TWO Frieden Flexowriters! Anyone have a manual or more information about these? Also found some OLD modules that are marked Digital Logic Modules. They're made of black plastic and about 1 1/8 square and 1/4" thick and have ten pins on the bottom. The pins aren't round but are blade shaped like those used on Jones plugs. There's no name on them but they have a symbol of a capital R with the electrical symbol for a resistor superimposed on it. I think I remember seeing that symbol a long time ago but I can't remember who used it. Does anyone remember it. Joe

1mbit dram chips?

I used to have one like that, and I may even still have some SIPPs -- but they would be 256K SIPPs, which you probably don't want. However, you do realise that SIPPs and SIMMs of the same size (capacity) have exactly the same pinout? You could either tack pins onto SIMMs (I've seen it done) or fit a SIMM socket to the board, if the spacing between the SIPPs is standard. I may also have some 1MB DRAM.

"Old PC" emulation ?

by waltje＠pdp11.nl

Hi, While reading up on my old Minix stuff (I found a box full of my old Minix backup floppies a couple of weeks ago), I tried to install them onto a PC I, um, borrowed from my customer (I was in Oslo for the week, and was bored at nights ;-) but that would not install. Obviously, old system software does not necessarily have to run on the new, current (PC) systems. Which led me to consider the impact of this on being able to run the older PC software anytime in the future. Can one still install a QNX box, or a Minix box, or an OS/2 system? So.. what it boils down to is: is there any (serious) project on doing a "old pc systems" emulation a la SimH, which does, for example, a pure IBM PC, PC/XT or PC/AT ? Just some random thoughts...

Up For Grabs: HP 13037 and HP 7925 disk drive

by rigdonj＠cfl.rr.com

I spotted these in a scrap place today. I brought the 13037 home but the 7925 was too big to fit in the car. The 13037 looks like it's in perfect condition and I have the cables for it. I think this stuff orginally came with the HP 1000 that I found last week. At any rate, I have 13037 interface cards in the 1000 and I'm willing to part with them too. The 7925 appears to be complete and in good condition. However it was dropped off of a truck and may be damaged internally. I don't know if the heads and spindle were locked or not. I have no way to haul or ship the 7925 so don't ask. It's located in central Florida so plan on coming and getting it if you want it. Anyone intersted in the 7925 needs to let me know ASAP so that I can make sure that it doesn't get torn apart for the gold scrap and aluminium. Best offer or trade me something that I can't live without :-) Joe PS it looks like these have the MAC interface.

facit n4000 service manual?

by jwest＠classiccmp.org

My facit N4000 reader/punch has developed a problem. Would anyone have a service manual for this unit? I have the operators guide but no service manual. When powering up the unit, about 20% of the time it comes on with "Err" in the display. If I turn it on and off a few times, it comes up correctly with "Off" in the display. Also, the test tape created in diag test #4 mostly, but not always, passes it's read in diag test#5. Can anyone help with a loan of the service manual or perhaps some advice? Regards, Jay West

Ok, I am replacing the HP terminal with either a Macintosh SE or an Apple IIc+... Environment = Linux running simh pdp11 running RSTS/E V7.0 (with telnet from all my other machines) Has to sit in a 2" x 2" square area on my desk, although I think all three choices overflow the intended area. Please weigh in on the following three scenarios: Door #1 - Macintosh SE - Have an appletalk laser printer for this machine - perhaps smaller footprint. Door #2 - AppleIIc+ - Imagewriter instead of a laser printer if any printer at all. - Coolness factor (8 on a scale of 1 to 10) 10 would be a real DEC terminal.. - No Terminal software at hand.. (would beg someone to send me a diskette) Door #3 - HP Terminal - already and still hooked up, and works ok... but. - it's not *also* a computer that I want to get back on display. Your comments requested.

new find: another HP 1000!

by rigdonj＠cfl.rr.com

I finally checked out the HP 1000. It seems to work. I checked and the CPU section has a DCPC card, Memory Protect Bd, Mem Bd, four 256KW memory cards and a 2102E Memory Controller. The IO side is full of cards. Here's the list: I/O Buffer, I/O Buffer, 12966A BACI Bd, 13183 7970 Mag Tape 2, 13183 7970 Mag Tape 1, 26099A Line Printer, 26099A Line Printer, Bus I/O, 12966A BACI Bd, 12966A BACI Bd, 13037 Intface, 12821A Disk Intface, Time Base Gen, FEM. It seems to be quite a nice machine. Joe I went to one of my favorite scrap sources today but I was just there a few days ago so I didn't expect to find anything. But I was wrong! I found a NICE F series HP 1000 along with the Floating Point Unit. I haven't looked at it closely yet but all the card slots are full and it's in very good condition. It was mounted in a short (desk height) HP cabinet marked "HP 1000 System" along the top. Unfortunately I had to leave the cabinet, it was just too big and heavy fit in the vehicle that I was in. I'll go through the computer later and give a full list of all the stuff in it. Joe

>In the meantime, I've used my portable Cybiko as an eBook reader, and a few >other trivial tasks. I know this is going off topic, but how well does it work as an eBook reader? I'm looking for something fairly portable for ebooks. I have stacks of books and manuals in either HTML, Text, CHM (crappy HTML), or PDF format. And I haven't read them all yet because currently my computer is the best place to read them, which conflicts with me getting most of my reading done on the crapper. So I either need some portable unit to start reading ebooks, or I have to install a computer in my bathroom... humm... no for the sake of my marriage, I'd better just go with a portable unit. I've used my Palm for the text files, but the formatted HTML, and CHM files don't work so well on that small of a screen. And my Palm can't handle PDF. Is the Cybiko any better of a screen then a Palm? Can it do anything beyond plain text? -chris <http://www.mythtech.net>

URGENT - Big IBM Iron rescue - System/38, Ohio

by mross666＠hotmail.com

(CC'd to a couple of System/38-seekers I know of...) Hope someone can jump on this... a guy has to dispose of a complete System/38 setup, believed working - by the weekend. Miamisburg, Ohio. The unit has to be cleared by Monday of next week. He wants an arrangement in place by Wednesday, but the actual removal can wait as late as the weekend - so long as the collector is 'damn sure' he WILL turn up as promised! He tried the stuff on ebay at too-high prices, got no bidders - but at least you can see the pics (System, disk, tape, printer): http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=5134099178 http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=5134099696 http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=5134100141 http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=5134100797 Someone needs to move *fast* on this - contact the guy immediately. If no-one steps up to the plate, at minimum I'll try to get him to remove the boards from the /38, so I have a spare set for mine. Contact is Mitch - email miller(a)keyways.com or call him - 937-902-8392 I'd appreciate it if anyone is seriously interested, let me know too. The guy will want some money; he has an offer for the whole lot from a scrapyard, and they'll take it away if we don't. Good luck. Mike http://www.corestore.org

classiccmp hardware

by jwest＠classiccmp.org

All the hardware is finally in for the mirroring setup. I was going to go with software raid till I found out that the system won't boot when the primary drive fails (ie it won't automatically boot from the 2nd drive). So I went the hardware raid direction. The new hardware includes a 3ware Escalade 7006-2 controller ($123.70), and two 160gb PATA 7200rpm 8mb cache drives ($88.54 and $67.22, respectively). Total hardware expenditure including sales tax and shipping was $279.46. Of course, I'll take the time to reinstall from scratch rather than just copy the existing drive. So we'll be getting newer versions of freebsd, sendmail, mailman, mysql, php, etc. etc. etc. My intent is to throw the drives into a small test system and put that at the datacenter and configure/install everything remotely. Then when it's time to switchover, I should be able to just move the drives (and controller) from one system to the other and come back up. Then I'll start the process of migrating historical data from one to the other (by putting the old drive into the test machine). I'll give the list a big heads up when I get around to scheduling this. After this upgrade is done, I will be looking for volunteers (web design people) to see about giving the classiccmp site a facelift, possibly adding some new features, and (finally) cleaning up the archives.

Heath EC-1 on eBay

by dwight.elvey＠amd.com

Hi John Now there are two on ebay. The latest one is a little more on the conservative side. Starting at $990 with a buy it now price of $1250. I don't recall ever seeing one of these go for more than about $600. The first one does come with the plastic component holders. I wish I could find these today. They were actually half of the 300 ohm TV twin lead connectors. RS used to have them but has stopped carrying them. I've found that the miniature banana connectors from Pomona also work but they are expensive. I like the comment that one can not use the EC-1 without the operation manual, that the second fellow states. That is like saying that a person can't use a car without the operators manual. I guess that is an indication of the state of knowledge now days.

Intel MDS Further Information

by dwight.elvey＠amd.com

Hi Scott This is a Series II machine, not a Series I ( no such thing as a Series I ). The IPC card is the indicator. That was only used in the Series II's and Series III machines. The Chassis should also have a non-multibus card called the IOC card that runs the terminal and the SD controller. The IPC card is the main processor card. It is the one that runs any code that you'd normally run from the disk. Also, you should note that there is an small interconnect for the aux bus connector that goes between the two disk controller cards. This may be bolted to the frame but it need to be there for the cards to work. Dwight >From: "Scott Stevens" <chenmel(a)earthlink.net> > >This weekend I had the time to pull open the Intel MDS system I >mentioned last week, and record info and photograph all the Multibus >cards.

I jumped to soon, I checked into the two board set and Dwight is indeed correct about the channel board only being test signals.

new find: an Intel MDS 800

by dwight.elvey＠amd.com

Hi I knew one of the fellows that wrote the 3000 code for the double density controller. A fellow named Lou Bolardo. It always astounded me that it took 2 boards to do a disk controller.

Hi The controller boards for DD were not that hard to talk too. The fact that they used the 3000 series had little effect on the main bus interface.

it works just fine and I just cut and pasted it from browsing just before I sent the message. I also just cut and pasted the link just a moment ago that I gave out and it works fine. Try going just to www.Intel.com - if you can't get there it could be a Florida issue (I am in Virginia). Every once in awhile, the lines appear to go down that connect the US together. If the browser said it was trying to open the site then the DNS server supplied an IP address to your browser and there is a line issue to the west coast. If it said it was trying to find the site, then you were not able to get to the DNS server to translate the name to an IP address and your connection to the DNS server is in question. Of course it could be a browser issue if you aren't using that OS and browser that lots of people seem to blast all the time...

cp/m box for software

by emu＠ecubics.com

Hi all, did a little work on cp/m in the good old days, and thinking about getting at least one machine up again. As it would be mostly for having fun with the z80 again (or 8085, z180, z280?), I'm probably not interested too much in having any of the collector grade machines. So, the question is, what is the best cp/m machine for playing with the software ? cheers & thanks

HP 7900A on ebay

by jwest＠classiccmp.org

Search Ebay for "7900A" and you'll find it. Missing front screen. There was a day when I'd give most anything for one of these. Now I have a good supply so I thought I'd mention it in case anyone needed one. Anyways... the 7900A is one of the few HP drives that doesn't use a sector surface, it uses a glass reticule. If someone gets this drive and it needs work, let me know as I do have all the service manuals. More importantly, the 7900A is supported on most versions of TimeShared BASIC, including the "E" version which only needs one cpu. Regards, Jay West

Geek-Stuff places in LA

So I came out of LAX, "Turned Right" (toward the ocean- west) at the branch - went a distance, "Turned left) (south) on some street - and found on the right hand side a very "Weirdstuff" like place? That same street continues and becomes another freeway that I had to take to get to my work-site in Compton. Anyone know where I was? Any other electronics-junkyard type places in LA? It has just occurred to me that LA is only 3 hours away...Road Trip! :^)

Need pinouts for MDB Systems DLV11J serial line interface

by vcf＠siconic.com

I've got a serial line interface in this LSI 11/23 system I've got here. It's made by MDB Systems and is model DLV11J. I've got the manual for the DLV11 but it gives the digram for one big 40 pin Berg style connector, whereas the DLV11J has 4 10-pin Berg style connectors. Does anyone have the documentation for this? And now for a really stupid question: Can the 11/23 run RT-11?
