Re: Large cache of classic computer in Umeå, Sweden

by lee_courtney＠acm.org

Hej G?ran, There's always donation to IT-Ceum in Link?ping. Kinda far away, but still in Sweden and a nice Museum.

LIST ADMIN

by jwest＠classiccmp.org

Greetings Folks! As many of you noticed almost a year ago, we started having issues with the classiccmp server. Some of these were hardware issues, some software, etc. Due to the extreme generosity of Al Kossow, a new server was recently provided for the list. It is a very nice 2U dual cpu 2.2ghz opteron with 4gb ram, dual gigabit ethernet, and six 300gb hot swap ata drives. Two of the drives are mirrored (gmirror) and hold the OS (freebsd 7.1) & software. Of the remaining drives, 3 are in a zfs raid5 pool and one drive is a hot spare. These drives hold the websites, ftp sites, mailing list data, etc. Over the past few weeks I've been working to migrate all the classiccmp-related websites that I host on the server to the new machine. Last I did the classiccmp.org website (which means the archives were unavailable for a week or two as they existed {and were still being updated} on the old server). A day or two later I migrated the archives and finally yesterday - the list itself. To the best of my knowledge, all should be up and running well. There is *STILL* a problem with the htdig indexing of the lists. I am going to finally dedicate some time to researching that. I've been putting it off for eons because I've mostly forgotten everything I used to know about HtDig. I still have to do a little work to get metrics back up, unfortunately my favorite tool (mod_watch {interfaced with cacti}) is no longer supported so I may be looking for a new tool along those lines to implement. If you have suggestions, please email me off-list, I don't want to start a long off-topic discussion of modern hosting tools. I would like to post a list of all the classiccmp-related websites, ftp sites, etc. that are lurking on the server, as I suspect some are not commonly known. Everyone who has things hosted on the classiccmp server is aware of it - so if you object to me posting your URL please email me within the next few days and let me know and I'll omit your site. I'd like to take this time to re-iterate my offer to host any classic computer related websites, ftpsites, mailing lists, wiki's, blogs, etc. at no charge. I don't want to run the site, I just provide free hosting and bandwidth - the site is still yours. The server is in a world class datacenter with serious bandwidth - not on a DSL line in a basement or anything :) Along those lines, several people recently asked to move their classic computing sites to the server and I asked them to wait till the new server was up. We have gobs of free disk and the machine is reliable now, so re-contact me and we'll get it up and running. My classiccmp email address got to a half gig, it will be a long, long time before I skim through it. However, I have put it into a different mailbox so I can definitely see any new emails to my classiccmp address and will keep on top of those. Or attempt to :) I am trying to get back to things classiccmp related - as well as actively reading the list again instead of just watching the server. I departed for a while due mostly to classiccmplist-burnout and "work stuff". The work stuff has mostly settled down, and I find myself very much wanting to dig back into my beloved DG's, HP's, and yes, even the DEC's </troll> My last acquisition was an excellent Data General Dasher D200 terminal, which will look awesome sitting next to the Eclipse S/130. Next project is to make room for a metric boatload of 800/1200 DG minis and get them here instead of storage. Glad to see all the familiar faces, as well as some new ones. Best regards, Jay West

(DEC certainly tended to standardize > this sort of thing company-wide.) Yeah. I can report that RSX do the same skewing/interleaving as well. And to make the point even clearer to the original poster: this is not something simh is aware of, or involved in. This is a mapping algorithm done by the PDP-11 in software (in the driver). So it definitely applies in this case. Johnny -- Johnny Billquist || "I'm on a bus || on a psychedelic trip email: bqt at softjar.se || Reading murder books pdp is alive! || tryin' to stay hip" - B.

Progression of search technology (was Re: The lost art)

Which sort is "better"? "Shell-Metzner" or > "shaker"? In the past couple years Google and Amazon return search results to not just the title or author, but the text in the book if it has been OCR'ed or was originally electronic. Obviously Google knows a lot about efficient free-text searching but other folks know it too. In the past 15 or 20 or maybe even 30 or 40 years in the right circles (I do not hang around in database circles! But I was using Rdb a while back) the catalog would be loaded straight to an indexed database with several keys arranged for easy alphabetical sorting. The indexed database might even be smart enough to allow free-text or associative searching through some clever trickery. Even if there wasn't an index on the field we wanted to sort on there's probably the SQL "ORDER BY (whatever)" keyword. I will admit that databases can do some spectacularly slow things if you build your indices wrong, and even the most expensive version of Oracle can suddenly become much slower than an Apple II running a linear search on a cassette-tape file in the hands of the clueless. In the past 10 years or so, I'd just say (in Perl) "sort keys %hash". Surprisingly until fairly recently this could, worst case, be a quadratic sort but they recently put some tricks in (preshuffling) so this will basically never happen. If I was interviewing a recent CS graduate I would expect him to not address the problem of a card catalog index by talking only about sorting, I'd expect him to know some of the newer technologies - databases with keys; maybe even knowing about hashes if I ask about how a database implements an index; possibly knowing about the indexing technolgies allowing free-text searches. If he started talking about bubble vs shell sort I would go "OK, you got the points for knowing about sorting, now teach me about this new stuff" about 10 words in. If I wanted to know what he knew about how algorithmic complexity I'd ask him about bogosort which probably they didn't teach him about in school, but would give him a leg up if he had been reading or maybe even contributing to the Jargon File for the past few decades. If a candidate agreed with me that buying Oracle got the governor of California fired, I'd hire him on the spot. If I had a new hire and I saw him writing any sort algorithm, I'd teach him how to do it by using one already built into the system. Tim.

Looking for Compaq LTE (8088) power supply or voltages...

by derschjo＠mail.msu.edu

I've got an old Compaq LTE (I believe it's the original 8088 variant, but I can't find a model # on it anywhere) that I'm trying to recover some files from for a friend. The power supply is long gone. The hard drive is certainly some proprietary interface, so I'd prefer to try to get the laptop running before I try to take it apart and read the drive in something else. Anyone have a power supply for one of these, or know what voltages it takes? (It has a 4-pin power connector, don't know if this style of connector has a name...) Thanks, Josh

free stuff from Milwaukee Wisconsin

by frustum＠pacbell.net

I sent this a couple weeks back, about when the list went down for a few days. I'm not sure if it was received or not. There were no inquiries, so either nobody wants S-100 stuff these days, or the message didn't get out. Sorry if it is a dup and nobody is interested. A gentleman contacted me and said he had some things that his brother had made/used back in the day, but he wanted to find a new home for them after his brother died. I have given away my S-100 stuff, so I have no use for it. He doesn't want his email address on the web, so contact me and I'll put you in touch with him. Al Kossow, this stuff is coming from Bob Senzig -- this was his brother Don's stuff. 1) Z-80 CPU 2810A assembly number 02810001A (mfg) 2) Model 2422 multi mode floppy disk controller assembly number 02422-001 rev B (mfg) 4) Data technology 018A000 rev 2 (manufactured) 5) Vector Graphics 64K RAM Assembly number 3504 (mfg) 6) Vector Graphics serial card ZCB (mfg) 7) Processor Technology Co. 2KRO (hand wired) with boot PROM 8) GODBOUT 4K static RAM (hand wired) 10) Vector Graphics floppy disk drive disk controller assembly number 356500000600 (mfg) 11) Altair DMA interface 1976 (hand built) 12) Processor technology 4K RA (hand assembled) 13) 4K static RAM by Solid State Music 1976 (hand assembled) 15) Extender card (hand assembled) 17) IMS Associates Inc 1976 CRI rev 1 Audio interface board (hand assembled) 18) Godbout 4K byte RAM module (hand assembled)

PLM86 compiler needed

by dmabry＠mich.com

Ok, I have found the 8" floppy disk with the ISIS-II PL/M-86 compiler on it. It is transferring at the blazing speed of 2400 bits/second using Kermit protocol into a PC. From that point I will be able to send it to a computer that sends my e-mails out. So we wait for 2400 bits/second to transfer the plm86 compiler with its overlay files. It really is slow. I love the technology, but it is slow! Stay Tuned for Updates! Jeff Erwin said the following on 4/11/2009 6:42 PM: > Yes, I do!

PLM86 compiler needed

by jefferwin＠gmail.com

I purchased the Godbout 85/88 card for my Imsai 8080, seems to be working fine so far, although not at 5Mhz. I must have a memory card that can't handle the blazing 5 Mhz access. I am looking for a PLM86 compiler. I have the PLM80 compiler and linker/locator (if anyone needs this, please let me know) but am struggling finding the PLM86 compiler and associated linker/locator. I am currently loading code into my system via a HEX loader I wrote and sending the hex file in via the serial port >from my Mac Pro (yes, a $5000 quad-processor computer serving as a dumb terminal to my 2Mhx 8080). I want to be able to write PLM86 code and do the same for the 8088 on the GodBout card. Anyone know where I can find PLM86? Jeff Erwin
