SMC 2010, 2009 & 3007 dip chips???

by Innfogra＠aol.com

The 2010 discussion is interesting to me. I have a SMC 2010B with a date code of 7736 in Ceramic with gold legs. Is this a second source of the Western Digital or something different? I also have a couple of similar chips by SMC, a Plastic/gold 2009H with a date code of 7942D, and a Plastic/gold 3007-A01 with a date code of 7852A. This one has a P.N. of 27-001 on it also and is a 28 pin dip. The first two, the 2010 and 2009 are 40 pin dips. All seem to be limited production run chips as I have not seen others of them. Paxton

CP/M 1.3 memory requirement

Sounds like you need more ram. Get another 16k for safety. A cromemco ram16 or ram17 should be easy enough to find or other 64k static. Allison

New finds & the Woz!

by jbmcb＠hotmail.com

Picked up an Intel brand Pentium 100, runs OS/2 nicely. Also found a DEC MicroVax II with 2 4-line serial controllers. No drives, but I have a few spares. Time to froray into VMS. Last Sunday I went to see the Woz speak at the Mac Group of Detroit. Fascinating speaker, if anyone has the chance to see him I highly reccomend it. He talked in-depth about working at TI, designing Breakout with Steve Jobs for Atari, and designing his own computers at the Homebrew Computer Club. Most fascinating factoid: He was inspired to make his first TV-display terminal when he paid a visit to Captain Crunch and saw that he had a Teletype in his apartment, and was "Talking to some guys in Boston!" over Arpanet.

Diskette compatibility question.

by forslund＠tbaytel3.tbaytel.net

Hi, I have only one diskette that came with a Heathkit H89 computer. It's a soft-sectored 5 1/4" Dysan 107/1 flavour. I also have a couple boxes of "newer" 5 1/4" diskettes that i used in the IBM pc world, which are also soft-sectored, but are double sided, and single or double density. I am wondering if i can reformat these (in CP/M for example) and use them in the H89? It makes sense that i should be able to do this, since they're obviously better quality (ie. can store more info) than the older SSSD's, but I'm not sure if I can do this. I would test it, however, at this time, i don't have format.com for the H89. Thanks Bob

The Lifeboat NS* dist for 1.4 needs 4k more, they sorta grafted the NS* dos to the BIOS as disk drivers so it's a bit fat. I bought the 1.4 copy way back when (it was new release then). Assuming its for a NS* Horizon it will be personalized for the default NS* IO addresses. HOWEVER... it was also distributed without IO personalization. You will need NS* dos and one of the monitors or do it from the front pannel. I know I did that using the first machine (altair) before I moved to a real NS* horizon. DOCs for that version are a must or hope there is a readable example on disk. Allison

It left enough space in all cases to run sysgen(or movcpm) and leave an images in the available TPA. The actual memory needed, using the standard SSSD 8" distibution of 2.0/2.2 was 2k for the CCP (when loaded), 3584 byts for the BDOS and about 1k to 1500bytes for the BIOS. The 1.3 version was only slightly smaller. Allison

Storage idea!!!

by mikeford＠socal.rr.com

My latest bright idea, an 8x10 net (maybe 10x12) to hang from the garage ceiling to hold all my big empty boxes, bags of filler, etc. (a good portion of my garage has a 14' ceiling, so I have a lot of "room" even above head height. I'm am not entirely sure what one end will be anchored to, but I am so jazzed at the thought, that most likely I will run out first thing in the morning and buy and put up the net (anything netlike should be fine). Lets just say that right now my empty box and foam collection takes up about one 8x10 rooms worth of my garage and house.

Storage idea!!!

by mmcfadden＠cmh.edu

Regarding cargo nets attached to the garage ceiling. I also thought of the same idea, but an interesting occurrence has made me cautious. I have several articles attached to my garage ceiling, mainly sail boat parts and one had a rope release hanging on it. The dangling rope release wrapped around the front bar on the car-top carrier on my wife's van, which pulled the article off the ceiling, my wife now has a cracked windshield on the van. I have now shortened the release and taped all loose ends together. It also made me worry about some item falling onto the car if the attachment screws pulled out. I now worry less because all of the stuff is now above my car!! Mike mmcfadden(a)cmh.edu

Emergency Multics Rescue Needed!!!

by dhquebbeman＠theestopinalgroup.com

Ok, I'm forwarding this as-is. Hopefully someone has the $$$ and the will to do something about it. -dq ------------------------------------------------------------- Hello Douglas, The Multics system that was shut down today at Halifax will likely be available for purchase from Gov't of Canada "Crown Assets" soon. I should mention that the configuration is, roughly speaking, 3 x Multics CPU. Also, modifications (by Alan Haggett) had it running as Y2K compatible. ***SYSTEM WILL BE SOLD WITHOUT DISKS*** (due to security considerations). Disks are supposed to be available through third party suppliers. Serious inquiries to purchase this system as a workable system (capable of booting from tape, etc.) will only be useful for the next few days, as the current plan is to break up the unit in about 2 weeks, i.e. about 13Nov2000. The disposal of the system is being coordinated by Mr. Dave Renshaw. Please contact him for further information as per: Dave Renshaw, DND Marlant N6353 HQ Bldg D201, 3rd Floor P.O.

vms accounts

by jim＠calico.litterbox.com

Could someone give me the quick walk through on what it takes to create an account in VMS 7.2? I used to know this, but it's been a long time. The steps I remember are: 1. use authorize to add an identifier for the person. 2. use authorize to add the person. 3. create their directory. 4. use authorize to set their password and clear the disuser flag. 5. log in on squeeky clean new account. The problem is, I have an account on my vaxstation, but either I never managed to get it to work or I forgot thet password. The security alerts that come up in audit server tell me my password is bad, even when I'm typing in what I just used authorize mod jim/password=<whatever> to set. Thanks. And I have to say ELM looks somehow more *right* on a vt220 amber monitor than it does in a window. :) -- Jim Strickland jim(a)DIESPAMMERSCUMcalico.litterbox.com ----------------------------------------------------------------------- BeOS Powered! -----------------------------------------------------------------------

I'm back! (and other things)

by netsurfer_x1＠hotmail.com

First of all I'd just like to say a big hello to all the group members. Yes, I did make it through boot camp, & now I'm up in Groton for sub school. Anyway, I was wondering if anybody had a working Apple Newton 2100 (or upgraded 2000) with all of the stuff it came with (dock station, CD, stylus, manuals, etc.) that they would be willing to let go for cheap. Can you help me? Also, if the Newton has the keyboard, I don't want it, but if it has a carry case, I'll take it. ____________________________________________________________ David Vohs, Digital Archaeologist & Computer Historian.

The specifications about the first Multics let me do a virtual disk from 4 Millions of words of 36 bits. There is an study about the modules that compounds the kernel and the recommendations to reduce its size. I have some source code in PL/1 of some Multics utilities and a list of 314 commands like appears in http://www.multicians.org/multics-commands.html ... I only needs the messages of the commands to simulate them but logically I should agree the source code :-) And, in other way, the mechanism of console or terminal session that Multics used. That's all for now. I prefers at this instance to made an hipotetical machine that runs the System before than a real General Electric 635/645. Even I'm not interested by now in the security mechanism that were developed later. Well, that's all for now. Thanks for your kindly answer, Douglas.

DEBNT installation

by jate＠uwasa.fi

Here's the DEBNT installation from VAX 8200/8300 Installation Guide. I really remembered that I had the real docs for DEBNT but I can't find them at the moment, anyway here goes: 4.8 DEBNT INSTALLATION 1. Remove processor cabinet front and rear doors 2. From the rear of the processor cabinet, release the BA32 box track lock (Figure 2.14). 3. Slide the BA32 box out of the cabinet. 4. Remove the BA32 box top cover. 5. Insert the T1034 module in the VAXBI cardcage. 6. Rotate the BA32 box up and remove the bottom cover. 7. Install the transition header on the backplane if the slot holding the T1034 module. 8. From the rear of the BA32 box, open the appropriate cable restraint and feed the transition end of the DEBNT cable into the box. Pull enough of the cable into the box to feed the cable under and through the rear brace and up to the backplane of the slot that holds the T1034 module. 9. Connect the DEBNT cable to zone E (left) of the transition header on the backplane of the slot that holds the T1034 module. 10. Connect the 12V power cable from the power supply distribution board to the pigtail connector on the DEBNT cable. 11. Close the cable restraint at the rear of the BA32 box. NOTE Route the DEBNT cables separately from the power cables insider the processor cabinet. 12. Replace the BA32 box bottom cover. 13. Rotate the BA32 box down. 14. Connect the DEBNT cables to the distribution panel. 15. Replace the BA32 box top cover. 16. Power up the system. The DEBNT self-test runs upon power up. Check that the yellow LED on the T1034 module lights. If the yellow LED does not light, refer to the DEBNT Ethernet Tape Controller Technical Manual. 17. Refer to the DEBNT Ethernet Tape Controller Technical Manual for the complete acceptance procedure. 18. Slide the BA32 box into the processor cabinet. 19. Replace the processor cabinet front and rear doors. -- Jarkko Teppo jate(a)uwasa.fi

VAX 6000 available in Austin, TX

by mrbill＠mrbill.net

I've got a VAX 6000-410 (complete with everything BUT disk controller and HDs; this has 2 x 32mb RAM cards and CPU, etc, but was used as a cluster node) that I picked up a few months ago intending to ressurect it and play with it occasionally, but a couple of things have stopped me >from doing that: 1. Hot as hell in the garage in summer in Texas. 2. Cant find the plans to convert from 115V 3phase to 220/240V single 3. No available outlet for it when I *do* find the plans to convert it. (adding another one turned out to be prohibitively expensive). 4. No time!!!! Anyway, if anybody on this list within driving distance of Austin, TX would like a free (well, something in exchange would be nice, smaller VAXen, ham radio equipment, etc but if nothing lse, come get it and its yours) VAX 6000 system, let me know. You'll need at least a small pickup truck and at least two people to load it into said truck; its fairly heavy. I'd help, but I'm still under doctors orders to not lift anything major for another few weeks (pulled ligaments in my wrists while rackmounting a Sun E450 @ work a couple weeks ago). Pictures of the VAX (along with serial #s, card inventory, etc) are up at http://www.decvax.org/vax6000. I'm not gonna junk the machine, but someone could be getting more use out of it right now than I can... so until it finds a better home, its in the garage.

Reading Xenix backups

by jhellige＠earthlink.net

Seeing the mention of the Shugart QD floppy drive brought to mind an Altos 586T that I used to have that used this drive, along with a Wangtek 60MB streaming tape drive. This was an 8086 based server released around 1983 that ran XENIX and used a number of Z80's to handle the I/O on both the serial ports and disk subsystem. I no longer have the machine itself as it was horribly corroded by the time I got it, though I do have a replacement Wangtek tape drive and a copy of the XENIX floppy disks for it, as well as two 3M DC300XL/P data cartridges that supposedly contain a full system backup. Short of finding another 586T, is there any way of at least checking the data integrity of these tapes? thanks and take care Jeff -- Power Computing PowerCurve, 400mhz G3, Mac OS 9.0.4 Collector of Classic Microcomputers and Video Game Systems: http://www.geocities.com/siliconvalley/lakes/6757

It was the rare and maybe only thing Zilog did right and that was persuing the embedded market back around 84-86 timeframe. That was the breakpoint for PCs taking over and Z80 based systems and their like starting to loose influence. that and the Z8 business kept them going. The next big break was the Hitachi licensed 64180 (z180) giving the embedded designer a MMU, sio, DMA on chip and it was a little faster. I see things like that as important to the evolution of the microprocessor market and the chips. The same forces would also keep the 6502 in the running. Allison

But kinda cool in a way. Actually the raw Z80 is not seen much in new designs but it's later fellows are very much there. It's one of the most commonly available of the old line CPUs. If the 6800 were still available from Moto (68705 is) it would be used still as is the 6502 decendants. Like PDP-8, PDP11, VAX, Nova, 6502, 6800 and many others a good design is hard to displace. Oh and the CMOS 8085 also went to mars to push rocks around very successfully (mars rover). Allison

The TEAC 55F does that natually and the 55GFV jumpers to that mode easily. The latter was used for DEC RX33, PC 1.2mb and a lot of other uses so it's pretty easy to find. I have a pot load as it's about the most versitle drive in the 96tpi class. The mitsubishis are a good second choice and also widely used in PCs. >For half height, I like the Shugart/Panasonic 465, although not everyone >is happy with those.

And as the plain ole Z80 as well. The embedded systems world is crazy about it, using it all over the place. I know a guy (younger fellow, just out of college, only learned what the college decided to teach him, very naive) who works for a defense contractor...sent me email the other day asking if I'd see the neat "NEW" processor called the Z80. What a great embedded processor it is, he babbled. He was quite pleased that someone finally came out with a really nice cpu that had an instruction set that made sense for the embedded world to use. He just hates the PIC and the 8051. (I don't know what his problem is, I like 'em both a lot) I explained that I was running a Z80-based general-purpose computer fifteen years ago (an IMSAI with a CCS Z80 CPU board which I still have) as my main machine, and that the Z80 processor was a general-purpose machine that was very popular in the 70s and 80s...and was definitely nothing "new". Know what? HE DIDN'T BELIEVE ME!! So, yes, folks...the Z80 seems to be gearing up for a second life...this time as an embedded processor. There are many variations as Allison stated above, but the standard 40-pin dip that we all built SBCs out of years ago is at the head of the pack. Scary. But kinda cool in a way. -Dave McGuire

I happen to use the GFV. Before going to 3.5' drives. Also you need the drive personality board or turborom will not run in other than 40 track mode. If you have trouble finding a suitable set of drives let me know. I may add that I kept a 360k (DD48tpi) in the system as that is common media (odd disk finds I'd like to read with uniform). Also you can use 3.5" floppies (anyone that has jumper or switch for DS0-3). Use them with 720k media and it's nice. Another trick is to put a 3.5" drive internal and treat it like a hard disk. This is my current config and that gives me roughly 1.8mb of space (A:781k, B:360k, C: 781k). One of the CP/M oddities is once you get drive size orver 500k space as a problem seems to drop off quickly as an issue. Allison

I dream in 8080/85/z80 so its no big deal to write a 1k monitor. It's likely easier now as I have a basic monitor on hand that ive used for years and could be tweeked for that. Of course any of the published monitors for 8080 like the LLL AMS80 (KILOBAUD) monitor will do as well. If you have Burskys book The S100 bus handbook there is a copy of Vector Ones monitor in there. A monitor for a a ISBC80xx or BLC80xx is a rather basic thing and should easily fit in a 2716 (I've done nice ones for 2708!). >Aztec, BDS, Whitesmith, among others, are all history. <sigh> Maybe the >"small-C" (Hendrix) could be used, since I can write my own code generator. >I'd rather skip that step though. small-C _IS 8080_! that was the original version, it was later that z80 code generator was created.

Unfortunately the Montegar CD-ROM is a mess when it comes to kits, some have kits some don't, very sad. Here are some clues: You can get a directory of the CD by mounting it and typing: $ DIR DKAxxx:[000000] (note that is six zeros) You can leave off the zeros when you find a directory, ie : $DIR DKAxxx:[TCPIP_VAX050] If you find a directory full of savesets (they will be named "foo.A foo.B foo.C etc") then you can install them with: $ @SYS$UPDATE:VMSINSTAL foo [directory spec where the save sets are] So for TCPIP it is $ @SYS$UPDATE:VMSINSTAL TCPIP_VAX050 DKA400:[TCPIP_VAX050.KIT] Note that KIT is a subdirectory of TCPIP_VAX050 and you need your CD-ROM's target not mine :-) If on the otherhand you find a file that ends with the PCSI extension, then that is designed to be installed by the PCSI system. You do that using: $ product install NAME /SRC=[directory] Note if you don't know what its name should be (and believe me it can be tough to guess some times) then just type: $ product install /src=[directory] And when it asks for a name type * there will be only one choice and it will be chosen for you. > Basicly I have navigation troubles. Yes, there are those "logical" names versus the "real" name of the drives. Some clues there are : [000000] is the root directory [foo] is a file FOO.DIR in the root directory [foo.bar] is the file BAR.DIR in the FOO directory Typing $ SET DEFAULT [directory spec] Is like doing a "CD to directory" and typing $ SET DEFAULT [-] Is like typing "CD .." --Chuck

This board is a Multibus-I type with an 8085, 8251, 8253, 8259, and a pair of 8255's. Intel shipped a monitor prom which I turned over to a customer many years ago, thinking I'd never need it again ... <sigh> ... I guess you never know.

Please respond directly to the gentleman below instead of me... bill ----- Forwarded message from Dominic <dominic(a)altoona.fsnet.co.uk> ----- From: "Dominic" <dominic(a)altoona.fsnet.co.uk> To: <mrbill(a)pdp11.org> Subject: PDP11 Computers Date: Sat, 28 Oct 2000 19:02:54 +0100 Hi ! I recently rescued alot of computer stuff from a breaker here in the UK. Everything that was there I took away. The load has some PDP11 bits: 1 x PDP11/73 Model 1730A-B3 SER No. AY00934 1 x PDP11 Model 11A23-R SER No. AY07507 Both are 120/240 Volts AC in on power supply, both units are complete except they are both missing the plastic cases. They were removed ready for the units to be pulled apart, Luckly I got there when I did, BUT some others were not so lucky and were already in bits. I managed to collect: PCB BOARDS: M7555 x2 M8043 x2 M7954 x1 M8049 x1 Also a "Realtime Clock" card ???! There are also large boards: M8067 x4 M8189 x2 Misc Bits: 1 x Rx50 -AA revc Dual 5 1/4" Floppy drive 3 x AA12B1 ASTEC power supply units, Digital code H7864A 1 x Digital VDU inc keyboard type VT320 2 x RS232 cables to connect VDU to 'Console' skt on computers. Both the PDP computers work, the 11/73 boots up ok on its RD52A Hard Drive, runs through a mass of loading commands then says 'Have a good afternoon'! rebooting it gets it to request a login and password. I have not managed to get in despite several attempts. The other goes through its startup routine, then asks for a boot disk. I returned to the breaker and tried to find some but was told all disks had been thrown away - typical! The unit has a hard drive but its labelled 'Cleared by Digital' so there is probably nothing on it anyway. It's so sad when gear goes for scrap, even working stuff - such a waste. I am based in the UK in Norfolk near LOWESTOFT on the EAST COAST. I don't know where you are but if anybody wants these items they can have them, no money required! Happy Christmas! Dominic. ----- End forwarded message ----- -- Bill Bradford mrbill(a)mrbill.net Austin, TX

INS8154 used in Cytospin

by ajp166＠bellatlantic.net

The INS8154 is a programable parallel IO device and 128 byte ram. There are no substutes I know of, as it was single sourced from National Semi. the alternate would be to try and find new unused old stack or make a substitute using TTL and ram devices that are avaiable. I know the device though, I have two I bought for use 20 years ago.

HP 125

by Innfogra＠aol.com

In a message dated 10/27/00 5:46:42 PM Pacific Daylight Time, rigdonj(a)intellistar.net writes: > Hey, I have one of those. It's the same shape and size as a HP 9816. > It's a great little CPM machine. Don M. has a lot of software for it and I > have some of the SW. Somebody has got to save this one! Joe; You are thinking of the 120, that is the one that looks like the HP 9816. The 125 looks like a terminal on a square goose neck. The 125 is a great CPM computer. However it uses it's own keyboard which I don't think goes with anything else. I hope the keyboard is there. I also think it uses drives with the large HP connector that looks like a centronics. I am not sure if it has HPIB. I think it came before HP standardized on HPIB. I used to have one many years ago. Paxton

Was it 110, 135, then 300?

by xds_sigma7＠hotmail.com

OK, according to "Technical Aspects of Data Communication," John McNamara, Copyright 1977 by Digital Equipment Corporation, these are speeds for asynchronous communications (doesn't seem to have a sync table): Five bit: 45.45 50 56.86 74.2 75 91 Six bit: 45.45 48 49.1 55.21 56.75 56.86 60.6 66.67 69.25 74.2 80 135 Seven bit: 45.45 56.75 61.35 67.34 74.2 75 76.92 100 134.5 <- IBM 1050, 2740, 2741 std. speed (selectric-based terms) 600 Eight bit: 45.45 56.75 67.58 73.33 74.07 74.1 74.2 84.61 100 110 135 150 165 Model 37 TTY for Western Union then 300 up to 9600 For stop bits, the book lists 1, 1.42, 1.5, and 2. The difference stop bits are what make for such weird numbers, though some modems have even more bizzare rates, such as 200 (top speed of British Post Office Datel 200 service), and 1800 (top speed of Bell 20-type modems).

Tango Schematic capture, PCB layout and autorouting programs

by rigdonj＠intellistar.net

I was in a library book sale store yesterday and found the complete packages for Tango Schematic (schematic capture program), Tango Route Plus (autorouting program) and Tango PCB Plus (PCB layout program). These date >from about 1991. Has anyone used them? Are they any good? I was out of money so I went back early today to pick them but someone had taken the Tango Schematic. The funny thing is that all three were in a box together and they didn't take the other two. What's nore, they require a dongle and the dongle was in the Tango Route package so they can't even run the Schematic program. I went ahead and got the other two programs. Has anyone got a copy of Tango Schematic that they're willing to part with? Why was I out of money? Because they also had "Bit-Slice Design: Controllers and ALUs" by White and "Bit-Slice Microprocessor Design" by Mick and Brick and some other GOOD books and I spent my money on those first. FWIW both of these bit slice books are VERY good and very easy to understand. I highly recommend them. One of my other COOL finds there was a September 1977 issue of Scientific American. It's filled with articles about microelectronics (almost completely computers). There's also a LOT of ads from the various S-100 computer manufactures. BUT the coolest thing in it is an article (Microelectronics and the Personal Computer) by Alan Kay. Alan was one of the guiding lights at XEROX PARC. This article has a pile of pictures and information about XEROX's then experimental graphical computers. It even mentions a new pointing device called a mouse. Does anyone know what that might be? :-) Joe

It would go up to 600 baud using the Bell 202a encoding. I learned how to whistle the carrier tone by playing with it. I could not only whistle the carrier, but with a little modulation, I could get garbage to display on the screen of a connected terminal. Kept trying to learn to whistle "Hello" but whistling ASCII ain't whistlin' Dixie... ;-) -dq

It's listed in the Hardware Manual (and mentioned no a couple of web sites). You connect a terminal (or PC or Mac) to the serial port (VT100, 9600 baud, 8N1), set the Ethernet switch to "test", power the GatorBox, and you should get a menu. Select the code memory test, which wipes all the settings. However, you will need to re-install the GatorShare software afterwards, which will require a Mac and a "download server" (could be a TFTP server). -- Pete Peter Turnbull Dept. of Computer Science University of York

Q: Third-Party Unibus Memory Boards

by mcquiggi＠sfu.ca

Hi Gang: This morning I was sorting through a bunch of my spare Unibus cards, and noted that I have at least half a dozen RAM boards. These are all, to my knowledge, Unibus cards. These are not documented in the DEC Field Guide (thanks to Megan for her diligence in keeping it relatively current). In the short term I'd like to find out the characteristics of these cards, and their compatibility, in the longer term these 3rd party cards should be added to the Guide. Here's what I know: 1. Plessey Peripherals 705075-100 Rev B. Hex height card. 2. Standard Memories MM-140 PD Rev C4, also marked 102415-442 and stamped "20272" in large (3/8") white letters. Also a hex card. I have about 5 of the former, and 3-4 of the latter. My motivation for this exercise is to find a card that I can use to swap out the 128 KW RAM board on my (sick) 11/34A. This card is a M7891-DB, 128 KW 18 bit parity RAM. If either of these cards are similar in config (size < 128KW is irrelevant as I just want to see if I can get the machine to boot) then great, otherwise at least I can label the boards, and ask Megan to add them to the Field Guide. Thanks, Kevin -- Kevin McQuiggin VE7ZD mcquiggi(a)sfu.ca ---------- To unsubscribe (or subscribe) from (to) this list, send a message to info-pdp11-request(a)village.org, with the first line of the message body being "unsubscribe" or "subscribe", respectively (without the quotes).

PET keyboard

IBM P70

by SUPRDAVE＠aol.com

--speaking of P70s and such-- I've v3.0 running on the P70 and would recommend it. There was lots of fixpacks for v 2.x I've never had trouble installing OS/2 on PS/2s. They are made for each other. Probably some of the easiest installs I've had. If you can find warp connect, install that as it's more up to date than v.3 or at least install blue box version 3 and run as much memory as you can.

Mac TCP/IP networking (was Re: old MAC's)

I have a GatorBox CS (you can still get software updates from Cayman's FTP site), and although I've never tried this, it is supposed to be able to allow Unix machines (or other machines that talk TCP/IP) to print to Laserwriters on the Localtalk bus. We used to have two at work which allowed Mac users to use our Unix printers and Unix/NFS filestore (which suggests it does translate properly in both directions). They also allowed our Macs to talk to others on the campus, which involved going through at least two IP routers and the ATM network as well as the two ethernet segments and GatorBoxes, though I think that used some sort of tunnelling mechanism. And of course all the Macs, PCs, and Unix machiners could ping and telnet to each other, though I'm not sure how much of that involved the GatorBoxes and how much was done by software in the Macs. We no longer have/use the GatorBoxes at work, though two other Departments still do, I believe. Our Mac users use Dave to talk to the print servers and file servers. I don't know much about it, but I think it's a sort of Samba client -- doubtless some of the Mac users on the list know much more than I. -- Pete Peter Turnbull Dept. of Computer Science University of York

DEC RP06 power

From: Richard W. Schauer <rws(a)enteract.com> >I've recently acquired an RP06 as part of a PDP-11/44 system, and I wish >to run it (why not?) I remember reading on this list a while back, that >it could be operated on single-phase power instead of three-phase. I got >a printset along with the drive, and it's pretty unclear about what would >use the three-phase- it's almost like the third phase is ignored, the 208v >between the first two phases is fed to the transformer, and the primary is >sort-of center tapped to feed the 115 volt fans. Is this right? How >would I go about feeding it single-phase if that isn't right? Rewire. The reason most of these devices use three phase is to distribute a load more uniformly over what was a normal power system in computer rooms then. Also many of these devices have a rather harsh startup current and slicing it two or three ways makes it much easier for the sytem (wiring and power circuits) to sustain. For example a lowly MVII in a BA23 has a startup surge of over 100A for one cycle (about 16mS). In the second 16mS that might be only 12A and by the 10th your near nominal of say 3.2A. If you turned ten of them on at the same time and same circuit the running current is maybe 32-40A but the starting current could easily exceed 1000A for several cycles. Why? If they were all on one breaker the whole load would attempt to bring the caps in the power supply up that first 16mS... save for the 10,000A surge would pull the 115v down to say 60V (assuming thick wires and the fuses held!) the next cycle would be needed to charge those caps more, likely 10 or 15 cycles so the huge current would take longer to dissapate. Add motors like the RP06 with their nasty starting currents and you see why power systems were so robust. Granted the startup condition is pathological as no one would do that (staggered is also common) but the need to distribute the sustained load is also important. If I had a 6000, I'd ahve rewired it already and could tell. Most often (but not always) three phase power is used as independant legs. Exceptions would be beasties like VAX9000, PDP10s and other power hungry older machines. Allison

They all have limitations, and it's a long time since I used any of them, but if you want to contact me off-list, maybe we can compare notes and get something going. I've got all the manuals, and a CS to talk to, though not a Mac to run the software on at the moment. -- Pete Peter Turnbull Dept. of Computer Science University of York

I've had great luck with Netatalk (except for having to reboot the Linux box all the time when making network changes). When it's running, it runs well. I happen to have this ancient Appletalk card - DB9 connector and all. I remember researching it a couple of years ago and there was some interest in Linux drivers.

old MAC's

by richard＠idcomm.com

I've begun to see numbers of old Mac's in the various thrift stores. Which models are particularly interesting? I've never had much of a taste for the things, but at $6-$10 each it might be worth snagging the things just for the disk drives, or some such. Today I ran into a classic, a ii-lc or some such and iii-si or something like that. These latter are both those recent-looking low-profile thingies. Do they have anything of interest in them? Dick
