Just because some people commonly refer to it as DB doesn't mean it's correct, after all lots of people call the standard 9-pin shell a DB. Amp, for example, refer to their entire standard series as "DB" but that's not what most other manufacturers do. McMurdo refer to the type used for VGA as HDE15 (and the next sizes up as HDA26 and HDB44) which seems much more likely to be correct.

AtariTel prototypes found

by vcf＠siconic.com

I just posted a bunch of pictures of some prototype Atari stuff I found today at a local electronics flea market. Thanks to Curt Vendel's Atari Historical Society website (http://www.atari-history.com) I've learned that they are prototype boards for AtariTel, which was supposed to be a breakthrough new business phone system but Atari never released it. I have what look to be the initial raw prototypes and then etched prototype development boards, and then an almost complete phone (missing the handset and top cover). There's also a hacked handset used during development and a rough prototype of the case made from plexiglass. From the scanned preliminary product description document found on AHS, I learned that the project inception was in 1981. The boards I got have either 1983 or 1984 copyright dates on them. There was also an unlabeled hacked carthridge in the pile (not pictured). I don't know if the ROM is still good on it though. It's been in a pretty rough climate. If it does work I imagine it has some interesting code on it perhaps. The whole pile of cards looked as though they had been sitting in a box outside under a tree or something. The solder traces were starting to corrode and chip leads starting to rust. I cleaned off a lot of bug and leaf debris and lots of dirt. It's a shame they had to be stored like this, but I guess the guy who designed this stuff didn't think it was significant. Also in the pile were some odd items. There was a board labelled "Misty 001". Is this related to something else? There was also a home-made acoustic coupler box. I don't know what it's purpose is, but it had an Atari serial connector on the back. Both of these are pictured. The photos are at: http://www.siconic.com/crap/AtariTel Sorry I didn't label the pictures properly. You'll just have to go through and check them all out if you're at all interested in this. It was really cool discovering this stuff. In their heyday, Atari hand their hands in everything it seems.

They should use the panel. There is a 10 pin header that is nestled between the power plug and the 50 pin DSSI plug, that is where a 10 pin cable goes from the drive to the back side of the disk bulkhead. That also sets the unit numbers for the drive. Perhaps someone set them up to override the unit numbers because they were short of plugs or something. When you type 'sho dev' they show up as DIAxx what numbers do the drives show up as? >Mine seems to have a standard 4 connector cable. If I made a cable, how >many memory boards could I use? As many as you can fit, however the CPU is limited to addressing 64MB of RAM so you can't get more than that. Also the 4MB disables itself if you install a full 64MB (4 x 16MB is common) >> The 4Plex should work fine on it, *if* you have a SCSI interface in there. > >Good. What should I look for in a SCSI card? Existence. :-) Actually SCSI cards for this beast aren't hard to find, they are just hard to afford for many collectors. You want a SCSI card with an 'sbox' handle. Examples are the Emulex UC-08, CMD CQD-223, etc. I prefer the CMD ones but Emulex, Dilog, and others made them. You can buy them all day for $500 each from DEC resellers. On Ebay they go for less than $300 usually, and of course if you buy a couple of tons of VAXen before they get scrapped you can often salvage one or two. I sold one as part of a cherry 4000/200 and now I kinda wish I hadn't (I just got a VAX 4000/700A that I _really_ would like to put a SCSI drive on.) If you get one with non-Sbox handles you will either have to adapt a blank Sbox "bar" to mount the connector or you will have to run the cable out from between the bars. I've done both. Alternate mechanisms to getting a SCSI CD-ROM are to get an RRD40 controller (slow but it works!) You may be able to find a DEC reseller who will sell you the drive and controller for less than $100. > When I do get a SCSI >card, should I remove the TK70, or just mount the cd-rom in an external >case? I would like the cd-rom internal, but I don't know how important >that TK70 might be. No doubt the TK70 will be critical if you find a piece of software that only comes on the original TK50 media. I prefer my VAXen to sport a TKxx drive. Something I've been doing lately is making 'vax boxes' which are 2 unit SCSI cases with a VAX compatible CD-ROM drive and a removable SCSI drive. Then I get a couple of trays for the SCSI drives (these are pretty cheap these days) and put VMS on a 200 - 500Mb SCSI disk and NetBSD on a 1GB disk (not that NetBSD is that much less efficient, just that I like room to build kernels and such.) Then one can swap out disks to run different OS'es. Mounting the CDROM in the case will be problematic and frankly doesn't get you all that much. --Chuck

Mobo Question

by chronic＠nf.sympatico.ca

Hi, I'm a long time lurker, first time poster. I recently obtained a mobo that was sitting around a local computer store, and am having a little trouble with it. It's a 386SX motherboard, with onboard parallel, serial, and PS/2 connectors. I was planning on building a little box based on this, but the problem is the lack of ISA or PCI (obviously) slots. Instead, what i have is a bigass connector. It's about 2 1/2 times bigger than a PCI slot. I'm thinking this may be an extension to plug in another card with slots, but I have no idea. Can anyone help me? If you need more info let me know, i can supply it. The brands Faraday and WDC are displayed prominently on a lot of the ICs. -Lanny

TI59/58 Diagrams aviable

by sipke＠wxs.nl

Hi Folks, TI-59/58 Diagrams !!!! (I've also posted this message on the oddcalc list) I've come accross an old schoolproject that "M.B. van der Mark" once wrote. It details a lot about the TI59 hardware. The material is very old though and cannot be scanned with good quality, it is also written in dutch. So I took it upon myself to revamp and translate this material. For starters I made a new drawing of the TI59/58 schematic. In the coming weeks (or month) I will add the diagrams for the powersupply, the PC100 Printer .... and the abbreviated translation of the rest of the material that details some of basics of operation of this marvelous programmable calculator. I will put this material on my website at http://xgistor.ath.cx Drill down to: Go Files >> Various Downloadble Files >> TI59 You can mail any comments via this list of if you prefer to contact me directly: click on the e-mail link of my main page.

FastPath

by phil＠ultimate.com

> I would really like to learn how to use these devices, so any tips on > getting started, words of wisdom RE different roms etc.? A good place to start. FP4's will probably have PROM 4.1, or perhaps 4.1.2. You can manage them from a DIRECTLY connected LocalTalk or EtherTalk (Phase I) connected Mac running FastPath Manager (FPM). [This is also true for FP2's or FP3's which were upgraded to 2U's or 3U's] FPM uses "KLAP" -- a packet with "LAP" type 0x4b (the letter 'K'), which cannot be routed. An FP4 could be upgraded in two ways; Just a new PROM (5.1), or a new PROM, and a 256K SRAM memory board (for a total of 512K), which came with a new case, and a fan. A box with PROM v5.1 can be managed with FPM, or via Shiva Net Manager (SNM). SNM only speaks KLAP over DDP (or was that ATP). DDP is the regular AppleTalk network layer, so you can speak to boxes via intervening AppleTalk routers. ATP is the transaction protocol, layered on DDP. The CPU clock on the FP4 68000, was, I believe 8MHz. FP5's started with PROM v5.0 [FP5's use their PROM only to load the "VROM" -- a protected memory version of the PROM code]. FP5's came with 512K standard, and could be built with (or, I suppose upgraded to) up to 1MB, and the CPU clock was, I believe 10MHz. The FP4 is perhaps, more flexible in the hands of a hacker, since you could take direct control of the SCC, and do async or perhaps sync serial. On the FP5, the SCC is part of the I/O Processor (a Zilog Z181), and I never did an API to load code into the IOP. All versions of the FastPath PROM provide a vector of routines which the download can call. In PROM v4 and up, this includes access to the Ethernet driver, which is how we got away with replacing the iNTEL Ethernet controller from the FP1/2/3/4 with the Fujitsu EtherStar -- the download (K-STAR) doesn't care what the hardware is (direct SCC and i82586 on the FP4, or IOP and EtherStar in the FP5). On powerup, the PROM spends 20(?) seconds flashing LEDs, then starts the download, or the built in PROM GW (removed in v5), which is a simple Phase1/LocalTalk router (with no IP capabilities). Its's best to pause or reset the box before it gets rolling, in case it's misconfigured or otherwise frotzed. Once you have it paused, you can set the configuration and download K-STAR (NOTE!! With FPM and K-STAR 8+, the Phase II zone list is sent appended to the download, so it only gets set when downloading code!! -- SNM can set the zone list any time -- although the details of how we did that escape me at the moment). AppleTalk routing; If you set VERY LITTLE configuration, K-STAR will autoconfigure, either learning information, or supplying it. If you set some things, but not others, autoconfiguration may be disabled. IP; Most people will probably want to use the box to IP-enable LocalTalk Mac's. The simplest way is to use K-STAR IP, and supply "dynamic" addresses. The Mac IP addresses will directly follow the FastPaths, so assign a big enough block. MacTCP has an option "dynamic", which you DO NOT want to use (it means randomly pick an address to use!!) -- you want to use a "server" assigned address. I can't (off the top of my head) think of any other pitfalls. -phil

Hackin' a Solbourne

by spectre＠stockholm.ptloma.edu

Well, I got my Solbourne (hi Mike!) this weekend. It's a S3000DX with 40MB RAM and runs OS/MP 4.1a. Two drives, nice box, excellent condition. The problem is that this box was production and I have no CDs to boot from, so I can't get into it in service mode so I can wipe it out. For lack of nothing better to do, I was able to "cp sd.si(,,)etc/password bw()" from the boot monitor and get the encrypted root password so that the 4-processor HP PA-RISC 2.0 L-class in the server room can have something to do other than run the school :-), but since there's > 6.6e+15 possibilities in that I was wondering if there's a faster way. It can understand UFS from the boot monitor, which is nice, and it does have a floppy drive, but I don't know what file system it expects to be on it (otherwise I'd copy etc/password off, blast the root crypt, and put a new one on -- or does this not work so good?). Any suggestions? How about hacking a Sun box with no password -- since this is a perverted SunOS machine in concept? :-) -- ----------------------------- personal page: http://www.armory.com/~spectre/ -- Cameron Kaiser, Point Loma Nazarene University * ckaiser(a)stockholm.ptloma.edu -- I couldn't care less about apathy. -----------------------------------------

Amiga questions

by JRichardson＠softwright.co.uk

a few A1200 Amiga questions (do they hit the 10 year limit? I know I got my A500 in the early 90's, and I think A3000's were around then, right??)... Anyway, here goes: Do all 1200's come with built in IDE hard drive controllers - or did commodore do things on the cheap and only add controllers for machines shipped with drives (I'm assuming the controller lives on the main board itself)? Will the 1200 accept any size (capacity) drive? Or wasn't the OS / ROM code hard-drive aware and cheated by making the drive look like a big floppy (I'm sure there were systems which did this, but I can't remember if the amiga was one of them)? Presumably 2.5 drives are the preferred method - but there's nothing to stop 3.5" IDE drives being used with a suitable adpator (OK that's actually an IDe question - I think it's just the connectors that differ between them though, right?) On the hardware side of things, someone said the 1200's IDE controller is basically unbuffered I/O straight to the CPU (which sounds possible certainly with IDE) and so it's real easy to toast things - is that true? What are the options of networking a '1200 (ideally TCP/IP stack on the Amiga, using SLIP or something to a Unix box maybe? Are there things around that allow this, with NFS mounting of drives for data copying?) Can PC SVGA multisync monitors be used with the 1200, or won't the monitor sync to a low enough frequency for the Amiga (seem to remember that was the problem with the 500, not sure if the 1200 has any sort of 'fix' for this on the Amiga side though) Having seen how cheap 1200's are these days, and having a pile of spare IDE drives lying around (both 3.5 and 2.5) I'm quite keen to get a 1200 to put Deluxe Paint on - it's still far better than any art package I've seen on modern systems despite being ancient by modern software standards! I can't be bothered using my old A500 for this though - too slow and too painful without a hard disk... directions to an Amiga FAQ that may answer some or all of the above would be most useful too! :-) cheers!

Sure. Early germanium diodes are point-contact devices made using a small crystal of germanium. I've not tried it, but I imagine a modern Schottky diode would be a good replacement. Some of them have an even lower voltage drop than normal germanium diodes, so the set would be a little more sensitive. -- Pete Peter Turnbull Network Manager Dept. of Computer Science University of York

Looking For MC6800 Site

by univac＠earthlink.net

Can anyone point me to a good website about the Motorola 6800 (6800, not 68000)? I'm designing a simple computer around it, and need some info. Thanks, Owen

Speaking of the fastpath4 boxes, is anyone interested in two of them? I have no interest in them right now. Prefer trades for IBM stuff, primarily PS/2.

Well I'm pleased with myself :-)

by cmcmanis＠freegate.com

I recognized a CRT tube at the local surplus place (R@RE NEW IN BOX! :-) that looked like the CRT from a VT320 and I bought it ($2.14 including tax), took it home and opened up my worst VT320 (this is one I had already tweaked the internal "brightness control" so that I had enough raster to see it) and sure enough, same Phillips part number. So I carefully disassembled the VT320, removed the old tube, put in the replacement tube, and voila` a nice bright VT320 with no screen burn at all. Alas it was yet another amber tube, I really wish I could find some green tubes which I prefer. Anyway, yet another piece of classic equipment, brought back into peak operating efficiency. --Chuck

And I don't recall any transistors. I *think* it was isolated-chassis, but I also remember adding fairly high-voltage non-polar caps to the video input. About the only thing I can remember is that it was a wooden case with channel selector and ON/Volume (I think) on the top, and finished in tasteful dark green leatherette.

A silicon diode will require a stronger signal to overcome the .7 volt threshold. Since we've already violated the purist aspects by using a semiconductor diode, you could use a battery to apply a forward bias to the diode. In this model, the signal doesn't need to overcome the entire .7 volt forward bias voltage and makes a radio that is MUCH more sensitive.

D connector tirade (NeXT mono monitor cables?)

This has been bugging me for a while. NeXT mono monitor cables have a D connector with 19 pins at either end. They are (apparently) in pretty short supply relative to mono NeXT systems. Does anyone know the real designation for those connectors, and whether it's practical to think about building substitute cables? I'm still worried that this issue may become particularly relevant Sunday evening when Curt unloads his $1k stack of NeXT systems. - Mark

Even the A4000 didn't fix this compatibility with SVGA multisync monitors....for some reason only the A3000 did. Jeff

If you think so, find out about SNMP (Simple Network Management Protocol) and possibly RMON. If you have Windows, look for the SNMP service which is buried in one of the subdirectories on your CD; it includes "snmputil" which you can use to retrieve or set information (but beware if you install it on an Internet-accessible machine as it makes a lot of things available to remote enquirers and has a lot of security problems). If you have Linux, look on the net for UCD SNMP (which has some command line utilities) and SNMPY or SCOTTY. There's also gxsnmp but it's only in an early stage of development. For a bit of fun, take a look at Netcool (expensive!) or MRTG (free!). There's lots more, but that'll give you some idea. http://rak.isternet.sk/linux-netman/snmp.html is a reasonable place to start. > >> IOW it's just a glorified OFF switch. =) > > >Partitioning, is, yes.

Not many repeaters do, especially old ones, as it needs a fair amount of extra electronics. Basically it's done by a crossbar switch, which is inside one large ASIC in modern repeaters that provide it. The most common form of segmenting in hubs is in dual-speed (10/100baseT) hubs; what they really do is segment the ports into a 10baseT segment and a 100baseT segement, with a little store-and-forward switch in between. -- Pete Peter Turnbull Network Manager Dept. of Computer Science University of York

Mac haul and print server questions

by ethan_dicks＠yahoo.com

The March winds have been unsurpassed at depositing Macintosh parts at my feet. Last week, at my new job, a new co-worker gave me a pair of AAUI 10BaseT transceivers; the show at Dayton disgorged a Quadra 660AV; and the university surplus turned out to be a gold mine. For $5 each, I picked up a 15" Mac monitor, two LC IIIs, two IIsis, an external 170Mb disk, and an Apple external 80Mb disk. I got for free from the cable bin, some LocalTalk cables, three LocalTalk dongles, one PhoneNet dongle (w/terminator) and three data- center-grade AUI cables, including a DEC-branded one (perfect for my VAX8200) Most of these accessories I've been looking for with some intensity of late. In amongst the bits were Ethernet cards all around. I picked up the IIsis, not for themselves, but because ISTR that the IIsi PDS slot is compatible with the PDS slot on the SE/30. If so, then I can finally stick that SE/30 on my network without using up my one and only SCSI<->Ethernet dongle. A surprise in the lot was inside one of the LC IIIs - an Apple IIe card. It stood out because of the DB44? connector on the back, rather than the expected RJ-45. I have heard of the Apple IIe compatibility card, but where can I find a cable for this connector, which I presume is for attaching an external drive to? I haven't gotten home yet, so I have no idea if there is software on the Mac's drive to control it, but I hope there is. Finally, now that I have an abundance of Ethernet-capable Macs, I want to turn to a long-standing project - turning a Mac into an Ethernet<->LocalTalk print server. I don't care if I have to sacrifice one of my larger Macs and run a variety of UNIX, but what I want is to be able to print from other machines, UNIX, Windoze, Amiga, etc., over whatever protocol I can manage to universally support, and print to this HP Deskwriter 660 that is sitting here, lonely. Additionally, I could drive an HP LaserJet 4/ML over the LocalTalk port from the same print server. Are there any packages for the Mac that will let me share the printer with non-Apple-based machines? Is there something like CAP (Columbua AppleTalk Protocol?) for Windoze? (I've used it with Linux) I am not a Mac newbie, but my experience with Mac printers is limited to "plug it in, load a driver and go". I've never had to mess with them much, because they are, in my experience, fairly well behaved. I will go RTFM once I know where the FM is (and any software to go with it). -ethan __________________________________________________ Do You Yahoo!? Get email at your own domain with Yahoo!

Sparcstation prom passwords

by broth＠heathers.stdio.com

I found a really easy way to get past the prom passwords in the NVRAM in SUN sparcstations. I have tried it on a Sparc LX,IPX, and IPC and I really think it should work on any model. If there is a well known fix, disregard. After much searching the web on this, all I ever found was "replace NVRAM chip" I will post the procedure here if anyone is interested. Brian.

If it isn't, where can one possibly get it? /usr/sbin/snoop on my Solaris systems -- but it might be elsewhere on an older system, and it's not installed by default. Alternative is tcpdump, which uses a library called libpcap. The home page for both is http://ee.lbl.gov/ or http://www.tcpdump.org/ , and they can be downloaded from ftp://ftp.ee.lbl.gov/ You'll need a decent C compiler -- which probably means gcc, as Sun stopped providing a compiler with the OS a long time ago. > The printer manual has surfaced, but it only contains the information that > the Ethernet card was an add-on and had its own Installation and Configuration > Guide with it - which must be buried even deeper than the manual itself if > we were given it at all On most of the Ethernet-enabled printers I've come across (mostly HPs, Lexmarks, and Xeroxes) you can do the setup from the front panel -- sometimes tedious, but usually not too hard to understand. > I guess the remaining problem is really the IP address of the printer, as > the data transfer between the computers and the printer must be all right by > now: Whenever a ping or something else occurs on the network, the orange DATA > LED on the printer's back side blinks a few times (what should indicate it is > receiving the data). A reasonable assumption. Have you tried printing out status pages? Sometimes that will show you things like IP address, protocols enabled, that sort of thing.

The IDPROM isn't a PROM, it's an NVRAM chip. I don't recognise that part number, the usual IDPROM for a Sparcstation 1+ is 525-1109-xxx. The NVRAM is an unusually tall 24-pin device with a barcode on the top (usually), and I think the number you quoted is the boot EPROM, which is quite a different thing. You could replace the IDPROM with one from another 1+, or read the Sun NVRAM FAQ about reprogramming one, but you can't just use one from a different type of motherboard as the type code would be wrong. -- Pete Peter Turnbull Network Manager Dept. of Computer Science University of York
