IBM AT power supply case/cooling question

by fernande＠internet1.net

I'm using the case from an IBM AT to build a socket 7 Linux machine. The AT wasn't complete, and the case is a little rusty on it's hood, so it wasn't a good example to restore to original. My question is this..... can I safely leave the PS cover off? If I add a few of the factory screws the PS case/chassis is still quite solid, it just does have the cover on the top, or by the drives. Basically, it removes two out of six sides. I'd want to do this for a bit more cooling, since the fan would have less obstruction. Plus, I think it looks lind of cool too :-) Would I have problems with EMF emmisions effecting the computer's operations? The main case cover would be installed.... would I have other EMF troubles, if I leave the top of the PS off? Chad Fernandez Michigan, USA

I was just curious what's out there. Secondly, for a 5-6 staton LAN, including servers, it makes little sense to have lots of switching/routing hardware and a complex topology.

Funny networking protocol, I think over top of RS-422 or the like. Sometimes they tunnel it over ethernet too.

My LAN uses Netbeui and IPX/SPX. There's got to be a way ... If you are doing file/print sharing, I would use AppleTalk if possible. The key is can any of the servers you are running speak appletalk. (NT4, Win2k, Netware...). AppleTalk isn't the most secure protocol as far as packet sniffing is concerned... but very few internet routers will route it, so it is a fairly safe bet that the traffic will not go beyond your lan (as your internet router box will most likely ignore the packets and not pass them along). Appletalk has the added advantage of just working. It finds its own node address, and sniffs out the network by itself. Pretty much turn it on, and it works. It doesn't get much easier than AppleTalk. Downside is, it tends to be a bit chatty, and it isn't real fast (usually about 4Mb/s on a 10Mb network is the best you will get. AppleTalk of TCP/IP is much faster, but then you run the same risks you do for any TCP/IP traffic) >Is there a "slick" way to exploit hardware that's already in the Performa >630CD? Eh... not really. There are software things you can run to route Localtalk (built in to all macs since the 512kE IIRC, definitly since the Plus) to Ethernet... but somewhere you will still need the hardware connection to go to Ethernet. But you should be able to lay your hands on an LC Ethernet card for the 630 with ease, and fairly cheap. Worst case, if you don't find one local, let me know, I can probably turn up a spare and let you have it for a song (read: probably free + shipping depending on how fast you need it, my time schedule, and how many I have kicking around) -chris <http://www.mythtech.net>

It does have what looks like a real filesystem, but I doubt the illusion goes further than skin-deep :-) It is one of the GT's most interesting features, but since it works just fine with Epyx FastLoad, I don't use it often. More to the point, the GT's in-ROM fast loader doesn't work with any other drive but a GT, and most utility cartridges have some kind of DOS wedge, so the files aren't called for much now.

PDP11 M8190 console + DIP switches / FPA

by jkunz＠unixag-kl.fh-kl.de

Hi. I am looking for the console bulkhead pinout and the DIP switch description of the M8190 / KDJ11-B PDP11 QBus CPU module. I had a look at the micronotes and googled around, but found nothing. Also: The board seams to be revision C1 (stamped on the handle). Does this mean I can not add a FPA? I am a bit confused because there is only "KDJ11-B" written on the board and micronote 39 lists the "KDJ11-BC" as FPA incompatible. field-guide.txt contains no "KDJ11-BC" and lists only the "KDJ11-B 11/84 CPU" UniBus CPU as FPA incompatible. -- tsch??, Jochen Homepage: http://www.unixag-kl.fh-kl.de/~jkunz/

There have been some pretty impressive workstations. Add that to the fact that some people consider a one-year-old machine "old." I won't argue that peesee hardware hasn't advanced. it's literally mind-blowing what they've done with it, given the origins of the thing.

All? I haven't checked top500 recently, but there were certainly a few non-clusters in the top 20 last time I looked. My trouble with clusters is that they're not "tightly coupled" enough to make them very interesting to me, generally. Sure, they'll solve problems, but again, I/O is the bottleneck. > Another example, look at www.ltsp.org, they are netbooting old > retired PC's used a diskless xterminals and hanging up to 200 > of them off a modern machine that the apps run on. I've considered doing something like that just for fun, and it's interesting, but as far as being a "cluster," I'm not sure it would qualify in my book. :) Or did you mean it as an example of something else? > It saves them bucks, and a machine not bloated down > to a 486 with winblows can hump a good load these days.

It's not so much the size of the tree that bothers me in general with Linux, but the size of the finished kernel. I do still use it occasionally on <on topic> hardware, and it really annoyed me when I had to start using the bzImage target for make ;) I don't think it's in the drivers, either, but in the kernel somewhere, that it's gotten larger. There could be a good reason for it, but I'd like to see some of the stuff optionally removed so that my kernels can go back to being a few hundred kbytes uncompressed.

Nuvolink made a box, SCSI interfaced Ethernet, 10-base-2 and AUI. The Quadra 700 was a slight modification to the Mac IIci. The IIci didn't have Ethernet; the Q700 did. The IIci was a 1990 machine. Q700 was probably late '91 or early '92. Not sure therefore what you mean by "old". May have been e-net boards that clamped down on the 68k chip like the hard drive upgrades and the 1st Radius FP display, but once SCSI was in place, you had that. But shortly thereafter you have e-nat on (almost) every Mac. -dq

For Localtalk Macs, you have a few choices. 1) Some models, like the SE/30, had internal slots in which an Ethernet interface could be installed. These are, however, rare and somewhat pricey. 2) There are ethernet adapters available that hang off the SCSI port. These are quite proprietary, and can be hard to find software for. 3) You can use a Mac running Localtalk Gateway software for a router. However, that Mac must have a localtalk and ethernet interface. 4) You can buy standalone boxes like the Shiva Fastpath that handle routing Localtalk to Ethertalk. These generally work rather well, and can be found cheaply on Ebay. I use a Fastpath 5 for my Mac network, and it's not failed me. Locating and configuring the software is the biggest hurdle; I've compiled an archive of information at http://dbz.icequake.net/oldskool/fastpath/ . -- Ryan Underwood, <nemesis at icequake.net>, icq=10317253

EtherTalk is AppleTalk running on top of Ethernet. -- tim lindner tlindner(a)ix.netcom.com "Life. Don't talk to me about life." - Marvin, the android

I'm sure not aiming to start another flame war :-) >My position is based on what I saw in '81-'82 with then ][ and ][+, where 10 >complete data losses per hour were the rule rather than the exception. Ironically, you might have missed the best Apple days when it comes to hardware reliability. (I can't say for sure, but I have been hearing the rumors growing that QC on the new flat panel iMac isn't all that great, and I know QC on the iceBook isn't less than wonderful) >One thing that I've wondered is how one gets an old MAC to talk on the >Ethernet when it's a mixed environment with Netware and Windows NT >servers.

Most Macs, since sometime in the early 90's have come with ethernet on board. The exceptions were the home targeted models (like the Performa series), where ethernet was an optional add on. Every mac since the G3 comes with ethernet standard (basically, with the death of the performa line came the death of optional ethernet... it was just included with everything from then on out) Every mac with an expansion slot can have ethernet added. Every mac with at least SCSI can have ethernet added. If you have a pre-scsi mac (128-512), then it gets a touch harder, but then, if you have one of those, and don't know what you can and can't do with it... I'll take it >from you for cost of shipping. That pretty much means, every mac from the Plus on can support ethernet. For your Performa 630, you can add either an LC PDS ethernet card, or a Comm Slot 1 ethernet card. The LC card will probably be the easier to find. Beyond that, you just have protocol issues. The Mac doesn't natively use anything other than AppleTalk for file and print sharing (up thru OS 9... OS X is a whole different ballgame). If you are in a network that supports AppleTalk, great, everything will work fine (NT 4 and 2k support it, as well as I believe later versions of Netware, and there are some *nix packages out there as well). If you can't get AppleTalk supported, then you will have to add things to the Mac to access the servers. There are 3rd party apps out there to enable the Mac to speak to a number of different systems. If this is something you want to do, I will be happy to discuss it with you, but it is going to get off topic really fast, so we are better off taking it off list. -chris <http://www.mythtech.net>

Nickel Metal Hydroxide.... no Lithium Ion batteried PB 5300's are in public circulation to the best of my knowledge (and I don't think any made it past internal testing and early seeding... they exploded during charging). If you really have a LiON batteried 5300 lets talk... what do you want for it? But I agree on the battery life... it just seemed like it never died, and never lost its life-span. I could go a whole evening on a charge easily. Way better life span then my 1400 (which even with a new battery was lucky to get 1.5hrs, now I get 30-45 minutes on a charge) >No harm to LCD screen. rock-solid. don't make 'em like this >anymore. The only recurring problem with the 5300 AFTER it has been put thru the repair extension program, is the screen cable tends to fray and break. Other than that, a repaired 5300 is a very good reliable unit. I actually miss the size (why do all computer makers assume everyone wants a huge screen? I want a portable computer... give me a 10.4" 800x600 screen, thin and light.... I don't want these 15" wide screen designs) -chris <http://www.mythtech.net>

IIRC, the extension program on the 5300 is good for 8 years from the date the 5300 was discontinued. Unfortunatly, if the tech manual for the 1710AV is to be believed, the repair program only lasted 5 months for it (August of 98 to Dec 31 98). -chris <http://www.mythtech.net>

>Since it was cheap, I snagged an AppleVision monitor/speaker combo today. >What systems will support it? I figure I'll find one eventually. > >It's only a small risk at $3.95. If it is one with the AppleVision plug (HDI-45, this kind of rectangular plug with lots of pins in it), then only the 6100, 7100 and 8100 support it directly IIRC. However, there is an adaptor out there to break out the cable to its RGB plug, mic, speaker, and ADB, so you can plug it into any of the other Macs. Also, the last series of AV monitors weren't true AppleVision monitors, and only had the standard RGB plug, if you have one of those, than any color mac EXCEPT the 6100, 7100, or 8100 should support it (those 3 will support it IF they have the optional RGB card installed, or if you have the HDI-45 to RGB pigtail). -chris <http://www.mythtech.net>

ARK files

I picked up a bunch of CPM archives from CPMUG. The files end with the ARK file extension. I've tried the unark16.exe I picked up from the oak.oakland.edu site but I can't seem to get them to unpack. What MS-DOS command works on these archives or do I need to fetch a CP/M version and run under a CP/M emulator?

Doesn't really match any of the repair notes in the tech manual. Although there is a comment about CRT Arcing, and to turn off the unit, unplug the power cord and ADB cable from the monitor, wait 10 seconds, hook it all back up, and power it up. Problem should be gone.... but like I said, it isn't exactly the same thing as you are describing, so that might not do squat for you. Rather it sounds more like the brightness control might be dying. Maybe a bad cap or something (I'm not an EE, so I defer to someone with more knowledge in these things than me). -chris <http://www.mythtech.net>

The ZX81 projects which I am aware of all have one thing in common: they maintain the "flavor" of the original machine. This includes Sinclair BASIC, the screen font, and the rest of the ROM. Beyond that, it's wide open. If you come to our meeting next March (Germany), you'll see what I mean. How about it? The entire weekend, with meals and room, is only US$50. Glen 0/0

I just try not to associate with them. :) (The guy sitting across the room from me is writing some firmware for the project we're working on. A $2000 commercial 8051 C compiler (for Windows of course, the land of commercial software) just crashed because a function in the code it was compiling wasn't prototyped. If this weren't commercial bullshit, I'd have the source code, and I'd have fixed the bug in ten or fifteen minutes. But noooooo, that bug will be there for at least the next year. Some people just like commercial crap...I will never figure out why.) But there's a pattern with the Windows folks...they're often people who tend to do what they're "supposed" to do, and you're "supposed" to use a PC and run Windows on it, so that's what they do. The decision was made for them and they won't question it.

I'd think you'd either need a PC serial card that uses a USART instead of a UART, or a convert of some kind... but I don't know how the converter would supply synch... The Data General One notebook used the Intel 8251a USART for serial I/O; it through me for a loop because writing an interrupt handler for it is quite different from its 8250-based stablemates. But it wouldn't be too hard to kludge up a design for a single-port 8251a-based serial card... -Douglas Hurst Quebbeman (DougQ at ixnayamspayIgLou.com) [Call me "Doug"] Surgically excise the pig-latin from my e-mail address in order to reply "The large print giveth, and the small print taketh away." -Tom Waits

HP 9000/300 wanted

by vp＠mcs.drexel.edu

Hi, I'd like to experiment with OpenBSD on the HP 300 platform (mainly because these machines have both HP-IB interfaces and Ethernet interfaces). My intention is to make either an HP-IB to Ethernet gateway or at the very least write software enabling the HP 300 to emulate a CS-80 disk drive. If anybody has hardware that they are willing to sell, advice or links, I'd very grateful. Thanks **vp

From: Andy Holt <andyh(a)andyh-rayleigh.freeserve.co.uk> >I'll agree - but perhaps the main reason is that modern components are >almost impossible for the home builder ... and only the odd few (Tony? :-) Impossible? How? >want to spend lots of time and a fair bit of money to build something that >is usually less capable than a less expensive commercial product. There are two good reasons to DIY. One is for personal understanding and in that case practical is often not the point. Two is something specialized that a commercial peice that may be expensive or a poor compromize. I happen to build, RF, AF and digital and the economicas is that I have a very deep junkbox and parts supply to exhaust doing it.
