Ironically, you might have missed the best Apple days when it comes to hardware reliability.

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>

>Apple Computer Co. always impressed me as being >entirely too willing to compromise the quality of MY hardware/software, and >the security of my data, in favor of their profits. WOAH?!? That's just a shot from the dark... Apple is known for how good their quality IS... sure they had a few flops, but most of their hardware is built well, and built to last. And security? Um... compared to what? Windows? BWAA HAA HAA HAA HAA!!! -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>

Repaired PB 5300ce in my possession, serviced in '96, no problems other than tiny built-in speaker has died. Runs longer on its lithium cell than any laptop I've seen. I use it for a system console on the Prime; it's on 24x7x365. Most batteries get screwed by that. Not this one. Got a 500w halogen worklight too close for a while... plastic was too hot to touch and started warping where the LCD shell comes together on the top edge (top as in when the lid is up). No harm to LCD screen. rock-solid. don't make 'em like this anymore. -dq

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

by caprio＠dcms.com

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?

When I adjust the pincushion, the pincushion goes away >immediately, though I've not adjusted anything, and the image size goes back >to what it was, but it's dim again. 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

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. I the realm of radios (transceivers) I have several I've designed that far exceed commercial gear as I could specialize them. Generalizing on DIY/homebrewing is not good as exceptions do abound.
