I'd like to counter the idea that "pizza box" == "any desktop style enclosure". An Indigo2 is not a pizza box. The Tandy 1000 is not a pizza box. I'd argue that the Sun Ultra 1 isn't really a pizza box. Indy, sure.

The SPARCstation 1 really does resemble a pizza box in many ways. It was a novel package for a computer system, by 1989 standards.

The PGC wasn't much of a solution for anything. Too expensive, too few pixels, way, way, WAY too slow. I'd read all that before, but was still surprised the first time I actually saw one working by just... how... slow... it was. It didn't make any sense, not even in '85.

The CD-ROM drive doesn't need to be recognized by the Mac OS (except just as a normal SCSI target) in order to use it for Ivory BOL. I used an old Chinon.

I'll give you a copy of mine if you ping me sometime this weekend while you're in town?

I see keyboards on ebay much more frequently than the machines themselves. This is what it looks like: http://www.ebay.com/itm/141494569306

There's not much in the way of documentation. Here's the project notes from my IP2020. http://typewritten.org/Projects/Intergraph/h0jhvb.html

That'll work. The cable I made has 5 BNC on the other end, not a VGA connector like the project notes.

There was a type 7007 model N40 manufactured for IBM by Tadpole, with a 50 MHz 601 in it. I think the pictured unit is this model.

Probably not very. This is the most information on the Hillcrest I was able to find, which strongly suggests the Acer was built around the 7011-220 logic board, which uses an RSC processor (apparently a reduced-capability, single-chip implementation of POWER1) at 33 MHz. The article mentions only the US BLM as committed customer (to implement an automated cadaster system).

This is the kind of behavior you get when the PSU is going into overcurrent protection because it's plugged into a short. If they repaired the PSU, presumably they tested it was working before they sent it back. That suggests to me the problem is somewhere else in the machine.

If it still shuts down with the graphics and drives removed, I would start by looking at the -12v rails on the mainboard. A shorted tantalum capacitor can hide here since the whole -12v load doesn't normally draw enough current to cause a catastrophic breakdown of the capacitor (explosion/fire) like you would get on the +5 or +12v rails, but will still cause the PSU to shut down. Measure the resistance between the -12v PSU pins on the mainboard and ground. The load should be less than an amp (>12 ohms). If it's anything under 10 ohms, there's likely a problem. I'm willing to bet you'll find it's under 1 ohm (e.g. a full short).

I use words that I like.

bucket, mapplethorpe, godthaab, vanburen, malibu-barbie, shrdlu, angstrom, kaiju, fratricide, diesel... they're not always meant to be flattering. an amiga 3000 got named "laugh-track", and a boat anchor Proliant got named "epsilon-minus".

and so on.

I'm not sure what makes you think the "y" is backwards...?

Yikes. I hadn't seen that before; that is indeed awful.

I have a deskside RE2 I'm getting ready to sell. PM me.

You should be able to just install MPTN &c. off the Connect disc. IIRC the Connect install does a totally normal OS/2 install, then starts a second installer to apply the Connect code. Connect is just a bundle of regular OS/2 plus a couple extra products which could also be ordered separately and applied to a non-Connect OS/2.

It's meant to take a 166 MHz 604e. I don't know what else could be made to fit.

I have a big pile of spare SolidImpact boards for I2. PM me if you're interested in one.

I agree. Less common, and less desirable. It's just about half as fast as the 2. I don't know about "less capable" though.

I am missing the GE board for my ISA IrisVision. I made that guy a pretty decent offer several weeks ago, which he refused. Just sayin'.

pretty sure an nfs export can't implicitly cross a filesystem boundary. this is a security measure.

Weren't 68Ks (020? 030? 040?) a bit slow ?

What is it you think they needed to be "fast" to do, exactly? It doesn't take much horsepower to run a 1-bit X server. Or a color one, for that matter.

What a totally bogus comparison. Never mind that the A/UX machine is also doing all the unix stuff as well as running the X server, and could be "slow" for all kinds of reasons (MacX vs. the dedicated server, speed of the video board, etc.), you might as well rag on A/UX for not supporting X11R5 or having a compositing window manager either.

I'm not arguing that the xp217c isn't a better choice today (not least being almost five years newer tech during a time of very busy progress), I'm arguing that a 68k is perfectly capable of running a totally serviceable standalone X terminal. Lots of people were happily using scavenged Sun 3/50s as X terminals as late as 1996, and the primary limitation on those was never the 16 MHz 68020 (it was the 4 MB RAM limit). As you noted, the advent of the WWW changed what people expected from an X terminal (for about three instants before it made them completely obsolete). The old stuff is still just as capable of doing the old jobs as it ever was.

That's BS. These SMT electrolytics leak in everything. They leak in Sony CD-ROM drives. They leak in Canon and Panasonic floppy disk drives. They leak in IBM PS/2 DBA hard drives. The similarly sized miniature through-hole electrolytics used in all kinds of drives leak like a bugger too.

If you look at Suns, NeXTs, SGIs of the same vintage... you'll find they haven't used any SMT electrolytics anywhere. That's why they "don't leak".

SiliconClassics wrote: So is it possible to resurrect dead optical drives by recapping them? I've seen tons of CD-ROM and DVD-ROM drives fail inexplicably over the years and always assumed it was the lens mechanism wearing out, but if it's just a capacitor problem then it should be easily repairable, yes?

Well... The Sony mechanisms as used in the Apple CD150 and CD300 drives surely respond very well to this treatment. I'd hesitate to suggest that any (or even most) arbitrary drive failure(s) could be cured this way. The tray-loaded Toshiba drives are more prone to mechanical failure IME. And the older Sony mechanism used in the Apple CD SC has an open optical pickup and I've seen several "failures" there caused simply by dirty optics.

For example.

If "minifs" contains a miniroot filesystem, which you have written to partition 1, I rate it unlikely that the name of the file within that miniroot filesystem which contains the kernel you are meant to boot is also "minifs". it may be called 'munix' though. have a look at minifs in a hex editor, you'll be able to find the root directory and filenames pretty easily.
