ST-225 = 2 platters, 4 heads, one head per surface. ??
Fuji Eagle = 6 platters, 20 heads, two data heads per non-outer surface, plus one servo head on an outer surface.
I think the confusion may be "outer half of a surface" vs an "outer surface".

So. 75 new mails in the cctalk folder since I checked my mail this morning:
- Sometimes people on eBay are not honest. Sometimes people overreact
to this. Sometimes people overreact to the overreaction.
- Your college degree doesn't mean much. Or it means something.
Maybe. Regardless, a BS is a foot in the door / waste of time / stupid
requirement / very useful / a floor wax / a dessert topping / a
communist plot. (Choose only 2.)
- Sometimes hiring practices are suboptimal or unfair. Especially in
the corporate world. This is because HR departments are full of
stupid-heads who refuse to acknowledge your greatness.
- No one intelligent (er, "truly hard core") uses or buys Microsoft
products, EVER. (EVER!)
- Mail readers exist. Some are better than others, possibly. Sometimes
you can even use them to do stupid things!
- Nothing made in the last 30 years has improved Tony's life one iota.
(Not even self-adhesive stamps?! But they're so handy!)
- Hey, did you hear that HR people / managers are stupid?
- Thunderbird sucks / no it's ok!
- Some people have axes to grind with other people.
- Did you know that if you replace "soft" with "shit" in the name of a
certain large software company, it makes people take you seriously?
(It's true!)
- Some nonsense about some old HP computer thing. What the hell is
*that* discussion doing here?
Can we... maybe discuss old computers again? Pleeeeeeeze?
Here, I'll start: Anyone know if the original TRS-80 Model I power
brick suffers from the same failure modes as those old C64/VIC-20 power
bricks? Any repair options? I've got an old one that seems to be
working OK for now, just wondering if it'll stay that way...

Hi,
Has anybody experience and instructions how to replace aging and breaking plastic parts.
I would prefer replacement with metal parts not to repeat the problem later.
The problem is in parts like sledges etc. but not in running mechanics.
Any tools, methods etc. recommendations are welcome.
Unfortunately my experience is more on the electronics side.
I would see the replacement work as a nice hobby but I need the skills and tools first.

In July of 1983 Tandy announced the "Tandy Videotex and Office
Information System" that ran under Xenix. It was an early attempt at a
hypertext system. It used dialup lines and was hosted on Tandy Model 16b
(and later 6000) computers.
An 8 port and 16 port multiplexor (that's how they spelled it) were
announced. I don't know if either ever shipped.
There is some information available in the July 25, 1983 issue of
InfoWorld. There is also an article in "TRS-80 Microcomputer News" V5,I
11 (#54 ).
I used to run one of these for a local company (that I still work for).
Does anyone have the manuals or software from one of these systems? I
still have the hardware (not the mux, just the 16b and hard drive).

Perhaps somebody has dealt with a similar issue...
I have two venerable Toshiba 24-pin dot matrix printers dating from the mid-1980s, a P1340 and a P341. They are working just fine ? evidently, Toshiba intended these beasts to endure. When I got a new laptop with 64-bit Windows 7 installed, I went through some headaches networking to a Win98 PC that interfaces to the printers, but the data path is working and stable.
The problems is that Windows 7 (XP, Vista) hasn?t a clue on how to format for the older printers. I can?t find anyone with a driver that works on the 64-bit Windows 7, and I get absolutely no response when I make enquiries of Toshiba. In fact, as far as I can tell, Toshiba has purged any admission that they once manufactured these beasts from their Websites. Drivers intended for newer Toshiba products don?t produce usable output.
I bought my P1340 new for $800 (a significant price for that time and my personal budget), and I am determined to keep using it as long as it works (finding ribbons has not been difficult, indicating that there?s still others working out there). My OSI Superboard, Kaypro 2 and NorthStar Horizon are all perfectly comfortable with these printers, so it is annoying the new stuff is finding it so difficult.
Has anyone either (1) made/encountered/adapted a printer driver that would allow Windows 7 to format output for the Toshibas, or (2) found a method of convincing Windows 7 to use printer drivers written for Win98/95/3.1? I really am trying to save myself from having to learn how to write printer drivers for Windows 7... or loading Linux only to find similar issues...

> Hey, that looks like a Fujitsu M2444AC magtape drive on that system. If you don't want that, would you be willing to slide it in my direction?
Not just one, but two!
M2444 is pretty sweet. Oftentimes there is a proprietary interface but behind it (Well, beside it in the card cage) is chained the two-50-pin-Pertec-formatted interface.
And of course a common option at least when these were used on Suns was SCSI-to-Pertec-Formatted bridge.

Got a line on a local Sperry Univac machine, model # unknown but
appears to be a 1980s-era UNIX system. Only pics so far are here:

I believe it is at least two racks containing CPU, boards (probably
lots of serial) and tape drive. System is located near Lisle, IL
(western suburbs of Chicago.)
If anyone is seriously interested and can arrange a pickup, contact me
and I will put you in touch with the owner. Time, as always in these
cases, is short.

Yep...just talked to the owner, he says there were about 30 terminals
with it. They are all gone, along with all manuals, tapes, etc :(
I am making arrangements for pickup. Stay tuned later in the week for
updates...
