Hi, All,
Last week, I intercepted a 1970s Remex paper tape reader from a CNC
mill that was on its way to the scrappers. It resembles this one:
http://juliepalooza.8m.com/sl/remex.htm
I wanted to look at Steve Loboyko's code for his PIC serial adapter
and my attempt to download his link to his source was denied by his
ISP (due to the .asm extension). I wrote him at the address in the
GIF file he embedded in the page and my message bounced.
Does anyone have a current address for Steve Loboyko or happen to have
already downloaded his file remex.asm and could send it to me?
My plan is to examine the code, look for pitfalls, and see what it
would take to implement a similar scheme on an AVR chip since that's
what I have in abundance. It looks like a fairly simple handshake and
perhaps a bitwise data inversion then byte-wise serial transmission,
but I'd rather peek over someone's shoulder and see what they did,
given the chance.
Thanks,
-ethan

I certainly never was an Apple employee unlike others here.
It's interesting that Apple was away from Jobs from 1985 till 1996 and how this overlaps some of the dates others write, or I have implied in the past.
The 1985 to 1996 period certainly had a lot of solid incremental advances in the Mac. The PowerBook and System 7 certainly blew away anything available on a PC-clone at the time. But at the same time there were NeXT's popping up in offices around me too.... :-)

I see an 8-pin IC that is labeled LT 324 0425. It is at the right of
the memory on the motherboard and DIMs. On mine it it is silkscreened
D54 next to the IC.,

I've just got hold of a pair of PDP-11/35s that have 110V power supplies.
What is the collectives view on the best way of running these in the UK?
Is it safe to use a step down transformer (one of these for example:
http://www.ebay.co.uk/itm/3-3-KVA-SITE-TRANSFORMER-110-VOLT-110V-UK-SUPPLY-…)
or can I change the setup of the PSU to work from 220V?
Many thanks,
Toby

I've taken apart HDA's from crashed Eagles, with no hope of ever putting back together.
The heads are parked in the landing zones on the disk.
An Eagle is a little more complicated than a "typlcal" drive in that each surface has two heads - one covers the inner half, the other covers the outer half. I don't think this head arrangement is unique to the Eagle but it's not all that common.
At least one of the bearings (the bottom one) is in fact out of the HDA isn't it? On the top center of the HDA there's some sort of cover plate and I bet the top bearing is underneath it. Some might count that as "inside the HDA" but I count it as "on the outside and secured by a cover plate".
Not that I've ever done a bearing replacement on an HDA quite like this. On removable pack drives, sure (RL01/02, RK05, etc) but obviously the pack was out :-).
I would think you could locate a working HDA without a lot of difficulty.
Since this thread has gone completely off at a tangent, how about this:
Shouldn't the sentence
"They were an HP9866 printer, an HP71 and an HP82165 GPIO unit, and an
home-made interface"
be
"They were an HP9866 printer, an HP71 and an HP82165 GPIO unit, and *a*
home-made interface "
and similarly
"a 'Oxford comma' "
should be
"*an* 'Oxford comma' "
?
(since "HP" is pronounced "aitch-pee" (beginning with a vowel sound) and
"home-made" begins with a consonant sound).
Seriously though, I agree with Tony that sometimes minute details of
punctuation, quoting etc can be extremely significant. I spent four
years writing installation instructions for Unix software for Ericsson,
and during the review of every document, such details were always taken
extremely seriously, since it was intended that the reader of the
document should be able to reproduce every command exactly as intended,
otherwise the installation would fail, or be done incorrectly. Obviously
a Unix command line is very sensitive to dots, spaces, upper/lower case etc.
Another aspect which I think is important is that documentation which
contains spelling errors, bad grammar, bad translations etc reflects
badly on a product which may be excellent otherwise. If you can't be
bothered to produce correctly spelt, grammatically correct
documentation, what is to say that the product itself is any better?

Does anyone know about how many amps a G3 CRT iMac draws? More specifically,
I am talking about a 600MHz G3 model with Airport.

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...

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.
Tim.
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:
https://picasaweb.google.com/102190732096693814506/SperryUnivacRack
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...

As no one jumped in regarding my query, I thought I would venture out
along and try the tapping-along-the-seam technique previously
described and see if I could break into the dead Apple //c power
brick.
The tapping technique worked very nicely, although I had to apply
leverage with a screwdriver hammered into the seam to really crack the
two halves apart.
The scene of desolation inside revealed why it is dead-dead-dead, see
pictures here:

The smell is interesting too, it was nicely bottled up inside the
sealed PSU until I opened it...

Why do some people feel the need to be so self-righteous about products
that they
don't use? You don't like Apple products because of attributes of a
product that
hasn't shipped in almost a decade? How close-minded is that?
FWIW, I use that accessible unix shell under MacOS X to do my job as a
Solaris
kernel developer. Most of the machines that I use for work (and their
consoles
and service processors) are network accessible and I have no problem
debugging
kernel bugs and developing new Solaris features from my MacBook.
I don't buy your claim that Apple's portable devices (I presume that you
mean iOS
devices like iPod touch, iPhone and iPad because my Mac laptops are
portable)
"don't have anything that makes them useful for difficult tasks" because
they don't
have a shell. They are devices where the primary input method is touch
gestures.
"Boy, my TV (or set-top box) is useless because it doesn't have a
shell." "Why
didn't put a shell interface on this microwave? Worthless!"
I am an iOS app developer in my spare time. There are plenty of apps that do
difficult things. And iOS devices even have consoles and crash dumps if
you are
into that.
