Source for DEC TC01 (and similar) bulbs?

2021-12-04 Thread Josh Dersch via cctalk
Anyone sitting on a pile of these or know where to find some?  These were
originally Dialco 507-3917 or Drake 11-507 based on what was installed in
mine.  24V, 40mA, white.

A total of 23 bulbs were dead on my TC01's panel.  I've installed a pile of
electrically/physically compatible bulbs that I happened to have, but
they're yellow/orange and have a different visual design (the yellow lens
sticks out 1/8" or so, whereas the orginals were flush).  I'm honestly fine
with using them but it'd be nice to have something that looks original.

And a small progress update:  Found that the IOT decode for READ STATUS B
wasn't working, which is done on the W103 decoder at E/F19.  With that
resolved the diagnostics are behaving much more rationally.  This took me
much too long to trace down, but I learned a lot about how the controller
works and found a fun (but ultimately harmless) bug in the Basic Exerciser
diagnostic that threw me off for a couple of days...

The Search Scope loop diagnostic shows block numbers going by in both
directions so a lot of the drive and controller are working, but there's
some glitchiness in bits 2, 5, 8, and 11 of the data so I need to trace
that down; I hope it's not the tape head.

I picked up a Kunkin KP184 this last year, and it does nicely for testing those 
brick regulators and the power control boards in isolation (a bit more 
convenient than the old light bulb or power resistor approach.)

Some of the large electrolytics in those bricks will likely have dried out.  I 
disassemble and “reform" these with a bench supply and current limiting 
resistor on any of these bricks I have not yet personally serviced (Yes, I know 
the reforming thing is controversial for some.  I think its safe to say it at 
least doesn’t hurt anything :-)

Check the big bridge rectifiers carefully; I’ve seen a few of those cracked or 
toasted.

It’s also been my experience that beyond the bricks that are dead or fail at 
the start, some smaller fraction will also let go after the first few hours of 
continuous operation.  The don’t tend to fail with fireworks — you’ll generally 
get a slowly increasing whiff of magic smoke so generally plenty of time to 
shut things down.

The operation indicator bulbs on these seem almost always dead.  You can sub 
CM7381 for the +5V regulators, and OL-6003BP for the -15V.

Last, if you have H742 supplies on your 11/45, be sure to check the small 
muffin fan above the power control board. It is quite common for parts of the 
internal wiring harness to rub up against these and stall them out, eventually 
leading to a fried controller board.

Good luck!  Good winter time project :-)

As far as my wife, she is active in two local LEGO user groups and was

sometimes not the best idea if one wants to remain an enthusiastic

A very, very long time ago, when dinosaurs still roamed the earth (or at least 
the computer rooms) there was a guy on usenet who called himself "Altair Bob" 
and offered to buy Altair computers.  This was back when they weren't worth all 
that much (mid to late 1980s).  He must have bought a dozen or so (as I 
remember).  Does anybody know who he really was and what became of his (what 
I'm assuming was a) collection?

Just idle curiosity brought on by a recent discussion of collections being 
destroyed by widows.

pdp8/L restoration time, part 1: switches

2021-12-04 Thread Chris Zach via cctalk
I've decided it's time to fix my second pdp8/L. First one is missing (I 
think it's at the bottom of the closet) so I'll work on this one for awhile.


First problem: Testing the lamps and switches. If the switches don't 
work or the lamps are out it's not going to be easy to troubleshoot. 
Currently I'm missing 5 of the plastic switches, and I have 2-3 switches 
with a broken pivot.


Since I was going to need new plastic switch covers I fired up the 3d 
printer, downloaded the STL file for making them (thank you for putting 
that up!) and ran off a few for testing. It helps a lot to set the 
bridge angle value to 60% or so, that allows a nice solid bridge for the 
two "teeth" that engage the rocker switch. Also don't bother with PLA: 
The plastic pivots are too weak and break pretty quickly. Use PETG, 
which requires higher heat (240 instead of 200 at the head and 70 
instead of 60 at the base) but it is more than strong enough for the 
pivots to go in without issues.


Testing the switches I found that one of the data/address switches was 
reading high ohmage (20) when closed in the down direction and two of 
the data entry (spring loaded) switches were intermittent. Sprayed in a 
bit of Deoxit, and they now switch cleanly and without bounce. That 
would probably have driven me crazy if I tried to test with that.


Next step: Check out the power supply.

Woke lego?? What lego has been at fore front of this idea of being open to
all for a long time so woke hah no being there as a community of growing
and creativity yes...

What's wrong with bringing out a set to celebrate these women who in many
cases worked in toxic male bs environments...  let's celebrate.  Not
complain plus there's now a univac in an official lego set!!

See, if it had been presented like that, it would likely have not elicited the 
same response.

It’s sad, but I understand the reason why they are doing it.  Lego has always 
been a bit progressive - even going as far as in commercials that girls can 
play with legos too.

Unfortunately, the ones that throw the term ‘woke’ around like that tend to 
have pretty strong feelings about a “woman’s place in society”.

Using the term ‘woke’ these days is a great way to render any point you are 
trying to make moot.  Great way to make people people not take you seriously.

He may as well have just come out and said, “It triggers me and I don’t like 
having to acknowledge that women exist in the field of computer history.”

How dare LEGO(tm) remind me that women exist? This is clearly communism.
