I've been accumulating the damages from a recent thunderstorm. Wow!
Originally I thought
it was just a GFI breaker and the phones. But it turns out that a
computer got hit (just a PC),
and the cable box as well as a TV. I'm making a list (8 entries so far).
Thank God my bro-in-law
here in Maryland gave me a surge supressor that I put on my SWTPC. Makes
me think I need
more of those things.
Anyone else have such an event happen? Also, take this as a warning to
protect you most valuable
possessions. I intend to get a few more surge suppressors to protect
stuff. This is the one and only
time that this has happened to me, and I'm felling lucky.

Hi all.
I finally found some time to continue scanning doc.
So far I scanned (at 600 dpi) the following manuals.
Each chapter is a separate TIFF file.
- PDP-11/34 system user manual
- PDP-11/34 maintenance manual
- PDP-11/34A power system description
- KY11-LB SLU/RTC programmers console/interface
operation & maintenance manual
- DL11-W SLU/RTC operators manual
Also the following Field Maintenance Print Sets (FMPS)
and Engineering Drawings (ED) are scanned at 600 dpi.
They are broken into several parts, though the files
are still quite big.
- 11/03 Engineering Drawings
MP00049 & MP00050 KD11
MP00051 MMV11-A G653, H223
MP00052 EIS & FIS, backplane, power assy, H780
MP00055 DLV11
BA11-M, H9270-A, H780
- FMPS DD11-A
- ED DD11-D
- FMPS DRV11 MP00054 (M7941)
- FMPS LA38 MP00754
- FMPS LA8 MP00075
- FMPS LAX35-CL MP00714 (20 mA current loop), MP00738
- FMPS LAxx MP00248 serial interface
- FMPS MXV11-A MP00730 (M8047)
The list above is 300 Mb.
So still some 340 Mb to go to fill an other CD-ROM.
Next I will scan the 11/34 FP processor and the cache,
after that I will start on the 11/35 and core (MF11).
Anyway, is there interest in these high quality (I think)
scans?
happy holidays,
Henk.
Thanks to eBay and a couple of list members, I now have my Indy up and
running and on the 'net using my ISDN router as the gateway. I can also
ping my office network through the other router. I'm currently running
IRIX 6.5. It has a R4400SC 150mhz cpu, 192mb ram, a 24bit graphics
card, Granite kb, mouse and 20" Trinitron monitor, a 2gb hard drive and
an Indycam. I'm building an external SCSI box to house a DAT drive, the
CD-ROM, a CD-R drive and a 2gb option drive. Now I need to find a
Presenter, a Cosmo board, a 10/100 GIO ethernet card, the XZ graphics
board and floptical drive to have a fairly complete system. It looks
good sitting on my desk next to the NeXT TC slab.
Now for my next project, to get the Sparc Station 5's I bought the other
day up and running!
Just for everyone's information
About a year ago someone mention that DATA I/O had
taken down the all the files of family/pinout codes
for their old prom programmers. In response to a
recent request for information. I checked again and
it seems that most of them are back on their web site.
What I found by looking through the files:
Go to http://www.dataio.com/support/ftp.htm
This is DATA I/O's FTP site
Select "device lists"
Then select ",archive"
There is a file called "wallchrt.exe".
This is a self-extracting archive file. Run it in an empty directory.
After it has extracted it's files, click on "WC.BAT". Wallchart is a
menu driven DOS program that seems to have lists of supported devices
for most of their old programmers, along some "footnotes".
(w54_pgm.exe looks like it MAYBE a newer version of wallchrt.exe)
Family/pinout codes can be found in files like:
device lists\29_fpo.txt - 2900
device lists\,archive\s1000.txt - Series 1000
device lists\,archive\unipak.txt - Unipak
device lists\,archive\series22.txt - Series 22
device lists\,archive\logicpak.txt - Logicpak
etc.
Also look at
device lists\,archive\README
device lists\,archive\README old.html
device lists\,archive\README.html
for some more information on these files

Cool! How about letting us know what you think of Amiga OS 3.9 once you get
it loaded! I'm especially interested in the networking side of it. I don't
suppose you've got a graphics card or network card in the system?
Hmmm, I've now got some room under my main computer desk, so I could
potentially fit the A3000 I've got stuffed into a Tower case under there, or
de-tower it and set it up.
I'd like to get it back up and running, but the question always seems to be,
what am I going to do with it.

Yes, but the schmitt-triggered one has a different problem -- it's too
slow! It's a long time ago, and the articles and my notes are buried near
the bottom of a heap of other stuff, but I seem to remember that the
frequency response of the schmitt device was quite low. I didn't use it in
the end; I built a custom amplifier with the front end in the pen tube.

Indeed. If you're not careful, the detector that can "see" the spot on a
"dark" screen gets dazzled by a lit pixel, or fooled if you tilt the pen so
ambient light leaks past the tip. I gave it up.

It works by doing what Chuck described (flashing a frame or a line) or as
Megan described (using a target). I've seen it done both ways. I've never
seen a commercial lightpen do what I did, using the low light from "black"
(which isn't quite black) to trigger a sensitive detector -- a detector
that sensitive is just too prone to being swamped by ambient light, I
discovered. It was fine when the pen was pressed against the tube, but
goes haywire when lifted away. I fitted a touch switch to mine to prevent
that, but it still took the amplifier a moment to settle.

Dick,
7 dollars is worth getting that Mac for parts, 7 dollars plus
shipping on the parts stripped from that Mac is what I can use.
Quadra use full 68040, this 650 is blazing 33MHz.
Cheers,
Wizard

Hi,
I bought a VT420 from a neighborhood garage sale ($5) that
turned out not to work. Turn it on and I saw nothing happening.
Only heared a faint "fip ... fip ... fip ..." kind of sound,
you know that one "fip" when a screen comes on, just a little
softer and repeated about 1 per second and no screen came on.
Opened the box and powered on, the kathode in the tube didn't
seem to glow. More inspection turned out that what seems like
a ceramic capacitor was exploded or fried, all black and
crummy, impossible for me to identify its specs. Can someone
help me out with a schematics or databook or something?
Again the terminal is DEC VT420
the blown-up capacitor is C621.
What kind of collateral damage do I have to expect? I mean,
does a fried capacitor normaly cut short? Here are some
hints:
- That C621 is in close proximity to C617, another sizeable
capacitor. However there are no marks left on that one after
cleaning the explosion site :-)
- A diode D603 is also in that neighborhood, doesn't look
bad, but I didn't test it yet.
- I do see suspicious brown-coloration in an area farther off
around D607 and R649. I wouldn't be surprized if R649 was
fried.
- R650 is in next to R649 but looks fine to me, though I
didn't test it. It's always a problem to test components
while in the circuit, don't know what I should expect.
I appreciate any help.
thanks,
-Gunther
