I haven't followed this thread, but at least at one time (circa 1995) there was an outfit near or in Philly that would cut the neck off of yer crt and presumably meld a new face (?) to it. Sounds like fun. You work the buzzsaw and I'll be in the other room checking on your medical coverage.
Does anyone here know where I could obtain a front panel frame for a
pdp11/70?

I've updated the p112 and zsdos pdf files to fix some stupid errors that I
never noticed. I also widened the text area. They're at

I'd like to get a pdp 11/70 front panel with frame. Would anyone here
take a Northstar Horizon in trade?

I've just been handed a small DEC badged unit, which I think is a terminal. It appears to have been made by Termiflex.
It is a handheld unit with a two line LED display, a 4x5 keypad, three unmarked buttons on one side, and a wheel device on the other.
It has a 25 way D type and a 3 pole AMP connector.
Does anyone know anything about it?
Jim.

That is a good list of some of the newer stuff. It obviously misses
out on much of the pre-1972 hardware, but it's a good start to
understand DEC's patterns.

Some of the smoke came out of my Osborne 1 this weekend. It doesn't
appear to have been fatal, as it was still functioning when I cut the
power. I'm giving the CRT some time to fully discharge before I open
it up, probably next weekend. It was probably a failing capacitor,
although it didn't explode, it merely got really warm over a period of
hours. But since there are some similar machines that I haven't
recently used, this question came to mind.
I've used the variac technique to reform capacitors, but thus far
haven't done this on a machine that contains a CRT because I don't
know what the reduced voltage is going to do to the CRT. The next
machine to power up on my list is a Compucolor II. Dare I power it at
15 volts for a few days before starting the slow ramp up to 115? Or
do I need to go in and detach the CRT circuitry before I try anything
like that.?
Hi,
Since noone else seems to have sent this to the list yet, I thought I would send a snippet and a link for those who might be interested in this.
Snippet:
NEW YORK, April 20: The world's number two software company, Oracle
Corporation, today agreed to buy hardware provider Sun Microsystems Inc
for $7.4 billion, or $9.50 per share, in cash, pushing the software
company into high-end computing system.
?We expect this acquisition to be accretive to Oracles earnings by at
least 15 cents on a non-GAAP?basis in the first full year after
closing. The business will contribute over $1.5 billion to Oracles
non-GAAP?operating profit in the first year, increasing to over $2
billion in the second year,? Oracle president Ms Safra?Catz?said in a
statement.

To All:
Just in case anyone was interested, here are the schematics that I found
for the Intercept Jr. and two of its accessory boards that were done
about 1975 or 1976. Your's truly drew all three of these on the drawing
board with pencil and straightedge. They were then turned into
publishable versions by a graphic artist. The two boards plus a third
one which had a number "devices" on it for lab demos made up the initial
Intercept Jr. product set. This was used to support the original
education classes that were based around this design.
Still looking for listings of the micro-interpreter. This was the
software that made use of the special keyboard and was embedded in the
mask-programmed IM6312 ROM.
You can see that the serial interface on the PIEART was arranged to
support either an RS-232C interface or the old-fashioned 20ma current
loop for communication with an ASR-33 Teletype.
On the RAM module, the board held a set of two AA batteries to provide
battery back-up on the RAM memory. It may be hard to believe but I do
seem to remember that Intersil actually patented the little circuit in
the upper right hand corner that prevented these batteries from being
back-biased when the regular power was on and kicked them in gracefully
when that power was lost.

Jeff Little
