It has been a while since I've looked at my PCjr, but IIRC, the IR
receiver is built into the chassis of the PCjr. Thus, there is nothing to
"connect" to the PC, and thus, it would be improbable that you could use
the PCjr keyboard wirelessly with a modern PC.

Hi All,
How many types of front panel keyboard were used with the 2113 E-series CPU?
I have one in front of me that has two ribbon cables that run from the
keyboard PCB to the CPU PCB (one from the top edge of the keyboard PCB one
>from the bottom edge) but I seem to remember having seen other 2113 CPU's
where the keybaord PCB is smaller and a single cable runs from the bottom
edge of the keyboard to the CPU PCB.
What I'm trying to do is find a 'short' front panel to replace the
'embedded' keybaord of a 5420 Signal Analyser and turn it back into an mini
E-series CPU.
I had assumed that I would be able to unbolt the top of a 2113 front panel
and use just the keyboard portion of the assembly but the PCB behind the
keyboard that I have turns out to be too tall! Is there is shorter one
available.
Can anyone shed any light on this one?
Cheers
Peter Brown

There are a number of diagnostic DVD's intended to setup your home
theater. I have an older one called "Avia" which has a fairly wide
range of video and audio tests - It does color bars and numerous other
video tests, and comes with colored filters that you use to look at the
screen during some of the color tests.

Dave

Back in May of 2003 you indicated that you had a box of Maxell digital
cassette tapes.
Do you still have these? Are you interested in selling them?
I could pay by PayPal or check.
Please let me know.

Talk about short, 3 or 4 minutes I think. The talked about the early years
and ended with the B5000. You really can't summarize Burroughs in that short of
time.
They did recommend The Computer Museum in San Diego.
I captured the segment in VHS Video but have no way of posting it.

Yea, did not make my day. We do telecom testings. Most everything
is -48VDC battery powered. So I managed to accident get the battery
power across the equipment's frame ground and it then put the voltage
on the receive pins and lord knows what else.

I found the two drivers chips (9636). They had a different number but they
cross-listed to the
9636s. There was another 8 pin chip between the two and the traces look
like they might run to it.
So its probably the receiver. However it has a number different than the
9637. I of course
forgot to write it down. So is life. Anyway might be a mute point for now
as I remembered I
have another VT320 in the shed with a bad tube.
Anyway, Digikey lists the 9637 as available so I might try fixing the board
as a spare. Thanks
for the help. Of I will also put sockets in.

Thanks Bruce. Many of the DEC terminals don't use the 1488 and 1489 for
the receiver and driver. This one doesn't. But
thanks for the quick input.
