MessageHi Charles,I'd looked at PC104 boards a few years ago, but they were very expensive. If they are now becoming reasonable, that will be very intreresting. There is a version of BPQ for the Kantronics Data Engine which was used for quite a few remote nodes, but I don't know if it is still made. It wasn't cheap, either!73,John-----Original Message-----

Subject: [BPQ32] Re: DOS BPQ question
Thank you for the information, John!
I am trying to run BPQ in an embedded PC that will be running with no
monitor or keyboard, and boots up from a compact flash memory card. (
No moving or rotating parts )
The CF cards only tolerate so many writes, so I'm trying to avoid
that. The system is running under ROMDOS, a special DOS for embedded
PC104 form embedded computers are starting to appear on the
surplus/salvage market now at reasonable prices. They handle
vibration and temperature extremes well, have built-in watchdog timer
setups, and my 1996 vintage 133Mhz PS is only 5.75" x 8". It has four
RS-232 ports. - It will fit into the case from a dead MFJ 1270c.
It cost me about 25 bucks with the shipping. - Plus odd and ends for
development, connectors, a floppy drive to set it up with, etc...
When I'm finished tweaking the software, I'll disconnect the floppy
drive, keyboard and video - and will have a stand-alone 4-port BPQ
switch with no moving or rotating parts.
You can see the data sheet for the computer in a PDF file at:
ftp://ftp.emacinc. com/m-5890. pdf
I think that hams will have an easier time getting these smaller
computers into tower shacks, and they will hold up better on the job.
They are reliable enough to put BPQ into remote tower sites ( also
baloons, aircraft, etc. ) with some confidence.
Do a seach for "PC104", "embedded computer", "industrial
computer", "touchscreen computer", or "tablet computer" at eBay to
see these computers, some as small as 3.5" square by 1" thick!
