IS THERE a more comprehensive portable analyzer? (other than a modified

IS THERE a more comprehensive portable analyzer?
(other than a modified
Compaq lunchbox computer)
Hmmm... It seems to me that this is a low-level analyser, looking at
distortion (unequal lengths of marks/spaces) and things like that. It
doesn't seem to be able to grab the data as characters and display them
later.
Somewhere I ahve a battery-powered breakout box that will do some of waht
that can do, inclduing send test messages, display distortion, etc. My
Trend 1/4 is probanly a better distordion meter. Bot of those are RS232
only, yours seems to do current loop too. Then there's my TDMS5, a wonder
valved (but jsut about portable) device to send test signals with
controlable distortion and display it distortion of the incoming signal.
At a higher level (character rather than signals), I use a 'Black Box'
unit I was given recently. It's a Z180-absed thing with a Z8530 serial
chip. YEs, it handles synchronous as well as async data, EBCDIC as well
as SCII (and baudot, but for some insane reason the slwoest baud rate is
75 :-().
If that;s not enough, I have a Ferret. That thing is portable
(attache-case style) and incorporates a breakout box, RS232, curent loop
and paralell interfaces, a hex keypad, a strip printer, a cassette
interface (!) and an EPROM programemr (!!). You can do all sort of
things with that, includign RS232 to current lop conversion with
different abud rates o ntejh 2 interfces, capture an print data on a
serial line, send test messages, program EPROMs. writye and run Z80
programs, etc, etc, etc.

OK, which clssic computer prodiuct used a 36 pin Microribbon connector to
carry RS232 (and RS366) signals?

I am goign to guess (without watching it)_ that is is a clip from the UK
television programme 'Spitting Image' from aobut 25 years ago.
I was at universtiy when that was firt boradcst, and hat a repution for
being a 'geek' or whatever. Another student made some crack about wanting
an 'RS232 Interface Lead' at which point I pulled one out of my pocket.
The reaction from the otehr hackers present was priceless...
