Subject: Re: Navtel 9460 Protocol Analyzer info?
From: "Jay West" <jwest at classiccmp.org>
Someday I'll pick up a "datascope" (aka
serial protocol analyzer) cheap. I
did a lot of serial communications programming in a prior life, and
absolutely lived with a datascope. Not sure of the brand, but I remember is
was blue. No keyboard in the real sense, but a data entry pad on the front.
It was the most incredibly useful thing... you could program it to watch for
a particular sequence of ascii characters, then start capturing data. One
button would flip the display between ascii/ebcdic, hex, binary.. and it had
a dual display mode where it showed transmit on top of the line and receive
on the bottom of the line. It was a godsend. It had a breakout box built
into it, could buffer to floppy, etc. It could also do sync & async.
I happen to have a Atlantic Research Inc, serial datascope. It contains
several boards [std bus z80, rom/ram card, CRT5027 based crt controller Card]
however no manual. Someday I'll track down at least a schematic and fix
the CRT. The boards say T-bar on them so the instument may even be from
another company with the ACI label. It would be fun to get it operational.
