1640B is a very different thing - I should've added that it's basically a
glorified RS232 breakout box, and nothing like a 'logic analyzer'.
It definitely won't connect to peripherals itself - there's a very obvious lack of
buttons and menus to configure something like that.
I suspect that the GPIB functionality will be about managing what is in the programmable
buffers that it can send out in response to some input on the serial link it is
monitoring. But how :-)

Hi all,
I have a HP 1640B that I'm trying to get to work. However I can't find any
information about it, and while the machine itself it straightforward enough (and I
remember enough from when I was using it in my first dayjob) I can not find anything about
how to use the GPIB interface that it has.
The reason I'm interested is, we've finally managed to add GPIB support to the
PDP2011-MINC fpga implementation, and I'd like to test against a different target than
the relatively modern Philips/Fluke counter I'm now using. And the 1640B is the only
other GPIB instrument I have...
The HP doesn't seem to know the ID? command (that causes an error message on the
screen). It does respond to a newline (the standard is-this-listener-present test that the
MINC code implements), so at least something is working.
Does anyone here have any docs on the HP 1640B? It'd be very helpful at least to know
which GPIB commands are implemented.
thanks in advance!
Sytse
I have an HP1631D Logic Analyzer and it has an HPIB (GPIB) Port too, but
as far as I know it is only used to connect a special HP Floppy Disc Drive
with HPIB bus, the HP9122 for example, others exist, even a hard drive.
It is used to load and store measurements and loading disassemblers.
Maybe it can handle a printer too.
I've got such an HP9122 later and tested it with the Analyzer...works.
(BTW: does someone have Z80 an 6809 Disassemblers for the 1631D?)
Regards,
Holm
