Hello all,
Just picked up a HP 1000e series, it came loaded with 640k in
memory but
not a single I/O card.
I've been reading up on what might be a good set up for a terminal and
paper tape I/O (to hook an emulator to) but there seems to be a
dizzying
number of serial and drive boards that I'm a bit lost on it all.
Any suggestions as to what might be a good set up to run a terminal
and
have some way to push programs to it? I've been reading Terry
Newton's site
and his hp IPL/OS looks very interesting, especially with the USB
drive
emulator he's put together. Also, any sources for for boards other
than
eBay?
The 12531D or C are a 'straightforward' choice for an RS-232/20mA
serial interface.
The 12597 is the basic 8-bit parallel interface if you had, for
example, a parallel paper-tape reader.
Long list of interfaces, categorised and with brief descriptions, if
you haven't run across it already:

My experience is with the earlier 2116C (I wrote a bootstrap
downloader & driver for the 12531D).
The 12531D was common for the earlier machines and (I believe) should
work with the 2113, but I don't know whether it may have been
superseded by a newer serial interface design for the console for
later models.
