The Integral PC provides a built in HP-IB interface and two
I/O ports. A bus expander may be connected to each I/O
port to provide space for additional interface or memory
modules. At the time this guide was printed, the following
interface and memory modules were available for the Integral
PC:
• HP 82919A Serial Interface
• HP 82920A Current Loop Interface
• HP 82921A 300/1200 BPS Modem
• HP 82923A GPIO Interface
• HP 82925A 256K Memory Module
• HP 82927 A 512K Memory Module
For
information on how to program either the HP-IB interface
or the plug-in interfaces, refer to the HP-UX Technical BASIC
I/0 Programming Guide.
The use of external memory modules in the bus expander will
increase program execution times by as much as 30 percent. If
program execution time is critical to your application, try
configuring the system with all memory modules located in
the mainframe ports.
