Hi Tony
It certainly looks to be a good version of BASIC.
1) What softwware do people recomend? HP BASIC
looks reasonable,
actually, it does at least support named procedures with formal
parameters. Anything else reocmended?
HP BASIC is quick to put together and powerful. The documentation is good and available (as you've seen, or got). I think
the documentation was one of
HP's strong points with these machines.
Well, the hardware docuemtnation of the machines themselves is not to my
liking, but the docs I've seen on the DIO cards is good. And the
programming manuals are certainly clear and seem to be complete.
HP used to produce excellent documentation, that much is certain.
HP Pascal gives you the speed, but you'll
definitely need more memory ...
How much memory? My 9817 has 2 megabytes.
2) How much RAM do I reasonably need. If I pulled
one of the 256K cards
from the 9816 so I could add a DIO I/O card, would the machine still be
useful?
My programming career started with HP9816s' with only the 256K on-board RAM;
that was using Basic 2 originally, then Basic 3. And we got by - the
company didn't want to spend any more than it had too! That was in civil
engineering & construction where we were able to put together costing,
critical path planning, and some envelope & pre-stress design software.
Whilst it is certainly constraining, so you'll probably be ok with one
add-on RAM card for a lot of things. Later on, I got involved with a land
surveying package, which besides being able to do a multitude of cadastral
calculations, included a fairly comprehensive CAD facility. That definitely
needed more RAM, and was standardised with a 1MB add-on card. For all above
software, the only IO we did was RS232 for HPGL plotting, so only needed the
built-in port. 4) Anything
elase I need, or should keep an active lookout for?
Probably 913x/915x spare hard drives, unless you're able to get the drives
at http://www.bering.com/main.htm from a 9122 floppy drive only.
