Summary: Final posting - thanks to all

Many thanks to all who responded, especially to those who pointed me to ICL
chips, and those who pointed out that the 1488 will work fine from +/-5 V.
I got the entire hardware and software for the project working this weekend
using the Apple +5 supply and my bench -5 supply.  watmath!jsgray suggested
the ICL7660CPA chip which eats +5 and puts out -5 and is available at Radio
Shack.  I am going there later tonight to try to snarf up one - and that
should just about complete the project...
