I was about to ask if anything else would be necessary to assure hardware
compatibility with the 5150. It looks like the MS-DOS support board is
what I
was thinking of. Does the RTC include a battery in
the package?
I don't see it elsewhere on the board. That might be a cause of trouble
later
on (see Sun workstations).

Hi Dave! Thanks! The S-100 MS-DOS Support Board uses a DS12887 RTC which
contains an internal battery.
They last about 10 years or so. Please a socket the chip and if it runs out
of backup power just replace it.
I suppose it would be easy enough to add a connector for an external
battery. Let's discuss with John.
We are open to requests on the design but if you have input we should
probably discuss it on N8VEM-S100 mailing list since it would be off-topic
here.
Thanks and have a nice day!
