|Finally passed this along to someone I hope make better use of it than I. I just didn't have the time, space or supporting doc/software to work with it.
I picked this up with a bunch of other HP
equipment and some Apple equipment for $50. It has these board plugged
into slots in the rear; HP BASIC Rom Card, 98256A 48L Rev D, Eventide
WKBP-4 Rev C and 98626A RS232 Rev C. Also when I power it up it tells me
it needs memory above a certain location, I need to go back and check
the message. If anyone has any doc or software for these I'd like to
hear from you.
