microprocessors generally, these little boards remind me of the first

much memory. *Luxury*!

Yes, the interfaces are the same but the ROMs are
very different. Do
you have a 9845?
Yes, and by coincidence it has exactly the interfaces and peripherals
corresponding to the 9825's ROMs.
Does the 9825 have the
pull-out system ROM in the side or only a slotted cover? If it has the ROM
then it's a 9825 A, if it has the slotted cover then it's a B model.
It does have the side ROM drawer (and is marked 9825A), though it has the
full-travel keyboard (which IMHO is *horrible* -- nothing like the
contactless keys on the 9845).
Also got a 6800
evaluation board, MEK6800D2, with hex keypad & LED display.
That's cool. The 6800 evaluation boards are rare. That module is
described in Motorola's MicroProcesor Applications Manual for the 6800. I
HIGHLY recommend that book if you're interested in the 6800s.
