Yes, and by coincidence it has exactly the interfaces and peripherals
corresponding to the 9825's ROMs.

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).

I don't have that book. While I'm not especially interested in
microprocessors generally, these little boards remind me of the first
machine I owned myself -- although at 512 bytes, this one has *twice* as
much memory. *Luxury*!
