Subj: REPLY TO MSG #6475 (NEC LAPTOP)

If I understand you correctly the 8201 and 8300 have the same kind of bus
connector as found on the M100 or perhaps on the M102/200.  Because I'm working
on software that resides in Rampacs (rather than in RAM) and Rampacs can
migrate from the bus connector of one laptop (e.g., a Model 200) to a different
model laptop (e.g., a Model 102), the software must tell which laptop model is
at hand. With NEC laptops having the same bus connector as Tandy laptops, then
I need a small address range for generic use that's common for all models and
zero fingerprints for the models. To date I'm OK for M100/102, M200 models.
Since your last message, I'm OK for zero fingerprint of 8201/8300 and I have
enough info to find a small address range for generic use across models
M100/102, M200, and 8201/8300. So I'll assume the NEC laptops have the same I/O
signal pin-out of the system bus connector as for the Tandy laptops -- thus a
NEC will load (the initial fingerpring test) from a Rampac (into address range
suitable for Tandy and for NEC) and conduct further loading based on zero
fingerprints.

You might tell me if what's called the "Kyotronic 85" laptop is similar to the
NEC laptops.  To date I have no zero fingerprint for it, although I do have
enough RAM map info to know where it shares common generic use addresses with
other laptops.
