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.
