No, it is NOT easy to access the TPDD2 from an NEC Starlet usinf Mbasic, I've tried. The problem is that all the RS232 routines are in ROM, and can only be accessed by switching out the ram, therefor Mbasic. I have tried to obtain a programmer's guide for the NEC, to no avail, it has been orphaned by NEC. Eventually I will crack the I/O address for banking in and out the ROMs, and can then create a dissassembly, and THEN maybe figure a way to access the RS232 port. It will take a lot of work though. It would be nice if someone that had a Basic ROM for the NEC, complete with documentation, that would make any tech details available??? Tim Mihulka
