Substitute for the µPD10(C) / TM4103

Here is a means of constructing a replacement for the µPD10C from standard CMOS. Note the pin numbers presented here are for the µPD10C. Pin numbers for the µPD10 and TM4103 are different.

This design was originally produced for the purpose of replacing a defective µPD10 in a Toshiba BC-1212.
