The 64K words limit

From the "historical" point of view, 64K words matches the old-fashioned technology being employed. Most minis in the 60s and 70s came equipped with about 8K words, being 64K a costly luxury. It was using one of those minis (DEC DPD-11) that the UNIX operating system was invented.

From a realistic viewpoint, I'll be writing software in plain Assembly language for a long time. Even when I could envision the developing (or porting) of a full featured operating system in the far future, it is hard to imagine the need for more that 64K words of memory due the kind of software that Heritage/1 will be able to run in practice.

Lets imagine, however, that 64K proved limited at some point in the future. In that case, I will be happy then to accept the challenge to start developing solutions both in software and hardware.
