Notes For V3.8

The makefile now works for Linux and most Unix's. Howevr, for Solaris
and MacOS, you must first export the OSTYPE environment variable:

> export OSTYPE
> make

Otherwise, you will get build errors.

1.2 GRI

- Added support for the GRI-99 processor.

1.3 HP2100

- Added support for the BACI terminal interface.
- Added support for RTE OS/VMA/EMA, SIGNAL, VIS firmware extensions.

1.4 Nova

- Added support for 64KW memory (implemented in third-party CPU's).

1.5 PDP-11

- Added support for DC11, RC11, KE11A, KG11A.
- Added modem control support for DL11.
- Added ASCII character support for all 8b devices.
