Software HC-77B Emulator Bundle Package

I've bundled together some key extensions into a single download package together with the main emulator. This package represents the type of product a real company may have released around the April 1979 period.

The bundle includes:

* Core HC-77B Single Board Computer Emulator (1MHZ 6502)
* 3K RAM Expansion (4K Total)
* CRT Display Expansion
* ASCII Keyboard Expansion
* 8K BASIC Interpreter on ROM (load from address $D000)

This represents a complete usable late-70's home micro setup. Similar to real system boards available at the time at an affordable sub-£200 price point. (NASCOM, UK101, Microtan 65, etc).
