Notes about Disk System
- Ports 44 to 47 are for standard connection to FD2793.
- Port 48 is used for drive/side/density select on write, and intrq/drq on read.
intrq and drq are OR'd together, then gated to bit 7 of the data bus whenever
port 48 is activated on read. There are no interrupts used.
Tests of old keyboard. Start mbeeic.
1. Load ASTEROIDS PLUS, stay in attract mode, hold down spacebar,
it should only fire bullets. If it sometimes starts turning,
thrusting or using the shield, then there is a problem.
2. Load SCAVENGER and make sure it doesn't go to the next level
until you find the Exit.
3. At the Basic prompt, type in EDASM press enter. At the memory size
prompt press enter. Now, make sure the keyboard works properly.

Tests of keyboard. Start mbeeic. Rewritten by Robbbert
1. Load ASTEROIDS PLUS, stay in attract mode, hold down spacebar,
it should only fire bullets. If it sometimes starts turning,
thrusting or using the shield, then there is a problem.
2. Load SCAVENGER and make sure it doesn't go to the next level
until you find the Exit.
3. At the Basic prompt, type in EDASM press enter. At the memory size
prompt press enter. Now, make sure the keyboard works properly.
TODO:
1. mbeeppc keyboard response is quite slow. You need to hold each
key until it responds. It works much better if you overclock the cpu.
