/***************************************************************************
Z1013 driver by Miodrag Milanovic
22/04/2009 Preliminary driver.
The 8x4 keyboard contains letters A-W, enter, cursor right/left, space, and
4 shift keys.
S1 - X-Z, numbers
S2 - a-w
S3 - x-z, punctuation
S4 - control keys
Control Keys:
G - Graphics
A - Alpha
T - clear screen
U - enter
P - cursor left
Q - cursor right
Monitor commands (debug)
R - registers
B - breakpoint
E - execute
G - resume after breakpoint
N - single-step
Monitor commands (general)
H - switch to hex keyboard (H to Q become 0 to 9)
A - switch back to normal alpha keyboard
C - Compare memory blocks
D - Dump memory
F - Find bytes in memory
T - Copy memory block
M - Modify bytes (; to exit)
I - reboot
J - Jump to address
K - Fill memory (K by itself fills all of memory)
L - Load Cassette
S - Save Cassette
W - window (example: W EF00 EFFF)
Due to no input checking, misuse of commands can crash the system.
