16 bits arithmetic:
	signed 16bits math and unsigned boolean operation
16 bits addressing:
	65536 word, all word are 16bits
every ops is 16bits
	0000:7FFF immediate into stack

no graphic memory , just stream IO
two stack are separated from main memory (dedicated memory for each)

32 ops (3 of them fit in a word):
	and or not xor
	add sub shl shr 
	inc dec mul div 
	mod abs neg
	jmp 
	jz jnz js jns
	load save
	in out		IO stream
	...

freakin 32 char interface
0123456789ABCDEFGHIJKLMNOPQRST_ UVWXYZ
alternate
0123456789ABCD FGH JKLMN PQR  UVWXY_
they are 5 bits and 3 of them fit in a word

massive storage work with io port, rev, fwd, seek
