/***************************************************************************
PHUNSY (Philipse Universal System)
2010-11-04 Skeleton driver.
2012-05-24 Cassette added.
2014-01-13 Quickload added.
http://www.tubedata.info/phunsy/index.html
Baud Rate ~ 6000 baud
W command to save data, eg 800-8FFW
R command to read data, eg 1100R to load the file at 1100,
or R to load the file where it came from.
The tape must already be playing the leader when you press the Enter
key, or it errors immediately.
Rom banking (in U bank):
0U: RAM
1U: MDCR program
2U: Disassembler
3U: Label handler
