Forgot to mention a major advantage of putting RAM chips into the
cartrige slot:  If you POKE &HFFD7,0 any accesses to them will
run at doubled clock speed!  Copy your speed-critical machine code
routines up there and let 'er rip!  However, to use the CTS- enable,
you must bypass a series resistor and cut out a shunt capacitor
in this signal (FCC emission control, no doubt).  And see my earlier
article about 64K Cocos.  mike k
