[Coco] Lower case 6847 Q

[coco at yourdvd.net]

In assembly, I use the following to activate true lowercase:
	LDD	#$8A10
	STD	$95C8
	LDA	$FF22
	ORA	#$10
 	STA	$FF22
The first two instructions patch BASIC. The last three turn on true
lowercase.

This assumes the computer is in all-ram (64k) mode.

in BASIC:
10 REM RUN ROMRAM OR SIMILAR PROGRAM TO PUT YOUR COMPUTER IN ALLRAM MODE
BEFORE RUNNING THIS.
20 POKE &H95C8,&H8A
30 POKE &H95C9,&H10
40 A=PEEK(&HFF22)
50 A=A OR &H10
60 POKE &HFF22,A
70 PRINT "am i lowercase?"
