Cool. Thanks for looking into the glitching issue.

On another note, I was having some trouble getting a printout from applesoft basic using the ssc and pr#1.

I can get it to output to a file, but the high bit on each byte seems to be set. A quick "tr '\200-\377' '\000-\177' " will strip the high bit from the output file but I was wondering if that's normal.

./mame64 apple2e -sl1 ssc -sl1:ssc:ssc_rs232 printer -printout outputfile.bin

and making sure that the printer and the ssc are using the same bps of 9600 in the Dip Switches and Machine Configuration menus

and then PR#1 and PRINT "HELLO" and PR#0

cat outputfile.bin | hexdump -C
00000000 8d 8a dd d0 d2 c9 ce d4 a0 a2 c8 c5 cc cc cf a2 |................|
00000010 8d 8a c8 c5 cc cc cf 8d 8a 8d 8a dd d0 d2 a3 b0 |................|

cat outputfile.bin | tr '\200-\377' '\000-\177' | hexdump -C
00000000 0d 0a 5d 50 52 49 4e 54 20 22 48 45 4c 4c 4f 22 |..]PRINT "HELLO"|

cat outputfile.bin | tr '\200-\377' '\000-\177'
