Title: 40 column VDC
Post by: Blacklord on December 09, 2007, 08:38 AM
Ever wanted to put your VDC into 40 column mode ?

100 CLR:FAST:FOR T=2816 TO 2851:READ A$:POKE T,DEC(A$):NEXT
110 SYS 2816
120 SCNCLR:PRINT "40 COLUMN VDC DEMO"
140 DATA A0,00,B9, 16, 0B, C8, BE, 16, 0B, C8, 20, CC, CD, C0, 0E, D0
150 DATA F1, A9, 27, 85, E7, 60, 3F, 00, 28, 01, 35, 02, 49, 03, 89, 16
160 DATA 57, 19, 28, 1B

Yes! I want!

My intend (for tomorrow) was to re-read all my C128 mags to search for this (well known) 40 column trick.
Your post saves me a lot of time. Thanks!

I tried to use the 40 Column mode for Hires - yes I did but failed.
I want to copy a VIC Hires to the VDC and I don't want to double the pixels (the VDC should do the job).

Is there any trick to do this?
Has anybody tried this too?
