Reconnected up the scandoubler on de1. This required sharing the pokey mixer to fix in m4k on de1. Also some work on using better pal/ntsc settings on de1 (not yet working)
178 09/23/2014 10:11 PM markw

Fixes for 5200 support. Now working:-)
173 08/26/2014 10:23 PM markw

Making a start on 5200 support. GTIA needs to expose full consol output for this. So far just removed chips from custom top level and made address decoder adjustments.
172 08/25/2014 10:25 PM markw

Added reset to noise filter (helps for sim), fixed inversion on poly5.
171 08/25/2014 10:03 PM markw

Remove inversion
167 08/23/2014 11:48 PM markw

Match more closely to schematic - delay/inversion
166 08/23/2014 11:43 PM markw

noise delay between channels. Apply force break to two tone.
164 08/21/2014 12:07 AM markw

It is important when we sample and when we toggle. Fixes "clarinet".
147 07/29/2014 11:51 PM markw

Changes for Aeon lite - notably 1MB ram support and ise build warnings fixed
146 07/29/2014 10:59 PM markw

Merged aeon lite 1MB memory support
