Deinterlacer
A Video Deinterlacer Board Based On The Amber Chip From The A3000 Motherboard
Doubles All 15.75 KHz Screen Modes To 31.5 KHz
HD15 VGA Connector
Enable / Disable Switch
Full Overscan Support
Dual Port Static RAM Bank – New Video And Cleaned Video Are Read In And Outputted Simultaneously
Although Originally Designed For The A2000 It Works In The A4000
Some Modifications Are Needed To Fit The Board Securely Into The A4000 Video Slot
The Board Gets Confused By Some Of The Doubled AGA Modes, And Rather Passing Them Through It Tries To Double Them To 55 KHz Or Above – On These Modes The Board Has To Be Disabled With The Switch
It Samples 12 Bits For Each Colour, On The A4000 The Upper 12 Bits Of The 24 Bit AGA Information, So AGA Screen Modes With More Than 32 Colours Or HAM6 Will Have The Colours Quantized To A Certain Degree
Compatible With Some Genlocks
