I've got two Western Design Center W65SC02s (14MHz
>6502s! Woohoo!) to play
with, plus a Synertek SY6502A (the 2MHz one), two W65SC22s (10MHz WDC 6502s)
and two Synertek 6522s (1MHz).
14 MHz? You're kidding! That's criminally fast!
2) Has anyone got a schematic for a fairly
half-decent 16-colour (or
better) video card that can be modified to work on a 6502? I've had a look
at the NASCOM schematics but I've heard Bad Things(tm) about the NASCOM
video system. Aparrently Gemini and a few others produced colour video cards
for the NASCOM. Anyone got schematics for these? Graphics would also be nice
(the NASCOM video system is text only).
Tony mentioned teletext chips a few days ago. Don't know if those perhaps are
only 8-colour, though. Tony?
BTW, I'd like to avoid obsolete components if
that's at all possible.
I've got a Hitachi HD6845 but if the 40-odd page datasheet is anything to go
by, it's a real dog to use... And it only works in monochrome. I have got a
MOS Tech 6568(?) VIC-II, the same one used in the UK Commodore 64. The PSU
for this C64 is fried, took out some of the support components with it.
The VIC is quite well-documented, and it would certainly be interesting to see
it in a non-C64, 14 MHz 6502 system. =)
