some guy is selling two 8bits isa cards. one is a serial + parallel controller. but the second one, seems to be a parallel (printer) + "something ".
that something I think is video. but I´ve been unable to identify what kind.
the picture have bad quality (the one Im posting is already a little enhanced, anything I´ve done to improve it dont give clearer text). so I can not be sure on the IC identity, besides is from Yamaha. I think is V636J or V838J or something like that. the date seems to be 1987.
does anyone recognize it?
the two chips in sockets to its left pretty sure are vram, and the top left is the EPROM.
Im looking for 8bit or 16bit or 8bit friendly ISA VGA cards , and this one may be useful. but I think is CGA or EGA.
