I've ordered some CF-IDE adapters (99p ea. from China) to make life a little easier; even if a mod. or two is needed I'm mostly connecting to a 0.1" header rather than directly to the CF socket.

Call me old-fashioned, but the direction I think I'm heading in is the "405-line slide-projector"; probably using a Z80 to read frames (slowly) from CF into what amounts to dual-port RAM, where it'll be read entirely by hardware (likely to be TTL/CMOS) into a DAC.

Think of something like an EPROM-based test card generator, with a ROMulator in place of the EPROM(s) and a Z80-based CF card reader periodically transferring new stills into it.

Unless someone wants to try to convince me that I really should get into CPLD/FPGA/etc. and I might enjoy it...
