These guys are great!
I emailed them asking if the new TAF ColorDMD required a TAF Gold eprom.
Randy Perlow himself emailed back the next day saying they have tested it with LX-3, L-7 and H-4. They all work, but H-4 is reccommended as it contains additional animations.
My good mate Anthony will sort out an eprom upgrade to H-4 for me as the extra graphics are very cool.
I'm on the B.A. waiting list and can't wait to get mine!
