> Also, I'd like to see an "UltraCart" that contains all the known Ultimax games in one ;-) The Multimax cart is still on my 'to be completed' list. :-) I have a working prototype on a breadboard circuit that uses a 6-way resetable latch to control the upper 5 address lines of a 1mb eprom, which is 31 ultimax images plus the menu system. The setting of the latch is gated using one of the i/o lines on the 64 cartridge port which, on the max is the /exram line. I completed the menu system which seems to work to I just need to fabricate some pcb's which, as I've never done it before, is kind of where I ground to a halt in the spring. Now winter is setting in, i'd like to pick it up again. Anyone interested in co-operating to get it finished? cheers, Rob On 18/10/2013 19:14, Steve Gray wrote: > That's great!
