Allan My guess...with the new MegaCart+, Bob should be able to: 1.) find a cure for cancer 2.) develop Skynet and the processor chip for the Terminator T-800 3.) fix the ObamaCare website 4.) create the first cold fusion reactor...providing free energy to all of the world ...or, perhaps, he will decide to just code some more insane games for us all!!!! 1 Link to comment Share on other sites More sharing options...
+Propane13 Posted December 16, 2013 Share Posted December 16, 2013 Looks great! Question-- for "Bankswitch + RAM/EPROM" Is there a potential for having something with "memory" that can be written to? Back in the day, this would have been a battery-backed SRAM, but nowadays, there's gotta be something you can write to that is electrically updatable without requiring a battery. Is that a possibility? Basically, it'd be a place you could store a local high score table or saved-games. Regards, -John 1 Link to comment Share on other sites More sharing options...

A nice eeprom scratchpad for RPG use. You know: shop keeper inventories, dropped item locations and whatnot. Link to comment Share on other sites More sharing options...

It would be possible to design such a board, but it would be a lot more limited in terms of ROM size. EDIT: Besides, my Chinese manufacturer just got back to me with a price for the newly submitted design. This will be my last contribution for a while, I am now around $1000.00 into 7800 board designs and selling a couple repros here and there isn't gonna get me that money back any time soon.

+Allan Posted December 16, 2013 Share Posted December 16, 2013 What's the largest amount of RAM a 7800 cart can have and can you bank-switch RAM like you can ROM? Allan Link to comment Share on other sites More sharing options...
CPUWIZ Posted December 16, 2013 Author Share Posted December 16, 2013 What's the largest amount of RAM a 7800 cart can have and can you bank-switch RAM like you can ROM? Allan It's 16K, this board is designed to technically support 16K x 2 RAM banks, it remains to be seen if the timing will work. Atari's 7800 doesn't follow standard rules, it's a PITA to get working in the first place. Actually, technically, one could put another RAM chip at $8000-$BFFF (or toggle 16K chunks of one chip to map into that area). But that isn't very practical, you would have to bankswitch $C000-$FFFF, which would be kind of painful to the programmer. Link to comment Share on other sites More sharing options...
Lynxpro Posted December 16, 2013 Share Posted December 16, 2013 A board with 1MB RAM and flash memory would sell out... Link to comment Share on other sites More sharing options...
CPUWIZ Posted December 16, 2013 Author Share Posted December 16, 2013 How about a quadcopter attachment for the expansion port, so it can hover around the room, while you play? Just paid for the MegaCart+ board run, ETA Dec.24th (yeah right!). LOL 3 Link to comment Share on other sites More sharing options...

The Usotsuki Posted December 16, 2013 Share Posted December 16, 2013 If I knew how, I'd consider using a RAM/ROM cart (possibly with an option to bank out ALL the rom for ram?) for a BASIC interpreter and a DOS. Link to comment Share on other sites More sharing options...
Blue Azure Posted December 17, 2013 Share Posted December 17, 2013 The board is a beauty! CPUWIZ ROX! I just wish it had a POKEY slot on it so I don't have to carry my XM around with me. In fact, make it a dual POKEY with dual bankswitch and NVRAM. That should keep the 7800 busy & warm, but not hot. Code Blue 1 Link to comment Share on other sites More sharing options...
