We might as well replace them if we have the opportunity. Here are some things to consider when designing a the mobo. If I'm replacing the mobo, I think I'll just setup my Super-64 in a PC tower case. The new board ought to be designed with this in mind. Also, there should be a connector for a PC keyboard and included logic to decode PC keypresses as equivalent C-64 keys. Might be a good idea to allow people to customize the decoding matrix too, perhaps by writing the new matrix into a PRAM-type area? Make the KERNAL customizeable. Maybe have it copied to RAM on power-up. Then implement KERNAL patches by loading them from the PRAM-type area. Now I can customize my KERNAL without loading from disk or burning EPROMs :) The cassette port can definitely be ditched. Same thing with the RF output. The User port is not essential, but would be nice for connecting audio/video digitizers and printer devices which already exist and require it. Slots are very desireable. They ought to mimic the Expansion buss and be switchable as in the multi-cart expansion boards. Each slot should be fully enable/disable controlled by both hardware AND software switching. It should be possible to enable multiple slots when carts are compatible (of course only the user can determine this.) There should be nothing stopping me from using my SuperSnapshot and SidSynphony simultaneously. 65816 socket is a MUST so we can write sophisticated new apps to take advantage of the new hardware. It would also ease the burden of developers who are willing to port their SuperCPU apps. Other desireable features include ETHERNET, IDE, USB, SCSI and true RS-232. I won't be satisfied until I can connect my cable-modem to my Super-64 and browse the web with full graphics :) ===== Get a FREE 6Mb webmail box from go6502! - http://www.geocities.com/profdredd As low as 2.99% Intro APR from NextCard! - http://www.nextcard.com/index6.html?ref=aff0074521 PayPal is the FAST FREE and SECURE way to send money! - https://secure.paypal.x.com/refer/pal=profdredd%40yahoo.com __________________________________________________ Do You Yahoo!?
