Yet another CoCo & MC-10 site

Dedicated to the Tandy/Radio Shack MC-10 Micro Color Computer and the Color Computers 1, 2 & 3


It has been rumored that Tandy (along with Motorola) is working on a CoCo IV computer to be released shortly. At present the only advance information available is that a new microprocessor will be incorporated into the unit-- the 6813!

Our research staff has been able to uncover a list of new opcodes that distinguish the 6813 as a breakthrough in computer technology. The list is presented here for your information.

Besides having the above user friendly opcodes, the 6813 will also have 161 easy to remember addressing modes! P.S. There is no word from Tandy as to when we might expect these improvements (they are still trying to figure out what a 6809 is!). Perhaps in the next computer catalog.



Actually, this was first edited using the HTML editor found in Netscape Gold (remember this one?), back then the page resided in the Delphi personal web space. When that died, the page was moved to Tripod and maintained with (oh sacrilege!) MS Frontpage. I got wise, moved out of Tripod and now use NetObjects Fusion...
