Actually, I was reading a book recently, and it occurred to me that the 2600 could be used for the emulation of another machine, which is probably the ultimate insanity. The machine was called SADSAC--Simplified version of A Decimal Single Address Computer (big grin) and was created to demonstrate all the basic functions of a computer. It has one 13 bit accumulator, one 8 bit program counter and 20 or so op codes. For ultra simplicity in instructing newbies, it is a decimal computer, so the 8 bit program counter, organized in BCD, only allows an address space of 100 bytes. Every instruction consists of three signed BCD digits: one op code (-9 to +9) and one memory address (00 to 99). In the book, they translated several Fortran programs to it to demonstrate generic machine language organization... The 2600 could probably do this, complete with a joystick driven command prompt, machine language oriented line editor, a compiler, and everything ;) -- mor@xxxxxxx http://www.crl.com/~mor/ -- Stella list is Administered by krishna@xxxxxxxxxxxx <Glenn Saunders> Archives (includes files) at http://www.biglist.com/lists/stella/archives/ Unsub & more at http://www.biglist.com/lists/stella/stella.html +-shameless plugs-------------------------------------------------------+ | Stella documentary at http://www.primenet.com/~krishna | | Nick's VCS links via http://www.primenet.com/~nickb/atariprg.htm | | Write the best game, win framed autographs of famous Atari alumni!! | +-----------------------------------------------------------------------+
