The 610 can be expanded up to 1MB (960KB to be exact, the system segment doesn't have RAM). I have such a machine here. It needs almost forever when testing the RAM on startup:-) There is no kernal to utilize the additional RAM. If you add kernal and basic from a 620, it is possible to use 256K for basic programs. Machine language programs are able to use all of the memory of course. Regards Uz -- Ullrich von Bassewitz uz@musoftware.de Message was sent through the cbm-hackers mailing list
