a601
Hi All,
Sorry for reviving this old thread, I just got an A601 with 1/2 a Meg of RAM. As the thread is old, the links are not working and the imagery is all gone.. so I dont know what I am looking at. There are places for 3 RAM chips, the one fitted is a 4 megabit one (512K bytes) - I am rather puzzled by 3 spaces (the RTC is obviously not fitted) Can I just pop another 512K chip and all is good in the land? Best Regards, Richard |

The problem is everyone used the name A601. Are yours real CBM A601 or 3rd party? They should be so simple.
