Hello! Martin Hoffmann-Vetter wrote: > Is there a problem with the power supply? The hard drive use the +5V and +12V. The dynamic RAM uses only +5V. What happens with the +5V? I measured the voltage in the running system and both +5V and +12V voltages are good. On a side note: I replaced the failed TMS4256 chip with a stock 41256 chip I had in my supplies, but it did not work. I thought all the x256 DRAM chips should be interchangeable? Is there anything special about the TMS4256? Regards, Michau. Message was sent through the cbm-hackers mailing listReceived on 2014-07-22 10:00:02
