Hello,

I have a Toshiba/Hitachi DT01ACA200 with faukty PCB attached.

I swap ROM, PC3000 goes imediatly to ready but motor doens't start. DO I need to change any other chips (NV-RAM) If yes, ca you help me to identify it on the PCB?

Thanks & Regards,

I believe that the "NVRAM" data are in the "ROM". If you upload your ROM dump, someone may be able to identify the problem with it.
