Hi Jeri, As far as I am aware, the SID was only ever available in 1MHz version - even the Rev5 ones fitted to the C65. The C128 clock-stretches the 2MHz waveform to 1MHz to write/read from the I/O area. There is no clock stretching in the C65 as everything else is capable of 4MHz operation (CIAs are on the PLCC chip). So it is simply left up to the programmer to "slow" before a write. As to the physical failure, I guess the writes don't take, the reads are invalid, and the poor chippie overheats if you pumble it at 4MHz..... - Nick -----Original Message----- From: Jeri Ellsworth [mailto:firstname.lastname@example.org] Sent: Wednesday, 9 May 2001 6:17 PM To: email@example.com Subject: SID Damage? Hi, I have read in C65 documents that running the machine at 4mhz and accessing the SID's will damage them. Does anyone have any more info on what is happening to them ?
