Capacitors G-Luxon SM 105 deg C:

I notice that the capacitors used in the switching power supply are
standard types. Preferred capacitors would be low ESR types, eg the
LM or HM series.

http://www.rockpark.com/soundcards/soundpro.htm
http://www.rockpark.com/soundcards/1869.htm (ESS chip, not CMI chip!)
Note that the sound chip is actually a C-Media Electronics design
whose only similarity to the ES1869 (from ESS Technology) is in the
package style. Curiously, while the CMI8330A is rated very badly by
Rockpark, the performance of the ES1869 is quite acceptable. Hmmm.

I/O chip IT8770F = IT8661F (PC98 Super I/O without KBC&RTC):
http://www.ite.com.tw/desktop/it8661f.pdf (data sheet)
mailto:willy.peng@ite.com.tw
Is this chip an OEM version of the IT8661F? ITE told me that the
IT8770 and IT8661 are identical. So why the part number change?
Are there any known problems with the IT8661? Does the IT8770 have
bug fixes or performance enhancements?
Can the UARTs support DTE speeds of 230400bps and above?

http://www.sis.com.tw/ftp/Drivers/Multimed/jedi/597v113.exe (VGA TSR)
The SiS 5597/5598 data sheet states that "the SiS chip is designed to
support Pentium CPU host interface at 75/66.667/60/55/50MHz". This
implies that a frequency of 83MHz overclocks the chipset.
