Thread: What is the AMI Keyboard BIOS Plus chips on later PCs?

  1. #1

    Default What is the AMI Keyboard BIOS Plus chips on later PCs?

    Can anyone verify if this is just a clone of the Intel KB controller or can it/does it contain the NVRAM for CMOS and/or the RTC? Thanks.
    Current Wish List: 1. IBM 7531 Industrial Series PC 2. NEC MultiSync XL (JC-2001) Monitor 3. Copy II PC Enhanced Option Board (the one with the toggle switch on the back) 4. MicroSolutions MatchPoint AND/OR UniDOS card 5. Compaq 14" VGA CRT Monitor (the one that came with the SystemPro). If you have any of the above for sale please PM me. Thank you!

    Hi, I can't answer this directly. You can lift the label and check the engravement, though.
    I bet it's a flavour of the 8042 microcontroller (datasheets available on the web).
