Request: Caboose firmware (for the Quadra 900/950) - part number 341S0853

[jaronpolo]

Hello all,

Just to preface: I'm not entirely sure if this is the correct place to ask, but it seems like a good candidate to me.

Anyway, I was wondering if anyone could share a dump of the Apple Caboose firmware, version 1.00. It has an Apple part number of 341S0853. As far as I am aware, it is a custom M68HC05-based microcontroller that was used on the Quadra900 and 950 logic boards, to manage the RTC + PRAM. A close relative to the Egret chip and a direct predecessor to Cuda.

I've seen in various places that a MAME developer going by R. Belmont has this firmware, so is there any way I could contact them if no one else has it?

Thank you!
