Hi

The subject line says it all: I need some information (pin assignment, register
locations, interfacing) for the MSM 5832 and RTC 58321 clock chips (in view of
putting one of them onto my homebrew Z80 system).

I have one confusing piece of information: I read somewhere that the 58321 is
the pin-compatible successor to the 5832, just with the 32768Hz quartz
built-in. But the 5832 is a 18-pin chip, the 58321 is a 16-pin chip. What is
going on ?

Most important question: Which distributor carries the 5832 (Jameco sells
58321s).
