Converted MSM58321 to DEVCB2, uses level logic rather than edge detection for strobes (as per datasheet), added nvram interface as there are some configuration bits to save, added support for 12 and 24 hour. It defaults to 12 hour, but you can configure it in the driver to default to 24H. You can configure what year 0 is in the driver, which is used when setting the date at startup. [smf]
Allow reading from port A in output mode. Add a separate bit for timer 1 PB7 toggling rather than changing the PB register directly. Don't clear the SR register on reset. Clears pcr & acr at construct time, in case something sets one of the handshaking lines before we've started. Use a separate variable for the latched inputs and the current inputs. Consolidated the input and output code. [smf]
sharc.c: Modernized cpu core.  [Wilbert Pol]
Hooked up RTC. There are several issues. The day and month register are swapped. Even though it allows you to select between 12/24H the RTC is always saved in 24H mode and it always defaults to display in 12H mode. [smf]
added preliminary stop and reset to MSM58321 (nw)

Created a better logic-to-analog proxy approximating output impedance. This revealed some bugs in the code which have been fixed.

Basically, borderline schematics like

    TTL_7404_INVERT(c9f, c9c.Q)
    TTL_7404_INVERT(c9c, c9f.Q)
    SWITCH2(coinsw)
    NET_C(c9c.Q, coinsw.1)
    NET_C(c9f.Q, coinsw.2)

in which the switch connects TTL-Outputs to ground now work. In this case, the addition of an analog device (switch) cause the netlist code to treat the TTL outputs as "analog" and (re)connect all existing and future connected terminals to the analog output. 
The downside is a slight performance penalty. This penalty may be mitigated going forward by introducing "proxy-hints" for selected outputs.
