For review/comment especially by @rb6502 and Hans Ostermeyer because it's:
* a rewrite/replacement of prior work, and proposes taking over the copyright as well; and
* untested on Apollo at the moment because the driver is crashing while trying to install Domain/OS (unrelated to this device).
Testing with the 3c505.exe diagnostic program on MS-DOS passes the Group 1 & 2 tests successfully when using 16-bit DMA channel. It intermittently fails the Group 2 transmit test when using an 8-bit channel.
Now athlon xp supports WrMem and RdMem bits in fixed range MTRRs
Accesses to the first megabyte can be directed to system memory (ram) or
memory-mapped-io (mmio) (the pci bus)
Above 1mb accesses below the top_mem MSR address ram the others mmio
At reset everyting is directed to mmio
Addresss spaces work in the following way
AS_PROGRAM is used for ram
AS_DATA is used for mmio
AS_OPCODES is used by the debugger disassembler and in memory views to
look at the memory contents from the point of view of the
microprocessor, including the cache
Also some class members have been added to the save state
The kungfu master schematics differ from the kidnik schematics in
wiring D4, D5 and Q4 with other components. The manual corrections
to the kungfu master schematics make sense and thus are used here.
opamp XU1.B according to schematics has no feedback loop between
output and inputs. The arrangement of components in the schematic
however indicate that this is not the case and indeed a connection
exists. This results in sounds at output XU1.14 to contain more
detail.
improvements.
- fix MB3614 parameter
- Added VARCLOCK which derives step size from function
- optimized function handling in CS and VS
- fixed a bug in ppreprocessor
- add trunc to pfunction
- added opamp_amplification_curve to derive characteristic
amplification curve
- Untie diode code
- Fix some typos
- add TYPE=2 opamp model which omits output voltage limitation
Useful for determining causes of non-convergence
- Fix MB3614 opamp parameters to match datasheet
- Marked royalcrdc graphics ROM roj.ic26 as bad dump.
address line 08 is faulty, so you have 0x100 bytes blocks repeated
along the dump.
- Reworked jolycdig and added default NVRAM.
- Added button-lamps support to jolycdig & jolycdab.
Both games were promoted to working state.
- Added technical and game notes.
Machines promoted to working
