(MESS) Rainbow 100 updates: [Bavarese]
- added DEC-190-B model - preliminary floppy (TD0 / IMG) - corrected LK201 keyboard matrix (C12, Do + cursor keys) - MHFU changes; character display speedups - nicer bezel with 'C' + 'D' drive leds

--------------------------
|
||||
- FATAL: keyboard emulation incomplete (inhibits the system from booting with ERROR 50 on cold or ERROR 13 on warm boot).
|
||||
- NOT WORKING: serial (ERROR 60).
|
||||
- FLOPPY TIMING: 'wd17xx_complete_command' * must * be hard wired to about 13 usecs.
|
||||
Line 1063 in 'wd17xx.c' has to be changed (until legacy code here is removed):
|
||||
- w->timer_cmd->adjust(attotime::from_usec(usecs));
|
||||
+ w->timer_cmd->adjust(attotime::from_usec(13));
|
||||
|
||||
- WORKAROUND AVAILABLE: keyboard emulation incomplete (inhibits the system from booting with ERROR 50 on cold or ERROR 13 on warm boot).
|
||||
- NOT WORKING: serial (ERROR 60).
|
||||
- NOT WORKING: printer interface (ERROR 40). Like error 60 not mission-critical.
|
||||
|
||||
- NON-CRITICAL: watchdog logic (triggered after 108 ms without interrupts) still not exactly by the book.
|
||||
- NON-CRITICAL: watchdog logic (triggered after 108 ms without interrupts on original machine) still does not work as intended.
|
||||
|
||||
Timer is reset by TWO sources: the VERT INT L from the DC012, or the MHFU ENB L from the enable flip-flop.
|
||||
The MHFU gets active if the 8088 has not acknowledged a video processor interrupt within approx. 108 milliseconds.
|
||||
|
||||
BIOS assumes a power-up reset if MHFU detection is disabled - and assumes a MHFU reset if MHFU detection is ENABLED.
|
||||
Therefore a 'warm boot' within MESS (F3) causes ERROR 16.
|
||||
|
||||
As there is no reset switch, only a limited software reset exists on a real DEC-100 (CTRL-SETUP within SETUP).
