Known bugs and restrictions of Emu48 V1.10
|
|||
|
|
------------------------------------------
|
|||
|
|
|
|||
|
|
- input cursor blink frequency on stack view is wrong when a key is
|
|||
|
|
hold down
|
|||
|
|
- the POWERCTRL register (0x109) isn't emulated
|
|||
|
|
- bit 3 [UCK] of the BAUD register (0x10D) isn't emulated
|
|||
|
|
- the bits of the SRQ registers (0x118,0x119), except the KDN bit,
|
|||
|
|
aren't emulated
|
|||
|
|
- the baudrates 1920, 3840, 7680 and 15360 aren't emulated on most
|
|||
|
|
operating systems
|
|||
|
|
Windows 95a 1920, 3840, 7680 work, 15360 fail
|
|||
|
|
Windows 98 all baudrates fail
|
|||
|
|
Windows NT4.0 SP3 all baudrates fail
|
|||
|
|
- System-RPL commands VERYVERYSLOW, VERYSLOW and SLOW depends on PC
|
|||
|
|
speed (are realized as simple down counter in ROM)
|
|||
|
|
- in all original KML scripts Color 7 is missing in the LCD section
|
|||
|
|
- because of correcting the RGB order in SetLcdColor() the LCD
|
|||
|
|
background color may be wrong in some KML scripts
|
|||
|
|
- display updating differs from the real machine
|
|||
|
|
- screen VBL counter values may skip after large display operations
|
|||
|
|
like turning on or updating the whole display
|
|||
|
|
- read on an unconfigured address (open data bus) will not show the
|
|||
|
|
same value like a real calculator
|
|||
|
|
- the G(X) hardware signals BEN and DA19 aren't fully supported,
|
|||
|
|
because the emulator don't use a multiplexed AR18 / NCE3 data line
|
|||
|
|
-> all programs that run on a real calculator will run as well,
|
|||
|
|
programs with incorrect DA19 / BEN handling may run on the
|
|||
|
|
emulator and will crash on a real calculator
|
|||
|
|
- no beeper support with OUT command -> all programs that aren't
|
|||
|
|
use the "=makebeep" subroutine, like alarm wake up, have no sound
|
|||
|
|
- beeper emulation, ATTN key doesn't work,
|
|||
|
|
Windows 9x: plays only default sound event or standard system beep
|
|||
|
|
- no infrared printer support
|
|||
|
|
- Shell OS: clock isn't synchronized with real time
|
|||
