Support QP/M TIMDAT Routine

Browse Source 
QP/M is a CP/M 2.2 replacement for BDOS/CCP.  However, it adds it's own concept of date/time stamping.  Support for the QP/M date/time routine has been added.  You can configure QP/M to find the vector at address 0x0010.

A sidenote on QP/M.  By default, it uses 2 bytes at address 0x0008 to store the current drive/user.  This will conflict with RomWBW's use of RST 08 for API function calls.  I recommend using address 0x000E when configuring QP/M for the location of the current drive/user.

Font files for ROMWBW.
8x8: 8x8 cell, mostly IBM CGA, first 16 differ, thin font
8x11: 8x11 cell, possibly VT-100?
8x16: 8x16 cell, IBM MDA
CGA: 8x16 cell, IBM CGA, normal (thick) CGA font, rows 8-15 are unused padding
There are three fonts associated with ROMWBW supported hardware - ECB-SCG, ECB-CVDU and the ECB-VGA3.
Name Format Size Board & Display Mode
------------------------------------------------------------------------------------
font8x8u.bin 8x8 2048 ECB-SCG, ECB-VGA3 (80x60)
font8x8u.bin 8x8 2048 ECB-SCG, ECB-VGA3 (80x60), MBC-VDP
font8x11u.bin 8x11 2816 ECB-VGA3 (80x43)
font8x16u.bin 8x16 4096 ECB-CVDU (80x25), ECB-VGA3 (80x24, 80x25, 80x30), MBC-VDC
fontcgau.bin 8x8 4096 ECB-CVDU (80x25), MBC-VDC
fontcgau.bin 8x16 4096 ECB-CVDU (80x25), MBC-VDC
For inclusion in HBIOS the .bin format files must be convert to assembler .asm format.
Notes:
- The CGA font is roughly equivalent to the 8x8 font, but padded out to 8x16. Scan lines
8-15 are unused. The CVDU driver (8563 chip) always uses fonts defined in an 8x16 cell.
When the CVDU is configured for use with a CGA monitor, an 8x8 character cell is used,
but the font definition must still be 8x16. The CGA font is used for this.
For inclusion in HBIOS the .bin format files must be converted to assembler .asm format.
This is acheived using the fonttool utility and is completed automatically as part of the build process.
i.e. fonts files are converted to .asm format and then copied to the HBIOS directory.
