Release uBee512 v1.00 sources and Windows binaries on sourceforge:
https://sourceforge.net/projects/ubee512/

3 July 2007 - S.J.Kay
---------------------
Added an 'in (c)' also known as 'in (hl),(c)' to the makez80.c file.  This
instruction is an documented Z80 instruction but quite valid I beleive. The
instruction is similar to the 'in a,(c)' instruction but no value is
returned except for the flags.  This was added for some Z80 code I wrote
that used it.

----------------------
Discovered there was a much later version of MZ80.  The latest version is
now being used v3.4.  Previously v2.7 had been used.  The newer version of
makez80 insists that an emit parameter is provided otherwise you you end up
compiling with the old mz80.asm still! The new version fixes the cycle count
returned and appears to be quicker as eluded to in the change history.

Also found that some applications that did not work previously do now with
the newer version.

Welcome to the "uBee512" Microbee Premium disk model emulator. This is a
fork of the nanowasp v0.22 project and commenced on the 5th of June 2007.

The new project includes a large amount of additions and improvements over
v0.22 of nanowasp. The new fork is "uBee512".
	
Changes/additions planned for the first release v1.00
-----------------------------------------------------
- Convert memory emulation to 512K DRAM system.
- Full Premium model Microbee graphics hardware emulation,  32K PCG, 8K
  screen, 8K attribute, and 8K colour RAM.
- Premium (Alpha+) emulation of the hardware inverse and flashing video
  defined in attribute RAM. 
- Speaker sound emulation.
- Fully mapped keyboard to emulate all keys correctly.
- Speed execution accuracy and regulation to be improved.
- All 6545 cursor modes to be supported.
- CRTC for the VBLANK status to be improved.
- add options for colour and monochrome monitor types
- Full screen mode.
- Alternative and Turbo speeds mode option.
- Screen to be resized to suit the current current 6545 registers.
- Convert disk image formats to use information header describing disk
  images.  This will allow many different disk image formats to be read if
  supported by the Z80 operating system.
- WD2793 emulation to support sector sizes 128, 256, 512 and 1024 bytes.
  512 byte sectors, 10 S/T and 40T DS disks are no longer to be assumed.
- Disk images to be writable (with write protect feature)
- Disk images mountable on A: B: C: D: and images selectable from a menu.
- Correct mapping of all the Microbee keys on the IBM keyboard.

Future changes and additions
----------------------------
Later additions may include:
- Command line parameters/configuration file.
- Parallel printer port emulation to file.
- tape in/out emulation to file.

Support programs:
* GUI interface.
* Utility programs where required.  This should include the following:
    - A utility to convert existing disk images.
    - A utility to create images from microbee disks from a <= 386 IBM PC
      including the 5.25" disks that have side 0 format error bug.
