Virtual H89 Computer Help

The JAR file VirtualH89.jar implements a complete core-H89, plus several peripherals. No external files are require to run the computer, however disk images are needed in order to run CP/M (or any other OS). This JAR file is typically run using this command: 

        java -jar VirtualH89.jar

The configuration of the virtual computer is driven by the configuration file, which is searched in the following way:

  1. The environment variable V89_CONFIG is used if present
  2. The current directory is searched for "v89rc"
  3. The path "~/.v89rc" is used (user's home directory)
The first message logged will be the source of the configuration. This file is plain text and consists of lines in the format "property = value". Long values may be extended to subsequent lines by using the back-slash to cause the subsequent line to be attached to the value.

The following properties control the basic functioning of the virtual computer:

h19_paste_rate, h19_paste_cr_wait
These are used to control the rate at which text is pasted to the computer console. "h19_paste_rate" is the rate for normal characters, in characters per second (values 1 to 1000). The default is 30. "h19_paste_cr_wait" is the delay in milliseconds used after RETURN, in place of h19_paste_rate. Default is 100 mS. These values are used to prevent overrun of the computer software for pasted text.
h89_log
Specifies a file to receive various messages and output that would otherwise be printed to the "Standard Error" stream in the command window used to start the virtual H89.
h89_disas
This selects the style of instruction mnemonics to use when displaying trace information. Either "zilog" or "mac80" (default). "mac80" selects Intel 8080 mnemonics with Z-80 extensions from the CP/M MAC/RMAC assembler macros in Z80.LIB.
h89_nameplate
This specifies the text to be displayed in the nameplate area of the computer housing. Default is "Heathkit H89". This text may be HTML, but there are practical limitations to what can be used. Some built-in nameplates may be specified by the PNG file name:

np-h19.png np-h19-2.png
np-heath1.png np-heath2.png
np-zenith1.png np-zenith2.png
np-mms.png

h89_image_sufx, h89_image_sufd
Define the file suffixes (file "types") used when mounting floppy disks. Entries in these two must correspond (i.e. the first entry in _sufx is paired with the first in _sufd). "sufx" is the actual file suffix, without ".", and "sufd" is the description for the corresponding suffix. Default is effectively: 
        h89_image_sufx = logdisk mmsdisk
        h89_image_sufd = Sector_Image Raw_Image
Which means that files of type "*.logdisk", "Sector Image" and type "*.mmsdisk", "Raw Image" will be shown by default in floppy image dialog windows. Note, "mmsdisk" is a deprecated format and not currently supported. Any "_" characters in sufd are converted to spaces.
model
Used to specify the H8 variation. Always includes an H19 and the console 8250 port. Also always uses a Z80 CPU. Includes the H8 Front Panel. Use "sw1" (instead of "sw501") for the system config dipswitch, but otherwise uses same properties as H89 - with some differences in devices.
