Quit to DOS
Quits and exits to the DOS
OS Shell
Exits from the RFG temporarily to the DOS prompt. Type <EXIT> to return to the RFG main menu.
Load PFG File
If this option is used, the RFG will prompt you for the PGF file name. This option is useful if you have not
previously entered a PGF name or you wish to use a different PGF file. The RFG will check and display the
PGF filename, ROM pattern file name, EPROM capacity, DOS version and the number of ROM pattern files
that will be generated.
Type Current PGF File
This option instructs the RFG to use the DOS type command to display the contents of the current PGF file.
Generate ROM File(s)
If there is no mistake in your *.PGF file, then this menu option will generate ROM pattern files. The number
of ROM pattern file generated by the RFG will depend on the total capacity needed by your files. For
instance, if 3 files are generated, then you will need to use 3 EPROMs (The size depends upon the number
stated in your PGF). The ROM pattern files will have the same file names, but will have different extension
names. For example:
TEST.R01, TEST.R02, TEST.R03…etc.
Display Error in PGF File
This option displays errors that were detected in your PGF.
Help to PGF File
This option gives information on how to write a PGF file and how to generate ROM pattern files. An
example PGF is also included.
Move the reverse video bar to <Generate ROM File(s)> then press [ENTER]. The ROM pattern file is a binary file.
The file size will be the same size as the EPROM that you assigned in the PGF. For example, if you are using
128KX8 EPROM memory chips, then the size of ROM patterns file will be 131072 bytes. For other chips the file
size will be:
64KX8 EPROM----65536 bytes
256KX8 EPROM—262144 bytes
512KX8 EPROM---524288 bytes
1MX8 EPROM -----1048576 bytes
(E) RFGDEMO.PGF
RFGDEMO.PGF This file provides a sample PROGRAM GROUP FILE which illustrates how to create ROM
pattern files correctly.
The PGF is an ASCII text file that can be created by using any text editor, word processor or DOS <COPY CON>
command. The PGF lists what files will be copied and if DOS is going to be copied. This file can have any DOS
filename, but the extension name must be *.PGF. For example, followings are valid filenames.
