NAME

6       psfs2mda - extract the font from a dump of the IBM PC MDA ROM
7

SYNOPSIS

9       psfs2mda  [--compaq]  [--comment=text] INPUT14 INPUT8 [INPUT8_ALT] OUT‐
10       PUTFILE

DESCRIPTION

12       psfs2mda generates an MDA character ROM image from two  or  three  PSF-
13       format  screen fonts. The output file can be used to create a new char‐
14       acter ROM for an original IBM CGA or MDA, or (with the --compaq option)
15       a Compaq CGA.
16
17       You must supply either two or three input files. The first file is used
18       for the 14-pixel font, the second for the 8-pixel font, and the  third,
19       if  present, for the alternative (thin) 8-pixel font. If the third file
20       is not present, psfs2mda will attempt to use characters 256-511 of  the
21       second  file.  If the second file only has 256 characters, the alterna‐
22       tive 8-pixel font will be the same as the main 8-pixel font.
23
24       Note that the physical ROM chip used in an IBM MDA or CGA  is  a  9264,
25       with a pinout which differs from the normal 27xx range.

OPTIONS

28       --compaq
29              Output a ROM image suitable for the Compaq Portable/Deskpro CGA,
30              rather than the IBM MDA/CGA.
31
32       --comment=message
33              When outputting in Compaq format, it is possible to embed a mes‐
34              sage  (usually  a copyright message) in unused bytes of the ROM.
35              This option sets the message to include.
