Adding more info:

As I obsessed with this, I asked in other "abandonware" forums. In one of them one guy had three different versions of F-19. I copypaste the differences between each version, taken from the readme:

F-19 Stealth Fighter
Version 435.04, 5/16/89
Copyright (c) MicroProse Software, 1988. All rights reserved.


Changes for Version 4
---------------------


The promotion sequence has been corrected and now agrees with the manual.

The lockup on certain clones, particularly Lazers, has been fixed.

The divide overflow problem on certain clones/joystick cards has been fixed.

Mobile SAMs are now treated as SAMs (as documented) and not as bunkers.

A low altitude pull-up warning has been added to Realistic flight.

Missions with carrier landings and takeoffs work.

The autopilot problem associated with wide-angle views has been corrected.

CGA cockpit color usage has been improved.

The AdLib sound board is now supported.

Tandy sounds have been improved.

The Carlsbad bridge under the mountain has been fixed.

The Alt-H control for the Pitch Ladder has been added.

1) Please note the following color changes to
the CGA 4-color Satellite/Radar Map.

2) F-19 now supports the PC-compatible sound/game board produced by
Innovation. If you have this board, copy the file BSOUND.EXE from Disk B
to your copy of Disk A. If your copy of the A disk is a 360K 5 1/4" floppy,
then you must erase both ISOUND.EXE (the standard IBM sounds) and
TSOUND.EXE (the Tandy sounds) to make room for BSOUND.EXE. Finally,
whenever you load F-19, load it with "F19 /AB", which invokes the BSOUND
file.

Information about the board is available from Innovation, 1325 Juniper St.
Cleveland, WI. 53015 (414) 693-3416.
