ROS Code / Function _ CRC32 _ IBM Reference

ROS Codes are given by the PID-1200 routines of the firmware.
Functions are given by me, the dumper. Here is a list of functions:
    * CHR - Character Generator ROM.
    * KBD - Keyboard Microcontroller Program.
    * FDC - Floppy Disk Controller Card Microcontroller Program.

Example 1:
    10_41e6c232_8519411.bin
        * ROS Code: 10h
        * CRC32: 41e6c232
        * IBM Reference: 8519411
Example 2:
    fdc_b6907e77_8493564.bin
        * Function: fdc (floppy disk controller card microcontroller program)
        * CRC32: b6907e77
        * IBM Reference: 8493564

======== Use and positioning ========

All 1KB images are meant for its usage with a 8048 microcontroller. They can be used in 8748/8749 devices without compatibility issues.
All 8KB images were extracted from MK36000 memories and will require an adapter to be used with series 27, 28, 29 or 39 of memories.
The placement of the memories depends on the image references included in this package. Note that 14 ROM boards have a different placement than 16 ROM boards.
Replace only a ROM if its IBM reference coincides.
Many images from this collection have the same contents and CRC32. They have been left because their IBM part number is different.

======== Versions ========

* 1.01
* 1.03
* 1.04
Versions 1.02 and 1.05 are still missing.
