IBM 5150 PC 64KB-256KB 8088 Motherboard w/ 256K RAM 6137399 - TESTED - READ

Tested, and boots to DOS 3.3 with no RAM error.
BIOS ROM is 10/27/82 revision.
NOTE!
This one is missing 2 of the 4 Cassette BASIC ROMs.  Because of this, it gives an F600/F800 warning at boot.  If you don't care about ROM BASIC, this is not an issue.
