I had a original IBM PC with the 64k motherboard and small power supply. A 
friend bought an XT as soon as they came out and it had the 256k 
motherboard. I don't think they ever made a 64k XT.

Later I had my BIOS upgraded to install a 20 MB hard drive. (And a power 
supply upgrade.) I had to take my computer to an authorized IBM dealer to 
get the BIOS swapped. They would not just send you a ROM. Even with an AST 6 
Pack I did not have 640kB or RAM because of the 64k motherboard. (But I did 
have a cassette interface.)
