For CPPM CS:

Enter PDT (level 2)
Print address 0xffff1528 as follows-

1) This CPM has BIOS version 15...
pdt d 0xffff1528 12 1
ffff1520 4e 54 44 55 37 34 41 41 NTDU74AA
ffff1530 20 31 35 00 15.............

2) This CPM has BIOS version 18...

This is interesting.

From the above it looks like the BIOS version is actually a hexadecimal number, both in the dmidecode output (not obvious) and when displayed through PDT (obvious).

So the decimal equivalents of the CPM BIOS data are 21 (0x15) and 24 (0x18) respectively.

I can see how this could raise a nugget of confusion if someone didn't know that the dmidecode BIOS version was in hexadecimal.
