pk232.34

It always bothered me that the PK232 draws about 700mA while the KAM draws
about half that. Besides the need for mA there's the heat issue. I solved
both problems by replacing the CMOS Z80 with a CMOS part. Toshiba makes
a very nice version that saves 100mA and is a drop in replacement. I used
them with great success in a CP/M system up to 12MHz. I used to buy them
from a commercial source but have seen them advertised in Computer Shopper.
Too bad AEA doesn't use them. The PK88 could benefit from them too but
unfortunately it's is soldered in. -Jim WA2ZKD@WB2PSI
