Nope,  but I can do uuencoded email just fine...

What about 8-bit cards?  (Some of these are 8 bit.)

While I have an Adaptec SCSI card on hand,  I'm not using it in any of the 
machines at the present time.

I did try 300h and found that I was running into problems with something or 
other.  With trying some of the cards I don't have info on,  one of them 
showed me a conflict with a dual serial port card that happened to be in the 
test fixture at the time,  which I've since removed.  Another one gave me a 
blank screen and now that IDE/Floppy card won't do the floppy seek any more. 
:-(

Do I *need* a memory aperture on all of those cards?  One of the Samsung 
cards has a boot eprom on it,  none of the rest do...
