	Brian i have a //e and and udc and a laser 3.5.  I was thinking
of installing a 65802 in my computer, but after reading your message
i'm not sure if i should bother.

	It seems that if your //+ works when the 802 is in the transwarp
that it will work on my //e pluged in the motherboard.  

What do you think???
