I've got the 68HC11 version of the ET-3800 just acquired for probably 
more than I should have.  Anyone have any software / experience with them?

There appears to be a big box on Ebay for sale (x a couple of units for 
sale separately) for this as well, or maybe it is for the 3400.

I'd be interested in what people have.  Mine came with the processor 
personality and the memory module only.
