I have a VAX 4000/200 in a very unusual rack mount BA400 series cabinet. 
The drives point out the front and the cards mount in the back. I do not 
have the 'slides' for this chassis. I would be willing to trade it for 
KA694 (VAX 4000/705A) CPU module. The 4000/200 includes a TK70 and a RF72 
disk I believe. It takes BA400 type disk/tape cards. It has 32MB of RAM and 
a CXY08 async mux card. I'll pay to ship it to you on a pallet if you live 
near one of Forward Air's terminals.

Yes, I know KA694s are sold by resellers for a lot of money, and no I don't 
hold out a lot of hope that someone will be interested in trading one 
single card for a complete system, however I had to ask. The alternative is 
to start selling VAXen on Ebay until I've made enough to pay for a 694. :-) 
[The astute will wonder how many VAXen that will take, I don't know but we 
just might find out...]
