Subj: XR4

Rick, here's my situation.  I have a 102 with the UR2 in the ROM and the two
RAM slots filled with 8K modules.  I would like to buy the XR4, then add my UR2
to the XR1, but a ROM Sardine and add it to XR2, then use XR3 and XR4 for extra
RAM storage.  At a later date, I would probably buy Tri-Mike Network's Super
rom and add it to XR3.  How does this XR4 work?  Do I physically remove my UR2
chip from the machine and then place it physically in teh XR4 or is this
accomplished by some other means?  If I just want to use the XR4 for the RAM
space, do I have to buy RAM modules.  Lastly, on the Node, where does this
external module hook onto?  Is it the system bus?  Thanks for your trouble in
answering these questions.
