I remember recently reading one or two endorsements for the Inboard 386
as the best solution to upgrading an XT, and am seriously considering
getting one.  Before I do, however, I wonder if someone could provide
me with some more specific information about it, such as:

  - Does anyone know whether it will/won't work in a Zenith 159?
  - What type of RAM does it use?
  - Is the 1 meg on the board enough, or should I also get the 
    daughterboard? 
  - Can I get a daughterboard with 0k?
  - Will the daughterboard take single banks of 256k, or do you have to
    add to it 1 meg at a time?
  - Do I really have to pull all my current RAM (150ns), because it can't
    use it for anything (expanded, extended, RAMdisk)?
  - Does it get its power from the backplane, or does it need its own
    connection to my power supply? (which I don't have any more of)
  - Do I get to remount my 8088 on the Inboard, for going back to
    normal XT mode, or do I just throw it away?
  - Any ballpark figure on what kind of speedup it will give? (According
    to PCtools, my machine currently runs at 160% of a PC)
  - Also any other comment on the Inboard someone thinks relevant
    (horror stories, kudos, whatever).
  
E-mail welcome. 
If there's interest, I'll post responses. (I might post them anyway).
Thanks in advance.  Merry Christmas.
