If you look carefully down the list, he's got an M8047 - MXV11 with 
(P)roms,
so he'll be able to use the 11/23 that he already has, and, depending 
on the
roms installed, should be able to perform an MSCP boot.

Entering bootstrap by hand?  Eeek!   That is what macros on terminal 
emulators are for.
