Both the model 25 and 30 came out in 8086 and 286
versions. The 25 had 2
286 models. 25-286 and 25LS. The models 50 and 60 were also 286s'
The models up to (but not including) the 50 series were ISA and after that were
microchannel. The 25 came out originally as an XT class machine with an 8086
processor ( see http://www.can.ibm.com/helpware/8525.html ) and the 286 version of
it was only one version that I'm aware of as seen at
http://www.can.ibm.com/helpware/8525286.html
The LS may be an aftermarket version, much like putting a Reply motherboard into
one.
