     confuse are
the 30 and the 55SX, as they came in the same case.  
 Model 40 and below are ISA, 50 series and above are microchannel. The
 30-286 and 55SX used the same case but the 30 (8086) had a similar but
 plastic beige/brown (as opposed to all beige steel) case.  
 Well, at least I've got a general idea what I've got stored away now. I
 may have to go unbury them tonight, just to satisfy my curiosity.  
 I uncovered the stack of machines. All of them are in fair to good
 condition, but missing their hard drives. They seem to be intact
 otherwise.

 2 - Model 55SX (8555)
 1 - Model 30 286 (8530)
 1 - Model 30 (8530)
 1 - Model 50 (8550)

 Does anyone know why IBM choose to use the same part number for the Model 
 30 and Model 30 286?

   : Do you mean the SN # ? Don't have a 30 286 to check but most
 :IBMs had a model subset that better described it like the 8580-111
 :8580-Axx or in the PS/1s for example the 2133-011. Mueller has 
 :most listed in his 3rd edition but not the SN #s. >>

All PS/2 models start with 85 or 95 for the model number. Serial numbers 
starting with 23 were built in RTP, NC. numbers starting with 78 were born in 
Greenock, I think.
