IBM RS/6000 43P-140 specific notes

PrevUp

Machines of this type were quite popular towards the end of the 1990s, for general desktop workstation use and in particular for CATIA, provided enough RAM and a decent graphics card (GXT550,GXT800,GXT2000). They certainly won't win a beauty contest (IMHO) but they were/are reasonably priced workhorses.
I have foreseen it mainly as an AIX 4.3.3 reference machine,

RAM

The DIMMs for models 140, 240 and 150 have FRUs as follows (excerpt from Install & Service Guide (pdf)):
  140 240 150
16MB 42H2772 (1-6) 42H2772 (2-8)  
32MB 42H2773 (1-6) 42H2773 (2-8)  
64MB 42H2774 (1-6) 42H2774 (2-8) 19L1808 (1-4)
128MB 93H6823 (1-6) 93H6822 (2-8) 19L1809 (1-4)
256MB     29L3302 (1-4)

The numbers in parantheses indicate how many of the respective modules can be installed. An even minimum number indicates that the modules must be installed in pairs of equal capacity.

Tape drive

Same comments as for the 43P-240 apply.

CPU fan

These are parts which tend to get noisy (or even break) over time. Mine was a "SUNON KDE1205PFB2-8 DC12V 0.7W" and could be replaced with a PC-type fan (Pentium class).
