Still, there is a certain system there. I haven't been able to quite figure out the system of IBM (which doesn't mean that there isn't one) FI the type 7012 and the type 7030 are almost identical, while the 7043 has completely different reference plaforms (PReP for some, CHRP for others).
Ironically HP still uses 9000 families for even some of the recent products (visualizes and Itaniums still have an internal 9000-7xx 9000-8xx and 9000-9xx branding).
From what I can gather, 43P is/was the minitower/desktop AIX line, and the 44P is/was the deskside AIX workstation. There are 3 types of 43p, all use a similar chasis, two use a PPC (604s) and the -170 and up use Power3 of some sort. 44s are all POWER I believe. I only know this because I was given a 44 machine and I had to track down a copy of AIX (and even when doing unix, IBM has AIX as a bit of an odd thing) and there were some point versions of AIX that did not support specific machines.
At least in the old days, it made more sense with the POWERStations/servers (7013/7012/7011) series. And then after the mid 90s everything went kookoo in IBMland. Their processors are even more confusing... After POWER2, it went P2SC, POWER64 (I-II-II), POWER3 (I-II), etc. Going to an IBM technical conference is also a trip, they have their own definitions for things that 90% of the industry uses different names, so one has to have a sort of IBM-to-rest of industry dictionary. Heck in some odd systems they still have their own digit encoding other than ASCII, and their own FP representation. IBM was so huge that they could afford to basically give the middle finger to the rest of the field and follow their own definitions.
Same happened with SGI, at some point you knew exactly the family, number and speed of processors and graphics capabilities of the system (ie. 4D330VGXT). Simple and somewhat techno sexy name, but noooooo... at some point someone decided: "lets give'em colour names" and then you end up with an Indigo2 which is actually teal or purple and you have no idea whats inside
