The fact that the PCB part number in an HP product has
a particular rev
level almost never has anything to do with the suffix of the model number
(e.g., 9915A or 9915B). For instance, the HP-95C and HP-95LX, which
aren't even *similar* products, have 00095-xxxxx parts, with various
PCB revs, as does the HP-9807A Integral PC. (Maybe the Integral was
originally going to be designated an HP-95 with some other letter
suffix?)
In the HP catalogs it's called a HP 9807! For the ones of you that aren't
familar with HP stuff. The HP 98xx series was their desktop calculator line. They started
with the 9805, then the 9810, 9820 and 9830 were released together, later the 9815, 9825,
and 9845 were released simultanously. The 9821, 9831 and 9835A & Bs were intermideate
machines. Later they came out with Motorola 68xxx based machines called the 9816, 9826,
9836 and 9920. The Integral doesn't fit into any of those series anywhere and has
NOTHING in common with any of them other than having a 68000 CPU. In fact, the IPC was
designated as a replacement for the HP-85! You'll find lots of quirky things in
HP's model and part numbers!
