HP41 GMAC module
Message #1 Posted by Hugh Wong on 21 Apr 2001, 10:56 a.m.

I recently purchase two 41cv(s) which does not work. However, it came with two GMAC (General Motors Acceptance Corp.) financil modules which probably come from a General Motors dealership. This financial module works something like TVM on my other HP41. Does anybody have any manual for it ? Is this module a HP41 standare accessory ?

I think that's a custom module given to GM dealers to calculate financing rates/payments, before they all got upgraded to PCs. It probably did come with a customized manual for the dealers as well.

Back in 1985 I purchased a Pininfarina Spider (Upscale Fiat 124 Spider sold in the US after Fiat pulled out.) from the local Buick dealer. The dealer had picked up the Pininfarina line and thought he was going to be the sports car king of Omaha, Nebraska. (Funny thing - no one came into the Buick dealer looking for sports cars!) Anyway, as we negotiated price, he used his HP-41C with the GMAC module to figure the monthly payment. It seemed too high so I pulled out MY HP-41C with the PPC module and calculated a much lower payment. The rather surprised salesman said he had "assumed" I would also want the credit life insurance! <g>
