New HP find

You do realise that this is a _very_ nice calculator (I am still using a lot of 41 stuff here, CVs (a C with 5 times as much user memory), CXs (a CV with built-in extended functions ROM, extended memory, real time clock, and a bit more), and various plug-in modules. The problem with the C is the limited memory. You really want to add a Quad Memory Module to bring it up to the CV specification. Apart from that, the card reader and printer mean you have a nice system. Be warned the 41 series are adictive. You start playing with them. Then you want an HPIL module and all the peripherals (digital cassette drive, disk drive (!), Thinkhet printer, Plotter, DMM, etc). Then you start doing things HP didn't intend, like synthetic programming (which is creating 'illegal' instructions in user programs). When you lose interest in that, you want an MLDL box (a special RAM unit which emulates a ROM module) so that you can program the darn thing in machine code. This happened to me... -tony
