New Multi Calculator

[teenix]

Hi all,

I'm still fiddling around with the calculators.

I have put together a new calculator that emulates the original microcode of the following 19 models all on a single $4.00 chip.

Classics - 35, 35 (bug), 45, 55, 65, 67, 70, 80,
Woodstock - 21, 22, 25, 27, 29c,
Spice - 31e, 32e, 33e, 34c, 37e, 38e

The HP65 and 67 have a small memory card that can store up to 51 programs, but might soon have storage for up to 819 programs.

Once in menu mode you can scroll through each model and select the one you want to use. As the ROM code is already in memory it is ready to use immediately.

The picture shows the calculator waiting for the user to select the HP-67 as the operational model.

Still a couple of minor issues to iron out with the continuous memory models, but seems ok so far.

cheers

Tony
