HP97 The journey begins

[teenix]

Hi all,

As well as the emulator, the new HP67 CPU board is able to process the display messages now. As I mentioned the HP-67 microcode has not been altered to make this work. The emulator is simply asking the microcode to accept and process the 2 new merged key codes.

There are two modes of operation selected during programming.

[h][A] displays a message and stops program execution
[h][B] displays a message and pauses the program then continues

The messages can be edited from the emulator program and another program I created for the new CPU boards. This latter one can also upload the message database to the new CPU board.

Here is a small video presentation of the 67 running from the new CPU board. I loaded a program stored in its memory at Block [0] Program[00]. This program card displays a series of messages then stops.
