HP97 The journey begins

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 card displays a series of messages then stops.

Hi Tony,

Can you make that program available as a memory card download?
From what I understand it should be possible to do this on an original 67 as well, but how would one go about that without the two new key codes?
Would it be possible to generate the messages with your emulator and then write them to a magnetic card and transfer to an original 67?

Probably all silly questions, but I haven't looked into this yet...

Cheers,
Harald
