HP97 The journey begins

[teenix]

Hi all,

I successfully wrote to a card and then read it back this morning so it seems the CRC simulator code I have for the 67 works ok in the 97 :-)

It is a bit difficult to test the 97 due to the way it is constructed, but getting there.

The next stage will be adding the separate PIK processor and motor controller circuits. This will be interesting and will have to be enabled bit by bit with the print head disconnected until I know for sure the two processors are working properly together.

I have to minimize the printer handling because I don't want to damage the head ribbon. The new 97 CPU board has an easy release socket that connects to the printer ribbon socket so I don't have to keep pulling the ribbon out every time I need to separate the printer.

cheers

Tony
