Excalibur Chess Products Ron Nelson designed/programmed

[ChessChallenger]

Well here is my Excalibur Timeline.
I added a few from my Fidelity days, since they don't seem to be correctly described on some of the Chess Computer history sites.
This is comma separated text, which you should be able to import into a spread sheet.

In finalizing my Development spread sheet with pictures, I found two errors.
A typo for Saber IV having 18KByte ROM when it should be 8KByte ROM.

The other was Little Chesster external ROM at 1 MByte it should have been 1Mbit or the preferred 128KByte ROM.

Corrected CSV data:

In 2000. with the start of LCD Chess, I started putting software version number displays in the product.
Generally, if a unit displayed the move number at New Game, I would display the software version there and then switch to displaying move number 01.
LCD Chess best version was 1.7
King Arthur was 2.7
Later with my Universal Chip used on multiple products it was 3.7

But on some products I would only show the software version during the factory Test Procedure.

Here is the test procedure for Alexandra:

In finalizing my Development spread sheet with pictures, I found two errors.
A typo for Saber IV having 18KByte ROM when it should be 8KByte ROM.

The other was Little Chesster external ROM at 1 MByte it should have been 1Mbit or the preferred 128KByte ROM.

Corrected CSV data:

The software was written for a multi-game system we were designing,by my software group based in France, that worked on European games and card games.
It was demoed by them in Miami to Sid and he liked it, but wanted a stand alone unit.
My engineer, Rick Merrick then converted it to a single chip micro.
There was some type of bug that it would NOT tell your fortune "correctly" if you put in Sunday as your day of the week.
We called it the "Never On Sunday" bug...or if you know the movie...Taro never worked on Sunday, wink wink.

since it will predict incorrectly I guess it will probably tell me I will grow up to be handsome and Famous
