Hi Ron,
Many thanks for returning to us and a belated Merry Christmas to you. Many of us are trying to correct our Webpages as a result of all the information that you have provided, and I am sure that we will have to rewrite a lot more as a result of all the new information that you are giving us.
In addition to correcting the computers with your Authorship, I have been trying to also correct the hardware where possible as well based on the information you provided in your computer listing. Hopefully you can recall some hardware details to help us correct any mistakes we might be making.
1997 Excalibur Chess 6805 4K Chess 7/23/1997
1997 Sabre 6805 4K Chess 7/23/1997
1997 Squire 6805 4K Chess 7/23/1997
1997 Kingmaster II 6805 Chess & Checkers 7/23/1997
1997 Travel Kingmaster II 6805 Chess & Checkers 7/23/1997
1997 Crusader 6805 Chess & Checkers 7/23/1997
In the above list I can follow all the computers except for Sabre as it seems to be a computer from pre 1995. Sabre II I think came out in 06/95 based on a time sticker on the computer (which may also be a meaningless sticker). You do have Saber III missing on your list however that should fit nicely into your timeline above, especially since its design is similar to Crusader that matches your timeline. Is it possible that Saber III Model 901-E3 is meant under Sabre?
Based on your invaluable information we did find a spec sheet for the 6805 and have been able to fill in the hardware gaps. However as a couple of the 6805 in your list state 4K I am still not sure if the ROM should be 4 KB in size. It would be great if you could recall and confirm this.
With Alexandra we are still unsure about its speed the spec shows 5 MHz but we don't know if perhaps you used at 10 MHz or 12 MHz quartz as well.
Lastly with Chess Station:
Are we correct in assuming 6 MHz?
Very many of your designed computers have the above 3 ROM's therefore in getting it right on the above three computers, it will help us a lot in figuring out most of the other Excalibur computers.
Many thanks and despite our all our heated debates from passionate people that we all are, we do all have one thing in common which is that we all do love your posts and we are all honored that you are here sharing with us your past.
Many thanks and best regards
