Sandy TSB4 La Regence (1982)

Unread post by CHVL » Sun Sep 12, 2021 2:39 pm

The Sandy Electronics TSB4 La Regence is fundamentally different from the France Double R ORIGINAL La Règence (1981)
The 2 versions (TSB4 Sandy, and France Double R) of La Regence are different on:
- their wood manufacture
- their legends: German versus French
- their electronics
- their program version of the Richard Lang's Cyrus (and maybe not even the Cyrus program during the first Tournament: "According to Kevin O’Connell, a La Regence program already played the ACM 1981 Blitz tournament still running on an Osborne Z80 based computer, beating Cray Blitz and Chess 4.5, and only losing from Belle [4]. However, the Philidor Software program which played the ACM 1981 main tournament was called Philidor with David Broughton and Mark Taylor mentioned as authors in the booklet" : PHILIDOR, authors: Broughton, Taylor (at site), Levy, Johnson on a Z-80 based microcomputer Assembly 28 Kb, 16 Kb 4,000 moves 400 nodes/seconde. "... and likely more related to Vega rather than Cyrus. A dedicated La Regence prototype played the European MCC 1982, and became unlucky runner up behind Advance 2.4 after losing in the final round by it's own stablemate Philidor". Obviously, the program of Lang was made by R. Lang for the count of Philidor Company owned by Levy and O'Connell, Still it was a different software version. The first version was more powerful than the second explaining the defeat of La Regence at the European MCC of 1982. The consequence was immediate and pushed the bankruptcy of the French company.

The following two Sandy Electronics TSB4 La Regence have differences.

The electronic of these 2 Sandy Electronics TSB4 could be different, but I didn't open them (?)
The legends on the left and on the right are different.
