If you want to try MacHackVI, I've compiled a barebones bootable TOPS10 7.03 disk.
(Be warned, in unpackes to 315 MB.)

simh (pdp10) binaries for osx (x86_64) and windows are also included.
consult start.txt to get it running, and chess_how.txt to play.

have fun

Mac Hack VI incorporated a table of opening positions with selected replies. The opening book was compiled by two MIT students, Larry Kaufman, a chess master and top rated U. S. Junior player, and Alan Baisley a chess expert. It is noteworthy that Larry Kaufman started his computer chess career over 50 years ago as team member of Mac Hack! Quote from Oral History of Richard Greenblatt:

And it was compacted pretty efficiently. And you know, there was a – by later standards it wasn't so big, but at the time it was pretty good sized. I don't know I think it was probably 8,000 or 10,000 moves in there. He – Kaufman spent quite a while doing it. Of course, a number of the moves, you know, would – the game would just play it. There was very little chance of it actually staying in the book. You know, the – but I think Kaufman did a good job and he did – we did perceive some of the – well of course, one of the basic things about computer programs, really to the present day, is that they're very tactical. It's much easier for them to see that the tactics than the strategy. So what's called a closed position is hard for a computer. That's where all the pieces are blocking each other and it's very long maneuvering. Whereas, an open position which is sort of tactical combinations is much more to the computer's liking. So therefore, when designing the opening book, you want to kind of play offbeat and kind of unbalanced type openings that tend to lead to these closed position – open positions, which are then good for the computer. And so we realized that and you know, I think Kaufman did a fairly good job of ...

War es nicht ein MacHack-Computer, gegen den Bobby Fischer einst eine kleine Miniserie hingelegt hatte (3:0), eine Serie, die seinen Fans Hoffnung gemacht hatte, dass er doch wieder zum organisierten Turnierschach zurückfände?

Gruß!

Ja, und auch gegen andere..

BTW. The Mac Hack VI above seems to be an early version of 1970.

Hallo Ihr Experten,
danke für das interessante Programm.

Könnte mir jemand verständlich erklären, wie ich es zum Laufen bringe unter Windoof 11?

Vielen Dank und ein schönes Wochenende
Beste Grüße

Ich bin schon ein Weilchen nicht mehr auf Windows..

Mit command-line / terminal ins Verzeichnis MacHackVI wechseln (cd ..) und pdp10.exe starten. Dann die weiteren paar Schritte im start.txt befolgen. Sollte ganz einfach sein.. So siehts dann aus (Fett sind Einzugebendes. ^C ist CTRL-C).

Hoffe damit klappts.

Beenden mit CTRL-E, dann CTRL-C.

PS. MacHack benötigt die (englische) deskriptive Notation!

DEMO

Hoffentlich hilft das...
MfG
Tibono

Ist ja schwieriger als Schach spielen ;-)
