(HP32SII) Mastermind game based on HP41 version by Wouter Peters
Hi all,
starting from the Mastermind game for HP41 created by Wouter Peters and posted in HP Museum at the following link: https://www.hpmuseum.org/software/41/41master.htm I've translated and adapted it to HP32SII calculator. The resulting game is simpler due to the limited features of HP32SII with respect to HP41 (no sound, no printer, less memory, etc.) Below the program. Best regards, Davide M01 LBL M CK=B5C3 9 M02 CLVARS M03 SF 10 M04 FIX 0 M05 4 M06 STO J A01 LBL A CK=B6CF 19,5 A02 RANDOM A03 6 A04 * A05 IP A06 1 A07 + A08 RCL J A09 STO i A10 x<>y A11 STO (i) A12 DSE J A13 GTO A B01 LBL B CK=4F2F 53 B02 INPUT Z B03 1E4 B04 / B05 X^2 B06 XEQ Y B07 STO E B08 XEQ Y B09 STO F B10 XEQ Y B11 STO G B12 XEQ Y B13 STO H B14 RCL A B15 STO K B16 RCL B B17 STO L B18 RCL C B19 STO M B20 RCL D B21 STO N B22 5 B23 STO O B24 11 B25 STO P B26 4 B27 STO J B28 STO R B29 STO Q B30 STO Q C01 LBL C CK=9E91 22,5 C02 RCL O C03 STO i C04 RCL (i) C05 RCL P C06 STO i C07 x<>y C08 RCL (i) C09 X=Y?

Nice work! Mastermind is a great logic game and very suitable for coding. I'm not familiar with Hp32 code, but it looks like it wouldn't be too hard to bring it forward to other models such as Hp35s?
I used to play it as a board game in the '70's when it was very popular, but we dont seem to hear of it much these days. The link in the post above explains it. I wrote a program for it on a TI58, in 1979, and I still have it written out in pencil. Also, far more crazy, I built a machine to play it in 1977. It used a Sinclair Cambridge calculator (a basic 4function calc), wired with an umbilical cord of wires to supply power and engage each key. That went to a hardwired logic circuit of TTL chips to feed it key strokes in sequence and display the results. Pointless fun for a young nerd!

Yes, I think it should be translated without any particular issue also for other programmable calculators; the only "special" programming technique involved, I guess, it's the usage indirect store and recall functions, which on HP41 I've understood it can be done with any register while for example on HP32SII you can only do it with one specific register (the "i"), so you've to deal with this limitation (and the limited memory!). On the other side HP32SII has a built in Random number generator so I've been able a whole routine in the original version for HP41 with just command (1.5 byte instead of 10 bytes I guess). Yes, me too I've spent a lot of time playing with Mastermind tabletop version of the game with my family in my youth. As you said, I've never seen it around in these days, it's a pity since it's a really funny game. What you did with the Sinclair Cambridge I bet it has been a lot of fun too!
