hi all, i have a small collection of old HP calculators, with the hp 71b being my favourite. as a watchmaker i thought it might be a good idea to add a digital clock HP 59309A to my collection. but this cost my quite a few hours of sleep as i encountered an unexpectd problem that i can't solve. i have already posted this problem to the forum of the HP-Museum, but unfortunately i could not get a solution. so i thought i should try it here. i have an hp 71b connected via HP-IL (version 1B) to an hp 82169C HP-IL/HP-IB interface (DEVID$ is HP82169A, though). an HP digital clock HP59309A is connected to the HP-IB interface.
the IL/IB interface is in translator mode, hp-il address 3. the clock is addressable, address is 11. i can control the clock (set time, stop etc.) without problem (e.g. OUTPUT 11;"R" resets the clock). but i am not able to read from the clock. my latest attempt to read from the clock looked like this: RESET HPIL RESTORE IO SEND TALK11 (ADDRESSED light of the clock is now permanently on) ENTER :11 USING "#,9A";D$ (i also tried 10A, 11A etc. and ENTER LOOP) then the loop freezes, the hp71 does not respond to pressed keys, and the T/R light on the interface and the ADDRESSED light on the clock are permanently on. to continue i have to reset the hp-il interface. any help to solve this mistery would be much appreciated! thanks, hans _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
