Thread: hp-41cx / NoV-64d / Hepax XF multi-function

[Diego Diaz]

Hi Kees Jan, all,

As confirmed previously, the XF function is fully operative on NoV-64d.

Also, your HEPRAM erasing procedure works as expected, since you get HEPAX RAM on pages 8-B.

It will be good to RUN HEPROOM (should return 2,610) after erasing and power cycle. And remember you need to power cycle after erasing every chip for the HEPAX to build the FILE SYS.

At this point, it may help to check if you got the same problem when running this program with a different HEPAX RAM chip.

Please, place 001, 002 or 003 into H'4100 and test your program again.

It would be the first case but it is indeed possible that chip 000 is faulty.

Look forward to reading from you.

Best wishes.

Diego.
