Re: All Bug HP-41C Message #2 Posted by STeve on 11 July 2000, 7:50 a.m., in response to message #1 by Hugo
To test if you have an "all bug" 41 do this:
49
Sto 01
Sf Ind 01
If the BAT comes on then you have bug... um... 3. That one was fixed _real_ quick, and having it pretty much means you have the lot!
Bug 2 allows you to Rcl Ind nn and Sto Ind nn registers that are larger than the number you have (e.g. 800). Playing with this (especially sto) can be a little exciting :-)
If your HP41's serial number is 1926 to 1940 then you probably have all bugs. 1936 to 1952 had bug 3 removed (note that there is some overlap). 1951 to 2034 has 1, 2, & 4 removed. Finally 2035 onward have 5 7 and 8 fixed.
The overlap is there because HP didn't just switch over immediatly to a new rom version. it took time for the parts to "filter through"
