I'm trying to save and restore ASCII files from extended memory to diskettes. Each time I try, the drive spins for a few seconds and I get a NO DRIVE message on the 41. I've tried taking everything out of the loop except the 41 and the 9114, removing all modules except the XMEM/XFUNC module, and doing an ON-BKSP reset. It doesn't make any difference. Once in a while SAVEAS will appear to work (especially if I make the diskette file a couple of registers larger than the XMEM file), but GETAS always fails no matter what the file sizes are. Everything else I do with the calculator and the drive (NEWM, WRTA, READA, WRTP, READP, SEC, UNSEC, DIR, PURGE, VERIFY, etc.) works perfectly, as do the HP-IL/RS232 interface and 82162A printer I usually have connected to the HP-IL.
Does anyone have any idea what could be causing this? I've gone half blind digging through old issues of "PPC Journal," "CHHU Chronicle" and "HPX Exchange" looking for bug reports about this, but haven't found anything yet. Any suggestions would be greatly appreciated.
