Re: HP 9114A floppy drive Message #7 Posted by Tony Duell on 26 Nov 2004, 7:20 a.m., in response to message #1 by David Osborne
There's a schematic of the battery pack (both versions), along with the rest of the 9114A and many other HP calculators and peripherals on the HPCC schematics CD-ROM.
There's a picofuse in these battery packs on the PCB, connected between the battery +ve terminal and the output. It looks like a resistor, and is normally rated at 2A (although I have seen 5A ones that don't look like they've ever been replaced. I would check this first.
