Enough to make you cry.

Quote:If someone has powered this up using the mains psu, without a battery pack in the back, it's possible the internal chips may be toast, no? I thought the batteries had to be present to prevent the psu over-voltaging the circuitry. Certainly is the case with my 29C, which I've been very careful never to do this to.

Yes, you are right. It is toast and several days ago I sent the seller a note informing them of that and enclosing a screenshot from the HP25 manual (p.102) telling not to plug it in without a power supply. I suggested they might want to put that on their ad in the interests of being open in the listing.

They replied rather laconically "thanks for the info" and left the listing unchanged. To be fair, they do indicate what now happens when they turn it on while plugged in and say they are selling it for parts only. It does look like it would make a nice Woodstock LP.
