Fred,
That's been there for a while. It is aimed at babies swallowing coin
batteries of all sorts. Mine was pure stupidity. I had spent the whole
weekend working on and rebuilding the
All of them are for various hard drives. None floppy of any sort.
The first 4, 2840, 34, 21, and 09 all look like ones I'd use on a
Western Dynex either 5mb or 10mb (capacity) drive. 100tpi or 200tpi.
The others are progressively higher density, someone else may recognize
them. Epay
That would make sense, as I picked up 3 RK05 drives in the lot.
Good to know what they go to now, perhaps i can sell some off to others
that need them, and offset the cost of the pickup
Thank you for the quick reply

Or in my case, one of the dogs. I had one of those tiny chips slip

then it was "only" 16GB...

Tony, I don't recall what became of the AT with 486 replacement
