The first person I knew that owned one of those HP's was a friend who was an engineering major.
I remember there was a transition period when some folks had them and others couldn't afford them. The question that arose was
regarding exams and whether it was fair to the slide rule crowd to write tests that were easier for the calculator owners. Naturally,
that problem didn't last long. Since I didn't do engineering, I didn't buy my first calculator until after I was out of school and they
were cheaper. Finally, I was able to balance my check book!
 
I had an HP-55 and HP-67 in high school (HP-65 was the first programmable calculator with a card reader, HP-67 was the 2nd generation). If you check eBay, they go for about the same price now as they did back in 1975-77. Or, download an app to your phone for the same look if you're nostalgic or prefer the layout of your old college calculator.

Couple of additional eBay purchases. First is a Boston gear tooth gauge. Goes from 6 - 80 diametral pitch. Paid $50.

I've been watching a Shars 06IRA60 boring bar set on eBay for years. Just couldn't bring myself to spend $135 for a boring bar and 10 06IRA60 inserts. Found an alternative.

Did a search for 06IRA60 and found a couple of listings from eBay seller "cngx2016" for a what looks like the same thing minus the case in the Shars offering. These are $12 delivered for the boring bar and $16 delivered for the 10 inserts for one each. Bought two sets so got a little discount on shipping or $26 each. Yeah, don't plan on digging through the swarf to find one of these inserts if you drop it. Same for the boring bar set screw. These thread to a max depth of 1/2", minimum bore of 1/4", 16-48 tpi.

Thanks for looking.

Not a purchase , but I acquired a 9" South Bend lathe today . Needs a bit of polishing up and a gib , but none the less , it's a lathe and it was free ! :encourage: We moved the Clausing Colchester in last night and the SB had to go .
 
So after investigating a bit , this lathe looks to be a South Bend 9A with a undermount motor . I'll post pictures when it comes home . I'll be looking for info on it here I'm sure .
 
My new to me Industro-Lite horizontal/vertical milling machine.
A gift from a friend.
I finally found some time to get to know this very capable mill.
I’ll make chips today.
Serial number 178
