Title: IBM Model F weights
Post by: chyros on Thu, 24 May 2018, 04:25:42

Hiya guys, I need some help preparing for a video I'm doing in a few weeks. Specifically, some weight measurements. Could people please provide me with a (fairly accurate) weight (digitally weighed, not including the weight of the cable, please) of the following Model F keyboards:

-5291 "Bigfoot" XT model
-3178 or 3101 "blue button"
-F104 "unsaver" keyboard
-4704 F50
-4704 F77

Thanks in advance, guys :D .

No-one? :(

Still need the weights of a F104 and an F77, please let me know a weight if you've got one!

I have an Unsaver but it is packed up for long-term storage, and I also modded it - ANSI, new foam, floss, and probably stuffed some padding in the case.

Still, probably not more than 50 grams additional.

5085 104 variant is 3474 grams. I'll see if I can weigh a 77 key later today, life's keeping me busier than usual.

Ha, now that's some serious measuring!

Well, the scale I was using only has readability of 0.5g, so there's some error margins there. It does measure up to 5kg though, so it's a decent scientific scale that I instead use for kitchen related purposes :D
