request: IBM Model F weights

[Chyros]

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 thanks Engicoder
-3178 or 3101 "blue button" thanks Engicoder
-F104 "unsaver" keyboard
-4704 F50 thanks Invisius
-4704 F77

Thanks in advance, guys .

I take it you already weighed the F122? And the keyboards you mention must be unrestored?

I would ask Ellipse directly for the F77 weight. I have never seen anyone else here who is confirmed to have actually owned one at any point, and perhaps his prototypes are going to be close enough in weight for your purposes if all else fails.

The XT, AT, F122, and F107 are notably absent from your list. One of these is clearly different from the others

The rest of the data I can provide myself . If possible the original weight, yes. If you only have modded examples, please state what mods you have done so I can use it if no other data becomes available. Hopefully I can get full, original data though.

5291 Bigfoot - 3.27 kg (3.10 kg w/out cable)
3178 BB, Numpad - 2.99 kg (2.79 kg w/out cable)
3178 BB, No Numpad - 2.87 kg (2.67 kg w/out cable)

[Engicoder]

Just noticed, you said no cable...can do that later if you like

Edit: Updated

[Iggy]

5291 - 3.27 kg
3178 - 2.87 kg

Both original including cable

How much in the imperial system is that?

[Engicoder]

The 5291 is about half a stone.

[Chyros]

5291 - 3.27 kg
3178 - 2.87 kg

Both original including cable

How much in the imperial system is that?

About 3 furlonged inchfeet.

Thanks Engicoder for the 5921 & 3178!

Just for kicks, you should list the weights of keyboards produced in UK in the metric system, of units made in USA in the Imperial system and of the models manufactured in Mexico in (any of) the old Spanish system(s). Kilograms vs. pounds&ounces vs. arrobas (or, if you want to be a real smart-ass, fanegas).

Oh yeah, if you could post the weight of that bigfoot (sans cable, just suspend it), that'd be great .

And thanks Invisius!

IBM model F
IBM part # 4176203
Date: 27 SEP 84

weight without cable: 3.06 kg

F107 = 4.54 kg = 10 lbs.

My letter scale goes to 10 lbs so it might be just slightly over 10lbs but less than 10.05 lbs. Sorry, can't remove the cord but it shouldn't make a difference if not stacked directly on top.

F107 heavyweight
