IBM are insane, the build quality of the Model F is even more insane compared to Model M PS/2 ones... These fkers weight about 4 kilos lmao. Even the original box for them is well made, you can tell when you touch one, all made in UK too, not China, no Mexico... There are USA made models, but so far i had few made in USA Model Ms, could not see difference to the UK made ones... The Model M13 stealth black that i still look for (same with the Model M Gen 0 metal badge industrial gray), was made by Maxi Switch Mexico, that sucks, as their build quality is not very good sadly, but still the keyboard is all in black Model M, as is annoying that 97% of all vintage well made keyboards such as NorthGate Omnikey, IBM F/M even Beam springs, Zenith Data Systems, NMB Tech, Cherry and others, are all white or elephant horn color....
Only will need to replace the caps, as i dont like these letters much, also not sure if these are QWERTY or other standard. The layout is also annoying of the Model F, but once i get my hands on the Tinkerboy DIN 45322 to USB converter i will be able to use them on normal PC, but i think the layout will piss me off prob, is the one thing that did always annoy me about Model Fs, Model M was the the thing that did bring the 101 standard we are using ever since, and XT design is crap.. But still Model F is the ultimate keyboard even with that B$...
Also Model M122, also build very well, not as good as the F, but in league of its own...
Also few Model M PS/2, always fun to see these. I still like my NMB RT101+ more then Model F or M, but the IBM keyboards also have special place in my collection too....
Now left to finds premium ALPS keyboard such as NorthGate Omnikey or at least Zenith ones...
