Yeah that would be the find...I've never seen one though.

I also sort of feel like the XT is under-appreciated as compared with the more exotic Model F variants. I mean... The XT is super heavy duty, it's not too huge (the combined nav and number keys are pretty efficient), and the eccentric layout is not as hard to deal with as it may first appear. And as you noted, they aren't hard to find.

I've got to say, however, that the new reproduction F77 looks pretty close to my ideal keyboard layout. In fact, I'd say the Ultra Compact F77 with the aluminum case is about as modern as keyboard design gets.

I have to disagree. When it first came out, the XT's layout's right third reeked of poor design. I was a teenager and I found it pretty bad, so much that I still remember how much of an improvement the "enhanced keyboard"'s layout was. So, why use the XT layout when the much better "normal" one is around? (besides the key feel itself, that is)

IMHO, YMMV, of course.

Looks like a 3277 with only the 60% block.Wouldn't be too hard to make one since the caps already exist. Just cut the plate and modify Emdude's capsense PCB to only have that section and you'd be good to go. Just needs a custom case :)

That's basically recreating the entire beamspring less the switch.

We should do it. Create the B62 (beamspring 62)! Custom plates, case, PCB, xwhatsit.

Why not go fully over the top with a B122 "beamship"? (or "battlestar", while we're at it)

Suppose you could; but you would need more donor switches (IE, less total boards could be built) [unless we go all Ellipse and recreate new Beamspring switches].

There is a problem with AT layout; the backspace and Esc are adjacent, for several times, I hit the Esc key by accident and lost a whole page of text I'd keyed in, which's exasperating. Now, I've got Esc and Sys Req key swopped.

My personal endgame model F would be 122 version in battlecruiser housing (chyros terminology). With some additions. One day...

That's the thing with IBMs for me, they are never quite perfect and yet they are the best I have found.
I have an XT at home and model M at work.

The XT has a hideous layout but a very compact form factor and that retro look that I just love, clicky feel and force is absolutely spot on for me, here's a photo of mine: keyboards-f2/ibm-xt-almost-ended-my-game-t17664.html

The AT is bigger than the XT, making me wonder, well, I might just use a model M and spare me all the spacebar modding. In general there's something about the AT form factor that just doesn't appeal to me.

122 battleship, I could never have such a beast occupy the whole desk.

Model M, I find it a bit too stiff, like other members have reported as well, I like it, hate the numpad and the 90s look of its case, but in general for now is the best I could find on a budget.

Definitely an F77 would be the end game.

right now my soft modded(sharpkey + auto hotkey) f AT, but i do want to see what I can do with the XT and auto hotkey too! when i get my f122 it'll probably be my main, if i like it even half as much as my gf does her unicomp model m 122.

also the hhkb layout on the f77 from elipse thats coming may be enough to usurp the 122 for me

I like the IBM Model F AT the best as it is much more compact and and has normal key sizing plus can be easily modified to a modern layout all that needs to be done is some custom key remapping and new keycaps or some relegendable keycaps. I know some really like the a dedicated nav cluster but for me using the num pad is no issue. Below is my modernised IBM Model F AT I use as my daily driver. The layout I have set gives me F11 F12 and all the media keys the image looks blurry in the attachment but it is actually not just do open the and it is perfectly clear. This image was posted in a different thread but thought it would be more appropriate here.

Lately it's been the F AT for me too, since it has the closest layout to a standard TKL once modded.

Wow that's quite the keycap set you got there also nice ISO mod have not seen more than one other ISO AT. I also like the TKL layout you have but I could never get used to having half my f keys on one side and the rest on the other side also I saw you got a model m space bar installed my I ask how hard that mod was to do. Either way looks great well done.

Thanks! The alphas, arrows, and weird legends came from an Impressa (a.k.a. Wheelwriter) typewriter; num row, homing keys, guillemets, accents, symbols, Enter and function keys are from the Unicomp set I originally ordered for this board.

For your information: I set the upper-leftmost key to Super/Windows and the lower-rightmost one to Menu. The blanks do nothing for the moment. This effectively gives me all the keys from a TKL layout with no layering required.

I don't completely touch type the F-keys so their displacement isn't as big a deal as I thought at first, though I still reach for the top of the board on occasion and likely will keep doing so since this is one of many boards I use regularly.

For the space bar, take a look at my earlier write-up in this thread. Those pads send Set 3 codes, by the way. I trimmed the Alt caps I had, but in retrospect 1.25u caps with proper legends from Unicomp would probably look better.
