Title: IBM Model F (5155 Portable)
Post by: ebacho on Fri, 20 December 2013, 01:23:13
http://www.ebay.com/itm/IBM-5155-Keyboard-For-Portable-Computer-FREE-SHIPPING-/321268058073

$44 shipped, clickykeyboards info page for a similar keyboard says it's XT protocol so it can be hooked up to a Soarer (http://www.clickykeyboards.com/index.cfm/fa/items.main/parentcat/11066/subcatid/0/id/571248)

just a little caution here

that's a phone connector so you need to build your own adapter on top of the soarer adapter you already have to do. More fine work with teeny weeny wires!

a normal xt, you can just hook up a standard AT to ps2 cable adapter

and of course, since it is portable, it dispenses with the normal XT's advantage, which is solidity and metal plates. that thing has no metal plates if I am not mistaken. I have one that I never got around to making an adapter for and it is boxed up somewhere. if you just jump in and buy rashly, might end up like my boxed up somewhere 5155 keyboard.

I've got a couple of these. I love them. I don't understand why people hesitate when they're cheap because they're much rarer than the other XT keyboards. Sure, they don't have metal plates, but that makes them nice and light. I plan on converting one to use when travelling and the lightness is a bonus. The case is still solid (feels like wood) and doesn't flex. It's clickier than my AT Model F.

There's the problem with the connector, but I'll be looking for a phone-style jack box which I'll install the teensy in to make a convenient plug-in adapter.

mr_a500, can you take photos of the adapter making process and show us when you're done? I would love to do the same for mine, which as mentioned above is still boxed up and never used.

Yes, I'll do that as soon as I get the parts. (probably next month - because of the extremely slow shipping to Canada)

I noticed the 5155 keyboard is gone. Somebody didn't hesitate.  ;)

well, whoever didn't hesitate, he did hesitate to thank the OP I guess!  :eek:

And don't hesitate to make a nice adapter. I've been putting this off for like forever because of my unfamiliarity with the phone connector thingy.

hell, while you're at it, do you think making a wireless bluetoothy thingy would work? you're going to use this with your laptop or tablet, right?

Mmmm... bluetoothy thingy.. that sounds like an interesting idea - but what about the power supply?

I'm not technically skilled, but hey, this website is crammed with technical geniuses! You'll figure it out, right?  :eek:

btw i have been reading about charging batteries using wireless adapters. You can do that with the latest Nokia or something. Surely some geek here will be happy to help create a wireless keyboard that can draw power just like that?

How are the barrels (chimneys) handled if there is no plate? Is it a one-piece barrel frame like the M, or do they mount in a plastic plate?

I posted a "RJ45" (8P8C) connector/adapter that I fashioned myself in Soarer's thread #901. Be sure you get a real full ethernet cable and jack, the common ones you see do not have the right pins active.

I've never opened the 5155 keyboard case. There are no screws. You need to un-snap the top piece and I am too worried about damaging the clips to attempt it. (looks fragile)

The connector on the 5155 is RJ11, not RJ45.

See http://www.brimstudio.org/2013/10/ibm-model-f-restore/ (http://www.brimstudio.org/2013/10/ibm-model-f-restore/) for pictures of the insides.

Seems like it has a metal plate though.

Hey, thanks for that link! That pin-out photo will come in handy.

That is one hell of a filthy keyboard. Mine are pristine in comparison.

Search LZ's site, he did an MX-Mini with bluetooth. He bought a kit somewhere.

That keyboard is not "dirty" from what I have seen, I would call it "about average" in cleanliness for an ebay F.

The internal plate looks just like the "black" steel plates in every other F I have seen.

Ha. I got distracted by "beam spring mania". But now I've got another 5155 in the mail and I guarantee* that it'll be converted soon.

No, no - I didn't buy the one listed in this thread. I bought one a couple weeks ago.

Now I remember why I didn't convert one earlier! PJRC (Teensy maker) doesn't take PayPal. That's what screwed me up. (not a problem now)

Cool! I'm looking forward to this.

Personally, I prefer this model to the "normal" XT. The XT isn't bad though.

Eventually I'll get one of the XT layout Kbs with the huge case and triple stage feet and put XT guts in it for kicks.

It's a nice look for a board with an XT style

Why bother putting XT guts in it? My controller code works with bigfoot, and it scans at 1000Hz - it's the fastest IBM around :cool:
