modern model M’s do they live up to the hype?

Unicomp Keyboards used to be rather derided due to declining quality resulting from aging manufacturing tooling, making them a mere shadow of the Keyboard IBM made. That being said, their “New Model M” uses new tooling. The situation seems to have improved quite a bit on this new model as a result. That being said, at $125 I find the New Model M rather pricey for what they are: a basic keyboard with limited customization and mere 2-key rollover. If you really want buckling springs and want them brand new, it is the way to go, otherwise consider buying an original Model M used or buying a regular mechanical keyboard with clicky switches.
i agree it’s a little pricey for what you get but my fingers only want leaf springs but i can confirm that the new model m has 6 key rollover. the standard spec for USB keyboards. NKRO would be nice but I also heard there would be issues with bios not seeing the keyboard on older systems. I have not verified that though.
They’re not 6KRO. All Model Ms are membrane keyboards, which make implanting diodes difficult, so they’re fundamentally 2KRO.
to clarify this is the new model m from unicomp not an OG model m. I have the new model m right in front of me and can confirm it’s 6KRO
I also have a New Model M. It uses the same matrix Unicomp has used for years with their Ultra Classic and EnduraPro keyboards. As such, you should be able to observe 2KRO by pressing any 3 WASD keys together (and see my matrix simulator to find more examples).
I don’t mean to sound like an arsehole, but it’s not a matter of debate; a conductive membrane using a key-matrix is practically limited to 2KRO. You’d either need to stick diodes in (which is harder and not cost-effective to do with membranes versus PCBs) to prevent back current from ghosting keys, or you’d need dedicated traces for each switch position instead of using a matrix (which is costly in traces and the design of controller you’d need for that). Because neither is a practical option, the controller must block keys susceptible to ghosting because not sending all intended keys is preferable to reporting keys not even being pressed. In a key-matrix without diodes, 2 is the maximum number of any given keys guaranteed to be reliably sensed and reported together, thus Model Ms (like most membrane keyboards) are 2KRO. That doesn’t mean more keys can be pressed under certain situations - the matrix is like a table of traces, having columns and rows and what combinations are being used matters - but it doesn’t change that key rollover means the maximum guarantee across all keys and the number in this case is 2. Not the maximum possible key combination under any condition. I think that part is what confuses a lot of people (which is understandable, I’ve seen it misrepresented for marketing and used as a buzzword). But, Deskthority Wiki describes as such which is probably generally easier to understand:
2KRO is often used to describe a keyboard with blocking, and is meant to be read as “any combination of two keys are guaranteed to work, and some combinations of three or more keys will work, but others will not”.
I’d be surprised if this is not the case with your keyboard. With the Unicomp Mini M, they improved supported combinations by making the matrix larger (from 16x8 for New M to 16x12) and then using maths you can find out where in the matrix the most commonly used keys should go, but you can still observe 2KRO on a Mini M by trying to press any 3 arrow keys down.
Hm, must have googled that spec wrong, to be fair, they don’t list it on the product page.
agreed i can totally see how you came to that conclusion. i only mention it cause I thought the same thing but was surprised when I did the keyboard test. becase the old Ms only had 2 like you said.
I have that one too!!! Most excellent.
i picked up the Linux keycaps for the meta keys as well . Also can I ask you a question about your keyboard? Does your right menu key click like the others or is it liner with no spring?
It seems clicky like the other keys. I should get Linux caps too hah.
thanks it must be just mine that’s broken no big it’s not like it’s a key I care about or type much with that key.
That is unfortunate. I hardly ever use that key haha. Maybe Unicomp would fix it, have you asked them?
eh been to many years at this point i only noticed it a year after I got it since I almost never use that key. i was more curious if it was by design to not used a leaf spring on that key for just that key to cut costs or something.
I have been eyeing Unicomp’s Model M for a long, long time. But unable to justify the high shipping costs - it costs more than the keyboard to get it shipped to where I live!!
Though I won’t lose hope. :-)
I actually like the classic style more than the modern redesign. I just hope they don’t stop making the keyboard in that style by the time I buy it.
Do you use one? What are your thoughts about the keyboard?
Same here…Ordering one directly from Unicomp would be around $80 dollar in shipping costs alone
I wish they did a proper one with trackpoint, but apparently they only stick with that joystick.
The New Model M that came out a few years ago is pretty rock solid. I’ve had that, and a Mini-M and love them both.
Unicomp recently switched controllers to the Raspberry Pi RP2040. You can now flash them with QMK/VIAL and get a fully programmable Model M!
My daily driver since ~2016 has been an ISO layout Unicomp Model M (made in 2015), and i have currently no reason to replace it. One downside has been having to do the nut and bolt mod, because the plastic rivets holding the insides together have started to fail in large numbers after only a few years.
