ATI KB-3500, Apple II Plus Clone & other questions

Hi Everyone,

Since looking up my first mechanical keyboard on the DT wiki several months ago, I've fallen rapidly down the slippery slope of hunting for, cleaning up and using old keyboards. Recently, I found several old boards, and thought I would share with the fantastic community here, and ask some questions/look for info. I apologise in advance if my finds are a bit mundane compared to some of the other posts here, but I feel like there's a bit too much to fit in an existing thread. I've posted some photos here, and the rest in linked albums, to avoid it being too long.

First is this Apple II+ clone. I have essentially no information on it, other than it uses the standard apple II keyboard connector, and sends the same 7-bit ASCII codes. I have got it to function using a Teensy, and it works well. However, I do not know what the switches are, despite spending ages going through the wiki. They are cross mount, linear, pretty smooth, and have quite short, abrupt travel. I'm sure someone recognises them, or maybe even the system the board came from. Note that it is as I got it, and the handwiring was done previously. Full Album:

The next is the ATI KB-3500 model F XT clone. The 'ATI' is in the IBM font, and the cable says 'Taiwan'. The Apple logo appears to be from a Disk II. I posted this in the 'Identify' thread, but since then I have realised that the switches are Monogram SMK derivative series, as the monogram can be seen through the holes in the PCB. The spacebar uses a beige top that is not in the wiki. Additionally, the they do not appear to be Cherry MX mount. As it is a clone, I don't expect too much info, however any hints to the interface would be seriously appreciated, as would help with cleaning the switches. Full Album:

The Macally MK 96 doesn't have a wiki page, but I thought I'd share mine, as it has GA white Alps clones, which I haven't seen mentioned in conjunction with this board. The switches are scratchy and bind badly and the caps are worn pad printing. Layout is similar to the M0110A. Album:

Another board without a wiki page, the Qtronix QX201. This is a bit of a weird one, and I believe that it has Cherry MX Pale Blue, although I might be completely wrong. Album:

I also found an Ortek MCK-101 with clicky white APC switches (although some switches seem do be an unbranded alps clone). I think this is fairly unremarkable, but the exact config is not in the wiki, so I thought I'd document it. This board has a cut cable, and I was wondering if anyone with one of these can tell me what the 5th wire is in the cable, as I believe it uses a standard AT/din5 connector with 4 connected pins?

Finally, here's what looks like an RJ11 version of the Datadesk Mac 101 that I haven't seen much about elsewhere,. It has SMK inverse white tactile. I assume this is an aftermarket alternative to the M0110/A for the Macintosh Plus. Ablum:

The Apple II+ clone has Futaba sealed switches. Looks like the Qtronix QX201 indeed has pale blue Cherry MX. That's a really nice batch :D

Thanks!. I thought the II+ was something Futaba, because the latching switch looks to be a Futaba Linear Lock, but I couldn't find one that matched. They're pretty decent switches, surprisingly smooth for how dirty they look, although they're pretty heavy.

I didn't even know pale blue existed until recently, and I guessed they were a tactile or even linear switch before pulling a cap. They are certainly more interesting to regular blues, and I find them a lot more fun to use.
