help me to get an unknown vintage alps keyboard to work!
Posted: 11 Sep 2019, 18:32
hey guys,
i recently bought this unknown cream alps keyboard (maybe dampened creams, idk really) from tentator (huge thanks to you!!)
it blew me away. never had any keyboard with vintage alps. the prestine mint condition, the absolutely beautiful sound and crisp typing feel. i immediately fell in love.
(apple font on led cover?)
so heres the problem: i cant figure out how to get this thing to work. theres no brand, no useful serialnumbers. and the more i try to figure out what it is, the more weird it gets (atleast for me).
12V 150mA?
it has two ps2 inputs, one on each side. both of them with a keyboard symbol (i guess its that).
so my young innocent heart believed i could get it to work only by connecting it via the proper cable.
(tried both sides)
cable fits in perfectly - good thing! started my machine (i should mention its a modern windows pc, but with native ps2 input), keyboard starts to beep (it has some kind of inbuild speaker), lights flashing and that was it.
lights stuck in a weird order, beep is gone. no signals will be transmitted to my computer. it will do that on every reboot of the machine.
i figured maybe its the wrong protocol and i opened her up. maybe im lucky and i could find some kind of switch or jumper. nothing.
controller is a philips 80c51bh-3, tried to find some useful infos but turns out these things can process a lot of stuff so idk.
i dont have any ideas and as you can see im really a newbie in terms of this stuff.
if you have any ideas please let me know. thank you so much in advance.
