RJ11 Space invader conversion?

[chiptea]

Hi,
I've noticed that there are some space invader keyboards for sale on Cindy's website that have an RJ11 cable on them. Has anyone here bought one, or had experience converting them to something readable via teensy? I don't have much experience in this area, and help would be much appreciated.

Here is a link to the board for reference:

Would this be like a dolch? As in it's not a protocol conversion so it can be adapted with a little wire and a ps/2 male end? I'm thinking no since it's a terminal board.

Fohat should be incoming shortly... He had one like this, but hasn't had luck getting it to work with a modern PC, last I'd heard.

andrewjoy and I got ours to work easily. Open it up and you'll find the end of the RJ11 cable labeled clearly: power, ground, data clock. I don't have the link to that thread handy - search around and you may find it.

fohat has a slightly different one.

An RJ11 cable tells you absolutely nothing about the underlying protocol of the board.

Great! So it should be easily done with a teensy? What protocol is it running? I'll look around for the thread a little later as I'm busy. Still, thanks for the help.

Mine was Televideo branded and it did not look like that one, either.

There were a few available NIB and one of the more knowledgeable Geehkhackers on the West Coast (I can't remember who) notified a few of us, including Dorkvader, who is usually pretty good with these things.

But nobody has ever figured out how to get one of these working, as far as I know.

I bought this ANSI space invaders keyboard from Cindy and it is native PS/2. As XMIT said, on the inside, the RJ11 cable is removeable using a 6 pin header. Each pin on the header is clearly labeled; VCC, GND, CLK, DATA. It should be simple to hook up a teensy. I have been meaning to post some pictures of this board. It also has unusual stabilizer wires for a space invaders board...probably the best.

Other RJ11 boards are probably not PS/2. Most Televideo boards are ASCII and not really convertable in a useful sense. They send the ASCII character code of the key pressed. They do not have press and release events and some keys, like Esc do not send individual codes when pressed but instead send a second byte when pressed along with another key (i.e. Esc +A) sends two bytes.

Yep, I remember this now. I think I suggested a complete controller replacement as a possible retrofit for the ANSI boards but didn't have a chance to take a closer look at the PCB. If rows and columns are wired to the controller then something like Soarer's Controller could work pretty well here.

Press and release events are really important on a modern system for using multiple modifiers, for NKRO, for gaming, etc.

Yes..here was the previous thread:
