    I'm not quite sure I understand what you want. Do you want to use an ST keyboard (or computer) emulating a PS/2 and/or USB keyboard? Or you want to use a PS/2 and/or USB keyboard with the ST computer?

     

    All of the possibilities are feasible, but none of them are trivial. If I understand correctly, you want the former (an ST keyboard, or computer) emulating a PS/2 or USB keyboard.

     

    Emulating a PS/2 keyboard shouldn't be too difficult, but it changes a lot if you would be using the ST keyboard alone (which would require scanning the matrix), the ST keyboard interface (which would require understanting and parsing the ST IKBD interface), or just the whole computer.

     

    Emulating an USB keyboard is a bit more difficult, but the main issue here is that you need a microcontroller with built-in USB device controller. There are plenty of those, but USB support is usually not present at the lower end of PIC or AVR lines.

     

    i'm converting an st to an atom based computer the only snag i have is that i want to keep the original keyboard and functionality so all i'm keeping is the keyboard so usb would be ideal...but ps2 i can cope with too.

    just found one of these in my loft i know i used to have a tape deck for it but it seems to be missing along with its power supply ...by the way what cartridges work with this since i noticed it has a top loading cartridge slot

    a parallel solution wouldn't be beneficial as all i'm using is the original keyboard but it does offer one method for playing with my other ST :), I've just contacted Individual Computers hopefully they'll reply.

    i can code a little what sort of microcontroller would i need is it similar to that coin- op board i linked to in my original post? and i'm in the uk here and really glad to find theres life in the atari world. If you could link me to some plausible controllers i would be very grateful i've been looking for possible solutions for ages even changing the backing of the keyboard with an old usb one but some of the keys are different , so enevitably that failed.

     

    After i've got this sorted its whether to modify the orignal atari power supply (depending on how powerful it is) or stripping a pc one.

     

    Thanks for the help

    Hi i'm working on a project to turn on of my old Atari 520 STe 's into an mini - itx emulator machine to make it more useful since i have two of them anyway (I can offer any of the innards as i don't need them this particular one is unmodified.)

     

    My main stumbling point at the minute is the power supply and the keyboard. the keyboard being the biggest issue as i'm aiming to convert it to either a ps2 or usb connection and to do either as far as i know i need another controller chip and was wondering whether you think one of these would do the trick ;

    and this model VIP-312-128 since if I've counted correctly theres 95 keys on the Atari st keyboard.

     

    i know its not strictly Atari on the other hand has anyone seen a scsi cable that connects two Atari hard drives together as i have two one from each atari but can currently only connect one at a time due to the terminated connections.

     

    thanks any advice idea's or if interested in the gutted parts feel free :) got tons of st floppy disks to go through and need to work out what i did with the old hand scanner for it :)
