OSI 600D replica keycaps

[andrewh]

I can see several threads relating to sets of keycaps for the 600D replica. Does anyone have a set to sell? Bonus points if you've got a Cherry locking keyswitch!

Cherry hasn't made the locking key as a production item in some time. There are many other retro-computer groups that would like them too, but ..

i read a few years back that one group had contacted them and asked if it was possible to buy a bunch of them and Cherry said "Sure, as long as by 'bunch' you means 500,000 or more." I think that ended the conversation.

[andrewh]

Yes, I saw that. I'm much more interested in the keycap set. The locking key is a nice-to-have.

The latchingd keys, futaba and Cherry MX, are very hard to come by. But it's not hard to whip up a "soft shiftlock" functionality. I have a circuit that adds this, if you are interested, along with a 3-second delay for RESET, and power-on RESET, intended for the 542 keyboard or early 600 boards, that don't have either capability, but you could also add it to a later 600D or 542C machine.

Yes please, that would be great.

The schematic is here

I have made some PCBs for this circuit and would be happy to send you one.

Thanks.

I've mainly given up trying to find keycaps, so I'll buy a standard set and mod the rest. But where do I find an 8u spacebar?

Sorry, I missed it. I have replied directly.
