Ktoid, a modified K80W for Altoid can

[Bill Shen]

Paul DB suggested another Altoid design but this time based on K80W.  It is called Ktoid.  This is K80W trimmed down to fit an Altoids can; on-board CF interface is replaced with plug-in SD card, so is the on-board RTC replaced with plug-in RTC module.  It is still a through-hole design in 4-layer pc board that barely fit.  It should run RomWBW but I can't test it yet because I'm waiting on the 32-pin PLCC socket for the 512K EPROM.

Wow, that's a snug fit! Bill, it must be frustrating not having that last component yet, the 32-pin PLCC, to verify construction.

I'm tempted to ask you for the Gerbers even if the board is untested as is. Nice thing with HTH construction is that it's always easy to reuse the chips for the next revision ;-) 

Thanks,

Paul

Hi Paul,
Here are schematic and gerber photoplots of rev0 Ktoid design.  Let me know if you've decided to order the pc boards, then I can send you pictorial assembly guide which are series of photos showing how the board is assembled step by step.
I should receive the PLCC32 fairly soon, probably this week.  I can also program the CPLD to do serial bootstrap without EPROM which is probably what I'll do while waiting for the PLCC32 socket.  This way I can run basic diagnostics to check out the hardware.
