Ahem... also Start+Reset to enter the U1MB BIOS menu if the user configures the alt BIOS that way. ;) And Select+Reset (again, optionally) to perform an OS reboot (an option also present in some patched operating systems, IIRC).

 

You can be pretty sure Option+Reset will be used by something as well, and/or any combination of all three console keys (Start+Select+Reset, for instance) by something somewhere.

Thanks guys :)

So we'll assume any possible combination of the Console keys and Reset.

and shift+key control+key etc.  combination can be used with a console or console keys... help with select start option, shift+ key + console(s).. don't forget MyBIOS/MyIDE key combos, or Sparta's assignable reset utility for non reset programs... plenty of 3 key or more salutes today...

I'm really looking for 2 key combos that include Reset. All of the other usual SHIFT and/or CTRL combos, or Console and an alphanumeric key should work just fine as it is now sent by TK. So that probably restricts us to non-alphanumeric keys+Reset, since pressing an alpha would start printing that on screen prior to pressing Reset, not the most desirable action.

 

So that seems to limit us to: SHIFT, CONSOLE, and INVERSE (maybe INVERSE in combo with SHIFT and/or CTRL).

 

I don't believe CTRL can be detected in combination with Reset all by itself since it needs to modify a standard key to be seen, so that should rule it out.

 

Am I missing anything  :?

Add HELP to the list, but I think it's implicitly included anyway (also SHIFT+HELP, CTRL+HELP, and SHIFT+CTRL+HELP) since it's used by U1MB. :)

 

And no: CTRL only exists as a modifier key and does not register on its own.

Is it possible to buy this ready-made? I don't like soldering...

New TK-II Boards Coming

 

Soon there will be brand new board versions of the TK-II for both standard A8 systems as well as the XE Game System and/or 7800 XM. The existing designs will be moved into an archive section, and these new ones will be the current offering. Expect to see these new designs released and published on my website later this month, or early May of 2018. I still need to purchase some sample boards to test before commiting.
 
So here's the new TK-II family.
 
New Smaller XE Game Systems External Plug-In Board (also compatible with 7800 XM).

Uses Dsub15 female solder cup connector edge connected to board (needs metal shroud removed and plastic halves glued together).

Smaller Remake of original Pokey Piggyback Version now with integral ICSP programming connection.

Reverse Pokey Piggyback Version (better fit in XL/XE allowing more clearance under keyboard).
 
TK-II-PB-R_top.png

PS/2 Ribbon Cable Connected Interface Board for Pokey Piggyback Boards (same as previous with slight revision on silkscreen).
 
TK-II_Intfc_top.png

The Pokey Piggyback boards require a thinner material due to the use of 'standard' machine pin sockets top and bottom, with the stacked bottom socket providing clearance for the PIC16F1847 chip mounted on the backside (although for very low profile requirements, substituting a machine socket on the A8 motherboard with the center cross bars removed instead will allow a very low ceiling).

 

All boards now automatically support up to two simultaneous PS/2 keyboards either through the extra connector on the TK Interface board, or via a dual PS/2 keyboard cable. No mods required.

 

Note: The board renders on this post are provided through an on-line gerber viewer, and sometimes ground planes are either not shown, or produced inaccurately (missing thermal reliefs). The final product produced from the gerbers will be correct in all details.
