That month I mast have been slepping. I totally missed that month's issue of Popular Electronics[^]. Or maybe my parents had cut my allowance for some reason and I could not afford to buy it.

Look at the cover! Boards, LED address and data displays, a hex keyboard! That must be the Microprocessor Product Development System they mention in the headline above.

But why is it so familiar? The board on the right is the same as my Elf II's memory board. The one at the top is the Elf's I/O board. The board in the front has the Elf's hex keyboard , it's (slightly expanded) displays and new pushbuttons to control the processor modes instead of the Elf's toggle switches.

Buttons for processor modes? That already tells me what processor sits on the CPU board in the middle. Good choice. The whole thing is a only slightly modernized Elf II.

This article (on Page 61) could actually still be relevant to my modernized Elf. I wanted to do away with the hex keyboard, LED displays and mode switches (or buttons). This Microprocessor Product Development System also has a simple power-on reset (plus reset button), but has all the keyboard, display and mode selection stuff on a separate optional board.

I like that. Why not be modern as the default and retain the option to plug in this hex keyboard/display/mode buttons board and do things the traditional Elf way? I'm sure I can still eliminate some of the ICs. Does anyone know a good (and still available!) hexadecimal driver for 7 segment LED displays?
I have lived with several Zen masters - all of them were cats.

His last invention was an evil Lasagna. It didn't kill anyone, and it actually tasted pretty good.
