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?

What a blast from the past.
Several years ago when I got back into electronics I started getting test equipment and I found the Heath Tri Power Supply listed on page 77 on ebay for I believe $25. I kept it for a couple of years until a friend of mine saw what I was doing and got interested so bought a good surplus BK 1660A and gave my friend the Heath.

Why not use an old power suppley? As long as it works. The capacitors could dry out over time and then short out, but that's about the only harm that could come from the age of the power supply.

My friend is a couple of years older than me and he had a lot of free time so he drank. When he showed an interest in electronics I gave him the poser supply hoping it would help fill his time. He's been sober since I gave him the power supply but now he's addicted to electronics. 
So it was worth the investment!

Anything to get him away from drinking!
I took a look at the Heath ad any your power supply. They also had a dual trace 10 MHz oscilloscope for only 650 bucks! What a deal! Count in inflation and that would be at least 2000 $ today!

And I got a Rigol digital for about 1/2 the price it was then.

Far out of my reach at that time. 5$ allowance every week and parents that could not believe that I started to pry ICs from every old circuit boards I could get my hands on. They complained that I should not dig around in the trash.

Something must have gone wrong while scanning the magazine. Pages 73-88 appear come right after the cover.
They have a button to single step instructions. My Elf II did not have that one. Let's see how that works. My guess: They halt the processor at every instruction fetch cycle and continue when you press that button.

Youtube and the work ethic[^]
Many a true word spoken in jest ... and many companies that use this model. I'm sure that YouTube don't. Not really. Honest.

Hi All,
I need to ask does anyone know of a company that prints lanyard tags. I ask as my company has gone overboard on security & being the sort of anarchist I am, I want the blue lanyard with intruder or industrial spy rather than STAFF  I did try eBay and found NHS and MOD lanyards but nothing subversive...

Thinking about it, if you have 50 made for around £40, you could sell the others for £1.50 each plus postage on FleaBay ...
