On June 26, 1913, Maurice Wilkes was born. He led the team that built EDSAC, the first practical stored-program computer, and pioneered microprogramming, leaving a lasting legacy in computer science and engineering.

Was it supposed to go up on YouTube? I wanted to go to that panel last year but was told it was Microprogramming, meaning it was only for people on the highest level badge. I didn't have that so was turned away. I was definitely not happy about that.

When new programmers say Python or C is tough, please try assembly to get a touch of real microprogramming.

Would love to go to this, but it's part of the Microprogramming package meaning it's reserved ONLY for the highest level badge. I didn't buy that, of course. Learned that lesson last year when I wanted to see a panel with Alan Sepinwall! There was no getting in at my badge level.

We have in production a set of standard MOS/ LSI calculator circuits that perform the functions of add, subtract, multiply and divide.

But many of our customers want more.

Buy an EA S-lOO set for only $158.46

Electronic Arrays

We have in production a set of
standard MOS/ LSI calculator circuits that perform the
functions of add, subtract, multiply and divide. But
many of our customers want more. So we modify,
expand, and design new circuits that provide the
functions and organization our customers want.
The EA S-100 calculator circuit set was
designed with a high degree of modularity.
By adding new circuits, and special
microprogramming of the Read Only
Memory, many additional features are
possible.
You can add in square and
square root, additional
memory, grand total,
fixed and floating
decimal point,
trigono-
metric
functions,
character
generators for
graphic displays, and
also a printout capa-
bility. Electronic Arrays
will design the circuit
functions you want.
Buy an EA S-lOO set for only
$158.46 at your favorite EA
distributor. Evaluate it. Then let's talk
about your production needs or custom requirements.
