Hear about the Uniscope 300 mainframe terminal from 1964.

In the early days of computing, the computing power was kept in centralized large mainframes and users would connect to them via so called "dumb" terminals. These often provided their output through a printer and continuous feed of paper. However in 1964 UNIVAC introduced the Uniscope 300, which was one of the first terminals to provide a video monitor for display. With the introduction of this system came the introduction of several concepts that we take for granted today and they are described during the reading of this brochure.
As I mention in the episode, $15,000 USD in 1964 is worth considerably more today, according to an online inflation calculator it is now worth approximately $144,000 today. So even if that was for 48 terminals as it seems to mention in the hand written note, that might equate to about $3000 per terminal in 2023 dollars.

to build and understand the inner workings of an 8 bit computer and
maybe one day pass it on to a grand kid
this episode -nop test
do a nop test, that is get the z80 up and running executing the nop
instruction
using the facilities of an arduino mega board running flash forth to
do that, talk about pictures
why? flash forth is interactive, without being such a big
application itself. Happily runs on an atmega328
why the mega, oodles and oodles of io, so emulating hardware should
be a snap
use the microcontroller board to provide 5 volts, clock signal and
data to get the z80 up and running
use the logic probe to see if there is activity on the address
bus

not the output on pin h6 (digital 9)
changed freq= some value to simply pulse, not interested in the
specific frequency
split clock and logic probe init words
added some words to control the reset line reset and run
added a word step that allows for single clock pulses
the test, mega board plugged into laptop, seral terminal running
spool up the logic probe
spool up the microcontroller board setting up a port to provide data

We have left the Tucson area and moved up into the mountains to
Clifton, Arizona, a mining town. Arizona is a major source of Copper for
the U.S., and Clifton has one of the larger open pit mines in the world,
and the largest in the U.S.
Notes: Forgot to mention that I hot glued the top lid (original lid
for the 'speaker box'), on top of the boards. I had used the device with
the top uncovered for a month because I hoped I would find a better
choice but after getting tired of the wires detaching and worrying about
the sdcard slot getting wrecked I decided to commit to glueing the lid
on.
The boards are very robust, I dropped them in the snow a few times.
They would stop working but after drying off would function.
I didn't find the datasheet with the resistance values for other
values until after I glued the lid so will have to open it up again or
get into one of the switch lines and do resistor combinations... now
that I know more I think I should be able to control the mp3 player with
one analog output pin from the arduino for all the functions, since it
seems the pin 8 that all the switch resistors lead to detects voltage
levels from the voltage divider created when one of the switches goes to
ground.
The robot is using 4 lines right now for mp3 control. Would be cool
if I could free up 3 more but I don't remember if any of them are
occupying an analogue slot.
No power button! None needed. Pause and unpause via momentary switch.
The charger board can charge from micro usb or usb-c and will protect
your 18650 cell from running flat and damaging itself.
