That's not a real PET - REAL PET computers come with the square chiclet keyboards :mrgreen:

(cough - some of us started their 6502 computing pre-PET with the Kim-1 or AIM65 boards blush)

This is a wonderfully pointless project that I've watched more than once and wondered why, then gone wow wishi could have done that!

And I'm an oldie too! I started with an 8080 home built bare bones board with 7 seg displays and toggle switches then moved onto a home built uk101 (6502 1k RAM) ..

Don't have one of these old computers, even if I do remember 80x25 green screen.
My first screen was an old B&W TV converted to a white 80x25 :lol:

Hmm, use a Zero so a Pico can display YT vids on a tiny LCD?
Wonder if the PicoW could do it alone, using an analog Pal/NTSC LCD?

Blimey, it was the young'n's who came along with their new fangled, memory mapped, green screens. We had paper tape and teletypes.

The original PET (with the calculator keys) had only a 40 x 25 screen, as were the first CMB machines, (with a real keyboard) like the CBM4032
only later when the hardwired video generator was replaced with a programmable video (sync) generator, the MC6847 there were 80-column machines like the CBM8032.

But IMHO a PET should have a 40 column screen, to be compatible with most software.

and yes, I too started (As far as only a working computer counts) with a KIM-1.

That brings back memories. :D They say that your memory is the first thing to go. I forget what the second thing is?
A green monochrome screen is one of my oldest computing memories. Along with a blinking cursor, lol.

ADM 3A terminals for the win (lower case text was an *option*). But then, I go back to before there were microprocessors.

At the time I hated the change over to lower case but now looking at old capitalised programs is like having snow blindness.

As mentioned ..... the cursors, block flashing, underscore flashing, underscore constant, block invert and the worst was block invert constant with character flashing on a orange display, even normal characters looked like you were playing space invaders.

Yep, I remember using them too, & the orange ones, before 'paper white' came along. 8-)

You could actually record the 110 baud screech from the acoustic coupler on a cheap cassette tape recorder then play it back as input, and it would work!!!
It took 60 years of very difficult engineering to go from the invention of transistors to the smartphone with no new physics involved in the process.

Bah, kids today. When I started we programmed in ones and zeros - and sometimes we ran out of ones!

We had that issue too. ISTR we had a "bit basher" machine that would take old, worn out bits and hammer them straight, ready for re-use. Solved the issue completely.
