SAD1024 analog bucket brigade echo chip.. wow .. the memories ..

Man, I'm showing my age here, but I remember going to the Radio Shack and learning how to program in basic on a TRS-80 Model IV... Used to go up there during summers and play some of those cool games on a Color Computer!!

I've always been grateful to the sales guys at the local RS for allowing a geeky 12 year old to sit in front of the TRS-80 color computer for hours learning how to program BASIC. 4K of RAM? Write efficient code! Good times.

RS used to discontinue items just about the time I figured out how cool they were.

The short upside to that was that sometimes I would find a box full of RS stuff at a hamfest for like 25 cents an item.

Back then I got SO lucky many times, going from store to store and finding the reduced priced parts still hanging, yet remarked along the walls - OR! - a whole box of the discontinued parts, I'd be just looking thru what was there and have a big mess going on with the stuff all sorted into piles on the floor and a few times the manager would come along and he would help remove any question of whether to buy or not by offering the whole box for some incredible price like $10 or $20.. I cant remember

I have 14 of those SAD1024 ICs!

I probably have 14 of these left also, some I used and they have one half of the delay sections fried out, some still brand new. At one point I had 5 of them in series with each other for the extra delay response.... nulling out that clock frequency/noise was always such a pain in the a$$!.
Building guitar effects was such a cool way to learn electronics! yet, only a few of the projects ever found themselves housed / 'completed' - into an end 'product'.... I have often wondered if there some way of using this chip for creating abstracts/images that are as trippy looking as the sound this chip produces.

Someday, soon hopefully, I intend to get back into building stuff, last month I ebayed 3 of some burr-brown "AD532J*"??? quadrant multipliers.

I always felt that I was 'too cool' to EVER become interested in computers and thought I would never learn a thing about them.. I felt they were for the dweeby nerdy types LOL

I have a sister who is ten years older than me and she had a high school friend who worked at RS. I think it was some time in 1978, he brought over to our house the first TRS-80 computer. That was it for me. As soon as I saw it I was hooked.

The laser show that MWK bought from Knott's Berry Farm in (I believe) '96 was run from a Trash 80.
