I could just be a simple Blinky light circuit, just to make comment to the inderlying.technology that supports our hobby. How about that old 6502 test circuit?. Very easy to make into a shirt design dors anyone here knownwhat Inmean? I could draw it if anyone not sure On Sat, Jan 28, 2023, 6:48 AM Jeff S via vcf-midatlantic < vcf-midatlantic@lists.vcfed.org> wrote:
The 74S181 is a remarkable chip in computing history, but I feel it may be too esoteric on a t-shirt if we were make it the theme of the t-shirt.
If the schematic was used as a generic graphic, along with a VCF slogan or something, people might easily understand it as "something about computing." If we called it what it is on the shirt, it'll probably generate questions like, "why this?", As opposed to the more common, "What is this?"
Questions from the public are good, but questions from a confused public are not as good. Unless we have exhibits or a show theme about the historical significance of the 74S181, then it's schematic graphic wouldn't work as a t-shirt graphic focused on the chip itself. It might actually hurt t-shirt sales. If you showed one of our average visitors a labeled picture of the 74S181 and an IBM PC, and asked them which one they would buy as a t-shirt, what do you believe they will choose?
Think of it like this... why did we put a Commodore 64 graphic on a t-shirt before, instead of a schematic or block diagram of its VIC-II chip? The latter is a significant chip in computing history, but people will more readily recognize a computer more than a specific chip.
I first wasn't wholly set on suggesting an IBM PC as the t-shirt graphic, but good points and arguments were made in this thread about doing so. Either way, the t-shirt graphic should be something more readily recognized by a passing viewer AND be historically significant this year. In lieu of any other ideas, the IBM PC would be a better choice in my opinion.
The 74S181 sure would be a great exhibit of historical significance if someone needed an exhibit idea. 🙂

One working circuit idea: I just was researching the TI ALU that some mini computers used prior to microprocesses, 74S181. It was pretty influential. The logic diagram could work as a graphic to wear.
