Good news: Got my RCA VP3301 video terminal with #CDP1802 CPU and RCA VIS chipset this weekend!

Bad news: DIN plug I ordered from Digi-Key for power input was missing one of the pieces needed to assemble it.

Good news: Raised the issue on the Digi-Key web site, and notice of replacement part shipment being approved arrived very quickly, even though it's late Sunday evening!

Bad news: I have not powered up the terminal yet.

Good news: I did dump the terminal's ROM, which is not believed to be archived yet by the #COSMAC community! It was even my first time actually using my #glasgowinterfaceexplorer for a real purpose.

Bad news: While the terminal came with a user's manual and a schematic of the UART subsystem, it didn't include a full schematic, so it'll take some work to figure out the address map and whatnot.

Good news: Reverse engineering old computers is fun!

I bought an RCA VP-3301 terminal based on the #CDP1802 #COSMAC the other day on eBay. It just occurred to me that I have the same model of TV shown in this ad, except branded as the TRS-80 Color Video Receiver and marketed for the TRS-80 Color Computer. Are y’all thinking what I’m thinking?

"The COSMAC (Complementary Symmetry Monolithic Array Computer) is an 8-bit microprocessor family introduced by RCA. It is historically notable as the first CMOS microprocessor."

"Successors to the 1802 [ . . . ] have [ . . . ] enhanced features [ . . . ] There are also some minor pin function changes, but the line continues to be produced in its original 40-pin dual in-line package (DIP) format."

That's pretty cool! Just learned about the #COSMAC from @requiem 's comment hackers.town/@requiem/11209580… .
8-bit CMOS microprocessor

@vertigo for some reason I constantly mix-up SPI & i2c...

But regardless, my #rc2024 is going to be based on the #COSMAC (a much cooler name than "RCA 1802" or whatever) because I like it weird.
