Joe's Computer Museum

An 80's kid playing with old computers, and sharing that love with the world. Selling cool retro/vintage computer gear!
To everyone waiting for their notification of LisaFPGA stock: I am actively watching my front door camera so I can hop on that as soon as humanly possible. Blame FedEX for delaying the delivery by a day!
My ticketing system got spammed by an AI robot wanting me to sign up for their useless garbage, because the vendor used it in a Teams meeting I was in with them to summarize the meeting. Just... take notes people. Write while you're talking. It takes infinitely less energy.
Would the world appreciate if I created an Apple /// Profile Interface card? Original cards go for crazy money and ... there's like no reason for it? It's 100% jellybean logic chips.
What eMMC to USB controller chip? I don't know what you're talking about. (hacking a Ubiquity UniFi Dream Machine Pro to try to revive it)
Go home Ubiquiti Unifi Dream Machine Pro, you're drunk. Poor thing has a bad eMMC. No amount of e2fsck and rebooting makes it work. I could try to replace the surface mount eMMC...
JCM-1 has a (mostly) working video output console. Now we can do some optimization. Hurrah! I still have to handle backspaces and literal character positioning. The VDP doesn't make it easy. But then again, most computers from its era had to do it the hard way.
Milestone established: JCM-1's character out routine sends chars to the VDP instead of serial. Next step: rewriting the output routine for the VDP's memory map instead of an ANSI terminal.
What a week to launch a bunch of new products, have a weekend BlueSCSI blowout for VCF Southwest, and restock PicoGUS. You can head to JCM-1.com and make that number bigger, if you want. :D
3) No reset button, eh? Then how did I fix their back office data stream by pressing the reset button, I wonder.
2) This was the inside of the right panel. We're just gonna.... close this and not think about it too hard.
Late night tech work: a thread. 1) This is the amount of space I had to work in. I had to open that left panel on the Veeder Root *toward* me, get around it and see inside the box. That stuff to my left? That's the soda syrup rack that's bolted to the floor.
The JCM-1 Single Board Computer can now control a TMS9918. Datasheet & internet suggest different things; the program examples & data lines didn't match. 1:1'd the data lines (i.e. D0 to CD0, etc) and bingo. Anywho: it's working now. I can start writing libraries.
JCM-1 has graphics. They're the wrong graphics. But at least I know that I can send commands to the 9918 and -it- does something; so at least the address decoding is correct. Progress?
