I got a TRS-80 CoCo II off a friend about a month ago. The RF output was atrocious so I got a composite mod off ebay. Really happy my sketchy solder skills were good enough to get it working. Now I've just got to figure out what to do with this thing.

Beautiful. (This is a Family Computer Network System HVC-050, btw)

The inside of a Famicom Network System unit (HVC-050) and the RF shield of the modem portion is covered in rust.

This thing is ridiculous. No, i can't put the controllers back on the sides.

Got a Souseiki Fammy in the mail yesterday. Gonna be figuring out FDS dumping in the coming weeks to get these disks backed up. I also plan on getting the rest of this device reverse engineered and documented.

Milestone reached: #Homebrew on the StudyBox! Getting this working was a bunch of really hacky code, so I've got a lot of cleanup ahead of me.

I've started to extract some screens from side B of that Darwin tape. It's a music program of some sort. And there's a horse race thing too? Idk. Anyway, I'm doing more reverse engineering of this stuff tonight if you want to stop by: www.twitch.tv/zorchenhimer

I'm not convinced the colors are correct, but they're probably close.

I was able to extract some screens from that Darwin tape over the weekend. I've also confirmed that i need the Model 1000 firmware to play the tape. It will not run with the SBX-01 firmware.

I got my hands on a rare tape for the StudyBox Model 1000! This tape will not work in the newer model SBX-01 for a few reasons. If I can get a dump of the firmware for the Model 1000, we'll be able to play these tapes.

I think my license expires soon. Just a hunch.

Program output with "Licence will expire in 3 days" repeated 32 times.

I've been making a lot of progress on my NES Tetris project. This is versus mode. I'll be implementing sending garbage rows soon(tm).

After having one of these for a while, I finally got around to taking decent pictures of the boards last month. I've been told this is a revision 1 boardset. Full resolution images can be grabbed from here: zorchenhimer.com/pics/titler/

The screen shake makes the hard drops feel so much more aggressive.

I got ghost pieces working last night! There's still a long way to go, but it's mostly playable. This works on real NES hardware, btw (colors and all).

Zorchenhimer @zorchenhimer.com · 29/12/2024

Scores, hard drops, & the ghost piece on the agenda today. Let's see how much I get done. www.twitch.tv/zorchenhimer

It feels weird making real progress on a project. (yes, this runs on real #NES hardware. Don't let the colors fool you)

Would you believe I actually got data off this?
