Thanks for the explanation, very insightful as always. I do agree with it, maybe not with the pure 68000s, a lot of embedded stuff relies on well placed nops. FX68k is just awesome work in that regard. Does TG68k has MMU support now ? (Sorry, just following FPGA stuff from a distance). Last...

Watched this with great interest, thanks for posting it Had a good laugh at the following issues: - The pesky JLC LEDs being to bright even at sub 1mA - RX/TX lines crossed - The TXS/TXB level shifter series oscillating on a parallel bus for no reason. My first projects also had theses...

Very cool! Looks like we were many working on this display thing. You guys tackling grayscale and color have some skill. Have you looked at the GSC registers and init from the super mario source code if there is any hints ? I can search them again if you want

Nice progress! @Melkhior it is not cycle accurate as well IIRC. But that's the best we got for now :)

Very nice pictures, also good gob on that ECSC soldering…

What are you guys CPU board revisions ? AFAIK we still don't know the differences, might be one of them

Missed this thread here. Awesome work! Same as other members here, given how how much work went into it and today cost of components manufacturing costs, that's about a $400 project from my estimation (you will always get dead boards etc). So $350 is still good value. You are just learning...

Late here but I've got a prototype ESP that converts the video from Omaha running in black and white to MIPI-DSI (so PowerBook 140-145 to a modern screen) Can confirm the timing findings above. It's basically 2 640x200 screens Unfortunately the ESP revision I'm using is broken (many DMA issues...

Got it, make sense. Tried to do something similar with Sonnet 4.6 (CC harness as well), it was stuck sometimes on some function calls. (My use case was trying to make it rename a ghidra disassembly output, I managed to have it off by giving it three different disassembly sources), otherwise the...

What model did you use ?

Has anything used it ? I've got the impression it was always some sort of tech demo. By the way the feature has been merged into Snow, it will be available in the next version :)

How wide are the 1400cs ROMs ? We were assuming 8bit wide ROMs

Hmmmm... The VIA cannot generate an interrupt on click and you checked the connectivity and the VIA so it isn't a VIA issue. Random idea: the mouse click is probably polled @ VSYNC. Do you have a pulse on pin 40 (CA1) ? Does the IRQ line kinda follow on pin 21 ? If yes follow the IRQ to TSG...

My man hoarding again! Welcome back :p
