Wonderfull achievement :) DCD support coming or the logic can't fit in the ATF ?

Yep that's a possibility as well

Thank you for this! Very useful I had to use the previous version of FixupBSR6 from this commit because the last one gives me some error FixupBSR6.py> Running... Traceback (most recent call last): File "ghidra_scripts/FixupBSR6.py", line 137, in <module> fixupBSR6(ip) ^^^^^^^^^...

Hello, While working with LW ROMs, I noticed there is an hidden image in the IIsc ROM. It's not really visible on a classic CLI hex editor but if you mess with sizes it starts to stand out. It's a RAW black and white MSB first. @Danamania helped to recreate the image faster than I could mess...

Read the whole thread, interesting. About Valkyrie performance, if you look at the Valkyrie DeclROM on a 5200/6200, there is 68k in there. So part of it is emulated. It may be just for basic stuff like resolutions listing or initial bringup, or it could be some other advanced routines as well...

AFAIK there is no Linux for PPC upgraded blackbirds. Mainstream Linux PPC do expect some sort of OpenFirmware. They were patches to run on OF-less PowerMacs for Linux Kernel 2.4 back then, but it didn't include the PB540

Can confirm this is a good idea and they work great. Used them in a few of my 030 schenanigans. Overall, nice progress !

Only the W65C22N, the W65C22S is still produced in PLCC form (for now). I've tested one in a 512ke bench board, it works fine except reading the 1Hz tick from the RTC. It isn't behaving as expected. Think it's juste one pull-up away but didn't had time to test it Don't have any SE/30 bench...

If the daughtercard is this one Then there is high chances that the ribbon cable is broken

Build by @Jockelill with the red aluminium case

Best resistor value

Looks like a fine list for me. Pretty sure I used 1/4W resistors with values close enough (like 6.8kΩ or 7.5kΩ should work fine). 12V rails are actually overkill in modern PSUs, it's the -12V that's sometimes missing. You can split the +12V in whatever arrangement you want, it should work fine.

First congratulation for your build. Interesting about the issue, this is the first time someone had an issue with controllers compatibility. Like @sfiera said, there is a few differences with PAL and NTSC controllers. Maybe some Nintendo specialist can chime in TashPad only pull Latch with a...

No idea where the issues lies, but you I can help you check the basic signals Check "clock" signal continuity like this (page 5) - CL1 should be in the kHz range, probably around 12 kHz ( short pulses, may be off by a factor or 2-4 depending on LCD model ) - CL2 should be around 1.9 MHz ( about...

Very insignful thank you! Looked a lot of them and didn't find anything really major. Guess the biggest difference is between Found a dead 820-0615-A over here and it has the ASCO sound chip whereas yours are the CS4216 one. Reading through both data sheets, it seems that there they do have...
