It's about the same device, but I found an another approach to take at the plug and not mangle anything. Not gonna share it until it shows up. I don't want it to be a whole mess of soldering and drilling or anything, more of a almost drop-in procedure!
Finally was able to export my code today! Hopefully it works. Unfortunantly I followed a schematic blindly and need to figure out how to supply 3v to the rp2350... The part I got isn't outputting anything! Hopefully I can just replace it with another of his 10 buddy's and see if it works then.
Wow! 102% better! That's an improvement!
Wondering about how Sideburn put (I think 13mb) of ram in his Portable, and was wondering, how big is the ram space in the Portable really and can you use more of the empty space in the block diagram to max out the Portable. It was just a thought to...
So if it gets slower because of no /Dtack signal, couldn't you program a chip and put it on your PCB so that it asserts /Dtack?
EDIT:
I will try to get some speed tests from my PDS 4mb card... My Portable's torn apart right now!
Alright, wasn't able to get the plug yet (still looking). But came up with a FPC that you solder to the bottom of the motherboard. Hopefully it fits and works. It will be 2 weeks from now but 🤞.
