H5 Remake Board & SidecarTridge
Re: H5 Remake Board & SidecarTridge
What revision is your H5
Re: H5 Remake Board & SidecarTridge
My RTC pads are soldered together. My H5 is Rev. C5B. I’ve been over the whole board today and did find a badly soldered resistor on one of the bus pull‑ups (my fault — it was a bare board from Exxos). After fixing it, it made no difference.
I do have a mini handheld oscilloscope, but it’s a bit naff. It does, however, show activity on the UDS, LDS, ROM3 and ROM4 lines on the cartridge port when powered on and reset. It all looks virtually the same as when I plug the Sidecartridge into an original Atari ST.
So I think I’ve reached the limit of my capabilities!
