If M28 pin 13 has 2.13V, then I think that is enough to turn on T20. Which is why the power supply is "off". So what I think this says is * When you turn on the power switch (mem switch also on) the power supply tries to start * something triggers the PCS signal or the /RESET signal to clock M28

The processor adapter board is low profile, having pins short enough to allow the PCB itself to rest on the socket, on the main board. Then there is enough room for the CPU socket for the NSC800. The main rom, being closer to the front, has less room. In that case, no socket for the option rom.

my 2 cents; Worth it to see if you have valid signals at both the main ROM and at each of the installed rams but most importantly the "top 8k". meaning the 8K RAM that is closest to the system socket. if there happens to be a cracked track on the PCB, that affects the memory subsystem, you will

I believe that it is just not possible to use PC hardware ... drive, controller... to read a TPDD disk. The disk is encoded with FM whereas a normal drive is MFM. Or maybe that is backwards. Not sure but possibly a Catweasel drive can be used. But that is specialized. Perhaps though a real
