So far today, replaced CPU socket and found a broken bodge wire that was ocasionally making contact, hence confusing the hell out of me.
So now I can properly concentrate on finding why my floppy doesn't work
Edit 1
Ok, so now the STF boots to TOS, sees the floppy but won't read or format it. I get 4 bombs generally when trying to boot to a floppy.
When I boot up the diag rom it passes ram, etc. It will do track seeks and speed tests on the floppy but not format it. I get error E9 when I try to format.
So now a couple of steps forward, which is cool.

Re: Forgottenmyname - Progress
thanks, getting there slowly. may just replace a couple more sockets, ie DMA and Shifter to rule them out tooexxos wrote: ↑Fri Nov 30, 2018 3:53 pmHope you have some luck soon!Forgottenmyname wrote: ↑Fri Nov 30, 2018 3:40 pm So now I can properly concentrate on finding why my floppy doesn't work!

Re: Forgottenmyname - Progress
Well, that was an interesting and probably the end of my STF project, at least part one anyway.
Last night had a power cut whilst I was playing with the STF, scope, etc. Powered it back up and no display, burning smell, etc....
I don't think it's the PSU as that's outputting all the right voltages but now my STF is dead.... hopefully not permanently.
Guess the luck exxos wished me back fired, LOL.
Still, I shall look on as you guys work on your STF's and will wait patiently for Part two / mongrel board.
Now off to see why one of my Mega's doesn't work properly too after last night.

Re: Forgottenmyname - Progress
Forgottenmyname, sorry to hear of your machines passing..
Re: Forgottenmyname - Progress
Oh no, can you test the chips in another st ?

Re: Forgottenmyname - Progress
I hope you had a doner card filled out!
Re: Forgottenmyname - Progress
LOL, yes I did have a donor card filled out.
I'll pop the chips one by one in another ST and see what happens. Hopefully its something daft like a transistor on the RGB circuit, as there's no output but the shifter is generating 16mhz etc still.

Re: Forgottenmyname - Progress
That is bad luck. Are you trying to out do me on the PSU failures / issues? I think I racked up 3 last month. Biggest one being my PC PSU which just went dead overnight. Not a small unit either Corsair RM850.
Lets hope you can salvage something out of the board i.e. its an easy fix.

Re: Forgottenmyname - Progress
And the not so amusing thing is that my "best" Mega 4 now has the same issue that the STF had, it won't read from floppy without 4 bombs.
