EDIT: What is probably confusing is I was reading it as the IRQ of the MFP not the IRQ from the CPU. Its actually the MFPINT line into the MFP.
Where is the resistor on the schematic ? I looked on ST and STFM and just see MPFINT going from MFP to GLUE, I don't see a resistor anywhere ?

I can't really post the image though, that would be illegal :shock: :) But if you were to search the internet for say "Flying Shark (1988)(Firebird)[h][One Disk].st", you'd probably find it somewhere ;-)
Nothing stopping posting things in PM..

Re: ALPHA MODIFICATIONS

GLUE DATALINE FIX A "good" mistake here.. While GLUE states D0 & D1 on the GLUE itself, the actual data lines are D8 & D9! So nothing will be setup right internally on the GLUE and pretty much everything it controls will be "wrong" because it will be getting bad data. The fixes are thankfully not t...

When doing another PSU recap, I figured that instead of desoldering the mains wires from the PCB, it's more practical to just unscrew the rear terminals :roll: :-D
ahh, I don't do either, I struggle with it in place :)

Re: kodak80 progress

It can only really be, bad soldering, solder shorted to a via somewhere, bad contact on sockets, or bad chips. Other than metering everything out which is very daunting vs each signal on the schematic, it's the only way to find out which line are "broken", there isn't much else if its not even tryin...

Re: Icky - Progress

One thing to look at, is scope out the 4MHz to MMU, and E-clock to ACIA... see if there is any bad ringing on the signals... Really need the keyboard or rs232 working so we can control diagrom.. it does have a video test which displays a image.. The video issue kinda looks like the bitplanes are get...

Re: Icky - Progress

IRQ has a pull up.. 1.JPG 2.JPG Whats probably confusing things is some of the single resistors I have moved to a resistor pack somewhere instead. It was done to reduce the amount of parts/soldering/space. I would suggest actually removing those resistors you added, possible the MFP can't work with ...
