Updated rom . By the way , I had to change the stock 68k for a 16mhz version .

I have an A500plus with a Spitfire500 in it and have done the config pass through ( wire to config out ) and it works fine with both the A570 and the A590 . Iwould give more info , but currently have the A2000 on the bench and will be helping with the testing of the SpitFire2000 .

Have you had a look at PCB explorer ? If you highlight that address line it will show you where and how it runs . You can follow the trace to check for shorts . https://www.amigapcb.org/ You can change the PCB color in settings to make the route clearer .

U47 buffer for the PCMCIA . Any cards on the trapdoor expansion ? And memory chips , of course .

Correction chips are 7404 ( hex inverter ) and 1488/1489 rs232 drivers .

Have youhad a look at the SDBox , with a single floppy and this it could test any amiga you would want it too . https://github.com/jbilander/sdbox

The haetsink compound is 'Magnesium oxide thermal paste' .

They are the _BCASU and _BCASL for the trapdoor . On pin 1 end of the chip they are just tied high and on the other end they go to the trapdoor connector . Just like the A500+ .

If you give a list of what colour for what pin then we can give details of how to re-wire it for the amiga .

It is an aftermarket brand , maybe you had one that was made for the ATARI etc.. I know a lot of joystick manufacturers popped up making them for all the different machines of the time ( the same stick , just wired differently for each machine ) . If the stick is re-wired to the ATARI pin out...

ATARI , C64 and AMIGA as well as the SPECTRUM interfaces all use the same pinout for the joystick , that includes the 2600 . Maybe you had an adapter , or cable that converted it to ATARI ?

Looks more like an MSX joystick .

That is definitely NOT an AMIGA / C64 / ATARI joystick , the pinout is wrong .

As happens with so many sid's , part of the analogue circuit has gone faulty .

It is not the cable , but the green drive on the CRT . If you have no experience with this kind of thing , then I would recommend getting it done by somebody who knows what they are doing ! Very dangerous voltages in a CRT !!
