I would buy one but I have no electronic skills

Do we source components from donors? As in the special chips?

Yeah, you're going to need a donor board of some sort.

Yeah, pretty sure you're going to need a donor board of some sort.
No worries, got several. And some NOS chips.

Likewise. I have one board in particular in mind, which will donate it's body for science :)

Do you have a BOM readily available perhaps?

I have a BOM, not checked all parts yet, but will upload it at a later date.

Will need a donor ST for man parts such as , MMU, GLUE, Shifter etc, other parts like MFP, 1772, I do stock in my store, but a whole spare donor ST will have all parts.

The circuit isn't identical, example needs a Falcon RAM card (1MB or 4MB), PLCC 68000..

Other parts are generic resistors and capacitors etc which should be easy to obtain from any half decent supplier.

Hmm, so I guess I'm seeing SMD type PLCC sockets on the board?

If so then I'm going to have to get some sort of hot air soldering practise in, since I don't have an oven!!

:dizzy:

???

Normal PLCC sockets (not funky ones either, just normal PLCC sockets).
