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

Yeah, you're going to need a donor board of some sort.
Collector of old Atari things:
800XL + Ape Warp mod, 2x 1010 cassette, 1050 + Happy mod, 65XE (128k) & XC12, SIO2SD, 2600jr, 7800 and Lynx II
Atari 520ST (1Meg) + Gotek, 1040STFM + Vortex ATOnce + Gotek, 1040STF long button floppy, 4160 STE with Gotek and ROM switcher, 4160STE with 32Mhz booster, ROM switcher and CosmosEx, not to mention various bare ST boards for testing including a PAK 68/2 :)
Plus the rest..
Amiga stuff, Mac stuff, Sinclair stuff etc...

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 :)

Snip
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.
4MB STFM 1.44 FD- VELOCE+ 020 STE - 4MB STE 32MHz - STFM 16MHz - STM - MEGA ST - Falcon 030 CT60 - Atari 2600 - Atari 7800 - Gigafile - SD Floppy Emulator - PeST - HxC - CosmosEx - Ultrasatan - various clutter

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!!

???

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