Thanks, everybody 
My current vision is to build an adapter so I can use my black CDTV keyboard with the A4kT. Should be easy, but some things about the 4000T are hard to verify due to very limited internet resources about the topic. I agree on the special feel of the genuine Commodore keyboards!
Firstly I will need the CPU, I'll try to get the basic A3640. I just want to get the machine up and running, then wonder about which Amiga OS to use, and then how much CPU and RAM I'll be needing. I have a feeling this will take years! :laughing:
I have already been looking at some parts from Vesalia (and sent a query about the AV module).
The A4000t uses the same keyboard pinout as the A2000/3000(just follow these pinouts). You could either internally rewire the cdtv kbd to match or make an adapter. just be sure u get it right! Blowing a cia in the 4000t is bad because its surface mount and not socketed.
You have many choices on Accelerator cards..
the A3640 is ok,but lacks ram expansion-16Mb fastram limit.usually has leaking caps that are installed backward on many revisions-Yes! even rev 3.2!
Warpengine 040/40 excellent card, 128MB ram support,good scsi.
Cyberstorm MK2 is a good card,supports 128MB ram
Cyberstorm MK3 is better and has UWSCSI(68pin) to boot allowing 25MB/s + SCSI speeds with the right drives.supports 128MB ram
Cyberstorm PPC The best of the bunch! UWSCSI,128MB ram,Supports os3.9 as well as 4.x
GVP 4060dt Ok card but only supports the slow FastFileSystem.Scsi seems to work well, siupports 128MB
Apollo 4060-Usual apollo crap- Supports 128MB -scsi is mediocre at best and some have problems with these cards.
Quikpak 060 - the Only card to support EDO ram,up to 128MB.Some versions of these can be picky or may have problems.
for 040:
A3640 is not great,but will get you up and running cheap.
Warpengine 4040
for 060:
Go for the cyberstorm MKII(040 or 060),MK3(060),or PPC(060/50 and 604e/233)
