After ages thinking about it, I decided to bite the bullet, I ordered everything but forgot the CPU socket
Is it ok to program the Xlinx at this stage? I guess so but wanted to be sure it was ok the apply power without the CPU.

Re: Starting to build my TF536
You don't need a cpu in the board to program it but the board will need to be powered independently from the programmer ie sat in the Amiga socket and the computer powered up.
If it ain't broke, test it to Destruction.

Or powered using the +5V & GND pin of the power header.
Intro retro computers since before they were retro...
ZX81->Spectrum->Memotech MTX->Sinclair QL->520STM->BBC Micro->TT030->PCs & Sun Workstations.
Added code to the MiNT kernel (still there the last time I checked) + put together MiNTOS.
Collection now with added Macs, Amigas, Suns and Acorns.

Well, something isn’t right, regulator is hot and so are the ram chips. Removed the chips and the reg is cool. The chips don’t read short or even low
Re: Starting to build my TF536
Are the RAMs the right way around?
A1200 rev 1B & 1230-IV 50MHz / CPC 6128 / CPC 464 / ZX Spectrum 48K / ZX81

Yeah the ram chips are on backwards... the small dot needs to match up with the white dot.

Re: Starting to build my TF536
I noticed that as soon as I replied. All good now.
I can’t believe I did that, I’ve been working with electronics since 94, and it’s my job
I feel like I massive dick now
