You can get one here:

I am on the list for a second one...
I didn't realise he was allowing people to ask for a second board already...I'd better get saving... :D

I guess a third list will start soon, as the second one is already full.

What do you mean, he's already fulfilled two batches already, he's now on the 3rd batch.

Ps @HigashiJun make sure to run DML's FPUTEST program, as my TT's CPU wasn't stable at 48mhz.

Yes, I meant a fourth list...

I will run the test before closing the machine, thanks.

Hmm, ran some FPU tests and everything was OK with FPUCHECK.

However, FPUTEST still returns the same error:

I'll try cleaning the socket and see what happens.

:(

I would say that your FPU isn't happy at 48mhz... this is the same reason I set mine back to 32mhz. Sure - you could get away with running some programs at 48mhz, but I don't like the idea of my FPU running at speeds which makes parts of it's internal logic to break.

Same for me...

But I also don't like the idea of having my CPU running at 48MHz and my FPU at only 32MHz.

I will grab a 50MHz certified FPU from exxos store.

Yay, this has just arrived:

As always, all the stuff from exxos reaches me in less than 7 days. :D

Now have to fit it and test it at 48MHz.

Nice :)

I think my FPUs (One in my MSTE and one in my A1200 accelerator) are 25Mhz, so that's nice and speedy. I take it that the FPU in a TT is mapped in a totally different way to the MSTE.
Collector of many retro things!
800XL and 65XE both with Ultimate1MB,VBXL/XE & PokeyMax, SIDE3, SDrive Max, 2x 1010 cassette, 2x 1050 one with Happy mod, 3x 2600 Jr, 7800 and Lynx II
Approx 20 STs, including a 520 STM, 520 STFMs, 3x Mega ST, MSTE & 2x 32 Mhz boosted STEs
Plus the rest, totalling around 50 machines including a QL, 3x BBC Model B, Electron, Spectrums, ZX81 etc...

Indeed. The 68030 has a special interface to connect to the FPU directly which the 68000 doesn't have.
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.
