Will the Exxos PSU work as a replacement PSU for a TT030?

Post by thesofa »

Not that I need one as yet but it's always good to know.
TT030 with Storm with 256 Mb Ram, Thunder with a CF drive and Lightning, HxC floppy emulator and one of Codekiller's magical Mono/Colour switchers, also 3 STS one has TOS1.0 AND 2.06 switchable with an HD drive, the other two are untested as yet, just bought for spares!!

I'm going to go out on a limb and say no.

I think the TT uses a PSU similar to the MSTE, and it is quite different to the standard ST that @exxos PSU replaces, and is more PC like.
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...

No it won't. TT/MSTE PSU has negative voltage rails, higher currents, totally different physical size. If it was compatible then there would be guides etc

OK, thank you
Pity.

Yeah, the TT power supply is essentially a PC-AT power supply in a smaller form factor.
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.
