When I received my TT030 last month, I discovered it does not have a clock battery installed. The velcro strip to mount it to is still stuck to the inside of the case. I want install a battery, but I am not certain which jumper the battery wire will plug into.
Could someone point me in the right direction? Is it J400?
Thank you.

Re: Which Jumper To Connect Clock Battery.
Yes, it's J400. I've forgotten whether the key is on the ground or positive side though. I think it's the same as old PC motherboards.
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.
