@rubber_jonnie
Definitely worth checking.
Just hope mine is OK as I really don't have too much time for all my other projects still in stand-by.

Re: Sharp X68000 XVI inbound (tomorrow...)
Everybody was out today morning, so I managed to fit the Xellent30 booster in my X68000 XVI.
The motherboard was quite a PITA to remove. You have to be very careful not to break something.
Just in case, the bottom of the Xellent30 is insulated.
I have also removed the pull-up resistor since MMU only causes issue with NetBSD and the X window system.
Looks quite empty here...
The Xellent30 fitted on the motherboard.
The motherboard is back in the case now. As you can see, the RF shield has to be completely removed.
And since there was no smoke, I consider the mission complete.
Now time to install all the necessary software for the Xellent30.
Stay tuned !

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.

Re: Sharp X68000 XVI inbound (tomorrow...)
And here we go:
First, a test to check the Xellent30. Everything is OK !
The boot screen I get after a Reset.
And the perfs at 33MHz.
Now time to turn the Data Cache on...

Fantastic! Great machine and one I'd love to get, but not so easy or cheap in the UK.HigashiJun wrote: Tue Jan 07, 2025 10:11 am Indeed it has !
