The X68000 is a powerful, but proprietary and very delicate series of machines that do not tolerate neglect.
With a new power supply and the entire insect population of Honshu removed from its case, the swamp-bogged X68000 PRO can finally start up, but can it boot floppy disks? In this exciting conclusion to the series, we’ll jump through a frankly ridiculous number of hoops – many of them ultimately proving to be unnecessary – in order to make some disks and find out.
Now that I had a reasonably clean X68000 PRO to work from, I set about restoring power. Rather than doing things the cheap way and strapping up my Meanwell four-voltage test supply, I decided to go whole hog and lay out a brand-new power supply PCB.
What happens when you bid on a Sharp X68000 PRO without looking too closely at the photos? For one thing, you win the auction. What also happens is that the computer spends a while in your garage, waiting for all of its little tenants to be vacuumed out.
You might recall that I own a Sharp X68000 ACE, the world-beating, sprite-spitting computer of everyone’s dreams. So far, though, the ownership experience hasn’t been the most fun I’ve ever had. Repairing the battery damage in mine has been challenging, as the damage goes deeper than I first thought, but I have accomplished one thing so far: installing a more reliable power supply.
Another postie-threatening crate arrived on my porch this week. There’s a lot of projects in this one; I’m not even sure a single one is “usable” as-is. This one sort of got away from me, but those are the fun kind!
