Before the X68000, Sharp had a Z80-based 8-bit personal computer that tried valiantly to compete with the PC-88 and MSX. Actually, they had a couple, but the one that I’m most interested in is the Sharp X1. It combines flash VCR-esque styling, sturdy construction, decent graphics capabilities, and AY-3-8910 sound. What more could you want? Well, you could put the word “turbo” on the front.
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.
Now that I know that the computer wasn’t horribly killed by my recap job and repair of all those broken traces in the ADB input system, let’s take a brief moment to recap that original Astec power supply from the “bad” LC. And fix the video!
While I was working on the bad ADB Mac LC, I tested it by using the “good” power supply from my childhood Mac LC. How good was that “good” power supply, though? Well, it smelled a little fishy.
When we last encountered the Tandy 1000SX, it decided to bravely blow itself up rather than face us in battle. With a lot of elbow grease and a little bit of solder-slinging, this testament to 80s shopping-mall computing will live again.
I picked up a Tandy 1000SX recently. My plan is to use it for experimenting with Tandy graphics and sound, and maybe even port a few hobbyist games to the platform. As per usual with my pick-ups, this one needs a little bit of work before it can be usable.
