With PVM with released an intro for the Tandy 1000 HX.
The Tandy 1000 HX uses the Intel 8088-2 CPU. Which is a suuuuper slow CPU (slower than the 8086). With all its wait states and its limitations on the video card (no hardware sprites, no charset redefinition) it makes it comparable with a Commodore 64. In fact, for certain things a Commodore 64 if way faster.
As the name describes it, it was a Commodore Expo in Las Vegas. But the format is a mix between conference and expo. It is a real expo, but with the social part of a conference. It is friendly and casual.
People give talks in a very informal way. I gave a talk + live demo about the UniJoystiCle. Everything went well except that in the middle of the demo my phone’s glass broke. But that wasn’t an issue since the accelerometer kept working.
You turn on your beloved SX-64 and you don’t see the blinking cursor. Don’t panic. Most probably one of the CIA chips (MOS 6526) is not working correctly.
The Commodore 64 has two CIA chips. What you need to do is to replace the one that controls the keyboard, the CIA 1. But if you don’t know which one is CIA 1 and which is CIA 2, then you can either replace both, or do trial-and-error, or look at the IO schematics (hint: it is the one with the UB3 legend).
As far as I know any MOS 6526 should work:
MOS 6526 (found in the very first C64s)
MOS 6526 R4 (found in newer C64s)
MOS 6526A (the 2Mhz version, and I read somewhere that it works Ok)
So, in order to get the replacement chip, you can get it on eBay, or extract it from another another C64 or SX-64. The MOS 6526 chips on a regular C64, are located at the top-left corner.
I suggest using a chip extractor to extract the chips, although a flat screwdriver can work as well.
