Asking Silent* to say hello is.... ironic.

The Pi 400 with emulator will be much faster than a Q68, and half the price. While there's something satisfying about real hardware, for plain performance and ease of access, this Pi 400 is going to be a real boon. Just waiting for the all black model to be released in February. Pink is not my thing.

Indeed. I was only thinking about it from the POV of a few simple S*BASIC extensions.

Eeeexcellent......

I'll email you when I have hardware. Should I implement space for a ROM, or will a driver be loaded?

I have a pile of counterfeit AY-3-8910 chips I'd like to use up. They're actually brand new working YM2149 that were remarked, and are likely from the exact same batch as the ones Ben Versteeg at ByteDelight is using. If you tell me what register base address you selected I can throw out a bunch of ...

I've been through all the machines in the house and not found it yet. I have two machines in storage that it might be on. I'll dig them out.

It has nothing to do with NTSC. It simply improves the 15 MHz clock fed to the 8301. The US QL has a JSU ROM which sets the NTSC bit in the 8301's register. This converts TV mode to NTSC with a lower resolution and repositioning of windows. Replacing it with a plan JS or Minerva ROM restores normal ...

It's Samsung's mod to buffer the 15 MHz clock signal.

I did this in around 2004. It’s a couple of computers ago, but if the file still exists I’ll find it. It also included variations of positions of internal connectors.

QL-SD is definitely one of Peter Graf’s most outstanding innovations. I don’t know where I’d be without mine.
