![Restoring a Commodore 1702 monitor using a main board from 2023
Its no secret that I simply love the JVC built Commodore 1702 monitor. Its a solidly built and excellent performing monitor.
One thing that lets the monitor down is the fact that isnt a multi-standard monitor, meaning it only support PAL _or_ NTSC (depending on where there monitor is from.)
Another common problem with these monitors is that most 1702 monitors are now nearly 40 years old, and can be quite worn out.
Lets fix both of these issues by making a one of a kind multi-format and improved 1702 monitor!

![The VIC-II Kawari is a game changer for the NTSC Commodore 64
Sometimes things come along which are neat, but turn out to be so much better once you look deeper. For me, this is one of those products. The Kawari has some awesome features which truly make it a game changer.
Updates:
1) The PCB design files have not been uploaded yet to github. The firmware and other supporting software is open source but the PCBs are not open hardware (yet).
2) There are some limits re: using on-board oscillators. Some specialty cartridges that use the dot clock pin on the cartridge port wont work unless you move the clock src jumper to motherboard position. The Kawari site has more information about this.

I finally was given an awesome little 9 Sony Trinitron TV that was actually in one piece. The one thing I always wanted on a small TV like this is a RGB input, so lets add one!
WARNING: Do not work inside a CRT unless you know how to be safe. There are dangerous voltages inside a CRT, especially when plugged in.

![Leading Edge Model D Repair
This Leading Edge Model D has an issue on the video output which is built onto the motherboard. Lets use some logical reasoning and deduction to figure out exactly which chip is bad to get this machine up and running again.

![Is an IBM PC usable at the same clock speed as an Apple II?
Ah yes Ive always been curious how a PC would perform if I ran it at the same clock speed as most 6502 machines including the Apple II: 1mhz. Lets first see if I can even get a PC to run that slow, and if I can, how does it perform? Is it usable? And as a bonus, I find out what the slowest possible clock speed I can take this PC to.
0:00 Intro and why I want to do this
17:23 Getting a PC to run at 1Mhz
37:01 Lets run some games!
1:03:03 What is the minimum clock speed this can run at!?
