I’ve been putting more video’s up on my youtube channel. The latest is a demo of my Macintosh 128K. If you are interested in the history of Macintosh computers, take a look. I also added a web page with a pretty detailed description of the hardware that I have used …

I have spent a considerable amount of time over the last couple of months restoring a very flakey Apple II plus motherboard to something approaching reliable operation. I expect that over the next few weeks, some final testing and debugging will resolve any possible remaining issues and I will be …

I’m restoring a very early Apple II plus in order to sell. I believe that this particular unit is a very unusual example of an Apple II plus, as it has the second style keyboard with “domed” power light. Apple II Keyboard Domed Power Light The bulb in …

I had to create this to debug a Apple IIc alternate memory bank issue. The source has been added to my 6502 memtest page. In the next day or so, I’ll be adding a youtube video to my channel showing the repair (but not the diagnosis). …

Back in 2015, I partially described how I used an early Apple serial card in an Apple ][ to provide a “glass” TTY emulation in order to check out some of my SCELBI software and interfaces. Since I don’t have a real TTY, I always had to set up the …
