In the several years since I had build my Micro-Kim, I could never successfully connect it to a USB port on a laptop. It didn't matter if I tried minicom under Linux or hyperterm under Windows. The Micro-Kim just wasn't recognized. But, there was nothing wrong with the RS-232 on the Micro-Kim, since...

It's a classic 6800 CPU trainer, with breadboarding block and all address and data lines, and signals brought out for easy access. The ROM code is available, as are the schematics, and it shouldn't be terribly difficult to recreate from scratch.

This is a wild, crazy suggestion. How about a hardware emulation of the Radio Shack Model 100 portable (circa 1982)? You could probably substitute a Z80 for the CPU and maybe Small C for the Microsoft BASIC. Maybe just a bare board with an RS232 interface, and no LCD display . . . and an optional ca...

Vince, I'd like to see you do a single-board 68000-based computer, something like the Motorola MC68000 ECB or the HT68K "Tiny Giant" SBC. I believe that the 68000 and support chips are still available and reasonably priced. The 68000 boards have no built-in display and are intended to atta...

I've got the serial port working with a Thinkpad 770X, but only under Windows (Win2K, Hyperterm, 1200 baud, 8N2). It won't work on that machine on the (Puppy) Linux partition, using minicom. Don't know why not. So, that gives me two options, so far. 1) The TP 760XD, DSL Linux, 300 baud. 2) The TP 77...

Well, here's what didn't work for me: A USB-to-serial port converter. Didn't work under either Linux or Windows. The converter itself is okay, since it works with other applications. IBM Thinkpad serial ports for the "newer" models. Anything newer than a 760. There seems to be a basic hard...
