I have a Tandy Sensation!, an unpopulated prototype Tandy 1000TL motherboard with 16-bit ISA slots, and some of IBM's first LCD displays that I've never seen anywhere else.

It's funny, I figured that out by downloading the source and reading utils.cpp. Weird how that was my first reaction rather than actually reading the documentation...

A new mTCP is available. Here are some of the highlights: Much improved DNS support, including a local HOSTS file and support for a local domain name. TCP/IP flow control improvements for slow/bad connections and bug fixes for improved compatibility. Improved compatibility with "WiFi" modems ( …

I am aware of ethflop. It is an interesting solution to a very very specific problem so it makes it very limited IMHO. For example you can't even use ethflop to install a multidisk program as there is no mechanism to signal a disk switch on the client or the server. However, if you just need to get …

This is an exciting project. I started wondering about the viability of a pi daughterboard on an ISA card for hardware emulation years ago! I'm really surprised the Pico has the horsepower to push good GUS emulation. Is the MPU-401 mode going to be intelligent mpu compatible, with irq? The updates …

I would probably fall afoul of gatekeepers. I have been doing most of my retro computing lately on an 8088 motherboard I assembled myself, with video card/floppy controller/hard drive controller/network card/sound card I also assembled myself. All running on a backplane I built as well.
