Not just a motherboard, but more of a "single-board-computer", which includes built on, many peripherals that a separate ISA card would usually be needed for.
Can be used as a full featured XT without any cards.
Can add Sound, Network Card, or more storage/connectivity via the four ISA slots.
I recommend reading the user manual in the links at the bottom, for more detailed information.

8088 CPU is slightly slower than NEC V20, but with greater XT compatibility with some software.
NEC V20 is a little faster at the same clock speed, and supports 80186 instructions.

The 512K VGA RAM upgrade is not useful for most tasks. It is only needed for 1024x768 16-colour, and 800x600 256-colour; quite high for a mere 8088, and not supported in almost every application you can use on this. Best for programmers or novelty seekers.
The 8087 is also not useful for most users. Only software that specifically supports it will see a speed increase, such as CAD or spreadsheet software.

Includes:

  • NuXT v2.0
  • I/O shield
  • User Manual


There are photos with and without the onboard PC/104 VGA option.

A CR2032 cell is not included for shipping reasons. You must purchase one separately if you wish to use the RTC.

A case or power supply is not included. They are in the photos for demonstration purposes.

Disclaimers:

There is a 1 year warranty for repair/replacement.
There is no guarentee of compatability with any of your hardware, monitors, etc.
If issues arise and can't be solved over emails, you will need to return it to me. I will usually pay for your return shipping, if quoted prior, but that is up to my discretion.
