IMPORTANT NOTES: Please read.
Note1: Orders usually ship within a week, but could take 2-3 weeks longer if demand is high, such as after a new batch of stock becomes available.
Note2: Do not choose "Postal service" as your shipping option, unless you are okay with your box only being insured for $150 and declared as such. Choose DHL Express for very fast delivery (once shipped). I am not responsible for customs issues, if you make mistakes in your provided address, or if the parcel is returned to me (where you will be offered to pay shipping again or be refunded minus shipping).
Note3: DHL Express claims they cannot deliver to PO Boxes.
Note4: For your own data security, please only reply to, or click links in emails from monotechpcs@gmail.com or freewebstore.com.
Note5: Board may have slight visual differences to the product photos due to new board revisions or unavailable parts being replaced.
Note6: I used to provide PS/2 mice as an optional extra, but the Microsoft Basic Optical Mouse has been discontinued. I have a few left, available here. I am looking for a suitable replacement to stock.

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 IBM XT-compatible without any extra 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.
Features:
- 8088 and NEC V20 CPU support
- 8087 math co-processor support
- 9.55MHz, switchable to 4.77MHz or 7.16MHz on the fly
- Dual 64K ROM, switchable with DIP switch, writeable
- 832K RAM
- 640K conventional
- up to 192K UMB RAM (160K max when using VGA)
- UMB-Configured DOS 6.22 uses only 10K conventional!
- PC/104 Expansion Platform
- (optional) PC/104 SVGA card, with VGA port in the rear I/O area
- Real-time clock (uses a CR2032 cell, not included for shipping reasons)
- High-density Floppy controller, with FM support
- Bootable XT-IDE Interface
- Onboard IDE port
- Onboard CompactFlash card slot at rear I/O
- 64MB CF Card Included - loaded with DOS and ready to go
- 16C550 Serial Port
- PS/2 Mouse Port
- PS/2 Keyboard Port (can be jumpered for XT keyboards)
- Bidirectional parallel port
- ATX Power Input. Generates own -5V rail for those uncommon ISA cards that need it.
- 4 x 8-bit ISA Slots
- Front-panel connector for modern case buttons and LEDs
- Decent onboard PC-Speaker, with option to connect a larger one instead
- Can disable onboard peripherals and adjust resources used
8088 CPU is slightly slower than NEC V20, but with slightly better compatibility with a small number of old softwares.
NEC V20 is roughly 20% 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
- Built-in 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. They can be found in most supermarkets. The RTC is not required for the NuXT to work.
A case or power supply is not included. You can purchase a regular ATX power supply and microATX or ATX case from PC parts stores.
Disclaimers:
There is a 1 year warranty for repair/replacement.
There is no guarentee of compatability with any of your hardware, peripherals, 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.
