Compaq Deskpro 8086 (1984)

Now here is an interesting unit recently discovered... an original Compaq Deskpro 8086 from 1984; this one was manufactured in 1985!
This was *the* very first system, along with the original Compaq Portable, to be 100% IBM-compatible.

Of course other systems had x86 processors such as the 8088 and 8086 back in the 1980s, along with an 8-bit ISA bus, but many of them were only up to 95% code-compatible.
This meant that the code either had to be patched to run on the non-compatible system, or a specific vendor-version of the software needed to be released.

This was not the case with the Compaq Deskpro, though!
This unit is running with the following hardware specifications:

- AMD 8086-2 16-bit CPU @ 4.77MHz (the original CPU of which the x86 instruction set architecture was based on, from 1978 - second-sourced AMD model rated for 8MHz)
- Intel 8087 16-bit FPU @ 4.77MHz ~ 50 KFLOPS computational processing capability
- 640KB of DRAM (20-bit address bus - lower 640KB used for system memory - upper 384KB reserved for hardware)
- ISA Compaq CGA Video Processor w/ 16KB VRAM
- ISA 3COM 3C503 10BASE-T/10BASE-5 NIC from 1989 (the very first 3COM NIC to feature a built-in Ethernet transceiver)
- ISA XTIDE Compact Flash card w/ 2GB CF Card
- ISA FDD Controller w/ twin 1.2MB 5.25" FDDs
- ISA ST-412 HDD Controller w/ twin Seagate ST-225 20MB MFM HDDs
- ISA Serial/Parallel Clock I/O Card
- MAGNAVOX Computer Monitor 80 composite amber monochromatic monitor from 1989
- 65 watt AT-compatible PSU

UPDATE:
- AMD 8086-2 16-bit CPU was removed
- NEC V30 16-bit CPU @ 4.77MHz - 8086-compatible CPU with 8080 ISA compatibility and an 18% performance boost clock-for-clock compared to the the 8086
