Nice LPX mobo due to integrated best possible VGA for DOS: Tseng W32.
1MB but is upgradeable to 2MB (have FPM SOJ upgrade in another auction).
Riser included and tested one isa slot with boot process to DOS.
As always in my items: various upgrades are possible if you need.
I can swap CPU to other, change ram/cache etc.
Many parts available for extra.
