Notes

This board uses a proprietary riser card for ISA, VLB and PCI expansion slots:
FRU 06H3095, 2x 16-bit ISA + 1x VLB
FRU 06H3096, 3x 16-bit ISA + 1x VLB
FRU 82G3555, unknown, supposedly has PCI
FRU 06H3097, 2x 8-bit ISA + 5x 16-bit ISA + 1x VLB
FRU 82G3563, unknown, supposedly has PCI
The form factor seems to have inspired the later LPX standard.
This board was used for the IBM Aptiva 6492 and the PS/ValuePoint 6484, 6482 ad 6427.
