Hello
What form is called a socket 7 board with 1pc raiser ?
- What is the case style is it a custom case for Fujitsu ( OPTi Viper.) ?
+ ATX is >"1999+" PC cases ( Large rectangle opening: Pentium II,socket A,...).
+ AT is <"1998" PC cases ( Has a hole for old keyboard connector: Pentium 1,486,386,...).
LPX is the board itself, there is no standard for the riser boards.
I have seen the following riser boards in LPX boards:
- plain ISA
- ISA+VLB (only one VLB slot on riser)
- EISA slot used for ISA and PCI
- Proprietary with ISA and PCI
LPX was used for 286 allready.
Cases used for LPX boards are non standard, but sometimes interchangeable.
Many OEMs had LPX in their portfolio (SNI, ASUS, IBM, DEC just to name a few)

Oh well, I have good memories about the LPX form factor...
My childhood system was a "Tulip Impression Line Compact" 486 machine, which had an LPX board as well.

Still trying to obtain this machine again, but Tulip systems in general show up very very rarely, and I have never seen this particular model for sale anywhere.

Yep, and it gets worse - even where risers and boards match, there's no guarantee the case will. I had an IBM PS/1 486 motherboard with matching riser that was about 5mm too far forwards for my generic (yes, they exist) LPX case.
