The Many Incarnations of RADical

Part number	Description
030-0950-001	The original (5 volt PCI only)
030-0950-002	We added the special ksync connector for O200 (still 5 volt only)
030-1441-001	First "universal" version (3.3 or 5 volt PCI) for sgi 320/540
030-1649-001	Slightly better card outline for SN1 (O3000). Also "universal".

To rework 030-0950-002 assemblies in order to be used on 3.3 volt PCI (sgi 320/540 or SN1):

Instructions:

You are going to cut five traces on the board. Read all the instructions before you start to cut.
- Cut traces going to P2 pins A10,A16,A59,B19 and B59.
- As you count, BE SURE to count the virtual pins in the two key slots! 12, 13, 50 &51 are virtual pins lost in the slots.
- P2 is the regular PCI edge connector (ignore the 6 pins of P1).
- The 'A' pins are on the bottom side of the board, 'B' pins are on the top (component) side.
- Remove at least 1mm of the trace to ensure the connection is broken.
- If you place the board with PCI connector down, bulk head to the left and component side up, then the pin numbers start at 1 on the left and increase in number from left to right.

Warning! If you are trying to use any of the first three Radicals in SN1, it is easy for the PCI carrier to mis-align the card as its inserted. That's why we made the 1649. If you suspect that the card is not being fully inserted into the PCI socket by the PCI carrier, try inserting it WITHOUT the carrier. Its tricky. Do this at your own risk.
