Ed,

Looks like what I really want is an Adaptec 29160 which apparently superceeds the 2940U2W. The 29160 evidently allows for narrow and wide adapters at the same time without having to degrade the wide speeds downward.

I found the 2940U2W card locally for US$197.00 + tax which isn't bad so now the dilema is newer/older technology and higher/lower costs..

That and the cost of the adapter - 68<--->80 pin from the folks at www.scsipro.com.

Some things never really do change... <g>

I guess I need to see if the 29U2W can do this. If not I'll have to open my safe. <g>

Best,

DD


>>Hey Doug. The SCSI card I have is a Adaptec 2930UW. I don't know if the two are interchangable or not, but your welcome to it if you want.

Different chipset, and no support for bus clock speeds above 40MHz - it won't work with an LVD drive, and a U2 single-ended drive would be forced to operate at the slower Ultra data rate. It can be used with U2 single-ended devices, but they'll fall back to the commonly-supported compatible data rate; if you hook a U2 single-ended drive to an 8 bit SCSI-2 conroller, it will work, but only at the best rate both the HA and the device can negotiate.
