[inbox] RE: SCSI mixed 50 and 68 pin question.

[Mark Musone]

You can get an adaptec 2940UW scsi card for around $5.00 on ebay.
It's well supported under linux and has both 50 and 68 pin connectors..

I even think (I could be wrong) that they are electrically separate,
meaning that they will both work in their optimum speeds (don't quote me
on it, it's been a while)

Theres actually some on ebay right now for $2.50 ending in about 30
min..

Hmmm... Well, another card sounds too expensive for me to pursue any 
further. Don't know where, but I somehow had the impression that 16 bit 
devices (my HD's) would care not a bit (ha ha!) about whether 8 bit 
devices were on the same cable or not. Probably because they will work 
on the same cable w/ proper adapters.
I don't want to slow down the drive transfer rates. The 40 mb/sec burst 
is just too sweet to sacrifice. The only card I have laying around is an

EISA (remember that??) that I believe was used to boot a small server 
ca. 1994. It HAS to have boot bios on it. May be worth a look-see. I 
have one ISA slot, but I'm not sure I want to use it on my otherwise all

PCI setup. Wow! Ancient hardware is such a learning experience!

Thanks for the help!
