Re: Looking for a HD mounting sled for a PS/2 9595

Hi Teo !

Thanks for the link, but I got the machine to mess with OS/2 Warp (have 4.0
loaded) so the windows drivers are not important.

:-)
Good point. But the drivers are *really* useful if one uses W9x.

Can I use both the 50 pin and a 68 pin connector on that card at the same
time? Where do I find a 68 pin cable that connects to that card (not a
standard 68 pin connector)?

The card has 3 connectors total - 1 external and 2 internal.

Without going to deep into the mess: normally you should use the external plus *one of* the internal ports only. The internal and external ports have separate drivers but can operate in combined or separate mode - the internal ports are physical one bus where the 50-pin serves the lower 7 SCSI IDs only. Using both at one time is a "Y-connection", which is not allowed.
You *could* however do it, but it is lesser recommended.
It could work with the HD(s) attached to the 68-pin Fast-Wide port and one "lower device" like a tape or CD-ROM to the 50-pin Fast-SCSI port, given you use "Fast-SCSI compliant" termination for it.
But I would not bet my life on it.

Next: there are no U-SCSI adapter cards for MCA available.
The best you can get is that Fast-Wide you already have and a Fast-SCSI adapter (Future Domain 1600 based - alias IBM "Patriot" adapter). No USCSI.
Of course you can run U(W)SCSI devices on them. Here on my machine I have an IBM DGHS 9.1GB UWSCSI drive on the FW-SCSI adapter. No problem.
I even ran SCA-80 UWSCSI drives with 80-to-68 converter on my machine. Takes a bit more room however.

About parts: I could see if I have a spare drive tray (most likely) and if I could manufacture an appropriate cable from my stuff. I used to have 7-drop Compaq UWSCSI cables with integrated active termination at the lower end. There I cut off the adapter plug ... then crimp a Molex 72660 (68-pin "IBM variant") to the cable and here we go. Length is usually sufficient for a Mod. 85 or 95.

Where are you located ?
