sorry to ask a silly question out of curiousity but I presume that it requires a master-set single drive on the ide side right? (like no dual drives setup or even a single slave-set one)
still thinking of being interested in buying one of targ's rework soon enough as anything but the atapi-only bridges on ebay are just too freaking much $ in my own opinion :-s
The ACARD 765E chip should work up to Ultra160 speeds, according to the manual. Some benchmarks I did with a PCI Ultra160 host controller and an Ultra320 HDD vs. Maxtor IDE on ACARD are 78 MB/s and 65 MB/s, respectively. While one can use IDE HDDs on the 7722 w/7726 BIOS and on 8-bit 50-pin buses, the benchmarks are VERY slow - 275 Kbytes/sec - and generally not usable.
Have you had any luck using the 7722 w1.73Q or 1.69H BIOS on an 8-bit, 50-pin bus? If so, how did you accomplish this so I can replicate your work?
Yep my adapters are for the 80pin SCA type drives, however the design could be fairly easily adapted to 69 pin drives if there was enough damand for a 68pin adapter with high byte terminationI have some really good 50 - 68 pin SCSI adapters with high-byte termination, and I can't find them, darn it. Might have to get @max1zzz to do another run of his -- although I think those were SCA to 50 pin. I think the ones I can't find were the last ones OWC had for sale.
I remember getting a good 50/68 pin SCA adapter from compgeeks a long time ago and they sold little terminators for the adapter so LVD drives could be terminated on the 50 pin bus. No idea what machine it is in.

There's a clue the scsi bios gives when detecting the device whilst connected to the narrow bus on the 2940UW.weedeewee: You mention that you were able to get the narrow bus working on your 2940UW. Did you try booting from the connected HDD? If yes, and it worked for you, what is your host controllers termination set at? I left mine on auto. I tried with and without SE jumper on the ACARD. Do you have the SE jumper installed?
52 degrees celsus doesn't sound too hot. I had planned to add a 27mm heatsink with 25mm fan, but perhaps only the heatsink is really required. When you measured 52 C, was it with an Ultra160 or Ultra320 controller? And what was the transfer speed being used while you measured the temperature?
Disable wide negotiation for that device.
WRT the 16 bit tsop firmware issue. Just make yourself a file where every byte is 0xFF, then use romwalk to combine the two files together. the same way a Hi/Lo bios dump would be.
They used to give out bumper stickers with orders and for a time I recall getting jelly beans in the box of stuff I got from them. New items that were pretty much closeout stuff but cheap. Think I got my NIB PPro overdrives there when I setup my Intel Pr440fx Win2k server back in the day.Are those the folks that changed their name to just geeks.com later. And then closed up about five or ten years ago? I got lots of great stuff from them back in the day. Sigh.
