+dhe Posted May 4 Share Posted May 4 I've been using a ASCSI card in my Geneve for years (decades?). Last time I tried to power on the Geneve - it locked up and wouldn't boot. I noticed the drive chain had fallen off - easy to do, since my ASCSI card didn't have twist in locks. Not sure if that's a feature of all of them or not. @InsaneMultitasker suggested I pull the drives off and hook them to a PC and see if they all came up. I contacted Chicken Systems - vendor for the SD2SCSI and asked how they tested SCSI devices and if they knew of a good USB 2 SCSI Controller. The answer is, such a thing doesn't exist and they use an Adaptech AHA-2940. So I sourced one of those on EBAY. Then I dug out of my pile of old computers a mid-2000 vintage computer with a PCI bus. Surprisingly, it still booted XP - but the CMOS battery was dead. I replaced that, installed the controller and was great ted with the familiar CTRL-A to enter SCSI utilities. Step 1, accomplished. My SCSI chain consisted of a ID 6 - an IOMEGA Zip-250, ID 5 - an IOMEGA Zip-100 and ID's 1 and 2 - a Quantum Fireball as emulated by the SD2SCSI. As I was picking up the Zip-100 the plastic windows fell in - apparently Zip drives are rapidly self destructing. That's OK - they where just backups anyway. Using my newly purchased HD-50 pin external to 25 pin SCSI cable - I hooked up the SD2SCSI - immediately both drives found. I took out my ASCSI, cleaned the edge conntectors, tested the fuse (good) and hunted around in my parts box for a couple of hours and found some tie downs for the 25 pin connector. I took the ASCSI and SD2SCSI and reinstalled, same problem. I think my next step is to try the ASCSI in a 4A and see what happens. Fortunately, everything on the ASCSI is in a socket, so I can pull out each chip and run it through the TL-866. Does anyone have the minimem incantation to page in the ASCSI DSR and read the first 16 bytes? 2 Quote Link to comment Share on other sites More sharing options...
