QBUS SCSI controller for RT-11

DON'T buy that KZQSA for your PDP-11. I made that mistake. I paid $45 for one on eBay. When I got it, behold, it would not work. I then looked high and looked low, but there are no drivers for this board for any PDP-11 OS. I even looked through the VAX NETBSD source code to see if I might want to port it, but I could not find it there either. It is my understanding that this board is supported only under VMS. What you want is an MSCP compatible board; the KZQSA is not. Fortunately someone with a VAX bought it off me for the same price I paid for it, so I was only out the shipping. I tested a Viking QDT with RT-11 and a 1 gig HD. Of course, I could only use the first 30 megs. This one is destined for a BSD machine anyhow. I got the QDT for $45 on eBay. Someone put it up with a buy-it-now of $45. Someone tipped me off, and I got there first. It pays to keep a sharp eye on eBay. I just bought a KDJ11-SD off eBay for $5. This is a nice one: rev -09 CPU, 18 MHz, 1.5 megs RAM. Other recent eBay steals: RQDX3 for $10, DESQA for $8.50. While you are waiting for your dream SCSI board to show up, there are two Maxtor XT1085 in that box lot that is on eBay right now. (The seller mistyped it as KT1085). This drive is physically identical to the RD54 externally. I have been able to use an XT1140 in place of an RD54, I think the XT1085 will work also. You have to hack ZRQCH0 or format it on an MV2000. Two of them would give you the same amount of storage as one RD54. -- Jonathan Engdahl http://users.safeaccess.com/engdahl "The things which are seen are temporary, but the things which are not seen are eternal."
