Message-ID: Hi, I have a little problem installing 2.11BSD on my PDP11/83. I have a TK50 tape with the distribution and a TK50 drive from a uvaxII. The controller board is a M7546 that comes from another vax. The original tape drive in this PDP is an TK25 drive which I have disconnected. How should the TK50controller be strapped? The TK25 answered at 17772520. Should the TK50 be there as well? (I haven't got a clue howthe QBus works... I know it's some kind of cascading thing though so I guess it matters in what order the boards are placed in the machine) Thanks for any help! -- Jorgen Pehrson HP 9000/380 (NetBSD/hp300 1.3) jp at spektr.ludvika.se DECstation 5000/200 (NetBSD/pmax 1.3) http://spektr.ludvika.se/museum VAXstation 2000 (VMS 5.5-2) Received: (from major at localhost) by minnie.cs.adfa.oz.au (8.8.5/8.8.5) id KAA16303 for pups-liszt; Sat, 18 Apr 1998 10:00:04 +1000 (EST) X-Authentication-Warning: minnie.cs.adfa.oz.au: major set sender to owner-pups at minnie.cs.adfa.oz.au using -f Received: from moe.2bsd.com (0 at MOE.2BSD.COM [206.139.202.200]) by minnie.cs.adfa.oz.au (8.8.5/8.8.5) with ESMTP id JAA16294 for ; Sat, 18 Apr 1998 09:59:58 +1000 (EST) Received: (from sms at localhost) by moe.2bsd.com (8.8.5/8.8.5) id QAA06940; Fri, 17 Apr 1998 16:50:25 -0700 (PDT) Date: Fri, 17 Apr 1998 16:50:25 -0700 (PDT) From: "Steven M.

Should the TK50 That is the correct address for the first TS controller in the system. Despite the name ("TK25") the TK25 is a TS device and not a TMSCP device. > be there as well? (I haven't got a clue howthe QBus works... I know it's No. The TK50 should be at the first TMSCP address which is 172150. You do not have to (indeed, you can not) set the vector on the M7546 because TMSCP devices are 'programmable' - the kernel will assign a unique vector to the controller at boot time.

The primary TMSCP address (where the TQK50 adaptor should go) is 174500. I accidentally gave the address of the first MSCP ('ra') earlier. So if you have both a TK50 and a TK25 the boards should be set like this TK25 172520 TK50 174500 Sorry for any confusion I caused. Steven
