RE: [pups] Disk query on Ultrix 3.1

Kevin, a Nice, I have one too (an UC08, which is just a dual-port version of the '7). Yup.. come to Holland, attend one of the 6-weekly "dump" shows, and find yourself loaded with 1 and 2GB drives for a couple of bucks... from Ultrix will think it is an RA81, most likely. The controller will be seen as either an RQDX3 (MFM QBUS) or an UDA50 (MFM Unibus). Never tried that, 'cos the controller is still on my "todo shelf". Drives attached to either will report as RAxx'es... I have a kernel with "RA99" compiled in. That is a test for my experimental support for Ultrix-32-like "partition tables" (/etc/chpt et al). Works OK so far... Anyway. Uhm, your drive most probably should work fine when referred to as an RA81 on an RQDX or similar.. UDA50 comes to mind.

That is, no equivalent of the RQDXn exists for Unibus. Disks on the RQDXn reports as RDxx or RXxx, while disks on the [KU]DA-50 reports as RAxx (from a hardware point of view). They're both MSCP controllers though. Johnny Johnny Billquist || "I'm on a bus || on a psychedelic trip email: bqt(a)update.uu.se || Reading murder books pdp is alive! || tryin' to stay hip" - B.

The UC0x talks MSCP (and/or TMSCP, if configured) on the Qbus side, and SCSI on the device side. I have an UC08 which is configured for MSCP on bus 0, and TMSCP on bus1. The attached Exabyte 8200 (2GB) is seen as a giant TK50 :) That was on the MVII, though.. havent used it since. Was going to put it in the 11/83, _if_ I can find a BA123. Anyone got one of those laying around? :) Cheers, Fred ********************************************************************** This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.
