Dear John: If you still have the DEC LA36 Decwriter II please advise. I need one desperately. My last one "died" and I need it for an old computer system. I am in Illinois, but my sons live in southern CA. They could coordinate taking it off you hands. I look forward to you reply Thanks BOB PSYCEDILLO(a)aol.com

Can anybody tell me if a basic application running on an HP87XM will also run on an HP200/300 series Cheers Alec

VMS 4.7 was VAXstation 3100 history (Was ... different)

by truthanl＠oclc.org

Zane, Do you stay with DEC OEM Model NUMBER on replacement? What utilities exist to help identify drives to a MicroVAX? Can I "dummy" some CYL/SPT/Hd count and hand it to the MicroVax and have the OS Come in later and claim its an RD5? something provided the figures match? Like, Whats the difference between a Quantum Q-540 and a DEC RD52? Since Allison Parent mentioned that the RD52 was a Q-540, I have looked it up in "The Hard Disk Technical Guide" by Micro-House. All the details are there. If I were to Find a Micropolis or CDC drive that fit some larger DEC equivalent on CYL/SPT/Heads MFM ST506 RPM etc what would stop me from generating a workable drive profile? Anyone done this? -----Original Message----- From: Zane H.

Thanks for the thread. I have I Plessy 6700 PDP 11/24 work-alike, But its native drive is SCSI. I will Check into alternate controllers / formatters. DEC Model numbering is greek to me Sincerely Larry Truthan Yeah, sure, folks have been doing this for about a decade and a half. See, in particular, ftp://ftp.spc.edu/third-party-disks.txt At a minimum, before getting any further, you're going to need some way to format arbitrary MFM drives to what the DEC controllers will expect for a low-level format, either a VS2000 with its built-in console formatter, or one of the DEC XXDP formatters (ZRQB for the RQDX2, ZRQC for the RQDX3) and a PDP-11 to run them on. -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927

RZ56 Help needed

Some DEC drives do have a jumper to select spinup on power-up, but the RZ23/24/25 definitely don't (the original Connor drives do, but DEC changed the firmware) and some notes I have here suggest the RZ55/56 have different firmware too. What you'll get out of the drive depends on what the OS is trying to do: a SCSI MODE SENSE command will work fine, but you won't be able to do anything more interesting until the disk has spun up (which is done by issuing a START UNIT command). DEC used to have a utility called RZSPINUP to do this, but any SCSI utility that can issue a START UNIT command would do as well. -- Pete Peter Turnbull Dept. of Computer Science University of York

>It has been suggested that there might be a jumper to tell it to spin up >automatically. Does anyone here know if that is the case, and if so, >where it is? As an alternative to my previous suggestion, I've seen frequent mention over the past decade or so in the DEC-related newsgroups to a program called "RZSPINUP". Whether this can be pressed into service under NetBSD, I don't know. (I was under the impression that RZSPINUP ran on a DOS-based PC-clone.)

hmm, i didn't mention paper tape. I have printouts of a bunch of programs from the HP2000F system from my high school days. mostly thermal paper stuff. To the few who have requested it, I will dig the stuff out and make it available. somehow. just give me a couple of days to find it. kelly In a message dated Fri, 3 Dec 1999 1:54:04 PM Eastern Standard Time, "Zane H.

TK50 orientation?

On Dec 3, 15:11, Daniel T. Burrows wrote: > If they are only supposed to be horizintal then you can't put them in a BA23 > in a pedistial configuration. My TK50 User Guide (EK-OTK50-UG-004) shows them in both TK50-D standalone (horizontal) and BA23 (vertical, on their left side if it makes a difference) cabinets. My DEC-original MicroVAX in a BA23 has a TK50 on its side; it was a standard configuration. -- Pete Peter Turnbull Dept. of Computer Science University of York
