>Am I correct in assuming that when a PDP-11/44 finds that it has more than >one controller in it that it can boot off of, that it drops you into the >monitor, so you can select the device you wish to boot from? I think that you're asking "Does the 11/44 have a sniffer boot?" The answer to that is no. The boot device (or "boot to console") is selected by DIP switches near the actual physical boot ROM's on the M7098. See http://metalab.unc.edu/pub/academic/computer-science/history/pdp-11/hardwar… specifically, the file "1144.boot.roms", for very detailed information on identifying the boot ROM's present and how to set the DIP switches to select the appropriate one. -- 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

Looking for an RK05j User

by Jgzabol＠aol.com

In einer eMail vom 8/6/99 3:31:33AM, schreiben Sie: << Having gotten the 11/45 in my basement operational :-) , I'm on to the next step, the attached RK05. As I start towards the next milestone I am wondering if there is anyone on the list that has a working RK11/RK05 combination going. I will likely have questions! >> I do have a 11/34a with RK05Js operational, and I am in the process of attaching a Plessey drive to it, hopefully RK05 compatible. Maybe we run into similar problems soon ! So far, apart from a defective blower motor which needs replacement, I did not encounter any problems with the drives or the packs or the controller. John G.

DUMB VMS!

IBM PS/2 P70-386 SIMM needed...+ a couple other things...

by jolminkh＠nsw.bigpond.net.au

Does anyone I've never heard of this "sets of 2" stuff on these. They use the same simms as the desktop model 70 . . ie with presence detect circuitry. Hans

Morrow Pivot AC adapter- what Voltage??

by cdrmool＠interlog.com

Thanks Sellam, that would be great. It was an exciting find and I'm looking forward to getting on line with this. Hopefully I can change my Karma around modems in portables. Other than my Kaypro's, I've yet to get a modem in a portable or luggable to work. colan colan ____________________________________________________________________ Vintage Computer Collectors List and Info: http://members.xoom.com/T3C Mail us at: T3C(a)xoommail.com -----Original Message----- From: Sellam Ismail <dastar(a)ncal.verio.com> To: Discussion re-collecting of classic computers <classiccmp(a)u.washington.edu> Date: Thursday, August 05, 1999 11:38 PM Subject: Re: Morrow Pivot AC adapter- what Voltage?? >On Thu, 5 Aug 1999, Colan Mitchell wrote: > >> I found a Morrow Pivot at a thrift shop and it gives conflicting information >> as to the voltage needed to run it.

186 (was: CompuGraphics Question)

by peter.pachla＠vectrex.freeserve.co.uk

Hi Tony, >Thought so. I can't remmeber what my Nimbus has in it, and it's >not easy enough to get to it to find out. I _think_ it's a 186, though. Yes, they're right buggers to take apart. We had a few 286, 386SX and 386DX machines too....though I think there was only 1 machine on the site which was a DX. ISTR there was a set of patches included with DOS which you had to run on the '186 machine to switch it to operate in IBM compatible mode. >And what's wrong with Beebs or Apples? For a lot of applications >they're more useful than most PCs. Nothing....they're great machines. Just that with the way PCs have come into fashion in colleges' I was surprised to see them still in use. They were replaced just before I left there....luckily for my collection. ;-) TTFN - Pete. -- Hardware & Software Engineer. Sound Engineer.

Morrow Pivot AC adapter- what Voltage??

by cdrmool＠interlog.com

I found a Morrow Pivot at a thrift shop and it gives conflicting information as to the voltage needed to run it. One spot says 12 and the other says 15. What is the Volt/amp needed? Any other info on it would be appreciated. TIA colan

Old bits (still) free for the taking (UK)....

by peter.pachla＠vectrex.freeserve.co.uk

I still have a few bits and pieces here which I want rid of ASAP....and they're getting perilously close to going in the next skip I come across.... List follows: Wang keyboard. Olivetti wide carriage daisywheel printer (from S100 based WP system) Star NB-15 wide carriage 24-pin printer Princeton Graphics EGA monitor (x2) Nixdorf VDU Televideo 950 VDU (x2) Zenith Z89 VDU The latter items would really only be good for spares, e.g. the Star Printer needs a new printhead, the Z89 is missing the video board, the TV-950s won't communicate with their keyboards, but it's all available for the cost of coming to get it. I'd rather not dump this stuff in a skip but that's where it's all headed and soon if someone doesn't take it away. I'm located in Birmingham, email me directly if interested.
