Anyone have a copy and can scan part 2 of the article on the Dragon 6809 coprocessor for the BBC micro which should be in there? I've got the August copy that has the first part of the article but haven't seen the second part that's supposed to be in the following month... ta Jules

sexy PDP-11/44 panel (was: Re: Original 11/74 front panel)

by henk.gooijen＠oce.com

Without thinking much about it, I'd say that mounting any real blinkenlight console on a 11/44 is *not* trivial! Of course, grabbing UNIBUS address- and data-lines and wiring that to the lights is trivial, but to get all panel functions (LOAD ADDR, DEP, EXAM, etc). working on an 11/44 is more work. I guess there are more people on the list who have a boring PDP-11/44 with a dull panel, that would like to make the /44 more sexy with an 'appropriate' panel. The "upgrade" is, of course, done in such a way that it can be undone ... I (we) do not have a /74 panel :-( , but I'd like to hear what approach you are thinking of, Don. Hmm, you could do it like I did as add-on to SIMH. Hardware with some intelligence reads the front panel and translates the switches to messages in ODT syntax which are send to the 11/44 monitor program ... - Henk, PA8PDP. > -----Original Message----- > From: cctalk-bounces at classiccmp.org > [mailto:cctalk-bounces at classiccmp.org] On Behalf Of Don North > Sent: vrijdag 10 februari 2006 21:07 > To: On-Topic and Off-Topic Posts > Subject: Re: Original 11/74 front panel > > Actually I was thinking of making a replacement/alternate > front panel for my 11/44 using the 11/74 panel. > Add real blinking lights/switches connected up to the real > UNIBUS/memorybus. > > The 11/44 panel is *way* too spartan looking, and the 11/74 > panel would fit just perfectly on the front of the box.

TENEX on emulator (simh?)

by henk.gooijen＠oce.com

Hah, still a good thing that you replied Zane! That last URL was new to me ... but then again, it is quite a new page. Thanks! If I get the 2113E or 2117F console panel working with the Blinklight board set and SIMH, I will let you know!

Such a deal, let the bidding begin ... :-)

by henk.gooijen＠oce.com

Some people don't have any decency at all. Perhaps somebody else, better versed in English than I (me?), could wite him something like: "I was tempted to open the bid at $199, but then I noticed the discoloration by the sun of the spine of the book. The spine should have the same color as the cover. I know that this color turns blue if exposed (long enough) by sunlight. I don't consider *this* book in "very good condition" as you describe in the auction. Thanks, I pass." :-) - Henk. > I sent the seller a message wishing him luck selling it at > that price.

Hi, Sorry to bother you, but I just saw a question you asked on classiccmp.org about programming a 1702 on a Prolog M900 machine. Did you ever get an answer or figured out how to make it work ? Cheers, Serge Roube

I don't have R-E handy, but "Mac's Radio Service Shop" shows up in the May 1955 issue of Radio & Television News. ISTR that it was a regular in the magazine.

11/34a problems continue

by tradde＠excite.com

I don't remember which was missing, either +15v or -15v. It was a long time ago. I removed the one brick and checked that. Checked everything I could. Someone suggested it was probably in the PCB where the power switch is. I removed it, but because of the way it's installed it was hard to check. I happened to have a second one handy so tried it and it worked. It's been running fine since then. --- On Wed 03/08, Julian Wolfe < fireflyst at earthlink.net > wrote: From: Julian Wolfe [mailto: fireflyst at earthlink.net] To: cctalk at classiccmp.org Date: Wed, 8 Mar 2006 18:35:42 -0600 Subject: RE: 11/34a problems continue What was yours doing? > -----Original Message-----> From: cctalk-bounces at classiccmp.org > [mailto:cctalk-bounces at classiccmp.org] On Behalf Of Tim> Sent: Wednesday, March 08, 2006 5:56 PM> To: cctalk at classiccmp.org> Subject: RE: 11/34a problems continue> > > > That's where my problem was for my 11/34a. > > --- On Wed 03/08, Julian Wolfe < fireflyst at earthlink.net > wrote:> From: Julian Wolfe [mailto: fireflyst at earthlink.net]> To: cctalk at classiccmp.org> Date: Wed, 8 Mar 2006 16:23:21 -0600> Subject: RE: 11/34a problems continue> > I just replaced that unit recently, so I really don't think > it's at fault.
