BA23 setup and DZQ11 configuration

by dbetz＠xlisper.com

I'm starting to collect some qbus equipment again and am trying to setup a system around a KDJ11-AA CPU. My current configuration is: BA23 enclosure KDJ11-AA (m8192) MSV11-QC (m7551 cf) DZQ11-M (m3106) RQDX3 (m7555) TQK50-AA (m7546) First, will it be possible to boot this configuration? Can I setup to start the KDJ11 in ODT mode and enter a bootstrap for the RQDX3 by hand? How long a program would I have to enter? Also, I've done a Google search but have been unable to find documentation on how to configure the DZQ11 module. I'd like to configure it so that I can use one of its ports as the console port for ODT. Is that possible? I'm planning on using a Maxtor XT-2190 190mb hard drive. If that won't work, I have a number of RD53 drives I can use instead. Is this a workable configuration or do I need a boot module like the MXV11? Thanks, David

A good substitute for RX50 is an RX33 (aka TEAC FD55GFR) or an FD55F setup as non1.2mb. RX50 drives are actually two platters but one head positioner and they are 96TPI like the mentioned FD55F or G. These work fine with RQDX2/3 as a RX50 substitute. I have one configured that way. Allison

2708 EPROM progreammer - old magazines designs

by john_a_s2004＠hotmail.com

Hi, I am thinking of building a programmer for the 2708 EPROM, that can also read an EPROM and dump it to a serial port. As 2708s are obsolete few moern programmers support them, apart from a few that cost many $100s. So I thought why not try and build one? I've found references to the following classic magazines, and I would be willing to pay a small fee for photocopies or scans of the articles: Program your next EROM in BASIC. Schematic for a 2708 erasable read only memory reader and programmer which uses parallel IO ports to set data and address. The software to drive the programmer is written in BASIC. Byte - March 1978 page 84 on (main article) Byte - April 1978 page 62 (Byte Bugs) How to program 2708 EPROM's using this circuit board and program. Byte - April 1980 page 198 on (main article) Byte - September 1980 page 321 (follow-on) A Simple 2708 EPROM Programmer ... For the Motorola D2 kit ... Frank W. Summers. Kilobaud - February 1980, page 138 (magazine is currently on eBay) #638 2708 EPROM programmer. Electronics Today International (ETI) - July 1978 Instead of money I can provide (or copy / scan articles) any of 24 issues of Byte from 1981 to 1997 (including 11 issues from 1986) which I don't want to keep. or I can photocopy / scan articles from nearly any copy of Practical Computing from 1978 to 1985 (which I do want to keep). If you have built your own design of 2708 programmer and want to share that would be great too.

Nicolet NICE Z80 Hardware emulator

by doug＠stillhq.com

Hi Guys n Gals, Just a quick second request, Does anybody have a manual - or even a quick reference sheet - for the Nicolet NICE Z80 Hardware pod released in about 1980-1981. I just received one, and there was no manual. I've figured out some of the commands, as there are only 26 letters in the alphabet, but a photocopy or scan of the book, or a quick summary from somebody else, would be invaluable. Take care, Doug

AlphaStation 200/250 and 255 - ebay observations

by ddsnyder＠zoominternet.net

AlphaStation 500's are less expensive, but be aware the memory is unusual. Form factor 168pin dimm, 5v, FPM. The machine has two banks, each requires 4 dimms per bank. I have not been able to find any of these dimms. The AS500/400 I currently have, has both banks filled with 8x64M dimms (512M), the way it was configured when I received it. Dan @ Butler, PA

Speed of text editors on 808x platform

by trixter＠oldskool.org

I spent the weekend obsessing over what the fastest editor I could find for a 4.77MHz 8088, DOS, CGA platform. The results, if anyone is interested, are here: http://www.oldskool.org/guides/texteditors No doubt I will get some scorn for knocking Brief and other venerable editors, but the truth is I have very specific needs: 1. Instant screen response to user input, and 2. a functional undo. That's it, really, and I was surprised how many text editors did not fit the bill. -- Jim Leonard (trixter at oldskool.org) http://www.oldskool.org/ Help our electronic games project: http://www.mobygames.com/ Or check out some trippy MindCandy at http://www.mindcandydvd.com/ A child borne of the home computer wars: http://trixter.wordpress.com/

2.11BSD source code browser and xref --> css and IE 6

I got some feedback about problems with the css style file I use and IE 6. Due to an oversight three named colors not known to IE 6 were used, I fixed this. Now all text is at least visible. There is still a problem on some pages with IE 6 on the first code line (e.g. /usr/src/sys/h/errno.h). With firefox all looks fine, but I'll try to make it render on all browers.

GOTO (100,200,300),J I used Fortran 4 on the IBM 7094 at Imperial College London. I remember one day the compiler reported: FORMAT MISSPELLED ON LINE xxx FORMAT ASSUMED. I was used to syntax error messages by the dozen but this was the first time I had seen the compiler correct an error and run the job. Of course we are used to warnings now, but I think it was that one which got me interested enough in compilers to eventually get a job writing them. > At one point in time, given machines with different character sets > and word- and character sizes, FORTRAN was about the only way to > write a portable program.

Yes, my ICT1301 (155+ built from 1962 to 1965) had no Fortran compiler. But then the line printer did not have any sort of parentheses. Not () [] or {}. It had 1/4,1/2 and 3/4 though. I have a replacement print barrel with round brackets instead if the 1/4 and 3/4 symbols but I have not fitted it yet, and most 1300 series machines had the standard barrel. I seem to remember that some of the people who taught me to program considered Fortran to be too close to the 7094 instruction set, in particular they said the computed goto mapped directly onto a 7094 instruction and hence considered it to be not very universal, and to support it would be to assist IBM in its domination of the computer market. Not that I think that way, and of course it is Microsoft which now dominates the computer market, I haven't seen a new IBM machine in years. > IIRC, that was a big selling point for the PDP-8. > > There was a period in time where just about any serious programmer > had a copy of McCracken on their bookshelves. Maybe before my time (BSc Computer Science graduated 1974), but I think most serious programmers had a copy of Knuth vol 1.

On the subject of being afraid to touch code, I worked on a compiler written in a non recursive language (Coral 66, a real time language derived from Algol 60). It had a large data table which defined how to parse the language. The compiler had an array of integers which was really a stack, but instead of return addresses it had integers which referred to cases in a huge switch list. I was happy to change any of the code, but fortunately did not need to change the data table for a long long time, and when I did it was with EXTREME care and trepidation.

Dec TU81 tape drive issues

by ian_primus＠yahoo.com

After cleaning and checking it out, I fired up my newly acquired Dec TU81 tape drive today. It gave an error code of E56 on the front panel. I tried clearing the error, and loading up a reel of tape and hitting the Load switch. It makes a whirring noise, and the take-up reel turns a small amount, then it shuts off - the Logic Off light lit. So... looking in the manual on bitsavers, it looks like E56 is a servo control sort of error. Before I start tearing into this drive in what may be a dead end at a bad motor, I figured I'd ask the experts here - Am I looking at a bad servo, or is this some known failing capacitor/regulator/fuse sort of a problem? Thanks! -Ian

Archival plotting on mylar

by ethan.dicks＠gmail.com

I was researching how best to plot out a map or two on my HP Draftmaster II, when I ran across a page about plots and storing them for decades as surveyors are required to do... http://www.aocweb.org/surveyors/archival.htm It got me to thinking about my own project - essentially a map on a light box (there's more to it, but that's all the map is about). I was thinking of plotting on mylar, but I was unable to find any HP plotter pens with permanent ink for anything other than paper. Has anyone on the list here had to do any archival plots for surveying? I'm sure that whatever products they are using would be more than sufficient for my purposes. Thanks for any pointers, -ethan

Mostek MK3881 PIO controller manual

by julesrichardsonuk＠yahoo.co.uk

Does anyone know if the above is identical in spec to the "official" Zilog PIO chip? The manual's dated November 1976 and stamped as preliminary, which is a little unsettling :) I want to do some messing around with a Z80 CPU and PIO, and having a physical paper reference to hand would sure be useful - I'm just not sure if I'm going to shoot myself in the foot using this particular one! I should go and google for Zilog / Z80 history I suppose to see where Mostek fit into things - I've got a rather thick Mostek UK Z80 programming manual (V2.0) too which would also make a useful reference, assuming it's sound for all Z80 chips regardless of source... cheers Jules

Good point, _main deserves indeed extra treatment. The startup code is by the way in http://www-linux.gsi.de/~mueller/test/211bsd/usr/src/lib/libc/pdp/csu/crt0.… with the call to _main in line 124. > That's about all I can come up with except to wish that when the tool > is in better shape that someone has the time to run 2.9BSD sources > through the same treatment (2.9BSD still runs on non-Split-I&D > machines like those equipped with an F-11 chip - 11/23, 11/24, > Pro350). > > -ethan This is indeed the intention. The rules to locate include files, to link globals, or to decide what is kernel, lib, or user, is in a configuration file. To set this up for 2.9 BSD or UNIX V7 and V6 should not be difficult, in particular if one starts with the more complex case and goes back in history. With best regards, Walter -- Dr. Walter F.J.

Speed of text editors on 808x platform

by sdc695＠yahoo.com

All this talk of editors on PCs got me to thinking of my favorite: PC-EDT It was a clone of the EDT used under RSX-11(-M). Pretty faithful as well. It had problems with the keypad, being that the '+' took up two key spaces (as opposed to the standard VT-100 keypad), but overall it was nice. It even worked on old XT's and scrolled pretty fast. If you happened to do large Cut/Pastes it took some time as it swapped out the buffers to temp disk files. I still use the editor to this day after first using it in the 80's. The old keypad layout is pretty ingrained in my mind. EDT (on RSX-11) was my first screen editor, so I guess you get used to your 'first'. Unfortunately, vi seems everywhere, and as everyone knows knowledge of vi is almost mandatory for any person using Unix (Linux) (even today). Thankfully I haven't succumbed to emacs (and hopefully never will, even as the spell checker wants to capitalize the first letter!). -- Tom Watson tsw at johana.com ____________________________________________________________________________________ No need to miss a message.
