I originally attempted to post this to simh at trailing-edge.com, but they have a policy of automatically rejecting any messages from non-subscribers, and as I only read that list via the Web interface, it doesn't seem worth it to subscribe just in order to post one message. However, I suspect that Brian Knittel and/or Mark Pizzolato probably see stuff that's posted here too. --- Once upon a time (i.e., prior to early January, 2016), the SimH IBM1130 GUI worked like this (on Windows): You start the simulator in a console window and issue the commands (either manually or via a command file argument): ------------------------- reset detach prt delete printer.txt att dsk0 dms.dsk att prt printer.txt boot dsk ------------------------- At this point, the simulator, after having booted the DMS operating system, enters a "Wait state" and drops back to the SimH prompt. The console window shows (if you've started the simulator with the command file argument "guijob" containing the above commands): ------------------------- IBM 1130 Simulator V4.0-0 Beta git commit id: e8ea427d guijob-2> detach prt Not attached PRT: creating new file Loaded DMS V2M12 cold start card Wait, IAR: 0000002A (4c80 BSC I ,00028 ) sim> ------------------------- The line printer icon in the GUI now "shows paper" which, if you view it (thereby "tearing it off" and causing the creation of a new printer file) will show the boot message from DMS. At this point, you can submit a "job deck" by dragging a file to the GUI's card reader icon -- e.g., one of the decks from the software kit at ibm1130.org (such as a job to print the LET [Location Equivalence Table] list.job, a sample Fortran program for.job or one of the more substantial Fortran programs like csort.job or swave.job, etc.) Each time you drag the "job deck" file over the GUI's card reader icon, the depicted input tray "fills up" and the console shows, e.g. sim> attach cr "C:\ibm1130\dms\list.job" sim> You then click the green PROGRAM START button, the blinkenlights flash briefly, the card reader "empties", the printer "shows paper" (if it was empty beforehand) and, most significantly here, **the simulator enters Wait state and drops back to its prompt when the program has finished**. The console window now shows (e.g.) sim> attach cr "C:\ibm1130\dms\list.job" sim> cont Wait, IAR: 0000002A (4c80 BSC I ,00028 ) sim> You can continue to submit jobs, without rebooting DMS, by dragging a new deck to the card reader icon, and clicking PROGRAM START. Each time, the simulator swallows the "cards", flashes the blinkenlights, adds output to the line printer file, and enters Wait and drops back to its prompt. The "git commit id" in the IBM1130.exe used for the above example is e8ea427d from https://github.com/simh/Win32-Development-Binaries archive simh-4.0-Beta--2016-01-07-e8ea427d.zip (January 7, 2016). If I use the IBM1130.exe from the very next archive simh-4.0-Beta--2016-01-29-b8049645.zip (January 29, 2016), I get a different result (using the same file of startup commands): ------------------------- IBM 1130 Simulator V4.0-0 Beta git commit id: b8049645 guijob-2> detach prt Not attached PRT: creating new file Loaded DMS V2M12 cold start card ------------------------- Here, the simulator has not entered a Wait state and dropped back to a prompt. If I try to drag a "job deck" file to the card reader icon, the attempt is rejected with a Windows error gong and the card reader remains empty. I can get around this by performing the following: Click the red "IMM STOP" button. Drag the "job deck" file to the card reader icon. The reader "fills up". In the console window, type "boot dsk" to re-boot DMS (clicking PROGRAM START doesn't work here!), The card reader empties, the blinkenlights flash and apparently the program runs. However, the simulator does not enter Wait state when the program is finished. (Nor can I click on the lineprinter icon to "tear off" and view the results at this point.) However, if I again click the red "IMM STOP" button and then click the lineprinter icon, I can see the results of the program that just ran. Or, I can click IMM STOP, submit a new job deck to the card reader, type "boot dsk" (you have to re-boot DMS; PROGRAM START won't work!), and the new program will run and add its results to the lineprinter output. The very latest Win32 build of IBM1130.exe, from simh-4.0-Beta--2017-05-02-e9dea63b.zip (May 2, 2017) exhibits slightly different (but still apparently broken) behavior. When the startup command file executes, the initial result looks correct (i.e., the same as the January 7, 2016 result above): ------------------------- IBM 1130 Simulator V4.0-0 Beta git commit id: e9dea63b guijob-2> detach prt Not attached PRT: creating new file Loaded DMS V2M12 cold start card Wait, IAR: 0000002A (4c80 BSC I ,00028 ) sim> ------------------------- Note that the simulator has entered the Wait state and dropped back to its prompt, and you can now drag a job deck to the card reader and start the program normally by clicking PROGRAM START. However, at this point the simulator reverts to the broken behavior exhibited by the January 29, 2016 example above -- when the program is finished running, the simulator does not enter Wait state and drop back to a "sim>" prompt. The console window looks like: ------------------------- IBM 1130 Simulator V4.0-0 Beta git commit id: e9dea63b guijob-2> detach prt Not attached PRT: creating new file Loaded DMS V2M12 cold start card Wait, IAR: 0000002A (4c80 BSC I ,00028 ) sim> cont ------------------------- and the simulator remains unresponsive until the IMM STOP button is pushed. Then we see: ------------------------- IBM 1130 Simulator V4.0-0 Beta git commit id: e9dea63b guijob-2> detach prt Not attached PRT: creating new file Loaded DMS V2M12 cold start card Wait, IAR: 0000002A (4c80 BSC I ,00028 ) sim> cont Immediate Stop key requested, IAR (4c80 BSC I ,00028 ) ------------------------- At this point, the GUI becomes responsive again, and the line printer output can be "torn off" and viewed, or a new job can be dragged to the card reader. However, you cannot then use the PROGRAM START button to start the new program. If you do, the simulator will issue a "cont" command, but the card reader will not empty and the new program will not run. You have to type "boot dsk" in the console window to reboot DMS. At this point, the loaded card reader will empty by itself, the new program will run, and the program's output will be added to the lineprinter listing. For each additional job deck you want to run, you have to use the IMM STOP, load card reader, "boot dsk" (reboot DMS) sequence. So it appears something happened to break the normal functioning of the 1130 GUI back in January of last year, which has not yet been completely repaired.

Panel ID?

Cory asks: > http://www.radar58.com/panel/ I had always thought Transistor Electronics Corporation had something to do with CDC (both in Minneapolis) but CHM tells me I was wrong: it was a spin-off from Univac: http://www.computerhistory.org/brochures/companies.php?alpha=t-z&company=co… Tim.

SimH IBM1130 GUI appears "fixed"

It was one of many programs distributed by Share to 1130 users, thus it was contributed by somebody. Carl

Panel ID?

by coryheisterkamp＠gmail.com

Can anyone ID what this panel is from? I picked it up recently for parts but the more I study it the more I suspect it may have been part of a computer system. At least one status light references 'No Write Ring'. The displays at the top are terrific, 7-segment incandescent units! Photos at: http://www.radar58.com/panel/ Thanks, Cory

Hershey Fonts now 50 years old

by tshoppa＠wmata.com

I grew up with X-Y scope displays, their associated electrostatic printers, and Calcomp pen plotters. To draw letters and symbols on these, we used Fortran libraries driven by data tables to make "Hershey Characters". This year, the Hershey Font system and libraries turn 50 years old: https://books.google.com/books/about/Calligraphy_for_computers.html?id=qFFC… A little more context: https://en.wikipedia.org/wiki/Hershey_fonts Happy Anniversary, Hershey!

Morrow 8" disk image CP/M uploaded

by billdegnan＠gmail.com

Hi, I was contacted though my site by someone looking for a boot disk for their California Computer System S-100 2200 computer with Morrow's Disk Jockey DJ/DMA floppy disk controller. I checked and found what might be a suitable disk. I imaged the disk and the file has been uploaded to my web site along with a PDF of the directory the original owner printed and inserted into the disk sleeve. Does anyone have such a drive controller and would like to take a look at this image to see if it's usable? Uploaded, here: http://vintagecomputer.net/disk_images/Morrow/ There may be something wrong with the disk. The label reads 8" Morrow E14 Phil's System Disk Backup 9/22/86 Permanent error on boot track Despite what was printed on the lable I was able to image the disk without error. I am hoping the error referred to in the hand-written label is not a physical error and can be edited/corrected. Maybe this disk is salvageable, maybe the error is a BIOs thing. There was talk about trying to find a diskJockey boot disk on this list a few weeks ago (right?), if so I hope this is useful. If anyone attempts to read, let me know how it goes. Bill
