| The IBM 7094 (free system available from... see url below) (a horizontal dial program) There are several simulators for the IBM 7094, the one I opted for is at:- http://www.members.optushome.com.au/intaemul/Emul7094.htm Download B709430D.ZIP and unzip it, and copy over my files in the ZIP below and let it overwrite what it wants to. Then run the start up BAT file, and the simulator will compile and run. While this is a free system born out of the love for an old machine, please let the developer know you like his product. This is a complete system, namely the simulator, and IBSYS operating system along with FORTRAN II support. Useful materials may be found at:- http://www.bitsavers.org/pdf/ibm/7094/ A22-6760_7094model2.pdf system summary A22-6703-4_7094_PoO_Oct66.pdf principles of operation Simon's IBM 7094 notes These discuss operating the IBM 7094 simulator, some hints on using FORTRAN II which differs slightly from later versions. Simon's FORTRAN II code for the h-dial, and control files to simplify compile and run on the simulator. The object deck for the program is here also, although the control file will cause a re-compilation and then re-assembly of the source. Tested April 26, 2009 on Vista Win64 as well as XP Win32. I programmed the IBM 1401 back in the mid 1960s before moving on to the IBM 360, then later the IBM 370. I did not program the 7090 series, but I did study it. This program uses SIN/COS because TAN is not supported. This program has the latitude, longitude and reference longitude built in, as I haven't figured out how to read that data yet, I am working on it. So, just change those figures. Also, this program does run on the free FORTRAN system mentioned on this web site. This is presented merely as an echo of what programming was like over 40 years ago. If you like FORTRAN II, then you may want to check this FORTRAN IV page. |

| Illustrating Time's Shadow ISBN 0-9765286-8-1 plus 0-9765286-9-X Lib Cong 2005900674 plus 2006930654 Merges Illustrating Shadows and Illustrating More Shadows, deletes duplicated material, and techniques that are complex and replaced by easier methods, adds new material. Hands on, empirical, geometric, trigonometric, CAD, and spreadsheet dial design for small dials plus garden dials using common masonry supplies, clay, and glass, with emphasis on many calendar line techniques, and inclined decliners, while providing details on the use of DeltaCAD programming including the animation of many sheets as parameters vary. Case studies abound with associated problems solved, and cover the infamous inclined decliner, as well as all the other kinds of outdoor dials. The printed book comes with a CD of booklets, spreadsheets, VRML/WRL files, templates, etc with the printed book. The CD has all books and booklets and programs along with source code. You can get the printed book and CD, just the CD, or an online download here. |
