Free 1970 roadrunner airgrabber software for mac

Pachyderm is a small utility that quickly checks your system clock to make sure its sane. This can help workaround the occasional problem where a machine has its clock reset to January 1, 1970 after rebooting.

To use it, simply run it. If Pachyderm thinks your system clock is screwed up, it will ask you to change or confirm it. If the system clock seems OK, Pachyderm will exit without any user action.

One good use for Pachyderm is to put it into your login items so that it runs every time you log in (and, by extension, every time you reboot).

Requirement: Mac OS X 10.4 Tiger

Mr. Tides is a tide and current prediction program, based (loosely) on the X-Window program "XTide", but written in REALBasic, not C/C++. Mr. Tides can read the harmonics and offsets files used by XTide, so it is what XTide calls a "non-port".
Mr. Tides uses a map interface to show tide and current stations all over the world (except the United Kingdom, which does not want anyone predicting their tides). By clicking on these stations the day, week, or month tides or currents can be displayed for any date between 1970 and 2037.
As with all navigation software, you should not depend on this program as your sole means of navigation.
The wise navigator uses all sources possible.
Mr. Tides uses the tide algorithm and data derived by the U.S. Government, so the output is a prediction. It will sometimes not be accurate. Use at your own risk, and keep in mind that it may not match reality.
Enhancements:
- Updated the DST settings to use the new US time changes.
- Fixed a display problem with substations when DST starts.
- Fixed a display problem with the week view where the moon would be in the wrong location

The PDP-8/E Simulator is an emulator for the Digital Equipment Corporation PDP-8/E minicomputer, a famouse computer of the early 1970 years. The simulator, first released 1994, provides a comfortable user interface for running, writing and debugging PDP-8 software on a Mac and to learn about the internal functioning of a computer.
It has a console with switches and flashing lights enabling the user to operate the PDP-8 like a hardware machine. Maybe the simulator is of interest for a larger audience using it for educational purposes or as a remembrance to the good old time of the computer age.
The simulator and its source code are published under the GNU General Public License.
Enhancements:
- The version 1.5 release includes a TSC8-75 board that enables the emulated PDP-8/E to run the ETOS time sharing operating system.
- Compared to the version 1.5 public beta, there are only minor user interface and Panther compatibility improvements.

Game of Life was invented by the Cambridge University (now at Princeton) mathematics professor John Conway. His "rules" were first published in the October 1970 issue of Scientific American. Life is likely the most frequently programmed computer game.
What does our application have thats better than the others... a great icon! And thats about it. This application allows you to set up cells and then watch what happens as they follow the rules of the game through multiple generations.
There are a few built in designs as well as the ability to save and reload your own. If you find this application interesting then do yourself a favor and search out one of the many much more thoroughly written Life programs.

System requirements:
- 640 x 480 or greater screen resolution

XLogo is a LOGO learning and drawing application. LOGO is a dialect of Lisp, and was first developed in the 1970s to be used as a teaching language. XLogo implements a subset of this language, it is freeware, open source, and is designed to be easy to use.
