Onesimus - A Quest For Freedom 1.5
You are Onesimus, a slave of Philemon. You want to escape from slavery and be free. For freedom you must go to Rome. There you must find the apostle Paul. He will teach you how to become a Christian. Only then will you discover true freedom. This game uses the Jill of the Jungle engine. Just like in that game you must find keys to open doors, apples to maintain your health and knifes to ward off dangerous animals. Included is the full installation folder as well as the CDROM image if you want to view the installation setup.

OPALjr 2.01 2.01
Rare software to convert logical equations to JEDEC-files. These files are neccesary to burn PAL- and GAL-chips. With a programmer, someone can change these chips internal logic-gates to design whatever kind of microchip is intended. This software includes two extremely rare tools in addition: a) a program to convert a jedec-file back to a textfile which contains logical equations (JED2EQN.EXE) b) a program to convert PAL-jedecs to GAL-jedecs (PAL2GAL.EXE). OPALjr was the free "light-version" of OPAL. The manual reads: "OPALjr is a functional subset of the full OPAL package. It is designed to: a) provide free low-level entry design support for all NSC low-density PAL and GAL devices b) demonstrate the syntax and capabilities of the full OPAL PLD development software package, including support for higher-density MAPL devices." This kind of software is RARE. The only other programs of this kind are: PALASM and WinCUPL. I downloaded it from: http://www.brouhaha.com/~eric/retrocomputing/mmi/palasm/

Open Access 3 3
Powerful integrated suite comprising: Database, Programmer, Spreadsheet, Word Processor, Communications, Applications, Utilities. Has a superb relational database, and buried within the spreadsheet is a statistical analysis module that will make you sweat bricks unless you are a statistician. Minimal graphics, hyper DOS-sy, but extremely powerful with a built in programming language and hypertext manual as well as inbuilt help. Also feature macro generator, a dialing contacts manager (primitive) and pop-up text editor. Inbuilt file encryption too. Amazing software for its day and still gives modern suites a run for their money. Loves a DOS environment, works well with windows up to 2000. OK with XP. Best run in a VM these days
