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
