Oak Tech OTI VGA Utilities and Drivers
A collection of drivers and utilities for Oak Tech OTI VGA cards, for DOS and for Windows. These files are from various sources, but are all useful for owners of Oak Tech cards, such as the Oak Tech OTI-037C based card that I tested these with. ** The utilities provide VESA Bios Extensions, as well as tools for setting video modes manually. Also useful for testing Oak Tech ISA cards, if you have them. ** The drivers provide better support for Windows 3.1.

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/

PALASM2 2.23 2 2.23
Rare software to design microchips and 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. The newer version palasm4 1.5 has a completely different user-interface. This version is even harder to get than version 4. It's from the wayback-machine's software-archive. Therefore I don't know if it's virus-free. There are only three programs like palasm: WinCUPL, Opal and Opaljr. Since GAL-chips are not used anymore in industry, there is no new software for them in present time.
