The only physical Component for my 8-Bit 6502 computer project is a Windbond W27C512-45Z EEPROM. While reading the Datasheet for it, the OE/VPP (Pin 22) is used for several different things, Including the Read and Modes. I do not want to use the Erase Mode, I only want to use the Read Mode so the CPU can read the Machine Code stored within the ROM.

So what do I do with the OE pin? Do i just tie it low so the Output Enable is always active just like an ATMEL EEPROM?

Bonus Question:
I'm also using a AS6C1008-55PCB 128k SRAM IC, What should I do with the OE pin on it as well?

What's an additional VIA among friends, anyhow?

What happens when I pull OE/VPP to ground? Is that going to destroy the chip? And what happens when there is no voltage going into that pin?

From what I understood, it should be connected to +5v so it won't erase the Program data, so should I tie it to +5V, Ground or leave it alone entirely?

Use the pipe or exclamation mark for NOT if overline isn't possible: |OE or !OE. Any mutually agreed upon convention will do.

phpBB apparently has an overline BBCode, the letter O in square brackets. vBulletin appears not to have it. Someone familiar with the PHP source code could add it though:

There's likely more to it than that. The message parsers on these forum packages have to do a lot of gymnastics to handle nested tags, fix tagsets that the user forgot to close, etc. This would have to be done by someone invested in the package. I'm not the one. PHP forum code looks like spaghetti code to me.
