Hello, recently i came accros a pair of atari 8 bit computer carts.

If someone can tell me what this cartriges are, they have eproms inside and white silver pcbs.

on the pcb says:

1982 eastern house v2 BG83 front

on the back says rear RC

on the labels says:

PROMOVISION VIDEO DISPLAY CORPORATION (212) 0969-8101

the sticker over the screw hole says 2.3 8X

here are the photos:

Just a word of advice...you don't want to expose those EPROMS to light and definitely don't use a camera flash on them. They are sensitive to light exposure.

 

They are sensitive to Ultra-Violet radiation only, like sunlight and some interior lightning, There's no UV in LED- and bulb-based camera flashes.

False...I have seen it happen just from overexposure in a well lit room. Flashbulbs can definitely destroy an EPROM as well.

 

http://en.wikipedia.org/wiki/EPROM

 

QUOTE: "A programmed EPROM retains its data for a minimum of ten to twenty years [5], with many still retaining data after 35 or more years, and can be read an unlimited number of times. The erasing window must be kept covered with an opaque label to prevent accidental erasure by the UV found in sunlight or camera flashes."

 

QUOTE: "Some microcontrollers, from before the era of EEPROMs and flash memory, use an on-chip EPROM to store their program. Such microcontrollers include some versions of the Intel 8048, the Freescale 68HC11, and the "C" versions of the PIC microcontroller. Like EPROM chips, such microcontrollers came in windowed (expensive) versions that were useful for debugging and program development. The same chip came in (somewhat cheaper) opaque OTP packages for production. Leaving the die of such a chip exposed to light can also change behavior in unexpected ways when moving from a windowed part used for development to a non-windowed part for production."

Any chance of getting a dump of this cart?
