Wecome To The New Home Of TheEPROM9
Looks to be an old 70s Intel 24 pin 1KB chip.
An EPROM from the former Soviet Union & trying to go back to being Soviet Union. It is a 1KB chip & 24 pin.
An 28 pin 32KB Intel chip from the 80s. From an old photocopier.
These types of EPROMs are pretty much non-exsistant to find in the wild. Found one a long time ago now in an old mobile phone, sadly broke it. It is a 32KB chip from 1996. I have 5 of these, 4 of them are still in there original packaging.
Not sure the capacity of this EPROM, looks to be from the 1970s, the numbering stranded does not match any modern systems.
A 24 pin 2KB chip from 1979. Pulled two of them from some vintage network cable testing equipment. Programed one of them to be a ROM for my Acorn System 1.
Texas Instruments 28 pin 8KB chip from 1988 pulled from an old MDF HDD controller card.
Texas Instruments 24 pin 4KB chip from 1987.
Two of these on display, 24 pin 2KB chips from 1983, not sure who the manufacture is.
National semiconductor 24 pin 2KB chips from 1985. I have two of them, got them for the Acorn System 1 project.
A ST Microelectronics 28 pin 32KB EPROM. I have 4 of them, all from 1999,They came from an old 90s CCTV control unit. Had most of my EPROM's for years now.
ST Microelectronics 32 pin, I think 256KB chip from 1996. I have two of them.
Texas Instruments 40 pin EPROM, not sure the capacity, But I think its about 2Mb. It was from some old laser printer boards from the 90s
A EPLD from ALTERA that looks to be from 1988, probably the granddaddy of the modern FPGA.
ST Microelectronics 32 pin, I 256MB chip from 1996. Probably actually have three of these, not two.
ST Microelectronics 32 pin, I 256MB chip, not sure the year, probably late 90s to early 2000s.
ST Microelectronics 32 pin 128KB chip from 2002. Probably my newest EPROM. I got given this one back in school when someone was working on the cash to smart card machines. Apparently he did not need it, so he let me have it after I took interest. Here I am 20 years later & I still have it.
ST Microelectronics 32 pin 256KB from 1998. I seem to have a lot more of these EPROM's than I thought. This one is from 1998.
Hitachi 32 pin 128KB chip from 1999. I think this came from an old 90s scanner.
National semiconductor 28 pin 16KB chip from 1995.
Hitachi 28 pin 64KB chip from 1992.
ST Microelectronics 28 pin 32KB chip from 1992.
Texas Instruments 28 pin 64KB chip, not sure the date. This EPROM was pulled from a car ECU that was obtained from a scrapyard. Not sure what car it was pulled out of. Should do a ROM dump of it.
National semiconductor 28 pin 64KB chip from 1994.
ST Microelectronics 28 pin 23KB chip from 1997. I think I got this one from a control panel from a photocopier.
MX 28 pin 32KB chip from 1997.
ST Microelectronics 28 pin 32KB chip from 1998. I have two of these chips.
An NEC 32 pin 512KB chip from 1991. Pulled from an industrial computer board from the uni WEEE bin.
A Intel 24 pin 2KB chip from 1977. Was a dead unit that would not erase under UV-C so it was not used to repair a Kaypro II.
A National Semiconductor 24 pin 2KB chip from 1981. This chip was the graphics ROM in a Kaypro II, however it had failed in such a way it would read different data with each read.
ST Microelectronics 32 pin 256KB from 1997. Pulled from an old printer CPU card.
AMD 32 pin 512KB from 1990. Pulled from an old printer CPU card.
ST Microelectronics 32 pin 256KB from 1997. Pulled from an old printer CPU card.
