EPROM Colection
Unknown 2708 EPROM
Looks to be an old 70s Intel 24 pin 1KB chip.
Tesla MMB8708C
An EPROM from the former Soviet Union & trying to go back to being Soviet Union. It is a 1KB chip & 24 pin.
Intel D27256J-2
An 28 pin 32KB Intel chip from the 80s. From an old photocopier.
ATMEL AT27C256R
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.
NEC D8755A
Not sure the capacity of this EPROM, looks to be from the 1970s, the numbering stranded does not match any modern systems.
AMD AM2716-IDC
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.
TI TMS2764-20JL
Texas Instruments 28 pin 8KB chip from 1988 pulled from an old MDF HDD controller card.
TI TMS2732A-45JL
Texas Instruments 24 pin 4KB chip from 1987.
ET 2716Q
Two of these on display, 24 pin 2KB chips from 1983, not sure who the manufacture is.
NS NM27C16Q-45
National semiconductor 24 pin 2KB chips from 1985. I have two of them, got them for the Acorn System 1 project.
ST M27C256B
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 M27C2001
ST Microelectronics 32 pin, I think 256KB chip from 1996. I have two of them.
TI TMSJL27C240-12
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
ALTERA EP900JC-2
A EPLD from ALTERA that looks to be from 1988, probably the granddaddy of the modern FPGA.
ST M27C2001
ST Microelectronics 32 pin, I 256MB chip from 1996. Probably actually have three of these, not two.
ST M27C2001
ST Microelectronics 32 pin, I 256MB chip, not sure the year, probably late 90s to early 2000s.
ST M27C1001
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 M27C2001
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 HN27C101AG-10
Hitachi 32 pin 128KB chip from 1999. I think this came from an old 90s scanner.
NS NM27C128Q
National semiconductor 28 pin 16KB chip from 1995.
Hitachi HN27C512AG-15
Hitachi 28 pin 64KB chip from 1992.
ST M27C256B
ST Microelectronics 28 pin 32KB chip from 1992.
TI TMSJT27C512-12
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.
NS NM27C512Q
National semiconductor 28 pin 64KB chip from 1994.
ST M27C256B
ST Microelectronics 28 pin 23KB chip from 1997. I think I got this one from a control panel from a photocopier.
MX 27C256DC-12
MX 28 pin 32KB chip from 1997.
ST M27C256B
ST Microelectronics 28 pin 32KB chip from 1998. I have two of these chips.
NEC D27C4001D-15
An NEC 32 pin 512KB chip from 1991. Pulled from an industrial computer board from the uni WEEE bin.
