USB Programmer for EPROM 27C, (27C256, 27C512, etc.)

Product Information

Universal 48-pin programmer with USB 2.0 and parallel connectivity. Dataman 48UXP features intelligent hardware, including microprocessor and FPGA, allowing it to program devices you use today and the devices of tomorrow... If you have the original files, there may be tools to describe programme flow (this will depend on the specific processor / controller).

And we can finish off by moving the /WE connection from Arduino pin D13 to pin A2 and adding connections from A1 to /OE and from A0 to /CE. Willem programmers appear popular (fig 2). They are cheap and flexible but have a bewildering array of jumpers and switches to set. Later the decreased cost of the CMOS technology allowed the same devices to be fabricated using it, adding the letter "C" to the device numbers (27xx(x) are n-MOS and 27Cxx(x) are CMOS). So what if the thing that we want to store is bigger than complete text of the Ghostbusters theme as written and performed by Ray Parker Jr? As it happens, you can get EEPROM devices with much larger storage. For instance, the Microchip 24LC1025 can store up to 1025 Kbits! That's 128KB, enough space to have some real fun with! Same is true for whatever other microprocessor was used ... if the EPROM stored the configuration for an FPGA you have a whole different problem).For large volumes of parts (thousands of pieces or more), mask-programmed ROMs are the lowest cost devices to produce. However, these require many weeks lead time to make, since the artwork for an IC mask layer must be altered to store data on the ROMs. Initially, it was thought that the EPROM would be too expensive for mass production use and that it would be confined to development only. It was soon found that small-volume production was economical with EPROM parts, particularly when the advantage of rapid upgrades of firmware was considered.

I've also nearly completed a modern windows program to driver the programmer, but a linux command prompt is probably sufficient as the entire protocol is printed on the top of the programmer and is text based. You just need to convert data into an SRecord. There is even someone who has done it for linux https://www.youtube.com/watch?v=HaJ7cCiF-0c although they haven't posted there code yet.

Following the invention of the MOSFET (metal–oxide–semiconductor field-effect transistor) by Mohamed Atalla and Dawon Kahng at Bell Labs, presented in 1960, Frank Wanlass studied MOSFET structures in the early 1960s. In 1963, he noted the movement of charge through oxide onto a gate. While he did not pursue it, this idea would later become the basis for EPROM technology. [3] Update: It f**kked away a ’08 W169 A class’s flash. Toke a lot of time to repair it. My dealer said that it can happen often @ Benzs. Maybe the only way to avoid data loss is to push the “Read ID” button first. If the identification is ok, then you have your chance (tested on a ’11 W245 B class). Other mistake was made by a CAS4 reading of this eprommer. Can’t tell ya more about this just readed about it.

Texas Instruments (1997), TMS27C040 524,288 BY 8-BIT UV ERASABLE TMS27PC040 524,288 BY 8-BIT PROGRAMMABLE READ-ONLY MEMORY So I got out my old beebug kit and predictably, there were issues that weren't there when I last used it! Early "Stored-Program" type computers — such as desk calculators and keyboard interpreters — began using ROM in the form of Diode Matrix ROM. This was memory made up of discrete semiconductor diodes placed on a specially organized PCB. This gave way to Mask ROM with the advent of integrated circuits. Mask ROM was a lot like Diode Matrix ROM only it was implemented on a much smaller scale. This meant, however, that you couldn't just move a couple of diodes around with a soldering iron and reprogram it. Mask ROM had to be programmed by the manufacturer and was thereafter not alterable.

One last thing. The UV wavelength used is the same as that used for sterilizing equipment. It is not the harmless UV found in disco lights. Don't look directly at the bulb when the door is open.
