	At the low end is a super-inexpensive programmer that costs about $40 on ebay. It does not burn anything below a 2732 nor can it program 2532's without an adapter. The maximum programming voltage is 21 volts, and the software is a bit confusing to use. However, it does work and is very convenient as it just plugs into a USB port. The software works on windows 10 as well. The version tested is the TL866CS.		At the low end is a super-inexpensive programmer that costs about $40 on ebay.

			Note that the newest model is the TL866II Plus. It has a maximum programming voltage of 18 volts, so it cannot be used to program many of the EPROMs such as 2532A and 2732A. If purchasing this inexpensive programmer, look for the older TL866A or TL866CS models.

	There are 2 types of EPROM's available, OTP and UV. OTP means "One Time Programmable" and as the name suggests these can only be programmed once as they can not be erased. UV types have a window on top of the chip, this windows is made of quartz glass and below the window is the actual chip. When the chip is exposed to short-wave UV light for a specified amount of time (see device's datasheet) all the data will be erased and the device can be programmed again.

	Without going too much into the details it's good to know that generally you will need 8-bit devices and NOT the 16-bit devices. They can be distinguished by the model number as well as the number of pins. In the list below are common model numbers of 8-bit EPROM's. For EPROM's in DIP packages; 8 bit EPROM's have 24, 28 or 32 pins whilst 16-bit devices have 42-pins. Other packages like surface mounted for instance are available but you will need the DIP versions.

	The part number of an EPROM contains information about the manufacturer, capacity and access time along with some other information like the operating temperature range and package type. When selecting an EPROM it is important to have the right capacity and access time; the access time can be lower than needed but should not be higher.

	You don't have to have an EPROM eraser. But they are helpful if you need to erase some pulls that were not cleaned, programmed the wrong code, or want to recycle some parts. EPROM erasers use a short wavelength UV light to neutralize the charges stored in the EPROM cells. Cheap ones capable of doing a few EPROMS at a time are available for about $20.

			To determine which EPROM will be needed to accommodate a ROM file, use the file size (in Kilobytes or Megabytes) and multiply it by 8. Since bits are a smaller data unit and there are 8 bits in a byte, the number of bits will be larger. For example, if a ROM file is 8 KB (Kilobytes), 8KB x 8 = 64 Kilobits; which means a 2764 EPROM would be needed to accommodate a ROM file of 8 KB in size.
