31. Windowed and windowless packages were also used for microcontrollers, and other devices, containing EPROM memory. 32. The PIC, however, was upgraded with an internal EPROM to produce a programmable channel controller. 33. A switch on the Bytesaver card was used to turn on or off the EPROM programming voltage. 34. Complaints from operators losing revenue due to lurking led to the creation of an EPROM restricting such chances. 35. Firmware is held in non-volatile memory devices such as ROM, EPROM , or flash memory. 36. EPROMs can't be erased electrically and are programmed via hot carrier injection onto the floating gate.37. Fitting all this functionality in 4 KB of 2732 EPROM required a lot of effort and some sacrifices. 38. RAM and EPROM were separate, often requiring memory management or refresh circuitry for dynamic memory as well. 39. The casino operator can choose which EPROM chip to install in any particular machine to select the payout desired. 40. This board also has the SCSI controller and an NEC V20 processor, and additionally a 32k EPROM chip.
