| 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.
