41. The update is made by exchanging a socketed EPROM chip ( a 32k 27C256 ) on the Assigner board. 42. HCI is the basis of operation for a number of non-volatile memory technologies such as EPROM cells. 43. Early the next morning, the team created the final EPROM chips for the mode and installed them in cabinets. 44. Early models stored programs in EPROM and were limited to a single function with a small real-time executive. 45. It is an efficient replacement for BBSRAM, EPROM or EEPROM . It is faster than EPROM and EEPROM solutions. 46. It is an efficient replacement for BBSRAM, EPROM or EEPROM . It is faster than EPROM and EEPROM solutions. 47. For example, an EPROM from a machine numbered 2569 will not work in another Pegasus with a different ID. 48. In 1981, Epson offered a retrofit EPROM kit called Graftrax to add the capability to many early MX series printers. 49. Like EPROM chips, such microcontrollers came in windowed ( expensive ) versions that were useful for debugging and program development. 50. Development of the EPROM memory cell started with investigation of faulty integrated circuits where the gate connections of transistors had broken.
