User`s manual
This user's manual covers some B+K Precision programmers: 
865, 866, 864, 844USB, 844A, 848, 848A and 849. 
865 is a universal programmer and logic IC tester with 48 
powerful pindrivers in base configuration, expandable up to 
256. This design allows to easily adding new devices to the 
device list. 865 provides very competitive price but excellent 
hardware design for reliable programming. Best "value for 
money" in this class. 
866 is a fast universal USB/LPT interfaced universal 
programmer and logic IC tester with 48 powerful pindrivers. 
Using build-in in-circuit serial programming (ISP) connector the 
programmer is able to program ISP capable chips in-circuit. 
This design allows easily add new devices to the device list. 
866 is a true universal and a true low cost programmer, 
providing one of the best "value for money" in today's market. 
864 is a universal programmer and logic IC tester with 48 
powerful pindrivers. This design allows to easily adding new 
devices to the device list. 864 is a true universal and a true low 
cost programmer, providing one of the best "value for money" 
in today's market. 
844USB  is a small, fast and powerful USB interfaced 
programmer of all kinds of programmable devices. Using build-
in in-circuit serial programming (ISP) connector the 
programmer is able to program ISP capable chips in-circuit. It 
has design, which allows easily add new devices to the device 
list. Nice "value for money" in this class. 
844A is a small, fast and powerful programmer of all kinds of 
programmable devices. Using build-in in-circuit serial 
programming (ISP) connector the programmer is able to 
program ISP capable chips in-circuit. It has design, which 
allows to easily adding new devices to the device list. Nice 
"value for money" in this class. 
848 is a small and powerful EPROM, EEPROM, Flash EPROM 
and serial EEPROM programmer and static RAM tester, 
designed for professional mobile applications. In addition, 848 
programmer with auxiliary modules support also 
microprocessors (MCS48, MCS51, PIC, AVR), GALs, etc. 
Programmer can work with 'true LV' device too - from 2V. 
848A is a little and powerful programmer for EPROM, 
EEPROM, Flash EPROM, NVRAM, serial EEPROM and static 
RAM tester. 
849 is little, powerful and very fast portable programmer for 
MCS51 series and Atmel AVR Microcontrollers with ISP
