The LP110 was designed a general purpose EPROM programmer. With three different programming-modules it can program 2716, 2732, and (2764/27128/27256) EPROMs. Programming-modules are essentially socket adapters and are not included with the LP110. They are easily constructed from readily available proto-boards. Complete schematics for the LP110 and personality modules are included.
The LP110 communicates with the host system via an RS-232 serial port. A communications program capable of ASCII file transfer is the only software required, so the LP110 will work with almost any computer regardless of operating system or processor type. EPROM programming is controlled via the following menu:
[1] Set EPROM size [P] Program EPROM from RAM [2] Set programming voltage [V] Verify EPROM with RAM [3] Set programming algorithm [C] Compute RAM checksum [4] Set EPROM base address [M] Modify/display RAM [5] Set file transfer format [R] Read EPROM into RAM [E] EPROM erase check [D] Download RAM [U] Upload program to RAM [Q] Quit to opening menu
The LP110 is also an excellent experimenter's board. The LP110 provides a MC6803 8-bit processor, two MC6821 parallel interface adapters which provide 36 digital I/O lines, more than 40k bytes of RAM, 16k bytes of EPROM, a RS232 port, and a digitally programmable voltage regulator.
Each LP110 comes with a developer's package, providing access to the LP110's hardware and software resources. The LP110 source code and a DOS cross-assembler are included. This allows the serious hobbyist to design custom interfaces and write the drivers for them. Custom programs can be burned into the EPROM or uploaded to the LP110 and executed from RAM without modifying the EPROM.
