Note
The UltraPro is a microprocessor based CW keyboard that was very popular and is still highly sought after. It is built largely on two PC boards and is loaded with features.
It has a professional quality, pre-assembled, full-stroke keyboard with key legends that won’t wear off. There are 10 variable length text storage buffers which can be linked together for added flexibility, a 64 character type-ahead buffer with a 3-color LED monitor, and a 4-digit LED display to indicate operating parameters, all of which are selectable from the keyboard.
Three different 4-level code practice modes will send random length or 5-charactor groups with 3,000 characters sent before the sequence repeats.
The UltraPro also has a built-in sidetone oscillator and speaker, and there is a self-diagnostic function: if a chip fails, the chip number will light up on the display. This function also is used during initial testing.
The HD-8999 uses CMOS memory with battery backup to save the buffered text. Total text buffer capacity is 495 characters. The 8999 also features auto serial numbering from 1 to 9999. About the only complaint heard is that the prosign AA is missing. A real gem.
