[DSP-10] HEY !! Bob !! Re: Corrupted Monitor on DSPx

[Bob Larkin]

Hi Rich,

I had a chat with KD7TS and W7CQ this AM, relative to flash chips.  I 
hunted about and I have several that are programmed with v2.95 of the 
monitor.  Send me your mailing address (off the reflector, if you want) 
and I will send you a new monitor.

73, Bob  W7PUA

I have been looking into obtaining one which will work with these types of flash devices, as I need to store the CAL parameters of at Tektronix 2440, which are stored on Dallas NVRAM (also 70ns devices).
