I made one of my infamous "high-tech-tie-tacks" out of one of these white ceramic-with-gold-leads 1702's. It's quite an atractive piece of jewelry. These parts are still routinely available, though not every day, for a couple of bucks at local surplus outlets, so I'v enot been concerned about their scarcity. Nope, your Needham burner probably can't deal with the 1702. It was a difficult part to program, unlike what the Needham type burners (5-volt-supply-only, IIRC) normally handle. The 1702 required a -9-volt supply, IIRC, and not just the -5-volt supply that the later multi-voltage parts required. The 1702, IIRC required a significant negative voltage, (-49 volts or so) for programming and few programmers, other than the Data I/O Model 29 that I occasionally used at work, would do that. Consequently, they'd probably not have suppported the I'm not even sure the Needham programmer will do the 2708 and 3-voltage 2716's. Will they? National made an MM5203 that was also 256-bytes in size and was also difficult to program. It was an even more suitable part for jewelry, as it had a gold flash all over its upper surface. It was quite a striking piece of hardware with its large gold surface and extra thick quartz window glued to the top.
