That's not necessarily true either. A scheduling analysis could be performed to determine the real-time capabilities of the system. A simple stability program running on a massively overpowered linux system could be proven to guarantee scheduling at a low update rate. It's just not an efficient real-time system.

The Sotheby's notes about the Apple 1 say it is one of six thought to be operational boxes and one of about 50 known to exist."

For Natural Gas (@0degC)
Specific Heating = 47.7MJ/kg
gas density = 0.72 kg/m^3
cost ~= 0.25 $/m^3 (typical Ontario with distribution)
efficiency = 50%

= 4.77 kWh/m^3
= $0.052 / kWh

this would assume it could run on natural gas, but it needs pure methane. Even so, it ends up cheaper than grid electricity.

I've used a GQ-4X Willem Programmer with good success. The trick is to get a good set of adapters, so you have the flexibility to cover many packages. PSOP, TSOP, etc. I've even found one that lets me do a serial SOIP8 EEPROM while it is still on the board-- very handy to not need the remove&resolder.
