I've developed two new Mo'Slo products with RSS in mind. Not enough feedback
yet to make specific recommendations, but Mo'Slo Deluxe, with cache
disabling, reportedly runs much of the DOS-based Motorola RSS on some
systems.

The Mo'Slo basic v.1.5 eval has two slowdown methods and a 0.01% slowdown
increment.

Mo'Slo Deluxe v.3.1 has three slowdown methods, 0.01% slowdown increment,
cache disabling, much-improved keyboard control, etc.

The new slowdown methods can reduce heat and power consumption in real mode
DOS (which is what they were developed for, though method 2 does slow more
than a few DOS programs in Windows).
