laptop speed

is a intel 486 75mhz with 40mb of ram and a 500mb hard drive enough to do a lap top edit on my lt1 or i mean to run one of those programs

It should work fine, anything that can run WIN95 is enough to run Tunercat. It won't be the fastest thing in the world, but it'll do the job.

The makers of LT1edit recommend a minumun of a Pi@120. I have used aPi@100 with no problems. I don't think I would try a 486.
