Reply with QuoteYes, it should run. But probably not very well. TCNC really needs at least a math coprocesser, though. And the attainable pulse rate is pretty much processor dependant, so you may be pretty limited when it comes to speed.
Would TurboCNC run on THIS computer?

My brother still has his first comp. it,s an 8088 ! old and so slow !!!

With that configuration of 20Mhz, how fast would it be with TurboCNC?

Download it and see. Most people use at least 100Mhz PC's, and the speed you get can vary quite a bit, even between seemingly identical PC's.

holy smoke !! did anyone look at the price at the bottom of that link ?
you can easily pick up an old pentium pc at a thrift shop for 10 to 20 dollars , which would be plenty to run most control software
If you plan on using TurboCNC you will need at least a 250 Mhz computer for any acceptable level of routing, especially at 60+ inches per minute.
Otherwise, the CNC will set and wait while the computer calculates all the information needed for the next move, especially if doing arcs, circles, and so forth.
I just upgraded to a 600 Mhz laptop for my CNC, because I hope to do some cutting at 150 IPM.
Hope this helps.
TurboCNC works great, and is a very good DOS based product.
Also in the next release, Dave has promised the use of the "Pentium timer" function. This should allow some very fast rapids as there will be a "significiant" increase in available pulse rate.
As stated above, a math co-processor is required to be able to run TCNC.

I have had TuboCNC working on a 386 with math co-processor. It ran my router mill quite well. Then for $7 I bought a 486-66 and the 386 went back to the basement.
