Advise, please, model motherboard which well works with Mach3 (LPT port), without glitch.

Thanks!

The one I use is the GA-8 SIMLH P4 Titan-DDR Motherboard which works perfectly with Mach and my machines.
This is an old board which was bought second hand on ebay - most new boards do not have the parallel port nowdays (although I do use a PCI parallel port card the onboard port is still handy to have).

Tweakie.

Here are the pc components which were used for my new Mach3 pc. The pulse fequency is solid and no problems
at all.
Here are some basics:
- Asus motherboard - M2N68-AM SE2
- 2 GIG Ram
- AMD  64X2 Dual Core Processor 5200+ 2.7 Ghz
- Asus graphics Card - EN9600GSO
- Rosewill PCI pp card - RC302

Works for me anyway and didn't cost an arm and a leg to have it put together.
You may want to consider a dual PP card.
