Re: [N8VEM-S100:3116] Re: GAL's and PALASM

An update.
  I'm now getting predictable results for my 22V10 GALs.
  My first issue was with my proto-board; VSS was set to 4.6V, I adjusted it back to 5.0V, this immediately corrected some on the issues I was seeing.

I have 22V10s from 2 different manufactures.

  I have several of these that were pulls from equipment being scraped.
  PALASM device set to:
            CHIP ABC_GAL PALCE22V10  ; Use with AMD PALCE22V10H-25PC
  VP-390 device set to:
            AMD PALCE22V10H-25PC/4

  I bought these from Jameco.
  PALASM device set to:
            CHIP ABC_GAL PAL22V10    ; Use with LATTICE GAL22V10
  VP-390 device set to:
            LATTICE GAL22V10

My test files all compile for both 'CHIP' definitions; the VP-390 programs the devices correctly when it's set to the same device PALASM compiled for.

In all my test cases taking care to configure both PALASM and the VP-390 the same I'm getting solid repeatable results that are functioning as expected on my breadboard.
