Default Re: I found it! A very sorry looking MK14.

Yes, it's been suggested before that the MH devices could actually be programmed using the hardware method and algorithm for the SN (Texas) prefix devices - only trouble is, Texas don't ever seem to have made an SN74S571 so it's not as though you can just choose 'Texas / SN74S571' on your 'western' programmer to programme MH74S571s.

Texas did make a SN74S287, and here is an article about programming those - the author points out what may be a critical difference between the SN and MH devices (roughly 8th paragraph down) so they may not be as directly programmer-compatible as it first seems.
