Note: Although GVP-m's website lists phone, fax, and e-mail contacts, as of this writing (July 2018) no-one is handling any enquiries. On November 23, 1999 Simon Goodwin managed to get a reply back from a "Michael" at GVP-m:

Are your A4060 boards still available? I ask because
the Phase 5 ones are not, and they're not as good as
yours anyway--but since Power stopped advertising
yours, they've been unadvertised here in the UK. :-(

Also I regularly get asked if the custom GVP SIMMs
are still available. Please advise.

Best wishes,

Hello Simon

Thank you very much for your e-mail.

The A4060 boards are available as well as all sizes of GVP simms.

Let me know what you are interested in exactly and how many, so
that I can let you know about price and delivery details.

So Long,
