Nope he doesn't have to take back any words. All IyonixPCs are complete, and have been from day 1 of retail release.
I used CDBurn on the first evening to back up my disc image, made another copy via the ethernet card and a hub onto a RiscPC hard drive. I have been running my monitor at 1600x1200 16million colours since then without any oddities in the display. I have had access to the full amount of 512Mb of RAM from the first time I started up the machine at home.
A minority of the Iyonix owners have stability problems in the same way that a minority of SARPC owners suffered from the so-called timing problems. That Castle have taken the problem seriously and research a solution that appears to bring great improvements is a sign of their commitment to their customers.
As you are commenting here I assume that all Omega and Mico customers have fully functioning Ethernet cards that support all network apps that run on a RO4 RiscPC?
Oh and seeing as an "optional 2nd processor via daughter board, Intel XScale 80200 up to 1 GHz" is listed in the BASIC Omega specification that all Omega users who wish to pay for one now have fully functioning I GHz XScale 2nd processors running 26bit programs?
