I had asked about the 1230s a few weeks ago, and got essentially the same reply from Michael:
Hello.
We will have end of april a limited quantity available for sale.
Please confirm your interest so we can contact you once product is available.
As well, please specify what accelerator you are exactly looking for.
Regards,
Michael
I wonder if GVP's switched to using standard SIMMs/DIMMs for these limited runs, and not rolling their own...
