This is not entirely accurate. Because the Micromac website was still being hosted at http://www.micromac.com/products/speedy.html
I tried calling the 949 phone # on the site. A German-sounding man answered the phone, and when I asked if this was Micromac, he said "yes, but technically we are now Macupgradespecialist.com with some Micromac stock left". I asked if he had any Speedy accelerators left, and he said he did not, but he said he thinks he had some SIMMDoubler left for the IIfx. As for other Micromac stock (not for IIfx) he said he has another accelerator that starts with a "D" (forgot the model).
