I noticed the 512KB version of this on Ebay, great work it's very interesting to see the progress hopefully the full blown version will become available for sale.
One thing I wondered is that is there any reason to have more than 512KB of slow memory? I understand that some old software needs it for compatibility reasons but would you not be best of with as little slow memory as possible and install real fast memory instead? or is there software that specifically needs more than 512KB of slow memory?
