My memory is that in 1988 8MB was a luxurious amount of RAM, that machine would cost 2 to 4 thousand dollars. Most people were still using machines with memory measured in kilobytes. Even serious business users were usually limited to 640KB.

It was luxurious, no doubt.

The 68030 Mac IIx started slightly below $8000 with 4 MB RAM and no disk. I can't remember the prices, but I would expect that another 4MB would have cost up to $2k.
