- Actually neither is true. The main problem with the r3k indigo was that
- there just wasn't room on the CPU board to put the chips that did the
- memory interleaving/control, so they had to go on the back of the simms.
- It was definitely not a conspiracy on the part of SGI marketing to squeeze
- more money out of customers. The engineers sincerely felt bad to have
- to make that sort of engineering trade-off, and vowed never to do it
- again. They have lived up to it in the new r4k indigo.
