I've always loved collecting brochures on some of the more esoteric products available for Macintosh computers back in the day.
In the early 90's I saw an ad about adding 8 slots to a Compact Macintosh and I wanted to find out more immediately and sent away for the brochure.
The company was called Second Wave, Inc. and they produced several different external chasis boxes that had their own power supply and could provide either SE style PDS or Nubus slots depending on the computer you wanted to connect to. They also offered 4 or 8 slot options and could house SCSI devices.
This is an extract from the brochure:
I suspect there were others like me that would have loved to have added more slots to their Macintosh, especially the compact models.
I've also read with interest on the forum that some newer PDS cards have appeared in recent years that cater for a second card but I always thought this original external box idea was the way to go. It gets round all of the space, power and heat issues you have to contend with and seems to offer a very neat solution since you can easily unplug the unit from the Mac if not required without having to constantly open the machine and unplug cards.
At one point there was even a version available for the Macintosh Plus and Macintosh Portable.
Did anyone ever own one of these Expansion Chasis boxes?
I kept in touch with the company during the 90's and they would send me periodic updates on other boxes available and pricing etc.
At one point I was offered an ex demo SE 4 slot PDS chasis for £295 and I'm kicking myself I didn't buy it but this was 1994 and the SE was a literal dinosaur by this stage with so many new machines and models appearing. I was worried no one would even remember what an SE slot was never mind that I would be able to source any cards for it! Also with Apple starting to produce machines with fewer Nubus slots it didn't feel like Nubus would be around for much long either.
Still I'd love to see a truly MAXed out Macintosh YouTube video with an SE/30 connected to an 8 slot Nubus Second Wave Chasis and all 8 slots occupied with working Nubus cards and 3 half height SCSCI devices also added to the box! Now that's what I call an upgrade!
