Like many early S100 board projects of the time, the Dazzler was originally announced as a self-built kit in Popular Electronics. Sales were so fruitful that Melen and Garland formed the company Cromemco to sell the Dazzler and their other Altair add-ons, selecting a name based on Crothers Memorial Hall, their residence while attending Stanford.
Cromemco quickly branched out into their own line of Z80-based S-100 compatible computers. Over time these became the company's primary products.
Cromemco also sold a package of simple games/graphics for the Dazzler boards. These were supplied on paper tape! or cassette tape or 8" floppy disks (later).The Cromemco SDI Video Board

The address bus is cycled around
the desired addresses by the Dazzler, but no S-100 control lines are
adjusted in the process.
I have checked a number of other (Cromemco) static RAM cards that work and they use address latches as well. The difference appears to be that the S-100 clock is also used as part of the logic driving the address latch strobe input (i.e. I suspect the address latches are strobed based upon the clock signal even if a static memory read cycle is 'jammed' onto the S-100 bus).
