215:$ 250 cost would probably be more useful as part of the purchase price of a second disk drive, but those with two drives "would find the high speed and special capabilities of a Happy drive to be a worthwhile investment" and "a pleasure to use". Moriarty concluded, "I hope the ATARI community will not abuse this power by using the Happy drive (and other similar products) to infringe on the rights of others".
230:. The 1050 Enhancement was a plug-in board and could be installed without soldering or permanent modification. In addition to the buffered reading and writing with zero latency and faster serial I/O, it supported true double density (180 KB). The serial I/O of the 1050 Happy was faster than the 810 Happy due to the faster speed of the

time decreased to 25 seconds from 38, and drives would last longer because of more efficient disk access.
