![]() When it rang, the computer would answer the phone and establish two-way communication via the modem. ![]() Although not run on an Apple II, the event is significant because it was the start of a phenomenon that expanded to include nearly all models of personal computers, and ran strong for over fifteen years, finally waning in popularity because of the rise of the Internet.Ī typical BBS consisted of a single computer that was always turned on, waiting to answer the phone. With time it evolved into a more sophisticated system, allowing exchange of files and other features. The CBBS began in February 1978, and at first was no more than a computerized version of the club’s paper-and-thumbtack message board. It was designed by Ward Christensen and Randy Suess of the Chicago Area Computer Hobbyist Exchange (CACHE), an early microcomputer user group. The first recorded use of a home computer for the purpose of hosting such a message system was the Computer Bulletin Board System (CBBS) in Chicago, which ran on a Vector 1 computer (an Altair clone). These message systems, which became known as “bulletin board systems” (BBSes), were started almost as soon as the first generation of home computers became popular. Although some needed to use their Apple II simply as a home terminal to access a school or business mainframe or timesharing system from home, many users created their own self-contained dial-up message systems. Although some inexpensive imaginative methods have been employed (such as A.P.P.L.E.’s “ Apple Box” that used the cassette port to send and receive programs via the phone line), the release of the DC Hayes Micromodem II for the Apple II in 1979 and the Novation CAT in 1980 made it possible for a new type of computing. “I can actually mold right off of the finish with the HAIMER tooling.Since the earliest days that it was available, there have been Apple II users who have found ways to connect to other Apple II computers over the phone. “With the HAIMER tool holders, I can in certain situations not polish the mold if it lends itself,” Randy describes. Uniform pressure on the cutting edges in the HAIMER shrink fit tool holders leads to, among other things, better dimensional accuracy, surface finish, smoothness and tool life and Omega Tool, Inc. ![]() 0001”, tools cut naturally, allowing for more aggressive HEM, higher SFM, consistent tool wear, with superior surface finish.” “With coolant through drilling applications, this means near complete confidence that runout is eliminated when using a HAIMER heat shrink.n Milling is even better, since runout is under. “The main reason we use heat shrink is it significantly reduces runout and increased rigidity,” another 5-Axis Programmer at Omega Tool, Inc. HAIMER shrink fit tool holders make processes throughout production significantly easier in regards to tool runout, reach and clamping force. The Solution: Part Two - The HAIMER Shrink Fit Tool Holders “We consider the HAIMER Power Clamp Special Edition such a workhorse because it has never broken.” “The cooling time, the heating time…it is all so consistent,” states Randy. HAIMER guarantees < 3μm run-out at 3xD and this degree of accuracy is consistently repeatable for any number of operators from shift to shift. received repeatable uniformity in tooling setup and equally consistent results. Regardless of the operator and their experience level, Omega Tool, Inc. started to notice how consistent the machine can set up tools, which is a unique benefit of the HAIMER shrink fit system. team decided to purchase two HAIMER Power Clamp Special Edition shrink fit machines.Īfter using the HAIMER Power Clamp Special Edition for a while, Omega Tool, Inc. “The reason for switching was simple…quality! There isn’t a tool holder on the market that has the consistent repeatability of a HAIMER tool holder.” “I have known of HAIMER tooling for quite some time,” Randy describes. decided it was time to invest in another tool holder and shrink fit system, they didn’t have to look far.
