The CmC ADA 1200 drives an RS-232 printer from the PET IEEE-488 bus. The CmC ADA 1200 allows the PET owner to ootaln hard copy program listings, and to type letters, m^iuscrlpts, mailing labels, tables of date, pictures. Invoices, grrphs, checks, needlepoint patterns, etc., using a standard RS-232 printer. The CmC ATA model I 2 W B comes pssembled and tested, without power supplies, case, or RS-232 connector for 598.50. The CmC ADA 12(WC comes complete for $169.00. Specify baud rate when ordering. (300 baud Is supplied unless otherwise requested. Instructions for changing the baud rate are Included.) WORD PROCESSOR FOR THE COMMODORE PET CONNECTICUT mlcroCOMPUTER now has a word processor program for the COMMODORE PET. This proaram permits composlnq and prlntlno letters, flyers, advertisements, manuscripts, articles, etc., using the COMMODORE PET and an RS-232 printer. Script directives Include line length, left margin, centering, and skip. Edit commands allow the user to Insert lines, delete lines, move lines, change strings, save onto cassette, load from cassette, move up, move down, print and type. The CmC Word Processor Proaram addresses an RS-232 printer through a CmC printer adapter. ZZ — ' ™ The CmC Word Processor Program Is available for S29.50. '■ ____!_ ;„s RS-232 TO CURRENT LOOP/TTL ADAPTER The CmC ATApter model 4m has two circuits. The first converts an RS-232 signal to a 20 ma current loop signal, and the second converts a 20 ma current loop signal to an RS-232 signal. With this device a computer's teletype port can be used to drive an HS-232 terminal, or vice versa, without modification of the port. The CmC ADA 4tw can also be parelelled to drive a teletype or RS-232 printer while still using the computer's reoular terminal. The CmC ADA 400 can easily be modified to become an RS-232 to TTL and TTL to RS-232 APApter. The CmC ADA 400 does not alter the baud rate and uses standard power supplies. The current loop is isolated from the RS-232 signal by optolsolftors. The CmC ADA 4 W is the perfect partner for KIM If vou want to use an RS-232 terminal Instead of a current loop teletype. The CmC ADA 4»IS comes with drilled, plated through solder pads and sells for S24.50. The CmC ADA 400B comes with harrier strips and screw terminals and sells for S29.50.

    Oral History of Robert “Bob” Schreiner Interviewed by: Stephen Diamond Recorded: June 10, 2013 Mountain View, California CHM Reference number: X6873.2014 © 2013 Computer History Museum Oral History of Robert “Bob” Schreiner Stephen Diamond: We're here at the Computer History Museum with Bob Schreiner. It's June 10th, 2013, and we're going to talk about the oral history of Synertek and the 6502. Welcome, Bob. Thanks for being here. Can you introduce yourself to us? Robert “Bob” Schreiner: Okay. My name is Bob Schreiner. I'm an ex-Fairchilder, one of the Fairchildren in the valley, and then involved in running a couple of other small semiconductor companies, and I started a semiconductor company. Diamond: So that would be Synertek. Schreiner: Synertek. Diamond: Tell us about that. Schreiner: Okay. As you know from an earlier session I left Fairchild Semiconductor around 1971. And at the time I left I was running the LSI program at Fairchild, and I was a big believer that the future marketplace for MOS technology would be in the custom area. And since Fairchild let that whole thing fall apart, I decided there's got to be room for a company to start up to do that very thing, work with big producers of hardware and develop custom chips for them so they would have a propriety product that would be difficult to copy. So I wrote a business plan, and I went around to a number of manufacturers. I had a computer guy [General Automation], and I had Bulova Watch Company, and I had a company that made electronic telephones [American Telephones], and who was the fourth guy? Escapes my memory right now, but the pitch basically was, "Your business, which now you manufacture things with discrete components, it's going to change.

So it's June 12, 2014. We're here at the Computer History Museum. I'm Doug Fairbairn and we're talking with Chuck Peddle, who's the creator of a number of very important things in the microprocessor and personal computer and other things we'll be discussing as part of this oral history. So Chuck, we're delighted to have you here. And thank you for coming over and spending the time with us. Chuck Peddle: Yeah I'd like to go on record right now saying what you guys are doing-- the idea about getting all the old men to come over and talk-- is a great idea. I don't know who came up with it, but it really is something that needs to happen. And it's consistent with-- Fairbairn: Well thank you. Peddle: --it's consistent with what you're doing with the museum. But catching these guys while they're still alive-- I suspect you thought probably Jobs brought it home to you.

  • Personal Computers: How Are They Used in the American Household
    Fourth Floor Oklahoma State University Library PERSONAL COMPUTERS: HOW ARE THEY USED IN THE AMERICAN HOUSEHOLD by STANLEY KEITH WALTON Bachelor of Science Murray State University Murray, Kentucky 1978 Submitted to the Graduate Faculty of the Department of Management College of Business Administration Oklaho ma State University in partial fulfillment of the requirements for the Degree of MASTER OF BUSINESS ADMINISTRATION May, 1984 Name: Stanley Keith Walton Date of Degree: May, 1984 Institution: Oklahoma State University Location: Stillwater, Oklahoma Title of Study: PERSONAL COMPUTERS: HOW ARE THEY USED IN THE AM ERICAN HOUSEHOLD Pages in Study: 100 Candidate for Degree of Master of Business Administration Major Field: Business Administration Scope and Method of Study: This study developes a "post purchase usage survey" for households that own personal computers. The survey was designed, conducted, and analyzed over a period of two months. Additionally, an in-depth look was taken at the entire computer revolution, personal computers, and the changing role households are playing in the computer revolution. Findings and Conclusions: Personal computers used in the Ame rican Household have passed the stage of primarily being used by hobbyist or for only playing games. Home users are adapting a wide varie ty of applications to home computers. However, the American consumer, for the most part, is willing to give up leisure time for pr ogramming activities. But, the consumer is willing to purchase woftware which will provide a similar utility. Nevertheless, these findings have enforced this r esearcher's belief that personal computers in t he American home have become the norm.
