4. The last ten How about you LETTERS ED To expand a little on Ed Carlson s tidbit in the Sept issue I have found that the CHR 96 blank is a good way to detect when an object is leaving or about to leave the playing field in a graphics game For instance in a pinball game you can put a row of 96s across the bottom of the table To you it looks no different than any blank space but to the ball it is a solid barrier When the ball detects a 96 it has left the game re Ty Another good application is in writing games for the C2 C4 in the 32 character mode By putting columns of 96s at the edges you can detect when your spaceship is about to go into the no man s land or the right hand side of the unused display memory and put it back at the beginning of the row so it wraps around properly It is good to use the 96s instead of some other character because of the varying widths of different CRT displays No matter what the screen display width is the barriers are invisible to the player In answer to a question from Ed in an earlier issue the characters from 211 to 214 are profiles of a WWII prop airplane In a manner similar to the Enterprise characters 211 amp 212 are the right facing plane and 213 amp 214 are the left facing plane Credit for this revelation must go to Steve Jones As soon as he told me about them I went right out and wrote Red Baron a dogfight ga

6. Looking at the computer diagram I noticed a 1 mfd capacitor and a resistor in series with the input from the recorder This high impedence load apparently upset the recorder in the record mode but not in the play mode To solve this problem I soldered an eighteen ohm resistor across the input of the computer at the back edge of the board near the input Capacitor C18 on Sams Photo Facts diagram You must be careful to connect the resistor from the input side of the capacitor to ground 14 The resistor cured my error problems with the CTR 39 and had no detrimental effect on the G E recorder I could have put the resistor in the recorder or in the cable I decided to put it in the computer to enable the computer to work with any recorder Although my trouble was with the Radio Shack machine this same problem could occur with other recorders For the man wanting to connect an I B M Selectric to his computer I designed a board containing a 6522 V I A and decoding for address 0008 which drives an I B M I O Selectric The 6522 has sixteen lines which can be individually pro grammed as inputs or outputs It also contains four control lines two timers and a shift register My program reads the video memory and prints anything on the screen The program is in machine language and takes up less than one K of memory I intend when I get time to make it capable of printing a Program when I type
