The following recipe will save you loading time on your Applesoft programs. 1. Load Applesoft 2. Do not “RUN” it. 3. Using the DEL command, delete lines 0,940, inclusiv. 4. Enter this line: 950 POKE 18,255 This will give you a preset version of Option 1, Applesoft graphics mode. 5. “SAVE” this at the beginning of a blank cassette and follow it with saves of programs written in Option 1. For Option 2, do the same except make line 950…
The Apple II paddle I/O Port is immediately available to connect an RS232 type. serial mode printer. Tom Geer, of the Empire Electronics store in Burien is probably the first person in the area to have a TTY up and running. If you ask, Tom would probably be glad to give you some hints on how to proceed. There is a simple machine language program in the revised Apple II manual to enable a printer. Empire has ordered a number…
The Texas Instruments Programmer is a unique calculator which provides immediate conversions from, and 4-function calculations., Base 8 (Octal), Base 10 (Decimal) and Base 16 (Hexidecimal). It will also manipulate bits in Hex and Octal modes, with One’s and Two’s, compliments, logical and, or, not and exclusive or, as well as shift left and right functions. Binary conversions are printed on the face, above the appropriate digits, and the machine performs floating point” negative balance arithmetic in decimal mode. It…
Bob Huelsdonk and Val Golding have been hard at work assembling new programs for the software library. See the complete listing below which includes many new programs. Programs from the A.P.P.L.E. library may be ordered as follows: For copies on cassette, send $1. 00, along with 35¢ in postage, a self addressed letter size envelope and the names of the programs desired, to Val. For listings only, a self addressed, stamped envelope. As soon as Val has a printer up…
Users can dress up their Apple II program with a simple tone subroutine to direct attention to error messages and other items of importance. From BASIC, you simply need a Call -1050 ($FBE6). This will produce a 1·000 cycle tone to be emitted from your computer.
A recent letter from Apple Computer announced the publication of a new manual scheduled for late March, designed to teach Apple BASIC to those with no prior programming experience. We look forward with anticipation to its publication. Editors Note: We need it!
Loosely translated, this means there can be no output without input and effort. In order to make this group a success, we need, member input in the form of both articles for the newsletter, and programs for the library. Have you found a sneaky thing your Apple does that is not in the manual? Let us in on the secret with a brief description or storyfor the newsletter. We also need to build our program library. If you have written…
…is the tentative title for this newsletter. The name was chosen with some thought. That Basic (no pun intended) purpose of A.P.P.L.E. is a self-help service organization. If you need help, Call-A.P.P.L.E.. We will attempt to or assist you in solving you Apple-related problems and answer questions. If you stump us, we will try to obtain the answer from outside the group.
By Bob Huelsdonk and Val Golding A subroutine to find the Basic POKE statements for a machine language program or subroutine. Find the starting address of the routine you wish to Poke and convert that to Decimal. Now, in Basic, enter the following program. (n=starting address) 1000 A=n : B=A+19 1010 FOR 1= A TO B: PRINT I, PEEK(l): NEXT I 1020 X =PEEK (-16384) : POKE -16368, 0 : IF X=127 THEN 1030: GOTO 1020 1030 A=A+20: B=A+19: GOTO…
From Volume 1 Number 2 by Val J. Golding Certain copyrighted programs carry restrictions, in the REMarks lines or elsewhere that they may not be duplicated, reproduced or sold, and for good reason. We would. like to discourage from the.outset, the practice of duplicating. either on tape or by printouts, of any program that has such a restriction. A recent article indicated that the cost per Basic line of debugged software has risen to an all time high of $8….
