Month: August 1978

Here is a quickie about setting up the APPLESOFT ROM card.  First, as the instructions indicated, this card will function only in Slot #0 of your Apple ][.  This card allows you to make a choice of whether you want Integer BASIC or APPLESOFT to be called with Control-B after you power up.  If the switch is in the down position, APPLESOFT will be selected.  In addition, it is not necessary to change the switch position to call the non-default…

As we were going to press, we were handed a copy of the NEW documentation on Disk II.  We are pleased to report that this documentation, running nearly twice the length of the original.  It is far more concise and detailed and has a very good introductory section.  So all you gentle folk at Apple Computer, we retract (sort of) some of the nasty things we said in this month’s editorial (http://www.callapple.org/1978/08/01/an-a-p-p-l-e-editorial-2/). However, we still feel that the Disk II…

Dear Call-A.P.P.L.E. I am writing to say I am very impressed with the Call-A.P.P.L.E. newsletter.  It is not only informative, it is also very useful, particularly the section dealing with the System Monitor and Mini-Assembler, since I am especially Interested in Assembly Language.  How about making an Assembly Language Tutorial tape.  Also, how would I go about getting a copy of the listing for Integer BASIC?

Dear Mr. Golding I recieved my July issue of Call-A.P.P.L.E. after joining the group.  I think you are doing a great job on Call-A.P.P.L.E.!  In Stopwatch (Library Pak 1A), the display flickers, this can be fixed by changing line 190: Change POKE 34,22 to POKE 34,24. I also have a question that others might be interested in too: How do you use HI-RES with Integer Basic >LOAD without asking the operator to manually enter >HIMEM: 8192?  By listing your program,…

To: Call-A.P.P.L.E. I purchased a set of 16K dynamic RAM from “Advanced Computer Products.”  They passed the memory test in a previous issue of this newsletter.  The price was eight chips for $200, with a six week delay waiting for their “same day shipment.”  Remember to have a set of three 14 pin sockets on hand for your memory select jumpers.  Thanks for telling how the HI-RES system handles the colors.  I wondered why my blue and green spaceships were…

Perhaps this may be the first disk program published for Apple’s new Disk II. If so, a feather for our cap! The “SAVE” program, listed in column two will ask the user to input the file names of six disk programs, start recording on tape and hit return. SAVE will then consecutively load from disk and save to tape, in one operation, the six named programs. A neat way to make a tape for a friend from your disk collection….

The big news story of this issue is obviously the arrival in town of Disk II and Applesoft II ROM. Rather than do a review, we have hidden behind the pretext of an editorial to state our feelings on the failings of Disk II and A/S ROM.  I’ve got a feeling I’m failing? (Oh dear! )) Applesoft II ROM for $100 is like buying 10K of memory for less than half price, since it frees that amount of RAM for…

Note: In line 400 after the first quote, hit the Control key and the “D” key at the same time. This is how the disk system responds to commands within a Basic program, with Control D in a print statement.

by John Covington Finally! !! Disk II is out. If you’re lucky, you will be able to play with one in your local computer store until yours arrives from Cupertino. That is what I have been doing this last week, and this article comes from using the disk and my varied background in Data Processing. Hopefully, I’ll be able to explain some of the HOWS and WHYS of the disk system and clear up some of the blind spots in…

And now a word from our sponsor …, you! Look elsewhere in this issue for an as yet untitled letters to the editor feature. We are now actively soliciting your letters and will reproduce in part some of the interesting ones. H you have a question or a problem, and we can’t find the answer in time to print it, we’ll throw it open to our readers for solution. Money talks. Unfortunately, we have a number of words on that…

Sorry to do this, but we underestimated both cost and demand on this mini-modem. For those that are unaware, Apple Box acts as an interface between your cassette and your telephone. After connecting it to an FCC type-approved telephone coupler, it allows you to transmit or receive programs over telephone lines. This requires the ability to monitor your line, and if your recorder is not so already equipped, Apple Box II at $23.50 will do it for you.

Apparently, quite a few. You can look forward in the near future to receiving a questionaire in connection with your medical and other applications for Apple II. It would seem that about 10% of our current membership is in the profession, and our objective is to put this large minority in contact with one another. You will also be receiving names and addresses. This also will apply to any other special interest group; we will attempt to put you in…

By Bob Huelsdonk When inputting to a double loop by row, then jumping out to a double loop to total by column, it is necessary to revers the subscript order. This will not work in Applesoft BASIC because the right counters do not reset.  The following simple example will demonstrate: 80 PRINT  “INPUT ‘-1’ TO TERMINATE INPUTS” 100 FOR R = 1 TO 3 120 FOR C = 1 TO 3 140 INPUT A(R,C) 160 IF A(R,C) = – 1…

By Bob Huelsdonk Only line 30001 is required for less than 32K of Memory.  The first GOTO 30000 shows result with  greater than 32K of Memory. The second GOTO 30000 shows the result with less than 32K of memory. 30000 IF PEEK (203)>128 THEN 30002 30001 PRINT PEEK (202)+ PEEK (203)*256- PEEK (204)- PEEK (205 )*256;” BYTES FREE”: END 30002 PRINT 32767-( PEEK (204)+ PEEK (205)*256);” BYTES + “; PEEK (202)+( PEEK< (203)-128)*256 +1;” BYTES FREE”: END >GOTO 30000 30719…

Much of this issue of Call-A.P.P.L.E. was done 0n our own Apple II Computer, nobly assisted by an Integral Data IP-225 printer, along with our own modification of Phil Roybal’s Lower Case Character Generating Program (See Contact, May, 1978) The IP-225 has performed beautifully,  and because you can software-select eight different type fonts, It is ideal for this task.  We believe the smallest available type face, which we are using here, is easily readable, and it contributes further by making…

Sorry to say, many of the “corrected” versions of LPak lA still have a bad copy of Program 8. If you are ordering Library Pak 2 and ask us with your order, we will add program 8 from Library Pak la to your tape. The main reason for this was simply our lack of time to check the tapes. Forgive?
