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…

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.

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…

By Mike Thyng In the previous articles, we’ve discussed types of files – sequential and random – and general facts and figures about the PERSCI floppy disk drive. This issue I’d like to explore some of the actual commands necessary to get data to and from the diskettes. Before you can write a file, you have to do something called “opening” it.  This defines to your program that some related data – let’s say names and addresses – is going…

By J.A. BACKMAN If you have dumped a program by hitting “RESET” when you meant to hit “RETURN” and Ctrl-C wouldn’t bring the program back – – I’ll bet the air was as blue around your APPLE II as it was around mine! – ! – ! A sweet little fix is a simple gadget that stops accidental keying “RESET” but does not stop its operation when it is needed. It does not hide the key, and doesn’t require lifting…

By Bob Huelsdonk Some protocol is a must if you use a printer with greater than 40 columns with your Apple.  This comes about because it tries to write beyond the screen area and into the variables area in Integer BASIC or into the operating system in Applesoft.  The following fix will help prevent this problem: Start your printer driver routine with a JSR FC58.  This will home the cursor and clear the screen.  Do not return to the screen…

June 1978 To all A.P.P.L.E. Members: please note that our library now has a LCOS (Limited Cassette Operating System) for all of our cassette based programs.

The Apple ][ is country’s best seller?  This is what Phil Roybal, Apple Computer’s marketing manager expressed to us when we asked him recently.  Apple’s new Shuggart mini-floppy has now been officially announced at an unbelievably low $495.  The Delievery is scheduled to commence in lat June.  This drop of $200 was enough to influence our decision to buy. The Applesoft II ROM board will be available at $100 for an introductory period only, running through July 31st, at which…

COMPUTER COMPONENTS – formerly known as COMPUTER PLAYGROUND offers some large storage for Apple users in the form of PERSCI floppy drives.  This is the first in a series of articles about the “large” floppies available for the Apple ][ The drive is the PerSci Model 277 dual diskette drive.  this means it has two eight inch floppy disk surfaces with approximately 256,000 bytes for storage.  Half a million bytes of disc storage per drive!  optionally selectable is the dual…

by Dana Redington = Apple Computer, Inc. More word on the utility Rom. In addition to the routines previously mentioned, this Rom will have new high-res operating routines, including a SHAPGEN command that will eliminate the need to manually write HIRES vectors. You will be able to directly address a d0t matrix, and there will also be a HIRES Ascii character set, displayable concurrently with the graphics. The Applesoft Rom board is scheduled for release to dealers July I st…

21 March 1978Time: 1905Place: Burien Empire Electronics The meeting was held at Empire Electronics in Burien.

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…
