Execute binary file on boot-up

Submitted by gobblebit on July 17, 2019 - 8:31am

I have a binary file (asm program) that I've been using AppleCommander to place onto a DSK image, which I can then load into AppleWin. The program runs as I'd expect it to, but to use it I need to "BRUN <program>" from the initial Applesoft prompt. I know that the HELLO program on the disk is executed on boot, and that INIT can place the current BASIC program as the HELLO program and thereby run that program on boot. However, I'd like to run my binary file at boot up as if it were HELLO.

Testing Ram on apple II Plus.

Submitted by NovellNetware on July 17, 2019 - 1:17am

I used the following program.

 

C050 C053 C054 C057 N 265:FF N 266<265.BFFEM 266<265.BFFEV 265:0 N 266<265.BFFEM 266<265.BFFEV 34:14 (Return)

 

came back with serval numbers.  All the original apple chips have some stuff on them. But not down into the pin socketts. Of all strange things. I would just like to replace the 48k total with all new memory due to this. If somebody can point me in the correct direction. I would appriciated it.  The numbers on the chips are tm-s4116-20nl. So Texas instruments 20n ns? chips.

RAM2E - 2MB RAMWorks-compatible expansion for Apple IIe

Submitted by Zane Kaminski on July 15, 2019 - 6:38pm

As mentioned in my "five new open-source Apple II cards" thread, my friend and I have developed some new Apple II card hardware, so the first one I figured I'd try to finish is the RAM2E (GW4203) for Apple IIe. This card goes in the auxillary slot and adds 2 megabytes of bank-switched RAM, switchable by writing the RAM bank address into the softswitch at C073.

Five new opensource AppleII cards coming soon, but we need your help

Submitted by Zane Kaminski on July 14, 2019 - 1:04am

We (at Garrett’s Workshop) were a little surprised at how many people were interested in our GW4201-series RAM expansion for IIgs, so we figured we would design some new cards for the rest of the Apple II family:

Disk ][ LED fun

Submitted by macnoyd on July 13, 2019 - 9:10pm

I took a little time today to get my hardware fix and decided to draw up a schematic to the bi-color LED circuit published so long ago buy Fabien Bénattou.

Disclaimer by me:  I did not design this.  I only drew it to show it's simplicity.  Very clever design that most with a little electtronics experience can build.

With a little more circuitry, you can see how this can be an insert directly to the Disk ]['s ribbon cable rather than something wired onto the analog board.

Submitted by Khaibitgfx on July 11, 2019 - 6:16pm

If anyone needs a new updated copy of the Apple II Redbook you can email me for the PDF, it has many improvements over the 2008 PDF which I also made.

This version contains many new pages that were not done in 2008.

In the months to come the entire Redbook is being redone with all pages complete.

Coming soon will be the Apple II Bluebook.

Trying to find Avalon Hill Tournament Golf disk image

Submitted by old_hitech on July 7, 2019 - 2:30pm

I am on a golf game binge and have an original disk for the Apple II Avalon Hill Tournament Golf game. I bought this game back in 1980s and remember having fun playing it. But now the game disk will not boot and I cannot play this game. I've looked for a disk image at many Apple II disk repositories and cannot find this one. Anyone out there have a disk image of Avalon Hill Tournament Golf for the Apple II? Thanks!

New Owner of a Apple IIe

Submitted by mbc230 on July 4, 2019 - 12:25am

Hello All....Great forum and glad to be a new member. I am a proud of owner of a recently purchased Apple IIe that I bought off of ebay (Price was right). Well I unboxed the computer. It came with a color monitor (with a broken RCA male end stuck in it. Had to take monitor apart to remove it), CPU was full of rat poop (Seller claimed the computer was in a storage unit (Had to take apart to clean it all out), and came with the dual set top DuoDisk disk drives. So the issue I am seeing is no matter what disk I put into the drives the red light stays on and the video is displaying Apple IIe.
