Booting to DOS with AppleWin in Apple ][ original mode

Submitted by LoadError on July 13, 2021 - 11:27am

In AppleWin, if I set up the emulator to Apple II original, I can boot to the monitor and then switch to Integer BASIC with CTRL/B+ENTER, but I can't find a reliable way to boot to DOS.

If I set up the virtual disk drive (1) with a DOS boot disk, and reboot the emulator, it still boots to the monitor, as it does if I double click the .do disk image.

The only way I found to boot to Apple II original mode with the DOS available is to switch to another machine (eg. Apple II+), reboot the emulator, then switch back to Apple II original and reboot once again.

Submitted by Radioman on July 11, 2021 - 6:20pm

I am a radio guy with limited computer knowledge and No Apple knowledge.  I don't know if I'm in the right forum but looking for help!

I recently aqiured a Apple II Plus and a Apple IIc and have them working.  With them came a M0401 Monitor. It appears to me that this monitor is not comapatble with the II Plus or the IIc.  I would like to test it but how?

Random number generation on the Apple II with AppleSoft BASIC

Submitted by LoadError on July 10, 2021 - 7:17am

Howdy.

I've studied this article which details a well known limitation with AppleSoft BASIC when it comes to generating a pseudo-random number sequence:

I've done some experiments, and there is one thing I still cannot figure out.

Try to do this: set the AppleWin emulator to Apple II+ mode, paste this program, RUN it and then save the emulator state (f11):

Submitted by fixing2e on July 5, 2021 - 10:00pm

 Hello,

I'm looking for info on how to go about troubleshooting this apple iie motherboard I'm working on that isn't powering up. The power supply works and confirmed in full working order. Motherboard isn't even getting the led lit up when power is on sadly. I was wondering if anyone here would have some pointers as to common problems causing this please? I do have a multimeter and can follow along with most suggestions anyone might have.

Submitted by marian.popeanga on July 2, 2021 - 1:59am

Hi.  

 

Does anyone have a manual for this card or knows where on the apple ii main pcb the 5 hooks on this board should connect ? There are are also 3 jumpers on it.

 I managed to find only the first 2 pins are sync and gr signals and they can be disabled by 2 of the jumpers on the board when available on apple ii plus.

 

Not sure about pin 3 & 5 and the vertical jumper in the middle of the biard. Pin 4 is gnd. 

Any help is appreciated 

 

Thanks

Apple-II beep but strange Video

Submitted by Thomas_R on June 27, 2021 - 9:27am

Hi all

 

Try to get an Apple-II working, get the starting beep but there are only stripes and strange characters on the screen (see picture)

The four voltages are ok, tested also the RAM and 74xxx chips, all are working. Changed also the ROM's with a working system.

Any advise what could be wrong with the board?

Thank you for your help!

CFFA3000 and supported file formats

Submitted by Edward-G on June 26, 2021 - 4:16pm

Although I have been using retro computers for many years, I have only been using Apple II computers for a short time. I recently obtained an Apple IIGS and am having a lot of fun with it. I am using it with the Floppy Emu device by bigmessowires.com to load my software. The Floppy Emu supports a wide variety of file types. I am considering purchasing a CFFA3000 card from ReActiveMicro.com, but would like to get a better handle on what file types it supports. Although the manual for the CFFA3000 does list some file types, I do not believe it mentions all the supported file types.
