Apple II Merlin MON mode

Submitted by VIBR on July 26, 2024 - 5:17am

Hello, 

for my DISK II project, I need to write some ASM code on Apple II to simulate various disk protection mecanism (as per TOME  OF Protection), 

Running  a VIRTUA II emulator on my mac with an Apple //e image and Merlin 2.58, I started entering the BELL demo program:

 

* DEMO

     ORG $300

BELL EQU $FBDD

START JSR BELL

END RTS

 

I can compile with ASM, save the source and the object file, but I am struggling with the MON mode in the editor

I should see the compiled code when I do 

* 300L

Connecting multiple Apple II joysticks?

Submitted by RonsCompVids on July 25, 2024 - 12:30pm

On a device like the Paddle-Adapple, is the "A/B" switch just disconnecting the 5V line so that both joysticks are not active at the same time? 

Does anyone possibly have one to test?Thank you!

Does anyone know of any suppliers for parts kits besides ReActiveMicro? They are out of stock, and will not respond to my inquiry on availability.

Apple III Monochrome Display

Submitted by system1834 on July 20, 2024 - 3:55pm

 

 

 

I want an excellent condition Apple III monitor monochrome display. I bought one on ebay that came with an Apple IIe I bought and the display is too dim and I think it is defective. I remember the display as being rather bright when I was kid. Ebay charges $150+ for these monitors and there is no way to know their conditions from the webpage. Where can I get one for a fair price? How could I fix/troubleshoot the one I have? Does anyone have one they want to sell?

Software Automated Mouth (S.A.M.) not working :(

Submitted by Zonared on July 20, 2024 - 1:14am

Hi everyone, I've finally got my Apple ii clone working after much trouble. I'm now running a ROMX :)

I'm trying to get SAM (S.A.M. Software Automated Mouth) to work but I never hear any audio.

I type RUN S.A.M. and select either DEMO, SPEECHES or SAYIT but no sound.

I connect my logic probe to the CLOCK pin11 of the 74LS273 (Octal D flip-flop) to see if its being triggered and I get nothing.

If I jump to monitor and type "C0C0 0" I hear a click from the speaker and my logic probe fires off with a breif logic low. Note S.A.M. is in slot4

Is it just me or does the Asimov Apple II Archive seem to be down? I've tried yesterday and today to get into it and keep keeping a connection timeout. Does anyone know what's goin on?

Apple IIc+ Disk Drive Noise

Submitted by rathern0tsay on July 19, 2024 - 7:59pm

So after some years, I dragged out the IIc+ I bought awhile ago and brought it in.  I got it working briefly, then all of a sudden the internal disk drive started making a high pitched whining noise and won't read disks.  I have a Unidisk 3.5 drive, so I grabbed it and plugged it in.  It worked once, then started making the same high pitched whining noise and now won't read disks.  I'm assuming the problem is coming from the IIc+ itself, and not the disk drives.  Anyone else ever had this issue or heard of it?  Thanks!

Cannot make a physical copy of a .dsk file

Submitted by tony359 on July 18, 2024 - 6:27pm

Hi all,

 

This is mostly curiosity than anything else. I went to run an old game of my youth - we've talked about it here before, "Avventura nel Castello", an Italian text adventure game. The author, Colombini (Erix here), removed the copy protection some years ago and published the game as freeware. 

Unfortunately, I can run the game from my Floppy Emu but if I copy the disk on a physical media using Locksmith, it gives an error while loading or manages to load a bit and then gives an error on the main menu.
