Need help adjusting disk ii down pressure

Submitted by mochatea396 on July 28, 2024 - 9:42pm

Hello group,

I have a disk ii that has poor down pressure when the door is closed. The drive performs fine (how I don’t know) but there’s clearly no where’s near the pressure you feel when I close all my others. I checked that all the washers are in the hub, and both springs are present. Anyone know how to improve this closing pressure? A better way to describe it is it feels like the hub isn’t giving the down pressure on the disk when the door is closed.

S-C Assembler v2.0 for DOS 3.3 crashes to monitor on startup

Submitted by sbaker51 on July 28, 2024 - 2:36pm

Does anyone know how to fix the this version of the S-C Assembler (v2.0 for DOS 3.3) such that it boots normally with the AppleWin emulator?

The following occurs:

Orig Apple II               - it crashes to address 9D89

Apple II+                     - it crashes to address 9D89

Apple IIe                      - it crashes to address 9D89

Apple IIe(enhanced) - it crashes to address 9D88

NB Apple DOS versions 1.0 and 1.1 boot normally as does the ProDOS version 2.0

New UK Appler - need help with a PAL/UK IIe

Submitted by LoccyDaBorg on July 26, 2024 - 6:19am

Hi all,

I run vintage computer exhibitions out of a UK university - we do big ones that are open to the public and also smaller, pop-up ones during our open days and in outreach events at local schools. Most of the machines I showcase are from my own personal collection, so as such are heavily biased towards UK legends of the 80s - Sinclair Spectrums, BBC Micros etc. But there's also plenty from your side of the pond too, Commodores, Ataris etc. I recently acquired my first Apple for the collection, a UK PAL IIe in absolutely glorious condition.

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?
