Mountain Computer Music System hardware fix

Submitted by amauget on October 12, 2019 - 6:16am

Hi all,I'm trying to use a Music System into an Apple II+.I got the message "** ERROR ** MUSIC BOARD NOT IN MACHINE  PRESS SPACE BAR WHEN READY" when trying to use the card with the software.I have tried different disks images, different motherboards, different slots. I even bought another Music System. No luck.Then I look into the manual, always RTFM :-)At the beginning, there is a notice stating that if you encounter my problem (and others) you have to install a little board with 100 pF capacitor at location B11, where a 74LS08 is. I'm trying to figure out how can I reproduce this board.

Trouble with ADTPro ESDos while bootstrapping an Apple //e over audio

Submitted by chubzthecoder on October 10, 2019 - 5:54pm

Hi all! My first post here!

I've been having a problem with my Apple //e when trying to make a DOS floppy disk using ADTPro from bare metal using the audio cable, everything works fine in ProDOS when I send it, but when I go to format the disks, it just says I/O Error, but the drives at least spin up (this will be relevant later). I even tried both of my 3.5 in. drives to no avail. So then I tried to use ESDos, because it turns out, that's what ADTPro recommended for my situation.

ADTPro and backing up a full Profile HDD from Apple /// to OSX

Submitted by abeckett on October 10, 2019 - 5:03am

Hi there -

 

First time poster, brand new member. Im trying to backup an Apple /// Hard Drive to my Mac using ADTPro. It works, apparently, however the image.po file cannot be seen. OSX shows the folder is 5 MB in size but ZERO items inside.

 

As a result, I am feeling dimwitted and have no idea what I have possibly done wrong. I set the working directory, named a file... I have also done nothing and checked what happened.

 

Anyone done a full image and had weird behaiour like this?

 

Thanks;

Finally got an Apple II+. What's next?

Submitted by cbmeeks on October 8, 2019 - 4:39pm

I have several IIe's, a couple IIgs's and a couple IIc's.  But I always wanted an original II and II+.  I can't afford a II and, over the years, I've noticed that II+'s run around the $200 - $400 range depending on condition, etc.  However, I've noticed recently a few under the $200 range.

Any FAQ/info on file transfers, disk images etc?

Submitted by Fuji on October 8, 2019 - 5:07am

I'm in the midst of reviving my old Apple ][+ clone, and while waiting for some replacement components to get the computer going I thought I'd look into the software side of things and try to refresh my knowledge of how to use my (5.25") floppies and transfer files and programs to/from other platforms (most notably a current Mac, or an Atari STe in case a serial port is needed which my Mac doesn't have).

I'm sure these things get asked all the time, so I'm wondering if there's a FAQ, an online guide or something which I can read to catch up?

Power Supplies - rebuild or replace outright

Submitted by william_tell on October 7, 2019 - 1:17pm

I've been searching this forum, and there is lots written regarding Apple power supplies... I'm stll digesting it all.

Without trying to stir the pot...    I have several Apple ][+, //e and even 2 //c's....    And from what I have read I believe I shouldn't operate any of them with their original PSU's.

I feel I have the minimum skills to replace capacitors..

Apple Disk II speed control board failure

Submitted by gjbl on October 6, 2019 - 12:38pm

Now, here is something for real Apple2 experts  :-)Apple Disk II - the diskette spin motor won't start, all other functions seem to be OK, but with floppy not spinning its hard to tell. The analog board looks OK, the "motor on" signal is generated, the motor itself spins when powered. I traced the problem to the speed control board (SCB), initially I suspected Q4 (the power transistor), but it looks OK, BUT ... Q3 is faulty!  There is no visible damage on the board, no signs of overheating, etc. It is rather rare that a low power transistor fails by itself...
