Floppy Emu or CFFA3000?

Submitted by clamm on January 10, 2022 - 7:18pm

Hiya folks,

 

I am trying to decide between purchasing a CFFA3000 or a Floppy Emu. My configuration is a stock IIGS with a 3.5" Unidisk and 5.25" drive. Ideally, I'd like the computer to attempt to boot from the 3.5" Unidisk and then the 5.25" and then the Floppy Emu/CFFA3000 and retain the ability to read/write to either drive as necessary.

 

Is this even possible? I am rather confused by all the limitations on the daisy chaining and I don't want to make a mistake and purchase all the wrong stuff.

Are 2HD diskettes completely out of the question?

Submitted by fegos on January 10, 2022 - 4:04pm

Hi, i recently got back with my 80s apple iie.    It has a duodisk drive that i cleaned and speed calibrated and it works with most disks.   I also had an empty NOS box of 2HD diskettes.   I notice that they dont format.     I read in here that HD disks are unreliable.    Should they not work at all? as that is the case on my duodisk.  Or is there something else calibration wise that should be done to the duo disk?  I wanted to know if this HD issue is as binary as i see it on my unit. thanks

Apple ii plus keyboard - letter A stopped working

Submitted by warby on January 8, 2022 - 9:26pm

My dad recently gave me the original Apple ii plus that he bought and I learned to program on. It wouldn't boot and after some troubleshooting, I found the highest range of RAM had a bad chip. I replaced the entire bank of 8 chips (as I saw was recommended on one of these forums) and it worked!  I bought some new 5.25" floppies and was able to create some new disks using the Apple Disk Server (awesome resource!) The power suplly is working but I proactively ordered a capacitor replacement kit.

Duodisk and Unidisk Drives Red Light Constantly Stays On

Submitted by mbc230 on January 8, 2022 - 3:24pm

Hello,

I am new to this forum and I have had issues with two disk drives that I have. They are doing the same thing. The first one is duodisk drive and the second one is a unidisk drive. No matter what Floppy I put in either drive the Red Light just stays on and the disk drives just spin. These are things I have tried. See below:

1. Tried different typed of disks (Originals and Copies - No Change For Both Drives)

2. Tried Two different controllers (No Change For Both Drives)

3. Tried a known working controller on a working machine (No Change For Both Drives)

Apple IIGS & GS/OS 6.0.1

Submitted by clamm on January 7, 2022 - 5:28pm

Hiya Fritters,

 

I've got an AppleIIGS ROM 01 with 512K of total RAM via an original Apple RAM board (with 256K on it).

 

When I put the disk for the GS/OS 6.0.1 it attempts to load and then makes a "beep" sound about midway through the progress bar and then stops reading the drive and stays stuck at the fully-loaded bar. No icons appear at the lower left corner.

 

Is that "beep" sound telling me that I don't have enough RAM to run GS/OS?

 

Thanks everyone for your insights!

Memory issue with Apple 2E?

Submitted by Roger the Brit on January 6, 2022 - 4:15pm

I was recently given an Apple 2e and an Apple 2GS, together with their monitors and 2 5.25 floppy drives for the 2e. I also have what I believe is the original software and manuals that came with the 2e. Using the manuals I got the 2e started and ran the self test. It immediately returned the word RAM and stopped running. After trying the test again I got the same error. I then put in the DOS 3.3 disk 1 and restarted, the drive appeared to go through the motions, but after several minutes there was still nothing on the screen so I did Command, Reset to stop the disk.

Easiest way to program Apple in 6502 from Windows?

Submitted by Kingpin on January 5, 2022 - 10:57am

You guys who program your Apple, how do you go about writing sourcecode in Windows for the Apple (in 6502 assembler that is)?

 

What is kind of "best practise" to lift sourcecode from Windows into say Merlin and assemble?

 

Transfer files in some way (is there a utility which can create DOS format image files (.DSK) for example?)?

 

Copy and paste through an emulator?

 

Use an emulator to write and test with as well?

 

TIA!
