Apple iic not formatting or duplicating disks

Submitted by pga7020 on November 26, 2020 - 1:51pm

I recently purchased Goldstar  M-2D  5.25 floppies to format and make duplicates of my ProDOS System Utilities disk that came with the Apple iic. When I attempted to format the Goldstar blank disk, I received this message on the screen ( see second pic). Then when I was attempting to duplicate the Apple Utilities Disk, I received this message on the screen ( see first pic). I tried different blank Goldstar floppies, but they all ended up with the same result. Are these Goldstar disks bad or is there another issue?

Floppy Disk Labels with Good Adheasive?

Submitted by mutant_pie on November 25, 2020 - 9:13pm

So, like many here I imagine, I have labeled my floppy disks (both 5.25" and 3.5") with the labels that came with the disks and those are fine, but not easily run through a printer, and they have a certain look (usually with horizontal lines for hand writing above).  I have also tried to use printer-friendly label sheets to make nice typewritten/graphiced labels.   But the adheasive on those is terrible and they don't stick well to the plastic surfaces of the disk shells, especially the pebble-textured 5.25" floppies.Has anyone here found a good source of printable, high-adheasion labels th

HFS reliability with GSOS

Submitted by michael48937 on November 24, 2020 - 10:01pm

I seem to run into a lot of trouble with just basic file copies using HFS partitions.

 

Currently I'm organzing some images using GSPlus to burn back to a CF card.  I have various sizes (200MB, 2GB) of HFS partitions and while they seem to work at first, after a few minutes GSOS often complains the disk (image) may be "physically damaged" and can't complete the operation.

 

Usually there is a deletion involved when the errors start (empty trash or overwrite a file).

Apple iic not duplicating disks

Submitted by pga7020 on November 23, 2020 - 9:18am

I hope someone can help with this issue. My Apple iic will not make copies of the utilities disk or any of the AppleSoft disks. I was trying to copy the utilities to set the modem to 1200 baud as standard is 300 baud. I am using brand new double density Goldstar 5.25 floppies. When attempting to save, the monitor screen presents a strange image. Any thoughts? Thanks

ADT PRO 2.0.3

Submitted by pcbastler on November 22, 2020 - 11:59am

Hi,

 

I have a problem with ADT Pro. I am using Version 2.0.3 with an Apple //c and a Mac with Catalina. I am using a USB to Serial (CH340) and a custom build cable (pinout taken from the ADT Pro website).

Bootstrapping works fine with my setup, but I cannot get the application to work. When I try to receive a file from my Mac by pressing the "R" key (or selecting the appropriate menu option) it just gets to an error "HOST TIEMOUT/PRESS ANY KEY TO CONTINUE".

Marinetti with Uthernet on GSPlus

Submitted by michael48937 on November 19, 2020 - 8:16pm

Has anyone gotten this to work on an emulator (GSPlus) without a crash on connect?

I would like to get it working prior to buying an actual Uthernet card.

Franklin Ace Floppy controller IC

Submitted by mnaaron on November 17, 2020 - 1:07pm

Hi, I'm looking for the floppy controller IC to repair my Franklin Ace.  I've narrowed it down to it being the reason my floppies don't work correctly... they read just fine, but they won't write.  The drives work, I can tell because if I plug them into a Disk ][ controller, they work great.

 

The IC I'm looking for is a USI chip, I think the part # is 4003000

 

If anyone has one from an old machine, please let me know.  Thanks!

Noisy video signal on Apple II clone

Submitted by berni79 on November 15, 2020 - 4:39pm

Hello,

I hope this exact problem was not discussed before. I tried the search function, but I am not able to limit the results to the Apple II forum.

 

I have a relatively good working Apple II: boots, loads software and games. However the video signal is bad, there is a lot of noise in the signal.

I am able to get picture on my monitor, but it is noisy (obviously) and has a bad contrast ratio between black an white.

 

I tried to diagnose the problem and attached an oscilloscope to the internal aux video connector:

Cassette interface on Apple IIc or Apple IIgs?

Submitted by eric42 on November 14, 2020 - 10:49pm

Is there any way to connect a cassette player to a IIc or IIgs?  I have a couple of Apple II cassettes that I'd like to be able to use with my IIgs (prefereably) or IIc.  Is there a cassette interface card that would work on the IIgs?  I've looked around and haven't seen anything but maybe I'm just missing it.  I'd appreciate any help!
