Is it possible to convert a data cassette to PC readable format for emulator?

Submitted by SorcererApp on September 21, 2023 - 6:37am

Hello! Thanks again for the host of the forum providing this, a place for hobbist to share ideas and ask for help.

 

I have got an apple data cassette from a family friend who has passed away a few years ago. I think it is nothing important but just a memorial for my family member.

I just wonder if it is possible to retrieve the data to a pc readable format like dsk format that converting from apple diskette?

IO error on Apple //e

Submitted by Research Subject on September 19, 2023 - 2:45pm

I am occasionally getting an IO ERROR when executing commands, even when I successfully executed other commands before it gave me the error. If I check the kernel using CLOSED APPLE+CONTROL+RESET, it gives me the error message "IOU FLAG E5:1". If I check the kernel using the same method before the IO ERROR message appears in the console, the diagnostics tool tells me KERNEL OK.

New Machine = new questions

Submitted by Stargeezer on September 18, 2023 - 2:39pm

Hi all:

I was fortunate enough to pick up an Apple IIc + with monitor for an amazing deal. 

Things look good so far but I was running into some ADTPro issues, I think its cabling.

But it got me thinking.  What about picking up an external 5.25" off eBay?  Can the IIc+ use any of the 5.25" externals, some on eBay say for Macintosh.  Is there a difference?

The other thought was, can a floppy drive from a IIe or II+ be adapted to work?  My gut says unlikely as I am willing to bet the bus is different.  Just a guess, but I suspect the external floppies are SCSI.

Help with Apple /// format disk error #21

Submitted by old_hitech on September 18, 2023 - 12:39pm

I am trying to fix an external Disk /// drive that gives a "Format error #21. Internal program error." Message when I try to format a diskette. When I format the diskette using the internal disk drive, the disk completes formatting with no errors. I've looked through my Apple /// manuals and did a Google search, but cannot find what this error means. I've cleaned the head on this disk drive, have cleaned the head mechanism rails with isopropyl alcohol, and have replaced the ICs on the Disk /// Analog Card from a known working Disk II drive.

Silly issue with Floppy Emu C and IIe

Submitted by dhoggan on September 17, 2023 - 11:46am

Hi all,

 

I'm really sorry to post what is likely a really obvious question, but I simply cannot work it out - all the more annoying as I am sure I have had this working at some point.

 

I have a Floppy Emu model C  that I've recently put into one of PTB's wonderfully retro Disk ][ cases. It works wonderfully on my Apple IIc with the provided internal/external drive switcher. But,  as it looks like a Disk ][ it makes sense to use it on my IIe. The problem is I cannot get it to work!

I tested all chip

IIe howto create 80 col windows and restore desktop on window close

Submitted by sbaker51 on September 13, 2023 - 4:54pm

The question is not so much related to how to create a window, it is related to how to restore the underlying desktop screen when the window closes , which in this case means that the active cursor moves out of the window and back to the full screen desktop.

This code example shows one way a 'scrolling window' can be created.  Please view the attached 'wintest2' file to see what this does.

Undocumented Apple IIgs ROM Found

Submitted by Whiskey Tango F... on September 13, 2023 - 4:12pm

Hello there- found this forum while searching around. I recently purchased a GS logic board, still sealed in its electrostatic plastic. It seems to be a stealth board, actually. Anyway, I noticed the ROM chip has an IC number that doesn't match anything I've found online. ROM0 is 342-0077-A, ROM1 is 342-0077-B, and the ROM3 chips have their own separate set of numbers. Well, this chip happens to be 342-0077-C. If "9235" is the datestamp of the chip, then it would have been manufactured in 1992, after the ROM3 was released.

Apple IIGS display problem

Submitted by Wawavoun on September 13, 2023 - 2:38pm

Hello there,

I have an Apple IIGS connected to a lcd tv via the scart (peritel) socket.

With other computers (for example Apple IIe + Chat Mauve or CPC6128) this socket is ok.

I get the the subd15 to scart cable from England on Ebay.

The problem is that sometime the tv loose the vertical sync.

The display is stable and perfectly looking for some seconds and then he start to slowly move vertically then stabilize again and so on....

I carefully check and move the cable searching bad contact but everything look good.
