What To Do with Unwanted Apple II Series Computers?

I’m sure a number of you have similar concerns, so here goes.

 

I have a number of Apple II (Rev 2 and 3), and II+ (Rev 4, 7, and RFI) computers, some even with original boxes.  All work and have drives and multiple add-on cards.  I’m planning for the future where these will have to go.

Franklin ACE 100 keyboard

So after some minor cleaning and reseating chips, My Franklin ACE 100 (not 1000), is ALIVE!  Floppies were way out of speed, but that did not take long either.  Of course the foam and foil keyboard is totally dead and I will order a set of pads from TexElec to revive the keyboard.  There is an extra board extending down from the keyboard on the power supply sided (possibly an encoder board), otherwise the keyboard looks much like the ACE 1000 with the standard DIP-16 keyboard cable like on a ][+.  The ACE 100 from March of 1982 was mostly a mass produced prototype (2000 produced) and most o

Building the MMU on MAX7000 devices

In this thread: https://www.applefritter.com/comment/107057#comment-107057, retro_devices asks for help to program the MMU on some old Altera EPM7064LC44-10 and EPM7064LC68-10.I am starting this thread for that discussion.

 

The two devices are 64 macrocells, which is enough for the 58 macrocells the MMU currently requires.

 

I'm not too sure that this will be possible on MAX 7000 devices, though.

A small 2c project I'm working on...

I didn't have a working mouse for my //c. That ended earlier this week.

A tweak of an earlier design I used for Atari ST using a WinChipHead (Nanjing Qinheng Microelectronics) CH series microcontroller. The perf board prototype works great and PCB's are on the way. Most any USB HID or wireless HID (with a USB receiver) mouse can act as a //c mouse, or as an input device for a ][ or //e buss mouse card.

 

If there is any interest let me know. I'm still undecided on how to make this available.

Change ProDOS file type to SYS

So I've written a small 65C02 assembler program that I want to change from BIN to SYS.  It is assembled (with my cross assembler) at $2000, and I can run it from the BASIC.SYSTEM command line or BITSY BYE.

 

Anyway, what is the easiest way to change a file type in ProDOS?

Howto access GSBug within the GS+ emulator running on Windows 10

Does anyone know how to access the GSBug and/or ORCA Debugger from within the GS+ emulator. The 'hotkeys' for each of these usually invoke varying windows windows depending on which keys are pressed. The same problem exists for accessing the text mode control panels. It seems the author may not have 'trapped' the keys such that pressing the various 'hotkey' combinations access windows functions instead of IIGS functions.

Any help is appreciated.

Apple II Rev 0 Keyboard Power Light Switch help

I have a broken switch housing for the power light on a rev 0 keyboard.

All my replacement switches I think are 'welded' closed. I can't seem to find a way to open them so I can replace the stem/plunger with the light bulb stem.

Any suggestions.

Calling Applesoft GR routines from assembler

I used to have a document, magazine or book (well, I may still ahve it somewhere but I don't remember) back in the day which had info on how to call the Applesoft GR and HGR routines from assembler.  Basically where to JSR to do things and what memory locations and registers to set first.

 

If anyone has that or can point me to it, it would be great.  I wrote a little Applesoft program that draws a splash screen in low-res for a 32MB ProDOS disk image that I'd like to convert to assembler and make a .SYSTEM file out of.

Apple III plus disk interface pinout (DB25)

I've been looking for this, but can't find it anywhere.

I know it's basically the same as the DuoDisk connector, but the available pinouts for that leave out many of the pins, since DuoDisk doesn't need them.

Apple made an adapter, IDC26 to DB25, to use the Disk III on the Apple III plus, but I don't see the specifications for that anywhere either. Does anyone have one of these adapters?

Or, is there anyone with an Apple III Plus who would be willing to beep out the connections between the inner 26 pin header and outer DB25 connector on the motherboard?
