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!

flashing colors in games on Apple IIgs

Submitted by guibrush on January 5, 2022 - 8:26am

Hello everyone and happy new year!I have a question about games specific to the Apple IIgs. I have colours flashing on the screen when I run several games, like Lemmings, Wolfenstein3d or DejaVu. I first thought it was my TranswarpGS, my RAM expansion or my computer itself, so I tried it on another IIgs, with the same result.

Then, totally by chance, I found a program called GC.noSS.SYS16, which, when I run it, trash the screen.

Apple IIe Motherboard PCB Files

Submitted by saint on January 3, 2022 - 1:50pm

I realize there is a PCB file for making an Apple II motherboard, is there a reason for no IIe out there other than no one has put in the effort? Like some non expired copyright issue.

Cleaning up basement and selling (real cheap) A][e parts & software

Submitted by Ratso222 on January 1, 2022 - 11:09am

All original Apple stuff except a couple Transwarp, Orange Micro cards and slofware, much pirated stuff but some original; too much to list. The price is real cheap as some know who have already delt with me on Fritter before. I am on the East Coast. Have (3) 5.25 drives that need work.

For Wizard's Crown Fans -

Submitted by 6502_workshop on December 31, 2021 - 12:51pm

I recently completed one of my Apple II bucket list items and created a patch for Wizard's Crown which modifies the movement keys to align better with the numeric keypad.

The original keys were awkward to use, and chosen at a time when numeric keypads were not prevalent (1985). There were alternative key sequences that appear to have been  available, but I am pretty sure they were not chosen to save memory. The patch includes a detailed write up of my observations.

The patch is available on archive.org. The direct link is:

Strange 80 column / 64k Memory Expansion for IIe

Submitted by eggimac on December 31, 2021 - 8:40am

HiI recently got a Apple IIe with a strange 80 column & memory expansion card. At least I assume it's such a card. The only Information I see on the PCB is "Copyright 1988 MKV". No further Information on the back.

Interestingly all the chips on the board where manufactured in 1983 (according to production code labled on them).Any idea who was the manufacturer or available documentation for the board? - would be greatly appreciated.

//c Disk (A2M4050) LED

Submitted by telengard on December 30, 2021 - 10:59pm

I have one of these and noticed that the LED was not working.  Taking it apart there was no LED in the bezel.  I think this may have had a //c internal drive transplanted into this case.

I tried adding an LED as well as the appropriate cable and header (with the correct pinout after watching a teardown video) and it doesn't light up.

I'm using off the shelf LEDs, do these units use special ones?   Is there any firmware in these that might not be utilizing the LED?  Was surprised it didn't just work.   :(

Apple II+ keybaord to USB

Submitted by Stargeezer on December 30, 2021 - 9:07pm

Happy New Year all:

Got a project on the horizon and I can't seem to hit the right search terms.

I have an Apple II+ I plan to empty of all parts (I'll post here for any interested party once the project is done).

The goal is to put an Apple II+ Raspberry Pi emulator in the case.  I want to use the original keyboard with the RasPi.

What is driving me nuts is I could swear I came across a website where someone did just this.  I know there are posts and videos of people doing this to Commodore 64s.

Help me diagnose an Apple IIc Disk Drive issue

Submitted by migueldelag on December 30, 2021 - 3:33pm

Hi, second time writing in the forum.

 

I have an issue with an Apple IIc that suddenly stopped communicating with the internal Disk Drive, no sound at all, no spin, no read/write. The computer boots and beeps and shows "Apple //c" and "Check Disk Drive" message. Got to add that the drive used to make sound, sping and read/write intermittently.
