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.

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.   :(
