Cleaning Slow IIe Key Switch

Submitted by nick3092 on January 13, 2022 - 3:45pm

I recently acquired an Apple IIe. Everything is in good shape except the caps lock liked to stick down, and one of the arrow keys doesn't like to pop all the way up/is slow to pop up. It doesn't constantly actuate, so it's usable. But kind of annoying.

 

 

I flooded both with QD electrical cleaner down the stems while working them up and down. It seemed to have helped the caps lock. It now promptly pops up when you disengage it. But the arrow key is being stubborn.

IIgs ticking noise from speaker when using GS/OS

Submitted by Mrarkus on January 13, 2022 - 5:32am

Forgive me if this is a common question, I've googled a bit and all I could find is threads about clicking noise from drives.

 

I have a ROM 1 GS, with new power supply and CFFA3000 card. The computer is perfectly quiet when using drive emulation with CFFA. However, when I connect my recently acquired Apple 3.5" drive and boot GS/OS, there is a ticking noise about twice a second through the speaker. The sound dissapears when selecting a menu, or holding the mouse button in general. Any ideas?

Mountain Computer ROMWRITER Card

Submitted by Stargeezer on January 11, 2022 - 8:29pm

Evening All:

So two questions for everyone.

1) Has anyone seen a MountianComputer ROMWRITER card for sale anywhere?  There was one on eBay a month or so ago and I just wasn't in a position to act and purchase.  If anyone comes across one of these, or another brand, please let me know.  I would also be interested if anyone has a schematic for these cards to build a clone.

Hi Folks,

 

Just some fun here...  I grew up playing Ultima II and I was always really curious about a couple of walled off areas in the game.

Apple ii plus capacitor replacement

Submitted by warby on January 10, 2022 - 8:33pm

I got my Apple ii plus up and running and ordered a capacitor replacement kit for the power supply. I was getting ready to start the work and when I opened the power supply, I found it to be prestine. I understand the capacitors can leak and dehydrate over time. But I also am having trouble convining myself to fix something that aint broke and looks perfect.

So before I do anything, I just have to ask: do I really need to do this?

Here's how things look:

Floppy Emu or CFFA3000?

Submitted by clamm on January 10, 2022 - 7:18pm

Hiya folks,

 

I am trying to decide between purchasing a CFFA3000 or a Floppy Emu. My configuration is a stock IIGS with a 3.5" Unidisk and 5.25" drive. Ideally, I'd like the computer to attempt to boot from the 3.5" Unidisk and then the 5.25" and then the Floppy Emu/CFFA3000 and retain the ability to read/write to either drive as necessary.

 

Is this even possible? I am rather confused by all the limitations on the daisy chaining and I don't want to make a mistake and purchase all the wrong stuff.

Are 2HD diskettes completely out of the question?

Submitted by fegos on January 10, 2022 - 4:04pm

Hi, i recently got back with my 80s apple iie.    It has a duodisk drive that i cleaned and speed calibrated and it works with most disks.   I also had an empty NOS box of 2HD diskettes.   I notice that they dont format.     I read in here that HD disks are unreliable.    Should they not work at all? as that is the case on my duodisk.  Or is there something else calibration wise that should be done to the duo disk?  I wanted to know if this HD issue is as binary as i see it on my unit. thanks
