Apple IIc keyboard problem

Submitted by papalapa on October 30, 2021 - 6:46am

Recently I bought an Apple IIc with german keyboard and after some days of use the RETURN, ENTER and ARROW UP keys stopped working. I opened the Apple IIc case, unconnected the keyboard flat cable and visually checked for some damage, but all seemed to be correct. I applied Contact Cleaner  (zero residue) to all the switches and after re-installing the keyboard again all the keys started to work.

 

Today, after a couple of weeks using the Apple IIc, the problem  has come back.  What can be cause? Flat cable or keyboard controller chip maybe (which one in this case)?

IIc Plus RAM upgrades

Submitted by KG7PFS on October 29, 2021 - 10:32pm

I understand the Apple RAM upgrade for the IIc won't work in the IIc Plus unless I replace the PAL chip because of a timing problem. Where do I get the replacement PAL chip?

There seems to be a rumor that later IIc Plusses were sold with a 256k RAM expansion installed. Where did this go? Where can I get one?

wDrive features

Submitted by papalapa on October 29, 2021 - 2:30am

I have my wDrive connected to the Apple IIc throught the BMOW disk switcher that enables to boot from it. After somes days testing and loading disk images succesfully, I have two questions:

 

1) How can I set the time that the display background light is turned on? Now is turned on all the time, but when used with my Apple IIe I think to remember that it turns off after a few seconds since the last disk access. No mention about this in the manual then, I'm not sure if is possible or not, or maybe if it's a firmware issue.

ADTPro - Audio and SSC issues

Submitted by heyme123 on October 25, 2021 - 5:13pm

I have been trying to get ADTPro working now that I have a good working Floppy drive.  

Both Audio connection and SSC connection has the same issue - garbage text after the first couple files listed when doing a remote directory.

 

I can send data fine,  I have even sent a copy of a disk back to the computer and ran it in AppleWin.  Using the DiskServer website, i can send disks via the audio connection.  Just not with ADTPro.

Adapting the Apple IIe mouse?

Submitted by timetraveller on October 24, 2021 - 6:04am

I'm considering a purchase of an Apple IIGS. I already have an Apple IIe and mouse.

Can the Apple IIe mouse be adapted to work with the Apple IIGS by using an adapter to convert the DB-9 connector to the small Din connector?

Apple II monitor & flyback

Submitted by MacFly on October 22, 2021 - 6:00am

My trusty Apple // monitor has given up (A2M2010P European/PAL model). The root issue seems to be a dead short between the #1 and #7 pins of the flyback transformer. That's a short between a primary and secondary winding. Not good.

 

What a bummer. It's still got a bright green phosphor CRT, decent, unscuffed case - and not too much yellowing. And having my original green CRT with the machine is somehow part of the whole experience of running the machine.

Trashpicked Apple IIe - vertical bars on screen and graphical glitches

Submitted by ellindsey on October 18, 2021 - 10:27am

Several weeks ago, I found an Apple IIe lying in a pile of trash and broken furniture on the curb a few miles from home. I took it home and completely disassembled and cleaned everything, and replaced the RIFA filter cap in the power supply just to be sure. Other than the keyboard, everything seemed to be in good shape, although there was some corrosion on sockets and internal connectors.

Apple IIc disk drive

Submitted by papalapa on October 17, 2021 - 2:54am

Hi! Recently I got an Apple IIc and all is working except the internal disk drive. I passed the built-in checking (Ctrl+Open Apple+Closed Apple+Reset) and after around 1 minute it says "System OK", but when I put a disk inside during the startup (and even withtout any disk inside), a noise can be heard and the message "No bootable device" is shown.
