Apple II plus colour problem in text mode

Submitted by johndegroot on January 10, 2021 - 11:30am

I’m getting back into the apple II game after 30 years away from it. I purchased a clone and a real apple about a year ago. The clone works fine. The real apple has an issue in text mode on a colour monitor (Commodore). In HGR mode, the text is crisp with the normal colour fringing, but in text mode, the colour is so overdriven that you can’t read the text. I disconnected the 4.7K resistor to Q6 (colour killer transistor) and the text is the same in text mode or HGR (which it should be).

9-inch Color CRT display that supports 80-col text

Submitted by old_hitech on January 10, 2021 - 9:59am

Does anyone know/have a 9-inch CRT monitor that supports Apple II color graphics and 80-column text? I have a 9-inch color monitor, but it does not support 80-col text. I also have a Color Monitor IIe that works great - color graphics and 80-col text, but it is a 12 or 13 inch display. I like the old-school look of having the monitor and 2 Disk II drives on top of the Apple II case and need 80-col support. I know I could use an LCD screen, but it does not provide the old-school system look.

Need help fixing stepper motor issue with Disk II floppy drive

Submitted by Magnificat on January 10, 2021 - 8:34am

Hi All, I have a Disk II floppy drive that was purchased a while back and was NOS at the time but of course arrived DOA so i started troubleshooting it a whlie back. I have a working disk II here i use as a test machine to move parts/boards, etc..

What it's doing is.  on turning on the machine the stepper flapps a bit, and the primary motor spins the disk but the stepper motor never engages and starts moving forward/reverse to any tracks on the disk. 

What i have done so far.... 

1. moved the logic chips from working system to non working. no change.

Apple 5.25 Disk controller card

Submitted by martin72 on January 8, 2021 - 4:18pm

Hi, I have two of these cards that don't work well. When I place one of them in the Apple IIe I get only vertical blocks at the screen and the keyboard doesn' t respond. With the other the Apple IIe starts up but the duo drive does nothing.  The duo drive is ok because with another Apple IIe it is working well. My question: where can I find the documentation (schematics etc) of this controller card (655-0101) or can someone help me with a servicemanual or schematic?

GS-OS 6.0.4 Weird sound problem

Submitted by Verault on January 8, 2021 - 3:57pm

So for some reason the SOUND icon under control panel is not showing up anymore when I open the control panel from GSOS. If I navigate to the System folder, then CDevs, I can find the SOUND module there. If I run it from the CDevs folder it opens... but when I pick any event to choose a sound for, it will say "not assigned" and when I try to choose one to populate it with it will give me a blank menu with no choices. How do I fix this? its weird and annoying. I tried reinstalling the sound module from the install disk, this didnt fix it.

Lower case for pre Rev 7 motherboards

Submitted by DeanClaxton on January 8, 2021 - 12:05am

Hi all,

 

just letting you know that if you wanted lower case on a pre-rev 7 motherboard, ROMX 2513 is ready! The same 16 fonts are available as per the ROMX  2316B.

 

Blog here : https://theromexchange.com/blog/8th-january-2021

 

Caveat - you'll need a ROMX module to go with it :)

 

Cheers,

Dean
