anyhow... I'm not able to switch to the 80 character mode... as the system always booting the Bitsy.boot file...

Is there anybody that could give my some hints booting ProDOS 2.4.2 in 80 character mode, please ?

Apple II Plus No Video, No Beep, but Power Light On

Submitted by fl3tching101 on February 13, 2018 - 11:06pm

I recently bought a working Apple II Plus from eBay and it worked great. However, a few hours later I pulled the top off while it was on, and the video signal cut out. I turned it off and back on again and now only the power light comes on. No beep on boot or video output. Several Apple repair manuals I have found give a list of a few chips that may cause this exact issue. These are the 74LS00, 74LS174, 74S86, 74LS02, 74LS153, and 74LS195 chips at locations A2, B1, B2, B13, C1, and C2. There's a slight problem in that at positon B1 my board has a 74LS175 chip.

Advice requested for repairing disk image on CFFA3000

Submitted by skipper1947 on February 4, 2018 - 10:07am

The disk image that my BBS runs on (Dura Europos) has developed errors. I fear they may be the result of adding the Fast Chip IIe and upgrading to GBBS Pro v2.14, though I hope that is just a coincidence.

I ran Mr Fixit, but it doesn't touch the errors. I want to replace the .po disk image with a clean one, but so far I have failed.

Flat screen TV compatability

Submitted by wment on January 27, 2018 - 11:00am

I recently purchased a flat screen TV with a composite input for use with my retro Apple Computers only to find it does not work with the Apple composite. I have a Sharp 32" that works just fine with the Apple but the 19" Insigna that came from Best Buy does not work. Specificity it is a Insignia NS-19E450A11.

Wanted: Uthernet or LANceGS card!

Submitted by 8bit-Dude on January 26, 2018 - 11:35pm

Hey guyz,

I have just posted about an online game which I am developping here.

To debug the online gameplay, I am using AppleWin's uthernet emulation. However, I do need to test that it works properly with real hardware!

In the past 6 months, I contacted Glenn at a2retrosystems several times, but it seems that he has a lot going on lately and did not respond.

Does anyone here have a Dithertizer video card?

Submitted by macnoyd on January 25, 2018 - 4:54pm

I'm looking for a .dsk image (or the likes) of the software that runs it.
Can't find the software for it on Asimov and other sites, only the photos and manual.
A reference to D/L would be much appreciated! Thanks in advance.
