NEXT PATIENT - Performa 200 (Classic II)

#1 Sat, 29 Dec 2007 - 05:25

I am slowly going through my Compact Macs to fix known issues and check things over...

My Performa 200 starts with jail bar lines. Thinking a possible RAM issue I pulled the two simms, now I get a checkerboard!

Can anyone point me the right way? I have a couple of Pina books but unfortunately neither covers the Classic II :O

I still would love to see a performa 200 in real life.

This is always a good starting place from which to troubleshoot compact AIO misbehaviour. Their common use of one-bit (monochrome) 'vampire video', ie that system RAM is used for video RAM, also gives them several failure modes in common. It will be obvious where the advice is specific to SE/30s, and will not apply to the Performa 200/Classic II.

Good shooting!

Thanks equill. I have seen that site before and found it to be a good source of information.

I pulled the motherboard out and noted some white residue, so it got a bath last night. I reassembled this morning, and it boots up

(at least for now)

This may be the first Compact that I have to replace some capacitors in. Yikes, my soldring skills are pretty rusty :O

System 7.1 with 10 MB RAM and what appeas to be an 80 MB HD.

This must have been a factory refurbished machine - original Serial Number label has been replaced with sticker saying SR REFURBISHED with a bar code and what I assume is a serial number.
