That looks a lot better!!! All we need to resolve is horizontal width at this point. I know the mod talks about adjusting the Horz deflection voltage as part of the mod. If you raise or lower the monitors b+ volltage this can cause the monitor to adjust In Size, but yur picture looks good.if...

It looks like your pincushion settings are out of whack. Did you try adjusting the horizontal bow potentiometer(pb)

Interested in one if your doing a re-run!

If you had the install media you could always format the drives are re-install the os. I'll be in Austin on Thursday. What are you looking to get for the g4?

The power supply is built into the analog board. Not sure what mods have been done to the machine considering it has a powerpc board in it (from previous posts). The cc analog doesn't support 640 without mods. Wondering if it might be better to get a 575 analog and do the mod to fit it (since...

Lol! Welcome to the club!

Yeah... the case will come apart and expose the drive. There are some videos on YouTube that explain how to clean and re-grease the drive. Plus they'll explain how to replace the broken gear too. You'll probably have to purchase a new gear for it. Those can be purchased on ebay fairly easily...

Sounds like your gonna have to pull it apart and see if something is binding. When you use the pin/paper clip to eject the disk do you feel the release lever pushing back and the disk is just not ejecting? Make sure to push the release as far back as you can. Odds are good (if you haven't done...

Finally got a day to start on my IIci pcb. It's coming along nicely (if i dont say so myself 😁) Thanks again Max1zzz for the amazing pcb!

I can't say for certain it's a 575, but it has the same layout as one (albeit a.little rusty)

Foldover and vertical compression like that is usually indicative of a cap out of tolerance. It could just be coincidence, but since your problem didn't appear until you replaced the pots I would check their resistence first. Problems always have a funny way of being at the last place we...

I'm not a lisa expert, but that looks like you have bad caps on your monitor chassis. Your probably gonna have to cap the monitor. That or go through the chassis with an esr meter and see if you can find the bad caps/cap. I'd start in the vertical deflection section.

That or I'd pull the transformer and verify it's bad with an lopt tester. They used to sell a cheap kit you could build (dick smith)

Can't do that. That's a center tap and it's feeding both sides of the outputs. If your looking for a transformer you'd be better off buying this... https://tinyurl.com/2a7u9cee

Welcome to the site! I was one of those 129 so I apologize. I actually started watching your Javascript script stream and forgot to come back to say howdy. I too haven't programmed in Pascal since high school, so I probably won't be any help. My pacman chops were lacking (great port btw!)...

You could use a logic probe to verify activity. You just want to make sure your pins are getting data from the swim. If your in my area I'd be happy to help. In the interim you could just build your drive images on another machin, but i would really miss my floppy emu. And... since you...

I'm wondering if someone cut that trace on purpose. Hmm Scope time. Verify each of your pins are correct (sounds like you've done that). Verify all voltage and gnd pins are good. Verify your enable line is right (active low) and that read data has activity.same with all the other lines After...

You can desoldrr the header pins, or... if you don't care about looks you can just run a jumper from the inductor from the top of the board to the bottom of the board. It would be a long run, but easy to do.

Cool. Looking forward to trying it. Thanks!

That's fine. It.say kernal okay on an unenhanced iie (doesn't have the upgraded processor). Your sound problem could be as simple as a bad speaker or it's just not plugged in. Make sure the 2 pin connector is seated correctly on the speaker out pins (look under the keyboard)
