I played a little bit today. Got to 24k and was about to enter my name but it crashed. Was on a IIfx, version 2.9.3b I think? Maybe I was dreaming it. :ROFLMAO: This is hard. I am lacking skills.

Finally rebuilt the battery in my PowerBook 5300c (documented here) Wish I had better pictures but user error (deleted on accident... ugh). Working on a PowerBook 540c battery but the EMM board is not working right so debugging that now.

Hmm, really interesting. So I finally got around to recapping my M1212. I decided to recap because I was getting some wobbling on the screen and I checked and reflowed most of the solder joints with no improvement. I replaced all the caps and tried a test, and the wobbling was much worse. It...

This is like Sylvester Stallone in the Rocky movies where he has those training montages before the final match. :)

I finally entered the right search terms in Google to get to a service manual for the NEC 52V. I was hoping to find a hidden service menu within the OSD and sure enough, one exists. I was able to enter the proper key combination to get into this service menu and there were multiple settings to...

Not yet... on my todo list still. Maybe get a chance to crack it open and take a look inside this weekend. The stock battery I have does show signs of corrosion on the outer connector so not sure what I'm going to find inside. But at least in terms of checking out the battery size, should be no...

Yup!

Ok so I got the set of twelve 4/3A 3800mAH NiMH batteries directly from Tenergy. Unfortunately, don’t have pictures as in the midst of transferring some files around on my main computer, I deleted them on accident :( Anyhow, it was really really straightforward. I hot glued together packs of...

Thanks, that did help. Not perfect, but better than it was.

Hoping someone well versed in video/LCD panels might be able to educate me. I have four LCDs that I use with my 68K machines. One is a 15" Samsung (512N) and the other three are 15" NEC 52Vs. All are native 1024x768 panels and can operate in both 60Hz and 75Hz vertical refresh rates. The...

Thanks for the tip. Will certainly do that before powering it up.

Oh you guys are just evil… Just purchased one for $8. Hope it still works but at $8, was worth a shot. Haven’t had one in years… but it’s worth the price of a matinee movie just to hear the printing again.

Well wait a bit on the 52V. Just noticed two of them have some identical contrast issue (the gamma seems too high) on my IIci. Need to play with it some more.

Unbelievable how weak it is.

This is why I have been gobbling up some older LCDs from NEC, Samsung that support 67Hz as well as 1024x768 at both 60Hz and 75Hz native and so I can get 1:1 from the higher end video cards that drive at 1024x768. I’ve got a Samsung 512N that works awesome, and three NEC 52Vs (one of which has...

Mine also came with 815-6035, the top one.

Learned a few things today. Boot on plug in - I found it strange that my 5300c would power up immediately after I plug the power in. Shouldn't be like that but that was the behavior. I saw the same thing on the 5300cs previously so I did not think it was something specific to my 5300c. Well I...

Did not help. Tried it with the stock SCSI drive and same problem. I think it's the drive. Will have to take a look at it in more detail at some point.

I haven't had a chance to try the old IDE drive yet. But looking at the references you linked, it looks like that modification is necessary to support devices not meant to work on the PowerBook. But the VST Zip drive I have was made specifically for the PowerBook 5300/190. So my guess is this...

Can't wait to see you get the systems working!! 👍
