      Just think, having a Quadra 950 in 1992 would be like having a Mac Pro today… except with more slots, more expandability, and on-board SCSI!

    • Hello all, I recently acquired a Classic II and am trying to get in running. Currently it displays just garbage on the screen, or vertical lines. I've put the motherboard through the dishwasher and have a new cap set on the way, even so the fluid leaks were very minimal on the board and it appears to be in good shape. All to no avail, as it still displays vertical lines. I decided to test the power output, and it is at 11.7v on the 12v rail, and 4.8v on the 5v rail. Does the analog board need to be recapped as well? Thanks for any advice!
    • I've removed all the caps from over 20 IIcx boards without lifting any pads using the two soldering pencil  method.     I think it has a lot  to do with what one is comfortable with.
    • Nice work with this!    I have a Keyspan serial adapter sitting around...wonder what it would take to get an ImageWriter II going on Catalina? 
    • The battery has now been rebuilt   I ended up using only 4 cells, this was mainly because I wanted plenty of space for wiring (I have found in the past that it can be quite a tight squeeze to get the cells back in the pack when you are just soldering tabbed cells together) but also due to cost, the 8 cells I brought cost over £40 with shipping and I really didn't want to spend that on a iBook I'm only going to be using a few times a year   The first Issue I found was that those nice slot's in the plastic separators in the pack I used to run the wires through turned out to be there for the edge of the top case to clip in to so all my nice neat wiring had to be moved to allow the pack to be reassembled   And with that all taped out the way the pack can now finally be reassembled   The pack is now back in the iBook charge cycling and seems to be working fine One issue with using just 4 cells is that it may shorten the life of the cells, samsung's datasheet says the ideal charge current of the cells I used is around 1350ma with a max charge current of 2600ma, the iBook charges the pack at a maximum of about 2250ma so significantly above the ideal value. I'm not sure how effect this will have in reality though
    • Classic II requires the later one 99% of the time, but I did once see a Classic II with the earlier connector. My guess is that it had been cobbled together out of an older analog board and CRT, probably from a donor Classic I.   Every SE uses the older style CRT, which are super common. They're also one of the most reliable parts in the whole machine unless the neck gets snapped while working on them.
