I picked up a Compaq Portable from a fellow who was also selling a Kaypro II I bought for my father. A few months later I found someone selling a 5160 for cheap...I didn't really have a need for it, but I just had to have the Compaq Portable and the 5155 running side by side.

Wow that's a project! How many pieces and screws and bits do you have scattered on your desk now? :) That keyboard restoration was epic, I'm not sure I would have had the patience to do that! The capacitor soldered on the mains socket should be to avoid sparks when the mains cable is plugged in. You'll see it on modern PSUs as well. Something @TheTechknigt taught me :)

Thanks for the video, I openned up my 5155 PSU to check for Rifa caps, thankfully none there (some PSUs have them on the filter board apparently). At 13:28 can clearly see that the drives are bolted into slots. You only need to remove one long bolt from the other side of the floppy drive and just loosen the other three bolts with a spanner. The floppy drive then slides back and can be removed (if there are no ISA cards in the way) - no need to remove the CRT.

I've just got my hands on one of these, before I open it and start to clean up are there common failure points apart from the tantalum caps? Great news about no RIFA though

14:50 Yes, the drive cage is indeed a bit too narrow compared to a regular size computer. What I did with my 5155 is to sand the sides of the front plate of the drive. It doesn't have to be perfect because the sides are covered by the 5155's front panel.

I enjoy replacing the foam in Model F keyboards, but it's very difficult with the 5155 Model Fs. The plates are made out of a lighter, more flexible metal than the rigid steel assemblies of every other Model F. This means new foam does not compress as the metal isn't strong enough to do this. The amazing key feel of a Model F comes from the plates and foam pressing the switch housings tightly against the PCB.

Watching the disassembly of the 5155 was a painful kind of entertainment - what a lot of frustrating design decisions. Though maybe slightly easier than glued-together modern garbage. Really appreciated seeing the servicing run on the keyboard though. I am working on restoring a Model F 122 and not gathered the courage to tackle the foam yet, due to it being totally disgusting. A little more courage now. Spacebar advice sure is handy too. Thanks.

I have never seen a Model F restoration video, so seeing this was awesome. Luckily the foam pads are available according to google, just pricey. Also, the belts are melting on my FDDs for my 5155 so Console5 now stocks those. And yeah, the drive cage opening is too narrow before the later XT/AT standards defined things. the HDD probably has a stuck stepper because it was flashing an error code in your video. The other problem I am having, the black coiled keyboard cable is also melting so i need to fabricate a replacement for that.
