I've always liked Tektronix oscilloscopes. I used many at work over the years. I currently have a 475A, TDS310 and TDS380 at home. Your 11401...

Thanks Doug, That photo shows a more professionally made fan assembly, but it seems even crazier than what I am working on. The filters are on the...

VB.Net is actually a pretty good product - I've been using it on a daily basis since .Net 1.1 hit the street. I've found that VB6 users that hate...

Thanks Jerry, The document shows the back of the RX01 on page 2-5. The 80 mm fans on my unit are to the left of the filters. The fans are mounted...

I have 2 RX01's and an RX02. I am on a road trip right now so I can't get any photos until I get home. The first of the RX01's I got was in the...

Have you looked at EK-RX01-OP-001_RX11UM_Nov76? Jerry

I was unable to find a diagnostic ROM for 5150. The only ones I saw were for XT (5160). I've been through a pile of XT and PC motherboards in the...

The DC power pod in the back of the computer provides 12 volts DC for the computer. By pushing the button under the pod it will pop out and you can...

I can, but my completely original RX01 didn't come with a fan on the back.

I wonder if I could use a Tie Plate https://www.homedepot.com/s/tie%2520plate?NCNI-5 and maybe I'll just get lucky with the hole alignment? If not,...

If the motherboard can't properly determine the CPU speed at 200 MHz, it very likely doesn't support it. Many motherboard vendors in the 1990s...

You were lucky to find a local fix it shop still in business. All the ones I knew of including TV and appliance repair shops have all closed up. ITs...

I am looking at my SE and FDHD and they both have the vertical expansion cutout and vertical mounting points. Floppy cutout is the same as well.

The only CRT based digital scope I have is this, but I really like it:

I have both a regular SE and a SE FDHD and they're both identical in terms of board placement. The only difference is the FDHD has different holes...

Could some kind soul with a unmolested RX01 please send me a photo of the back of the unit. It really bothers me that the RX01 which came with...

Gorgeous. Going to diagnose my newly acquired Portable 1 that has a dual 360KB drive setup and a HardCard (might pull the data off of it if it...

I'm enjoying reading this thread. I have very fond memories about BASIC as it was, as many other people, my first contact with computer programming....

I drilled a 1mm hole in the remaining knob and screwed a fine srew into the hole. Than it was possible to pull them out.

The first ever ABS print wasn't great. The trim panel bracket was warped on both sides. After reading about possible causes I managed to do a perfect...

These sorts of plastics are super resistant, like Nylon, to any form of chemical adhesive. If I were fixing that I would find a way to clamp both...

I use HFVExplorer and WinImage. With HFVExplorer you can copy stuff into a blank Mac disk image and then write it to disk using WinImage.

Happy to help! Let me know if any more pictures would be useful. I wonder what the trick is for removing the feet without ruining anything. They...

Yeah, don't use super glue on that. I had no idea it was called Delrin but that looks like the type of plastic that never adheres correctly with...
