My Model 4 works, but not the 2nd drive. Head moves 1/2 way and then stops. I found the head frozen in the 1/2 spot, and with some work, got it to move freely, but it is not yet happy. Does anyone have a spare drive they would be willing to sell? Contact me with private message, thanks.

I'm trying to complete an IBM 5150 but I need the Monochrome & Parallel board. IBM called it the "IBM Monochrome Display and Printer Adapter", part number 1504900. Many people removed these boards and replaced them with the color adapter cards. Hopefully someone has one laying around...

I'm restoring an IBM 5150, from 1982, with the 63 watt black power supply. This is a two FDD, 16-64K MB unit. It arrived with 29 years of dust inside. Before applying power I have totally cleaned everything, including the inside of the power supply, taking everything apart, and even garden...

I have two IBM Monochrome monitors, model 5151. One appears to be working fine, and a second can not use up the full CRT screen, even when I have the H-Size pot all the way to the max. When I say full screen, I mean leaving a 1/2 gap on all 4 edges. The bad monitor when I first turned it on...

I enjoy restoring old PC and Teletypes and thought people here might find a tool I created useful. It is an Online Bookmarks Manager that has some interesting twists. It is not for social networking or anything like that. It is just for high-speed use of bookmarks to get around the web. It...

I have an IBM 5151 monochrome monitor that has not been used for many years. I cleaned it up, inside and out, and turned it on using the B&W/Parallel card in my IBM 5150 PC. It worked, but the 80x24 character image only took up 60% of the screen's real estate. I adjusted the V-Size control to...

I saw the si.exe program from Norton Utilities V4.5, called SI.EXE. It appears to show what's in a IBM 5150 system. Any ideas on where I could get a copy on 5.25" disks?

I have an Otrona Attache computer that works, but I have no disks. Is there anyone you know that has an Otrona Attache computer with disks, and who would be willing to copy them for me or show me how I can create my own. I believe my machine is an Otrona Attache PC and not the Otrona Attache...
