Hi all I was getting one of my spare 5150's ready to move onto a new home when it failed It was in the middle of booting, when it died to a black screen. Next power up, it sat on the blinking cursor for 5-10 minutes before I got bored and killed the power. Every subsequent power up, it shows no...

Hi all Recently received an IBM PS/2 Model 80 that I'd quite like to revive. Sadly it is showing no sign of life at all. The PSU is good, as it boots my model 60 no problem and shows good voltages. I have swapped out the CPU, tried both memory "cards" one at a time and verified that the code on...

Hi all Fairly simple question I hope! Does anyone know when the 5150 went from using single sided drives to double sided drives? I have a fairly early 5150, two screw cover, black PSU and 16-64k motherboard. It came to me with a pair of half height 360k drives and a MFM hard drive in it, which I...

Hi all, Hope this is ok here. I've got an IBM 5151 monitor that is exhibiting some strange behaviour. It partially works and shows what it should for 1/2-1 second at a time, then the picture goes crazy, before settling down again. I'm genuinely unable to describe it properly, so have taken a...

Hi all Now I have my new 5150 functioning as it should and getting towards where I want it, having built an XT CF and Adlib clone in the last couple weeks, I want to turn my attention towards the MFM HDD and controller it came with. The hard drive is a "Microscience" HH612 10mb drive and the...

Hi all Been browsing topics on the forum for a while and decided it really was time to sign up. Based in Somerset UK and main interests are PC and compatibles, 1981 to 2000 (Plus the obligatory Commodore 64). Started back tinkering with them 18 months ago with stuff from around the P3 era, as...
