Recently got me a Compaq Prolinea 4/50 as I liked the low profile look of the computers. Was able to talk the seller down due to obvious battery corrosion... and wow no kidding; the old Ni-Cad battery had eaten away parts of the PS/2 circuit, specifically for the keyboard. Amazingly other than...

Got a IBM 5151 that I've been trying to figure out. The CRT has power, but no video shows up on the screen (setting the brightness to max shows raster lines). Tried replacing the 7406 chip. Checked the contrast pot and it goes from 0ohms to 500ohms Checked against a IBM 5150 first (MDA and...

Here are two pictures of the drive: http://imgur.com/a/OCzlU I am selling it $400 (or best offer), half the price of what most of them are going for ($700-$900). The floppy drive powers on, but I don't have the means to test it currently. Due to the age of the hardware, selling as-is. It...

Some of you may remember a while back I was interested in a PDP 11. Almost got a 11/34 but the guy scrapped it before I could get it. While browsing ebay, I so happened to find a 11/04 with 4h remaining. Sniped it at the end (sorry to the two other bidders who were fighting each other) and won...

Earlier I talked about my interest in the PDP11. I got a few cards for the CPU cabinet (still need a lot more) but I am having trouble figuring out which backplane I need. The installation manual mentions part 7011051 Rev D for the KB-11 C Processor. Is this the part I am looking for? Do they go...

This ebay account annoys me when I am searching for vintage computers. Recently I have been looking for a 5150, and this guy has like 8 5150s for $300+, and most are in incomplete condition! Example (5160)...

I read today that plugging a 5151 into a CGA Card will fry the monitor. Is this true? If it is, I am lucky because I probably would have done so not knowing. I also have a Commodore PC10. Is the 5151 compatible with video out on that machine? When I bought the PC10, it was had a photo of it...

As the title says, looking for the manuals and the system disks (the ones that control various hardware).

Got a PC10 recently with keyboard, in great condition other then a few dirty marks. However it did not come with a monitor. What monitor did the PC10 use? Also was the DOS used for it their own variant, or MS-DOS? Which Version? Going to post this in Marketplace but anyone have the manuals and...

Hello everyone, been looking into older pre-PC computers, and getting really interested. I love programming older vintage computers (why I collect them), and have been playing around with a Altair 8800 simulator. However after watching this video: http://www.youtube.com/watch?v=XV-7J5y1TQc I...

Anyone selling the GTO for the IBM portable? Looking for both binder and the holder it goes in. Also the PC-DOS 2.10 disk.

So was at my local thrift store and found a IBM 5152 printer. Thought, hey it sounds like something for the 5150 and grabbed it. They made me pay for the freaking cable extra! *Shakes fist*. Anyway went by a Staples Depot, grabbed some dot matrix paper, and headed home. First thing it does is...

I am in search for a very specific motherboard. I want to repair my old dos pc I had since I was little, broken when I fried the motherboard (don't ask how). It has to be the right one because, well it has a lot of nostalgia behind it. I remember the following about the mobo: -Was a PCChips...
