Wow! I can't believe I got recommended this video. I'm the guy who sold you this computer. I put in the empty disk drive so you could put a gotek in there and make it look original. I put in that original single sided disk drive. That drive was kind of limiting for me. You really need at least the 360k drive. I put this computer together with all the left over parts I had laying around after I restored my IBM 5150 to mint condition. I know it's been a while, but I hope you still have it. If not, it's all good. Just as long as it went to a good home. I tried to get rid of all that rust using that fall out remover for car wheels, which I learned from Adrian's Digital Basement. I also put in the beefier PSU so if you wanted to put in the MFM drive you could. Probably better to go with XT-IDE though. If you need more parts, let me know.
I think it's not a CGA, but an MDA card. The CGA cards usually didn't have a parallel port, but instead of that a composite output. The 9-pin sub-d connectors were all the same for MDA/Hercules, CGA and EGA cards and monitors. The WD card is an old MFM hard drive controller card. But not the original by IBM, since they were limited to only a few types of hard drives, depending on their revision. You had the CPU already on video, it's the large chip next to the keyboard connector.
I didn’t realize AMD made an 8088 in 1982. My 5150 has an intel 8088 that says ‘78, ‘81. And there’s an 8087 (math coprocessor) that says ‘80, ‘81 but has “IBM” stamped on it as well. Someone gave me an NEC V20 (I think) at some point to swap out the CPU for a slightly more efficient one, but I swapped the original chip back in for authenticity. (But now I have a VGA card in it because I don’t have a CGA monitor, so anyway…) The long beep and 2 short beeps are because the dip switches are set wrong for the video card you have in it. Look for a PDF of the “Guide to Operations” manual. I still have the manual which comes in handy. But it works anyway so it barely matters besides the beeps. Or look for a web page that documents the dip switches. The basic you boot into off of ROM when you don’t have any disks is cassette basic. Meaning when you save or load it uses the cassette port. I doubt anyone really used it and it was dropped from future computers.

:) I still have it. It's in my collection. I'll have to make another video with it.

Thanks David! I appreciate the comment. I eventually made all the discoveries you mentioned once I put the camera down and took a closer look. :)
