I cannot plug in this video cable bought from Amazon into my Commodore 64 ... Why won't it fit??? It has the same pin out as the port, but it won't fit? Are the pins on the cable itself too big to fit into the slots on the video port? I need help with this.

After some work, I've created this schematic: System Specs: CPU: Intel 80c188 RAM: 640k SRAM VDP: TMS9918ANL w/ 16k SRAM Hack Keyboard Controller: Intel 8279 Here's a List of my concerns about this schematic and some things I didn't quite understand: the AS6C1008-55PCN 128k SRAM chip has 2...

In my last post, you guys helped me to create a schematic that represents how an 80188 should interface and connect to a TMS9918A VDP. For the last main component of this prototyping project, I need a Keyboard Controller. As I stated before, I'm not going for a DOS Compatible Computer, nor do I...

Here's a schematic I've made for an address decoder for a TMS9918A Video Display Processor. In this Post, I'll go over how this Address Decoder Works . I've based this address decoder off of schematics in the Datasheet (I'll put those schematics at the bottom of this post) for the TMS9918A...

In my last post about my 80188 Prototyping Computer project, I realized I was getting way to ambitious for my project. I'd like to thank the following users who helped me see the errors of my ways: Eudimorphodon (Thx for the sanity check) daver2 Both of these users has given me lots of...

Hello! I need some help. The screenshot below is from a YouTube Tutorial made by Slador. In this chart, when A19 goes low, that represents Addresses 0x7FFFF through 0x00000. However, I'm considering making my own Address Decoder that uses some of the Address Pins. Is there a chart that shows...

(WARNING: LOST OF TEXT AND IMAGES) In my previous post, I learned that if I wanted to make a 16-Bit 80186 CPU Computer, I would've needed 16 bit wide memory and use the HBE pin. So I decided to make a 80188 Prototyping system before making a 16-Bit system. I'll also go over the details of this...

Hello VCF, I need some help with an Intel 80186 Computer project I am designing. A while ago, before my reddit account got suspended, I made This Post on the r/beneater subreddit. A user replied to my post saying "To add 1MB of Memory you need two 8bit 512K chips (lower, upper) and connect them...
