Mike's PCjr Page

I have a Gotek that I flashed with HXC and it works great on the PCjr. The PCjr read/writes both 360k and 720k disk images with no issues. I added an OLED screen that is much better than the stock LED display.

Ok I was able to combine the files to one ROM image and it works! I tried the files in different orders and it seem to work about the same no matter which order the files are arranged. Some differences I noticed from my Combo Cart 2 is that the Combo Cart 3 does not have the Quicksilver (fast boot) ...

That's great! Can you post the combined files image? Thanks

I came to the same conclusions on the other files... Hmm now I'm thinking my next project is to build a Combo Cart 3.

Glad to hear it worked out for you!

I made another to factory specs and now have two! As you see in the picture, my wife got creative with the second label on the white 3D printed shell

The 27C256 chip should work. I've attached the ROM image of my cart that works perfect for me... no header, just burn it to a 32k chip. Looking at the Raphnet PCB, it appears you need to set jumpers J8, J10, and J12 for cartridge select line 2 (CS2). Hope this helps!

I used a 28C256 RW EPROM with the other cartridge PCB currently available. I have it set to CS5 but after reading the manual I now see that conflicts with Cartridge Basic. The original factory cartridge was set to CS2, but I think I'm going to leave mine as is ... will I ever have a reason to use bo...

Here is the final product. I'm happy with the results and it will be a nice addition to my collection. Reading the manual, I'm surprised how much this cart does ... including allowing DOS 5 to boot without being patched! Thank you Kablamabam for the image! http://www.jscrowley.com/images/compcart2.j...

Success! The D800.BIN file is the Compatibility Cartridge image. Once I figured out that I needed to remove the header that PCJRCART adds to the file, I was able to successfully burn to an EPROM! The new cartridge works perfect and jrCONFIG no longer displays Compatibility Cartridge not found :D htt...

Awesome! Thank you!

I have the Combo Cart 2 which doesn't have the compatibility cartridge. I'll run PCJRCART on it to see what's different and post an update ...
