Re: The VIC 20 is brilliant thread

I'm loving my Vic-20 today because it's the only area of my computing life where I don't have to worry about meltdown and spectre. The 6502 is definitely not vulnerable!

None, I just used the file created by norm8332 from this thread:

I uploaded the file to DirtyPCBs, and voilà, the above appeared in my mailbox.

Ugly video output

Bought a vga converter to connect my Vic to an LCD monitor. It looks terrible.

I adjusted the pot according to the wiki (this is a cost-reduced Vic so only one pot) and it makes it brighter but that's it.

Is it because my vga converter is crappy?

My PCBs are here!

So, these arrived today:

For most of the people that hang out here this is old hat, but I've never done anything like this before. I've hardly ever soldered. :shock:

To me, these things look beautiful! Creating a Vic-20 cart is kind of a bucket list thing.

Re: Node MCU

I've been playing around with connecting a NodeMCU to the Vic-20 userport serial interface and building various TCP and/or HTTP clients and servers with micropython. I was thinking how cool it would be to use the ESP8266 as a serial to UDP converter for multi-user games. I've seen threads on other f...

Testing serial port code on a Mac with VICE and a local terminal

I'm working on learning ASM serial communications and I need a convenient way to test from VICE 3.1 running in my Mac OS X Sierra environment. I came up with this method which lets programs running in VICE talk to a terminal without actually having a terminal plugged in via USB, or using VMs or what...

I'm getting them from eslapion but he doesn't have any capacitors.

How do these look?

Re: Cartridge designs released - Eagle PCBs

Okay, I just ordered up a protopack of boards. I think I will get a few sockets and make a couple dev boards for testing the eproms. If anyone has a link to a socket they would recommend please post it.

Re: Cartridge designs released - Eagle PCBs

Is the idea to solder something like this to the board: https://www.ebay.com/itm/28-Pin-DIP-Machine-Pin-Socket-Lot-of-3-628MP-/162065002326?hash=item25bbd3af56 and then plug the eprom into it, or just to solder the eprom directly to the board? I'm thinking to fit it in one of those beautiful cases t...

Re: VIC cartridge PCB eagle

This is an area I really want to learn about. Once one has a board like this, what's the overview on moving forward? I'm a noob with electronics but I'm thinking you get the board and then you have to find the components needed (dip socket, any switches, resistors and such) and then solder it all up...
