C0pperdragon also has modules for the 2600, Vic20/64, TMS based (CV, TI994A), and Spectrum. I wonder if the TMS version would work (fit) in your CV NUC+.

I recently purchased a few of these USB C to 7pin adapters from @mozzwald and they work great with my XL/XE's. No issues at all running them with Samsung power adapters. https://mozzwald.com/product/atari-8-bit-usb-c-power-adapter/

Retroprinter.com with an RPi converts parallel and sends it to just about any network or usb printer. If Fujinet could send a printed PDF to a SMB share then you could have a script scheduled in Linux or Windows to monitor that folder and print anything that gets dumped into it.

I'm all in for the modern case, but it would sure be cool to have it in a 1450XLD style case. Call it the 1490XLD. There wouldn't be the need for a built-in drive and the height would give room for cards. Making the case would be a challenge though.

I just ordered one. I've been meaning to buy one for a few years and figured this is a good time as any to do so. I'm not as adept with C64 as I am with Atari, but I'm learning.

Let me check tonight if I have an LCD that works with PAL. I've only used this one with a Sony PVM.

Michael, I have a PAL C64 I can lend you if you need it for testing. Just let me know and I'll ship it out this week.

Fortunately, the Atari 8bit community is blessed with a lot of modern options to upgrade. Since you want to explore now, I would recommend a FujiNet device to start off with. There are many servers around the world that you can connect to with FujiNet and boot into games and programs immediately without having to download and copying to an SD card. You'll be able to run the majority of the games with the 800XL's 64K and it will give you time to decide what other upgrades you might want. There are games that do require 128K all the way up to 1MB and like what was mentioned above, you could try those out with the Altirra emulator until you choose a memory upgrade.

Or this in the middle of night:

Hias' MyPicoDos is what you need: https://www.horus.com/~hias/atari/#mypdos

Ha - I thought they were resistors.

You are resisting to ignore.

2 stock 600XLs and a 1088XEL and 3 different GTIAs. It is easy enough to try it in a few more models, but I think I'll get the same results.
