Well at least the Win 11 machine did

When I ran a scan on the download folder only, I do get this warning from Windows Defender. This is the one I downloaded with Firefox at 11:27, on the Win 11 machine. I'm going to bed now but will power on my computers and check again in the morning.

Understood, on the Win 11 machine I just downloaded this page again again, using Firefox and I'm not seeing any virus warnings.

Just tried downloading on Win 11 on a different laptop, Still get a virus warning. This is Chrome on both computers.

Understood. This is windows 10. Just wierd that it starts doing it tonight, haven't had a webpage show a hit since I built this laptop, 6 months ago. I also use Win 11 on my other laptop and I think I'll see if it shows a hit when I attempt to download those pages.

@Albert Seems that at 8:36 my time I had another page here on Atariage that showed the same virus.

Will do, but in this case it seems the site did, for this particular page. I've been downloading these pages since you first brought the Pico Expansion out and have never had a pagr trigger before.

@Albert I got the following warning when I downloaded this page 12 as a HTML Only

Also the dumped code works in Js99er, I tried it last night.

I think it is. This board has to do with video.

Yeh, here's another of a more updated version on that site.

The site linked to is https://www.blunham.com/Radar/Teletext/index.html and has some good info as well as someting that almost resembles a Geneve or TI99/8 motherboard.

On the bottom of the same website is a link more information about the probable indivdual that may have once had possession of this cartridge. On that website it gives the datasheet for then IC you're asking about. The may be some more useful information there too. https://www.blunham.com/Radar/Teletext/PDFs/TMS3556DataSheet.pdf

Here's 6.589 times PI= 20.699953994503147648230357252429 I'm a little older than that. 20.690142601946393649954889238427times PI =65

Interseting back story about it futher down in the comments:

Well 20.690142601946393649954889238427 to be exact

Today's my birthday day. I am about twentyone times PI in age and my belly can be measured in PI 😁

Thanks Jason, I've been busy with Dr's appt. and other workers comp related stuff as well as my wife, but I plan on modifiying at least one shortly.

I will say that I bought 4 teensy 4.0's, which are still in stock and built 4 of the Jedimatt style keyboard adapters. The 4.0's are still in stock. These work well in place of the 3.2 series. same footprint

The MinipPrp TL866 programmers, come with a Windows based programming enviroment. You can pick and choose the devices you are dumping and programming to include whatever GAL chips are in the list. For a Gal, you just need the *.jed file for the programmer, load it in and hit the program button. Now to get to the jed file requires some work, for example dumping the Pal chip for a Geneve VDP, requires a device, like a DuPal decoder, to decode the inputs and outputs of the Pal, then a step to convert that information into an equation that is then converted into a jed file to be programmed into a Gal. That's where I'm stuck at, for the moment as I've been busy with other things and haven't learned that step yet. But if the Jed files are already available like the ones that Fritz442 has posted here on thes forums, then you can burn those easily with a TL866 programmer.

So do I connect 1 wire to the top chip and one to the bottom, or are both wires connected to the top? Can't quite make it out in this photo. Does the firmware need to be updated?

Gals can still be purchased from the electronic outlets, like Mouser, and such, their not dead yet. But the ATF's can be used too. You can still purchase Pal's on Jameco and ebay.

Here's a 3d view of what I've got so far. This is Kicad 8

Is that the Tang 9k? instead of a F18A?
