seemed impressive!

I have a 1200XL, I want a hard disk solution that leaves the cartridge port open. U1M with built in SDX is awesome, but I want to use BXE, in extended mode. A soft loaded BXE is not gonna work with an SIDEx in the cart port. An under Sally or under ANTIC HD adapter thing would be nice for us who don't have a PBI.

Would love to see this fished someday with support for Bit3 card and xep80.

What a cool setup - thanks for showing the comparison to stock video.

thanks for the update mate. Good to see this. I got 6 ataris, haven't done anything to them yet - but s-video mod. So nice to see options.

You left the green wire insulation bits inside (when you stripped the ground wire) :)

Would the GTIAdigitizer work on the 600xl?

Could you tell us later how you would have proceeded with the addition of sound?

Do you have a link to the RGB2HDMI device?

I've got the GTIAdigitizer in my 800XL and a VICdigitizer in my C64S. The image from the RGB2HDMI is pretty blooming good but I'm working on a method of injecting audio also. If I get it to work I'll give you a shout. Keep checking the firmware updates on GitHub for the PiZero in the RGB2HDMI.

Wow!

You look fantastic. Mine is on the ring finger. I wore it for 60 days (February and March 2024), and the doctor informed me I didn't need the splint and that I should see hand therapy after 1 month. I went to hand therapy last week May 15, 2024 and they said my finger became worse with a 35-degree drooping swan neck deformity, so they prepared a custom splint mold. They told me to wear it for additional eight weeks😥. I went back to the doctor today 5/20/24, and I'm not sure why they took off the splint and ask me to make a fist, because aren't you supposed to wear split religiously and not bend no matter what? Sorry for the rant.

I just got myself a Fujinet and…. A SIDE3! Can’t wait to play with that. Thanks for your great work!

Hi FJC - Thanks for all your great videos and and awesome knowledge and advice - Do you know when I could order the replacement Delay Line kit that you mentioned? I've seen the GitHub link but I don.t think I can order from there? I've got an 800XL that I'm trying to repair and the Delay Line Chip is my first possibility. If that doesn't fix it then I'll be after a new CPU too. Keep your fingers crossed for me. Thank in advance Jon!

Looks amazing… my u1mb came with graphical os in one slot, but when I ran it, the window just freezes on start. What could happend. I have an 800 XL …

shit ad video

Thank you! Your video saved me having to buy silver paint. I got mine working without it. I found that someone had already attempted the fix, the membrane side of the connector was clean, but they left the tape on the PCB side, They actually painted silver on top of it . All I had to do was remove the tape from the keyboard, clean it up and put it all back together.

On the speech synthesizer, the door does nothing. It was meant to accept new speech ROMS but that never happened. And as for the joysticks...they are quite awful as you will soon discover. LOL

The TI-99/4a was my first computer. I have many of them now and still use them. It really is a strange computer that you either love like me, or hate. lol

There is a fix for that Alpha Lock problem using a diode.

Nice lighting!

Good computer, terrible joysticks. The speech synthesizer needs speech enabled carts or extended basic.

This was a capable and interesting machine, but unfortunately it was never going to work in the UK. We used tape for games in the early days, and typically never bothered to expand our machines. Out of the box, the TI was completely unsuited to games thanks to the machine's inability to run machine code from BASIC, which immediately prevented good quality cassette based games from being available. I thought at first that this might have been my friend's machine from back in the day - as there can't have been many of these in the North East (friend lived, still does, in Sunderland). His dad was a massive Sanyo fan so it surprised me even at the time that he ended up with one of these rather than an MSX!

To delete a character, move the cursor back (fctn key and S key) on top of the character, then press fctn 1 (DEL). Easy when you know how 😅 still not as complex as the spectrum keyboard 😊

The door on the speech synth doesn't serve any function. The original intention was to produce different voice ROMs with male/female voices and different vocabularies etc. but it never came to fruition.

The PAL TI-99/4A outputs YUV from its video connector. Maybe that's why the cable doesn't work?

The RF signal on mine is superb too, actually better than the component using coolnovelties cable (not a dig at coolnovelties, i think the machine is just built that way)

You have to put a chatty dwarf inside the speech synth box to make it work.

Nice work.

My first computer was a TI-99/4A. I loved it. The packaging, manuals and documentation were excellent. And I did use a tape recorder to store programs, but I never got a voice synth.

Of all the computers I own, I have to say that the TI 99/4a has the best video signal of them all in unmodified form. I use a CoolNovelties component cable via an OSSC to HDMI and the image quality is unmatched other than by machines like my 65XE and 800XL that have VBXE's fitted. Weird machine though.

I wonder if rufies can erase the TI's 16k of memory? Bill would know!

A lifelong Atari fan, I always had a fondness for the TI as well. Great keyboard, a very nice built-in BASIC.

Be nice if he would explain up front what the devices are for and which machine they work in, where do they plug in. Lots of acronyms and technical talk but difficult to follow at times.

Looked better as it was

How do get an Atari 800 to display on a modern LCD monitor?

As long as the keyboard switches are somewhat standard that is a super easy fix. It does require de-soldering, but once that’s done it’s a breeze. You can get stiffer higher quality springs that will last almost indefinitely. Or depending on the pin layout you could just out right replace them. Classic style switches are a commodity, and can sometimes be worth something. Edit* After looking up with switches while I believe the springs *could* be replaced, replacing switches is a different story. I’d find it hard to believe there isn’t some way to convert the keyboard to a modern version tbh. That would be interesting.

You'll recover real soon. I had the same thing but the doctor told me I needed surgery. Anyway I just wore a splint instead of going to surgery. Took a year for my finger to fully recover but now I'm able to play guitar again without any problems! I pray your finger will recover soon just like my finger did since it happened on my pinky.

Is Side3 loader cart compatible with an 800XL with the 256k RAMBO XL upgrade?

Hi Is the Sophia 2 the best video upgrade for the 130xe, if anyone can get them

nice work

Just what I want for my 1983 Atari600xl

That came out really well, 600xl is a nice form factor!

Wow, this popped up like it was recommended. Thanks Jon.

8-bit Commodore and Atari computers use Chroma levels of 1Vpp, while the contemporary S-Video standard defines it as 0.3Vpp... that's why the image is so dark.

I like the look of the original 800 or the XE version. Not sure what I dont like about these tho my drive was a 1030 and it was fine.

Jon, are there any signals needed by the U1MB that aren't available on the Parallel bus connector? With the reproduction of the 1090XL I wonder if the U1MB could be moved to a card plugged into the PBI. Or, would the PBI code on the U1MB conflict with the PBI as implemented by the 1090XL?

Extra points for the Star Trek opening.

If it makes you feel any better, practically all one-side-only-ground-vias that I was working on separated eventually ;)
