The terminals (the thermal ones) simply dialed each other over a Viking dial simulator and made a 300 baud connection. Next year, it’ll just be phones, Pyuuta, and 99/4. Two tables…. 🙂 By the way, we made it in a DragonCon video too!

DiskAssembler also used the same type of protection.

@FALCOR4 is in this very forum 🙂

Ooh.... will he be there again next year? If so, I'm dragging my cart there.

In my binder right now, I have: Vol One (only four pages from what was linked) Free Mini Sample Feb 1984 - Sep 1984 (doesn't say Vol anything) June 1986 - Feb 1987 (Vol 2)

Great, thanks! So this goes before the Feb 1984 edition as well as the free mini sample.

Yep, the dates are on their website for next year. July 19-21 2024. I don’t know when they’ll open the hotel block again but I want to reserve as soon as they do.

There’s also UberGROM binaries that I made too from the GROM disk images that are in the UberGROM thread if you want to make your own carts

Also makes me wonder - if he wants to SMT mount, and use 3.3V, and level shifters, how many lines total do we need to level shift here? - A3 to A15 (13 pins) - D0 to D7 (8 pins) - ROMG* (ROM access - 1 pin) - WE* (bank switching - 1 pin) - RESET (Do we need to level shift this for balancing things? Or since it's "outside" in the 5V realm, are we ok?) - VCC (I'm guessing this is a 3.3V regulator and not a level shifter with GND) Rough guessing - 13 + 8 + 1 + 1 = 23 pins need to be level shifted if the SMT device isn't 5V tolerant. Or, find an IC that might be out of spec tolerant like a lot of those reproduction carts that Aliexpress seems to sell for Nintendo systems which don't even use level shifters (and use 3.3V EEPROMs.) TXB0108 is an 8 bit 3.3V to 5V level shifter (you'd need three of them). I wonder if there's a larger one (maybe a 16 bit one plus a TXB0108? or a 24 bit one?) I think I remember talking about that with either you or @Ksarul a long while back when we were discussing a SMT 512K board or SMT UberGROM. It definitely would make the price go down, but we would have to get someone who could do SMT to either build them or get a bunch made by someone.

If you make a SMD version of the cart, please let me know - I'd love to have one. I've been collecting all the variants since I made the original ones just to appreciate the diversity in innovation. It's pretty darn awesome. Plus, I know how difficult SMD is, and appreciate the work going into it, so I'd love to see a board version as SMD. (BTW, are there parallel SMD 5V 27/28C040s or something equivalent?)

I was right next to Alan. Just so much to do there - next year, I think it'll be cut down to just two phones, the Tutor, and the TI-99/4 choo choo train. If I cut down to two phones (two lines), I probably can get it on two tables, which is a bit more manageable than the four that I had this year. A lot less stressful too. (@Ksarul, I might want to borrow your sidecar p-code and video controllers next year if you're amenable... I lost count of the people asking me why I didn't have those to show if they made them... LOL) @OLD CS1 traded me an external drive (without PSU) to see if I could get one external drive working for the stack. Live and learn... kids love to interrupt the "dial up" connection between the TI Silent 700 thermal printers and put it in perpetual barber pole test print mode (wasting paper) somehow, you put a two trunks on four phones, you get people stepping on each other dialing, people were more interested in my beige IBM keyboards on the dumb VGA terminals than playing with the terminals, the TI-99/4 FinalGROM didn't work because it didn't recognize keypresses, people don't like hard video games on the Pyuuta, etc... and four tables is way too much for either the wife or I to keep up with. Popularity? #1 - Interactive Bell Western Electric Phone 1A2 exhibit (dial in/out) - by far #2 - TI-99/4 #3 - Pyuuta #4 - Thermal terminals #5 - CC-40 and 99/2 (only one person was interested) #6 - VGA interactive terminals I'll likely be selling the Silent 700's for what I put into them (plus the materials) plus s/h since I won't be exhibiting them. I have the 300 baud dialup one, and the 1200 baud version. I also have a "dialup simulator" box by Viking to hook them together. Both have a case - one is a TI case and one is a generic "terminal case" that is green.

That was pretty darn awesome, too. So was the girl that completed Dragon's Lair!

Yep, too much going on getting ready for VCF-SE It was a blast this past weekend, BTW. Regardless, I opened an issue on Git. So, I'll be really curious if he actually sees it... "Hm... five years, and this hexbus guy opens up an issue about a 99/4...." 🤣

Is that official? I didn’t see it on the Git repo.

Just FYI (and don't think anyone's tried this yet), but my FinalGROM at v1.3 (latest) does boot on a TI-99/4, but the keyscan routine keeps it from actually being used on the 99/4. It just sits at the root directory. I opened an issue on the FinalGROM git about it. @OLD CS1 you can blame for this one. He asked me if it worked on it since I'm setup right next to him.

The DSR he provided is right here:

Yep, great spelling game for the kids! This is the 16K cart I actually used back in the day (along with Carlos’ 8K one) as a template to create the first 16K Guidry cart board many moons ago! Has a 16K eprom and 74Ls379 in it 🙂

Yep, those are all out of scope. And ROM carts, too, because it won't read the ROM header. The keymap ones.... there has to be some easy fix (hexedit) to the key scan routine to get those to work on the /4. Otherwise, they don't use bitmap nor are they ROM-only, so that's the only thing keeping them from working. I have the local group's monitor guy looking at the monitor. It's on the 75 ohm setting right now - if I switch it to the other setting, it gets bright and loses focus. I'll see if he can fix it or not. If not, I have a nice 13" Trinitron monitor, but it won't be the TI one. Still looking for these two things to help with the exhibit (for anyone else reading): Another TI external floppy drive. (And yeah, I know the terminators are needed on these drives... last one in the chain.) TI Impact printer (complete with serial) and/or just the serial card.

Gradually working on my 99/4 system and finding quirks along the way that I need to figure out or just work around. Thanks to the fun ride that is my health, I have some great folks helping me load and setup this year - since I can’t handle much exertion/lifting right now. https://vcfed.org/events/otherevents/vintage-computer-festival-southeast/ I’ve tested all except the disk system and the modem so far (it does make test noises), and so far, so good. Editor assembler can see the memory expansion. Basic can talk to the RS232. A-maze-ing can print mazes to the thermal printer. I’ve noticed some strangeness on some of our GROM carts. Break free and XB 2.7 won’t let me press a key. I can’t do anything 😂 but they should otherwise work. Key scan issue? Would this be easy to patch for the /4? Alpiner immediately goes past the title screen and then doesn’t use speech like it’s supposed to. Speech editor, XB, and Division 1 all work ok with speech. My monitor is a bit dim. This is on full brightness and contrast. I’m going to see if the resident monitor expert can look at it. Else, a Trinitron will be there. Disk access is next. I know I need to probably clean the drive and will likely go thru a couple of disks. If anyone has any of the following for sale or trade for a decent price (or will loan to me), it would be nice to add to my exhibit - Serial card for TI Impact printer to I can hook it up to the RS232 (or whole printer for decent price) Additional SSSD external drive Thanks!

Thank you! I’m excited finally to get one; it makes the whole experience much more seamless. I never had the opportunity back in the day to run these back to back. One person in our group did modify the bank switching method to run in a “write to rom” bank switched Guidry cart, so we have had that for a year or two, but it’s nice to have the original cart with the CRU bank switching routine.

Thank you! I've been collecting them probably since high school. I finally got ahold of the Stargazer I/II/III combo cart (I traded another DBT game, Dragonflyer, for it.) I have most of the John Phillips carts that I had his source code for (I'm the one responsible for getting that out into the community long time ago), and Stargazer I/II/III completes it. (It's a 32K CRU based cart with a PAL for bank switching, like SuperSpace or TI Workshop.) I have another drawer of carts with more DBT carts above that drawer, but nowadays, most of my usage is via the FinalGROM, so I rarely take them out.
