+sixersfan105 Posted October 25, 2019 Share Posted October 25, 2019 So I've got a "new to me" TI-99/4A computer scheduled to arrive on my doorstep tomorrow, purchased through Facebook Marketplace; I'm very excited! This will be my first TI computer. It's been successfully power tested (red light comes on) but is otherwise untested for functionality due to the owner being unable to hook it up to his modern TV. Fingers crossed it works. I've read through the "New to the Group" thread and it's been extremely helpful. Thought I would list everything that my incoming bundle comes with, along with everything I've purchased over the past few days in anticipation of its arrival, and you all could let me know if I'm missing any must-haves, in terms of hardware add-ons, accessories and games. I attached some pictures of the bundle, too - it comes in a nifty carrying case/suitcase seemingly designed for it! Part of Bundle: TI-99/4A Computer (Black and Silver version) Two original joysticks Power Supply RF Modulator Speech Synthesizer Early Learning Fun Addition and Subtraction 1 A-MAZE-ING The Attack Beginning Grammar Munch Man Parsec Blasto Hunt the Wumpus 2 Teach Yourself BASIC audio cassettes Manuals and reference guides for most of the above Items Purchased in Anticipation: TI-99/4a to Atari 2600 Joystick Adapter (by TexElec) TI 99/4A 32K Sidecar Memory Expansion Card with 3d-printed Case (by COREi64) NTSC Composite Video Cable (from Arcade Shopper) Borzork (from Arcade Shopper) Power Supply for 32K Sidecar - when used in conjunction with speech synthesizer (from Arcade Shopper) Burgertime Moon Mine Chisholm Trail Car Wars Tombstone City I suppose in time I should consider purchasing an SD cart so I can easily play homebrew ROMs. Beyond that, any other original games you recommend I purchase, and/or hardware add-ons or accessories that are must-haves? Thanks for any and all insight! 5 Quote Link to comment Share on other sites More sharing options...
pixelpedant Posted October 25, 2019 Share Posted October 25, 2019 A FinalGROM (flash cart) would definitely be the next thing. Original era first party TI-99/4A carts are really not the bulk of the TI-99/4A experience, at this point in history. So much of the very best of development for the system is found in all that came afterward and elsewhere. And to that extent, a flashcart that gives you access to almost all of that is key. 2 Quote Link to comment Share on other sites More sharing options...
jrhodes Posted October 25, 2019 Share Posted October 25, 2019 (edited) Perhaps down the road, as you dive more into the TI, you may consider a TIPI (TI to Raspberry Pi connection), which will basically allow you to have a virtual disk system. Very neat looking case, i like that. Edited October 25, 2019 by jrhodes 1 Quote Link to comment Share on other sites More sharing options...
cbmeeks Posted October 25, 2019 Share Posted October 25, 2019 That case is killer! Welcome to the TI...stay a while....stay FOREVER! Oh crap...wrong platform. lol Seriously, the TI scene is very vibrant. I also recommend putting your name on the MK2 list for when it's ready. Having a sharp VGA signal for the TI is amazing. 1 Quote Link to comment Share on other sites More sharing options...

Your interpretation of that page is different from mine, but instead of guessing we should ask @matthew180.

+sixersfan105 Posted October 29, 2019 Author Share Posted October 29, 2019 Random q: does it matter if the computer is on or off before putting in a game cartridge? Some game manuals specify that the computer should already be on before putting in the cart, while others state to insert the cartridge and then turn on the computer. What gives?

Casey Posted October 29, 2019 Share Posted October 29, 2019 Generally, it does not matter if the computer is on when you insert a cartridge. The cartridges will almost (but not always) cause the computer to automatically reset to the title screen when you plug it in. There are a couple of exceptions. Mini Memory is a battery backed cartridge that contains some RAM that you can store programs in. It definitely does not like to have the computer on when you plug it in. I also would not do that with a FinalGROM99 cartridge if you get one, since it has a rewriteable ROM in it. Better to be safe than sorry. Most of the manuals also tell you to remove the cartridge while the computer is on, after returning to the title screen. My experience is that sometimes works ok, but sometimes locks the computer up. All that being said, I have never damaged a console or a cartridge by removing it or inserting it while the computer is on. Take that with a grain of salt.

+adamantyr Posted October 29, 2019 Share Posted October 29, 2019 I usually yank cartridges out and if the computer goes all "YAAAAH!!!" on me I just turn it off and on again. 2 1 Quote Link to comment Share on other sites More sharing options...

JB Posted October 30, 2019 Share Posted October 30, 2019 I've long turned the system off to change cartridges. You're SUPPOSED to be able to hotswap them(which would make the Disk Manager\Extended Basic\Editor/Assembler shuffle less annoying), but it seems highly dubious in practice. 1 Quote Link to comment Share on other sites More sharing options...

Ha! I do plan on getting a FinalGROM soon (already got a case for it) but I primarily intend to use that for the super hard to find and homebrew games. I love physical cartridges, what can I say? 1 Quote Link to comment Share on other sites More sharing options...

I just picked up a huge lot of TI stuff, which includes a ton of cartridges. What games do you already have? I see your list on the first post of what cartridges you have and are getting... Here's what I have that wasn't on your list: Hangman TI Invaders Blackjack and Poker Yahtzee Sneggit Football Indoor Soccer Tunnels of Doom (cart only) Adventure (cart only) Protector Pacman Jungle Hunt Centipede Popeye Edited October 30, 2019 by adamantyr Adding details 1 Quote Link to comment Share on other sites More sharing options...

+sixersfan105 Posted November 1, 2019 Author Share Posted November 1, 2019 Thought I'd add that the Paez3D case/shell for @TexElec's stellar TI-99/4A to Atari Joystick Adapter is fantastic! Paez3D is always able to make more if you don't see any at any given time on his eBay store. Having that adapter sit flush against the side of the computer is so much better than an annoying dongle imo. In terms of the Adapter board itself, you can save a dollar and sales tax if you purchase directly through TexElec's website. Quote Link to comment Share on other sites More sharing options...
+Ksarul Posted November 9, 2019 Share Posted November 9, 2019 One note on cartridge insertion under power: cartridges from TI generally have the reset circuit, as already noted, but that protection isn't perfect. GROM only cartridges generally have no issues with removal under power, but once you add ROMs to that mix, it becomes a bit more problematic (as Tursi noted). That said, with third party TI cartridges, insertion/removal under power is not advised, as most of them are ROM only and may or may not have the reset circuit present. I just turn power off for every change of modules, as that keeps it to a single process safe for all of my cartridges (and I do have a lot of them). 1 1 Quote Link to comment Share on other sites More sharing options...
+mizapf Posted November 9, 2019 Share Posted November 9, 2019 (edited) A "reset circuit" in a cartridge is new to me. As far as I know, the cartridge port produces a reset by connecting the reset pin to ground (permanently), i.e. when you plug in a cartridge, you short-circuit the reset line with ground. This signal is fed into a capacitor/resistor setup, leading to a short pull down of pin 5 of the TIM9904, which produces a RESET out signal for the CPU and other circuits. See console schematics, C506 (22 µF) and R514 (47K) connected in parallel, located left from the CPU. When the cartridge is removed, the capacitor is discharged via R514; then you can plug in the next cartridge.
