Hey Folks,

New here, so I apologise if I'm off base at all.

I have some hardware questions, but first a little background :-)
I'm a "general" collector of 8 and 16 bit retro systems, triggered by a friend of mine giving me an Amiga CD32 about 8 years back. (Up until then, I'd been a fan of retro emulation). I'd been slowly growing my collection of "core" systems to cover the majority of 8 and 16 bit systems to the point where I was really only missing two main systems, that being the TRS-80 Model 1 and the TI-99/4A.
Then the past weekend, while going through, cleaning up a "trashpile" of old systems, I managed to find a Dick Smith System 80, which is a clone of the TRS-80 Model 1, as well as a pair of TI-99/4As! (One beige and one silver)
So now I have a collection that spans the majority of mainstream 8 and 16 bit systems :-)
(I have [deep breath], an Acorn BBC Micro B, BBC Master, Master Compact, Electron and Archimedes 440, an Amstrad CPC 464, an Apple 2 europlus, 2e, 2gs, Mac se/30 and Quadra 950, an Applied Technology Microbee 16, Microbee PC85, Microbee 128k and Microbee 128k premium, An Atari 800xl, STfm and STe, A Commodore PET 4032, VIC 20, C64, 128D, Amiga 1000, 500, 600, 1200 and 2000, Sinclair Spectrum 48k, Tandy Color Computer 2, VTech CreatiVision and a clone MSX 2 I assembled myself  :-) )

Back to the TI-99/4A, neither system came with modulator or power supply. 
I've been looking into my options for getting power in and picture out, but until I know the units are actually working, I don't want to put too much money into them. I'm also in Australia (PAL region) so ordering stuff from Ebay tends to mean I pay twice what the goods are worth in shipping, so DIY is my preferred option.

On the power front, I was thinking of getting a suitable MeanWell and use it to bypass the internal regulator entirely... It'll work in my initial testing. The other alternative I have is I can get a transformer locally that's rated for 2A that has a 18V outer and 9V center tap I could possibly use? Is the extra 0.5v on the smaller winding going to be an issue?

On the video front, well, that's more of an issue. I know PAL units do a "component" out. What are the chances I can feed that (Possibly with suitable resistors) into a Component capable monitor? (I have an old LCD TV I use for a lot of my systems)

Anyway, great to enter the 99er club, even if my systems don't yet work :-)

Cheers!

John

  Realms of Antiquity Collector's Edition
Posted by: adamantyr - 08-22-2021, 01:35 PM - Forum: Software - Replies (2)

Hi all,

In December of 2020, I released Realms of Antiquity for the TI-99/4a through ArcadeShopper's storefront, and a few months later, on the Steam and Itch.IO platforms.

I also marketed a collector's edition which included the game ready to play on hardware. I currently have a Kickstarter running to produce another run of collector's editions, and I want to make certain no 99'er misses out on it.

https://www.kickstarter.com/projects/arc...rs-edition

Please note the system requirements: you need a SAMS to play the game, either a side car or a PEB card will do. These can be purchased through ArcadeShopper.

8 days to go, and currently 59% funded!

Thanks,
Adam

  Playing Popeye & Games List
Posted by: jonesypeter - 07-14-2020, 03:56 PM - Forum: Software - Replies (2)

Hello,

I'm new to the TI99/4A.  My home computer as a child was the ZX-Spectrum.

Couple of questions if I may:

Is there a site which shows screenshots of TI Games?  Rather like Lemon64 or similar?

I'm trying to play Popeye via Classic 99.  I have downloaded the TOSEC archive from archive.org and there is a part one file and a part two file.


Popeye (1984)(Parker Brothers)(Part 1 of 2).g
Popeye (1984)(Parker Brothers)(Part 2 of 2).c

Finally.  How do I report spam?  The report button under posts does not seem to be working.

Many thanks

  Problem with Cartridge Image not fitting on TV screen
Posted by: JStoller - 05-24-2020, 11:49 AM - Forum: Software - No Replies

I was finally able to hook up my TI 99/4A to a new flat screen TV, but some of the images from math games like Alien Addition don't fit perfectly on the TV screen (e.g., one equation only shows partially on the left side of the TV screen).  Any advice on how to correct?

  Viditel / Presetel prototype cartridge
Posted by: hofster - 04-13-2020, 03:26 PM - Forum: Software - No Replies

Hi,

I found a prototype cartridge for the TI-99.
The cartridge is labelled Viditel although it has programs called Prestel and Bildshirmtext on it too (same thing in different languages perhaps).

[Image: 1108x500-1.jpg]

I wonder if anyone has any more knowledge about this little gem.

I posted my findings here:

  Plato - Bad Chemistry Disks
Posted by: GullibleRaspberry9 - 11-25-2019, 12:11 AM - Forum: Software - No Replies

I have been going through the Plato High School Science - Chemistry course with my son, be we are hitting some bad disks.  

I have both the Mess emulator and the v9t9 emulator able to run the Plato Rom with the TIDisks downloaded from either whtech ftp or 99er download database.

I have never had any issues running any of the disks for many different subjects: High School writing, math, biology, physics.   However, in the Chemistry subject disks: 7, 9, 10, 12, 14 all load, get past the Plato welcome screen and to the course Menu screen.  It will say for example, "Menu 1. Chemical Reactions 1 Tutorial 2. Additional Studies 3. Select another Diskette.

When I choose 1 for the tutorial,  the disk starts reading but then just freezes.  The screen doesn't change, and the white message on the bottom just says: "Type the number of the" . 

I am hoping someone has any idea to help us along so we can finish this great course for Chemistry.  My son loves this style of learning.

Thank you for any suggestions
