Last couple of days on a New Zealand Vintage Computing Group Facebook page we've been talking about the TI-99/4a. One of the guys had this great story where he recounted to us ... found the original 2011 message https://www.classic-computers.org.nz/forums/viewtopic.php?f=11&t=505 Basically a Research Vessel called the "Tangaroa" for one of our Science Research Institutes (NIWA) had a broke comms system back in 2011. The CPU in the comms system was a TMS9900! It needed to be fixed urgently, and would have taken too long to get a replacement chip into NZ, so the guy repairing it found a collector here in NZ, and this guy had a non working TI-99/4a so he donated the motherboard to get the comms system fixed!

"decommissioned in 2022 in the UK after 37 years of 24/7 service" Wow! -
Hey guys I remember @rasmus saying once for a port of a Z80 game for the TI, he really needs Z80 source code. So here is an intriguing possibility! https://github.com/santiontanon/transballmsx Its a "Thrust" like game for the MSX with full source. Same graphics chip as well. Looks a great game! You can play it online here: https://homebrew.file-hunter.com/index.php?id=transball Anyway, another game to add to the list of possible ports for the TI! cheers Daryn

Has the COVID-19 hysteria increased your TI-99/4A time?
palmheads replied to Omega-TI's topic in TI-99/4A Computers
Working from home last 2 weeks, New Zealand about to go into full lockdown w/state of emergency as of 11:59pm tonight for 30 days. Am actually finding am working longer as people with flexible hours now have different work schedules. I did look at my xdt99 config for my "Thrust" game code couple of days ago, so fingers croseed -
Probably not exactly what you want, but there is that Miniwriter word processor that ran on the mini memory module.

Learning assembly - porting Thrust to the TI-99/4a

We find out this week how long they want to keep us. Won't say much more until after gone. But yeah, I think feelings are rather obvious. Ugh. cheers Dazza -

Hobbies are a great distraction! Good luck, hopefully you can find a role that makes you happy & gives you enough moola! -

Hi guys Done nothing in a while I'm afraid.

Game idea: Port of ZX81 game "City Patrol"
palmheads replied to palmheads's topic in TI-99/4A Computers
Oh wow that is slow. Graphically it does look doable though! Could be an XB/Assembly job then -
Hey Whenever I'm mucking around with my other retro computers, if I see a game they could be cool on the TI-99 for TI-BASIC & mini memory (perhaps for next 4k challenge) I make a note of it. Been playing this game on my ZX81 (real & emulated). http://www.zx81stuff.org.uk/zx81/tape/CityPatrol You are a turret that turns 360 degrees. In front of you is a city scape. The city is in layers - some buildings closer, some further away. You have a gun sight. UFO's fly up/down/between buildings. You have to aim with your sight & shoot them. You can blow up buildings but you lose points. The UFO is also shooting at you (quite effective - a white square with an asterisks when it shoots. Its really playable & enjoyable! cheers Daryn

TI-99/4A Stuff - The "what I'm looking to buy" topic.
palmheads replied to Omega-TI's topic in TI-99/4A Computers
Gotta learn howto build stuff like that first! From my limited knowledge, it does look relatively simple. -
When you look at the quality of some of these games, if only TI had introduced the mini memory module maybe 6 months earlier than they did. You would have seen a bunch of impressive games on cassette for the console only. Only a handful were actually developed. These games are fantastic

Oh wow thats fantastic Bones-69!!! Thanks awesome feedback from Jeff Minter himself!! And Mr Minter - love Gridrunner on Android! Also love opening up a Vic 20 emulator and playing Matrix. That PS4 version looks great! -
DS990 Commercial Computer System - anyone has experience?
palmheads replied to kl99's topic in TI-99/4A Computers
Interesting too see doco relating to converting the Model 770/771 terminal (used as terminals for the /4, /10, /12 etc) to a DS990/1. http://www.bitsavers.org/pdf/ti/990/ds990/2262327-9701_Model_771_Intelligent_Data_Terminal_Upgrade_Instructions_to_DS990_System_Model_1.pdf
