Sorry took so long to reply to the thread @nanochess. I actually had to go one step further in fixing mine. Just got it all working again today. To install the kernel.dat file I had to download & flash an SD image to a SD card using this: SD card image for recovery Then I was able to flash kernel.dat, then I could use OPFXSD to install dskrom.rom & romdisk.dsk. Can finally load roms & desks again! I think the SD card image for recovery gives you a FAT12 formatted card pretty much which allows you to install all the software you need if in my situation. If you Google flashing SD image to SD card there are tons of wikis Todo it. I followed one for a Chromebook. Worked great! Thanks for your help btw, this was a tricky one! cheers Daryn

Hi I had purchased the Megaflashrom for my SVI-738 (MSX1) few years ago. Hadn't used it in a while, then the other day stupidly deleted the kernel from the recovery menu and the romdisk. So now I can't run OPFXSD, call fdisk erc etc. Get no A: on bootup of the megaflashrom in MSX Basic. Thought no problem, I remember there being a way to recover the kernel. This site does a good job at describing process https://blog.falvarez.es/2013/04/megaflashrom-scc-sd-tutorial.html Essentially with a blank microsd card, you copy the kernel.dat file to it, jump into recovery mode on the megaflashrom, choose "F4 - Install microsd kernel" & it should work. With me I run that, it scans the card fine, eventually finds the kernel file, but when installing it gets an error "kernel too big". Have tried multiple sized cards, even used archive.org to find an older version of the kernel.dat file. Nothing works. Always get "kernel too big". Does anyone know what I need to Todo here? cheers Daryn

Is it time for another Wikipedia update?
palmheads replied to Omega-TI's topic in TI-99/4A Computers
Yeah its strange huh? It was like the inference was I was trying to drive traffic to my own website with content (as if it would actually do that!?). But ignored the fact I was bothered enough todo my own research, found a relevent source (not mine, an actual offically branded players card), and was trying to provide proof that the info I was updating had some validity to it. Not sure what else someone could do for something so minor as a players height/weight info! haha -

palmheads replied to Omega-TI's topic in TI-99/4A Computers
Yeah updating wikipedia can be a pain. Few years ago I updated some height/weight details of a Rugby player (I had a breakfast cereal players card with his details on it). I had scanned the card in and uploaded to my website, so I could use it as a reference on the wikipedia article (was trying todo the right thing not updating stuff without some sort of proof). Because the domain of my email address matched the domain of my website, the update was rejected (something like self promotion). I think I got around it by using a different email. Just sometimes lacks common sense. -
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.

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 -

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
