Tursi Posted March 7, 2021 Share Posted March 7, 2021 1 hour ago, HOME AUTOMATION said: By XMLing out from various addresses, I seem to have localized the trouble to a small section of the GPL code. The issue can be seen, both on screen and in the source code provided by @Ksarul. I didn't give it much thought at first ...but I had noticed early during debugging, that the nuber of players is supposed to display on screen ...yet happens so fast, that it cannot be seen! Looking at the source... e089 08 fmt display the selected key e08a 81 col+ >02 e08b e1 hmove >02, @>8301 e08c 01 e08d fb fend HMOVE is not a valid OPCODE, FMT or otherwise... You can see in my disassembly that the actual used opcode does disassemble to hmove, why do you say it's not valid? The opcode is handled at 56C, and stepping through shows that the character appears, even if it's cleared quickly after... why do you think it causes problems? 2 Quote Link to comment Share on other sites More sharing options...
HOME AUTOMATION Posted March 7, 2021 Share Posted March 7, 2021 Ok, I did some more research... >81 Column INCrement = OPCODES >80 thru >9F >E1 HTEX = OPCODES >E0 thru >FB >01 presumably >8301(CPU) So, perhaps these OPCODES are valid... ...still this seems to be right where everything goes wrong! I changed the value at >6010 to >6012 I changed the value at >6012 to >10FF(JMP $) If I place >0F >70(XML >6010), anywhere upto and including >E089 in GROM, I get the expected lock-up. Placed anywhere after >E089, I get the usual symptoms! Curious about the HMOVE vs. HTEX, right at this very same address? 1 Quote Link to comment Share on other sites More sharing options...

I have only delved into GPL as necessary so I do not have much of a handle on GPL instructions other than what I can find in the various GPL manuals (TI, RAG, Thierry, Martin, ...). I have so far missed HMOVE listed as the name of a FORMAT (FMT) instruction. Where might I find it? ...lee 2 1 Quote Link to comment Share on other sites More sharing options...
HOME AUTOMATION Posted March 7, 2021 Share Posted March 7, 2021 I imagine the disassembler did this to distinguish between HTEX string, vs. HTEX value,dest.. But, not knowing aforehand, can be confusing, I believed this was original source code, and thought it to be a programmer error. Quote Link to comment Share on other sites More sharing options...
Tursi Posted March 7, 2021 Share Posted March 7, 2021 Whatever it's called I have no idea, but the bytecode is valid and does what it claims to do. The code crashes after the jump into assembly language in all displayed instances, I don't think there's anything wrong with the GPL. After Fabrice's investigation, I'm dubious there's anything wrong with the assembly code either. It'd be interesting to understand what sequence is causing the issues, but I doubt it's invalid code.

asdf87 Posted March 11, 2021 Share Posted March 11, 2021 Hi - is there an up-to-date collection of both classic and modern ROMs for the FG? It seems the WHTECH one on p1 is from 2017 ... and we're now onto p56 of posts. I've just gotten my first 99/4A (they were never a thing here in Australia) so would love to get into it more. Thanks Brett. Quote Link to comment Share on other sites More sharing options...

Thanks Brett. There were, at least, some, of your countrymen, interested in the Ti99. The McGoverns were from Australia, and they created the Funnelweb software package. A package that had built in disk manager, editor, loaders, and so forth. Still much used by many ti'ers today. 2 Quote Link to comment Share on other sites More sharing options...

Indeed, there probably were! It was a thing, back then, for people visiting the US to come back with a suitcase full of sneakers (because they were so cheap) - I can imagine people also coming back with exotic computers like the TI ;) I've now got three - I just love the keyboard - and am planning on a few more.

I'm just going off my own experience - never saw one growing up ... Apples, Microbees, Amstrads, Commodores. I've now got an original black example and the newer cream coloured one with a US PSU - it seems the original uses both the 8.5VAC and 18VAC from the PSU but the newer one only uses the 18VAC - I've got a step-down transformer, but was thinking of either trying to replace the transformer with a 240V->18V version (Jaycar MM2011, but it'll only handle 1A), or just adding a 2.1mm socket and feeding the cream version with 16VDC ... not sure what to do about the black model ... but this is probably getting too far off-topic. I'll have a look if there's a hardware 120V->240V modification thread ... Quote Link to comment Share on other sites More sharing options...
Shift838 Posted May 12, 2021 Share Posted May 12, 2021 I have not seen this posted in the repository.

JMinter Posted February 18, 2022 Share Posted February 18, 2022 Hey. Is there a new thread or is this still active (last post was May 2021 :-O) I wonder if there is a new compilation with everything inside somewhere? I saw that the compilation on the main-post is from 2017. Maybe there were some hot releases in the last 5 years? Quote Link to comment Share on other sites More sharing options...

LouisB Posted June 27, 2022 Share Posted June 27, 2022 (edited) I recently picked up one of these at a swap meet. The case wasn't in very good condition. I ended up designing a new case based on the TI-99/4A Standard Cartridge Shell. Posting it here in case anyone is interested. https://www.thingiverse.com/thing:5420726 Edited June 27, 2022 by LouisB 4 Quote Link to comment Share on other sites More sharing options...

Also, cart. files need to be converted/encrypted for use with Win994a. 3 hours ago, toscar said: Demonattb.bin 90 kB · 3 downloads This is a .DSK image.
