humeur Posted May 11, 2021 Share Posted May 11, 2021 Hello, I am looking for a copy of the two eprom tms2716 of the video extension card for the TM990/189 or TM990/189 card. Or if one of you has that and would like to dump it on me. thank you in advance Jean Louis Quote Link to comment Share on other sites More sharing options...
Stuart Posted May 12, 2021 Share Posted May 12, 2021 I got the impression that the two sockets on the video card itself were for user programs - so the sockets are empty when you bought the card. Support for the video card is built into University BASIC. As MAME emulates that, MAME must include the ROM dumps? See lines 440 onwards of https://github.com/MisterTea/MAMEHub/blob/master/Sources/Emulator/src/mess/drivers/tm990189.c. 2 Quote Link to comment Share on other sites More sharing options...
+Ksarul Posted May 12, 2021 Share Posted May 12, 2021 Look at lines 920 to 956, as they show two different ROM loads: one that loads the standard boot ROM and the Extra ROM, and the other that loads both of those (in their normal spaces) and an additional pair of demo ROMs into the Video Card spaces. It looks like no other ROMs are needed to operate the video card. . .as @Stuart has already noted that University BASIC supports it. 1 Quote Link to comment Share on other sites More sharing options...
humeur Posted May 12, 2021 Author Share Posted May 12, 2021 Hello Thank you for your answers on the subject ER2289 @Ksarul Jim for the line 920 to 956 these are the standard basic eproms and the others are a game, you just have to see the file with a hex editor demo1000.u13 and demo1800.u11. I could be wrong, but I think I'm right @Stuart The two eproms would therefore only be the games that are loaded by Load0 or Load1 but the system already manages the tms9918 at the start of the instructions. The tms9918 card could work without these eproms I'm less good than you two. Jean louis 2 Quote Link to comment Share on other sites More sharing options...
+Ksarul Posted May 13, 2021 Share Posted May 13, 2021 C'est ça, @humeur. Les EPROMs DEMO1000.U13 et DEMO1800.U11 ne sont pas nécessaires pour la carte vidéo. Quote Link to comment Share on other sites More sharing options...
humeur Posted May 13, 2021 Author Share Posted May 13, 2021 Thank you to both of you, since indeed all the management of the vdp is already in the Basic rom with all the commands. In French we say what an idiot not to have seen it. thank. Jean louis 1 Quote Link to comment Share on other sites More sharing options...
