  1. I am okay to join/speak at VITI-99 event. (VI = Virtual)
  2. Hi Sid, I think Michael Zapf already has a write up somewhere how to install MAME on the RPI4. (I do not have an RPI4, but came along this performance matrix https://ninerpedia.mizapf.eu/en/ti99/mame/mamereq) I am still troubleshooting my real iron Geneve 9640 RGB video output, but in parallel also run the MAME emulation on my PC to see if I can everything as on the real iron (need to sort out the RS232 connection, saw some write-ups and to sort out the mouse connection for now and how to maximize the screen, but should ask these in another forum). The TI/SIM I mainly used it on my RPI3B+ for gaming (together with MSX, NES, SNES, MAME/Arcade games, etc.), e.g. if we have a gaming competition like Bounce N Pounce, I am checking the other versions, like Bump N Jump on the NES (I have not used the disk-access control, I think the other emulators are a bit easier to use it)
  3. I took out all the chips and reseated them again (memory, Eprom MDOS 1.0, TMS9995 and the Yamaha 9938, but still the same result. Went back to use the Composite output, which is stable no issues here (only difficult to read MDOS and colours are a bit impacted). I think I am back at troubleshooting the GBS8200 devices, I think these are the issues: 1. I need to remove the capacitor: https://github.com/ramapcsx2/gbs-control/wiki/GBS-8200-Variants 2. Add 100ohm resistor across sync and ground for RGBs input https://github.com/ramapcsx2/gbs-control/wiki/Hardware-Mod-Library Corrects sync level for 75 Ohm sources (such as game consoles) 3. Add a Sync Stripper circuit to RGBs input. Try this if sync is never quite stable Maybe need a SyncStripper ? https://github.com/ramapcsx2/gbs-control/wiki/Inputs:-SCART-adapter,-optional-sync-stripper 4. Maybe I have this issue: Due to the high capacitance, the SOG extraction circuit in the 5725 sees too much of any eventual video content, instead of just the synchronization pulses. This leads to frequent short sync losses when the picture content changes rapidly, for example on a flashing screen. https://github.com/ramapcsx2/gbs-control/wiki/Sync-on-Green-Capacitor-Replacements 5. https://github.com/ramapcsx2/gbs-control/wiki/RGB-Potentiometers This would correct the RGB termination resistance to the TV standard 75 Ohm. or use a non-GB8200 type of device and find another RGB (RGBS) 15.7 kHZ converter to VGA * any recommendations out of these 4 solutions: 1. https://www.ebay.com/itm/15Khz-CGA-RGB-RGsB-RGBS-VGA-XGA-Converter-Scaler-/323316354604?mkevt=1&siteid=1&mkcid=2&mkrid=711-153320-877651-5&source_name=google&mktype=pla&campaignid=10693959030&groupid=108029226440&targeted=pla-293946777986&MT_ID=&adpos=&device=c&googleloc=1012728&itemid=323316354604&merchantid=116792603&geo_id=199&gclid=Cj0KCQjwvb75BRD1ARIsAP6LcqtCxKQNS-sVTBXtc9GdFoO68GqCRcuB9gNN6DXz-dt0fkoCVwQhMaEaAiFnEALw_wcB 2. https://www.ebay.com/itm/MDA-CGA-EGA-to-VGA-Converter-on-Altera-FPGA-for-old-computers/143574569650?_trkparms=aid%3D1110011%26algo%3DHOMESPLICE.DISCLISTINGS%26ao%3D1%26asc%3D20191002092920%26meid%3D24dab42c13724f8babec9a2a80553149%26pid%3D100889%26rk%3D2%26rkt%3D12%26sd%3D164149429851%26itm%3D143574569650%26pmt%3D1%26noa%3D0%26pg%3D2332490%26algv%3Ddefault%26brand%3DUnbranded&_trksid=p2332490.c100889.m5204 3. https://www.serdashop.com/MCE2VGA 4.
  4. Gee i did not manage to get a single point when trying the game.
  5. No I did not try that. I am guessing here, but might the video chip make a difference between composite output (which is stable) and rgb output or should it be other electronic components? Sent from my iPad using Tapatalk
  6. No rush, no problem, was just testing the term emulators to see if my rs232 ubergrom is working Sent from my iPad using Tapatalk
  7. The only item that does not work on my Geneve 9640 is a stable RGB signal to the GBS8200 device (and I have tried many other devices unless they are all having the same error?). I now have 2x GBS8200 version 5, which seems to be configurable to get a kind of stable screen and is workable, but once in a while I am loosing signal "no signal". (In the mean time I also made a Composite cable and that result in a stable output, but I cannot read the MDOS characters as it seems to be overlapping). The Geneve 9640 with GenMod v1 is working fine so far, everything works with Horizon, normal disks, RS232, etc. Question: 1. Let's assume the GBS8200 device is okay (and accepts 15 KHz) (is there an alternative to the GBS8200. I do not have SCART TVs here, that's more in Europe) I tried v4, v5 and now have the GBS8200 blue version with HDMI also does not work (split in 4 screens) or I am unlucky with all the cards I got so far (about 5x I think, I all sent them back). What can be the issue on the Geneve 9640 card itself, is there a component that can cause the "no signal" ? (I wired R, G, B, HSYNC, GND, used different cables, etc. all resulting in the same output) If there is a way to troubleshoot if there is a particular component giving this issue? (do I need to take out the chip GenMod and put it back, or the video processor ?) If the composite output is working fine, what other components are used for the RGB output to check on? (as the rest of the Geneve card works fine)
  8. I downloaded the TIXMT for ubergrom (the plop1, plop2, plop3) version (TIFILES Headers) is this the latest version or is there a newer one? (some issues I saw is if I entered from TI to PC (TeraTerm 2.3) the same letter on the same line it does not work (e.g. RR, but RTR works, if you use another letter, thus HARRY POTTER you cannot type) Also to set the colour some items do not go okay (e.g. set text colour, via FCTN-1 and 1) and using FCTN-7 and FCTN-9 returns a black screen, press again it is back.
  9. Yours is the normal adapter and it works already. The other one has 1x big PIN and I blew I my other adapter, but you can make your own with a Meanwell adapter. I did a write-up, published in Tijdingen and I think also at AtariAge.
  10. My experience - use a +5V at least 2A adapter The CF card, use a smaller version, I use 256 MB SAN Disk (also had the case it locks-up, then I reformat the CF card and with a script put all the volumes back, does not take long, but it works), e.g. make sure you can read the CF-card with a tool like TIDIR, and eject from your PC. Check the jumpers on the card, and the switch if it is turned-on. ... and today actually after 5 years, somehow I have the RS232 finally working (with NPDSK2PC program of Fred) probably the other programs were not okay. I have 2x nanoPEBs so far okay, but I prefer the TIPI nowadays
  11. @Schmitzi / @arcadeshopper all, Guess what (after how many years) I finally have the nanoPEB RS232 working as well with a PC connection. (I still need to try the connection from a TI to a TI). (as I just made the UberGrom RS232 interface for connection to the PC, I thought maybe test this nanoPEB one more time again). no clue what the issue was, +5V / 2A power - I do not think so, also not the cabling) USB - DB9 (MALE), gender changer (FEMALE - FEMALE), cross-connect (MALE, FEMALE), to MALE plug of nanoPEB settings upload at 38400, 8, E, 1 but I am using a different progra now which might be the case for the PC connection: of @F.G. Kaal Fred. NPDSK2PC (NanoPEB DISK to PC) NPDSK2PF NPDSK2PE NPDSK2PD NPDSK2PC
  12. (write up is maybe not 100%, but it might help other people) I finally managed to get it to work (if I remember correctly 2 years ago, I wanted to do this, because my nanoPEB RS232 did not work somehow) and now with UberGromHDX I can transfer from a PC files via Serial to the NanoPEB (without taking out the CF-card) but then came the TIPI (sidecar) in my life, but now I am building a network with multiple TIs and had a standalone TI that needed to be networked (with a standalone 32K or nanoPEB) burn the ATMEL CHIP (the .bin file eaprom_V_UG.bin) (I only programmed the ATMEL chip, in the past I wrote a procedure for this, see the last part) UberCart-Programming-v1-Aug-2017.pdf @F.G. Kaal Fred: It would be good to add a procedure the "how to" map the GROM base of the UART TTL device. http://www.ti99-geek.nl/Projects/ti99hdx/ti99hdx_ubergrom.html (my cable is USB-DB9 -- normal connector (MALE), to a DB9 (FEMALE) to DB9 (MALE) to the DB9 FEMALE UART device and the pins are mapped like on your photo. VCC to +5V, TXD to TXD, RXD to RXD, GND to GND) (thus no need for a gender-changer or cross-cable-adapter). To do the UART mapping: 1. Download the .zip here https://harmlesslion.com/cgi-bin/showprog.cgi?search=ubergrom 2. as I use this on a standalone TI (with NanoPEB attached first, but actually want to use it with 32K attached only) how to get the file to the TI: a. Used the CF-card on my PC and saved the gromcfg.dsk to a volume on the CF-card (using the TIDIR tool of Fred ti99-geek.nl website) b. then using the nanopeb in TI-BASIC: CALL MOUNT(2,Volume) c. with E/A option 5 (of the UberGromHDX module) DSK2.GROMCFG 3. in GROMCFG now press CTRL F and browse with > to the >983C then press A (for >A000) then press U (to assign UART) 4. then SAVE (DSK2.UARTSAVE) it overwrites the Ubergrom 5. press FCTN 7 then make sure the CTRL B (Base is ON), rest is OFF (not sure if this is correct, but it works for me) 6. Start TI99HDX 9.1 (settings are for me on COM3 for the USB port mapping) 38400, 8, E, 1 and at communication status DTR and RTS are on (rest are all off) 7. start module > Editor Assembler V option 7 Utilities option 5 UberHDX it will initialise quickly and on the PC you will see also that it is initialized then for source enter SRC: HDX1.
  13. @arcadeshopper @InsaneMultitasker @jedimatt42 Maybe the other MDOS disk can be updated to include the GPL files? This MDOS 6.50 disk (1440. DS/DD) has the GPL, GPM, GPN, GPO files added, so that from MDOS you can go to the TIMODE (enter GPL from the MDOS prompt) and in GPL mode use DSK8. to load files of the HorizonRamdisk AUTOEXEC2 need to be installed on the HorizonRamdisk and be renamed to AUTOEXEC GeneveMDOS.dsk PS. you will get a command error in MDOS as I try to use "CAPS ON" by default in the AUTOEXEC to start with uppercase characters (did not get it to work yet)
  14. This seems all to work fine for the last weeks, with having it being turned-off for a week, until now it nicely starts-up each time of the HRD
