  1. My Geneve has heat sinks on the regulators, hence it cannot use the case - but the back part of the case helps with the correct orientation and seating. When you close the PEBox's lid, the foam will press the Geneve into its slot. As you can see, I've done it with the Geneve and HFDC. The box is upright (drives on top).

  3. Not a BwG card: see this picture: https://www.s-n-u-g.de/bwg/index_fr.php The TMS9901 is typically a sign of a CorComp card. My CorComp card has a 1773 controller, but I have seen the 2793 mentioned (on whtech?), they are software compatible.
  4. There is no simple PAL video cable, the console has outputs for YUV (aka YCbCr/YPbPr?) component signals. Some modern TVs can take these directly (my LG 42LF65 did). Otherwise, the PAL modulator mod gives you the composite signal (slightly better quality than from US NTSC consoles), or you could use the SCART/Peritel RGB modulator (mostly sold in France) for the best quality picture. A schematic for an RGB-enoder was in the November 1988 issue of the ChicagoTImes, I built this twice, good stable picture. Then there are upgrades based on the 9938 VDP ("80column cards"), or the F18A for VGA output.
  5. With proper address decoding, only one CRU device is active at any time - so this shouldn't be an issue. The 9901 in the console isn't fully decoded, so keep out of it's address range! http://www.mainbyte.com/ti99/schematic/schematics.html has several schematics, the FDC card has the '251 connected directly to CRUIN.
  6. Since CSYNC comprises high frequency signals in the range 15.6kHz, I would connect it to HSYNC first. VSYNC is the 50/60Hz frame signal, and you would miss the line synchronization if using this input only. If this fails, try parallel connection to H and VSYNC If that fails, too, try a circuit with a LM1881 sync separator (8-pin IC and some passives)
  7. Wouldn't that compare R0 to 2 (immediate value), C R0,R2 compares two registers. The assembler option "R" does an operation like "R2 EQU 2"
  8. From the docs (tiif.txt): "Since Windows XP and newer doesn't allow direct access to the IO-port of the LPT-card, a system kernel driver is required. I decided to use TVicPort (http://entechtaiwan.com/dev/port/index.shtm) which is free for non commercial use. This combination was successfully tested on a Windows 10 32 Bit PC with an onboard LPT-port and a Windows 10 64 Bit PC with a PCIe LPT-port."
  9. just found a current version: https://groups.google.com/forum/#!topic/comp.sys.ti/_xbwmWs5gXY http://pengels.bplaced.net/index.php/tiif
  10. In comp.sys.ti was a post about a new version of the PC-IF: https://groups.google.com/forum/#!topic/comp.sys.ti/WT3qdYD1tZE the link to acg-bonn.dyndns.org/~en/downloads/files/tiif.zip still works, the file contains schematics and software from DOS to WIN32
  11. How about MOVB *R1,*R1 ? Still testing for 0 without using any extra register, but slower (about 2 cycles).
  12. My old LCD-TV (LG 42LF65) took the TI signals on YPbPr input - best possible quality without any modulator! The RGB circuit in "Chicago TImes" (ca. 11/1986) is quite easy, only a handful of transistors and passives. That is my favourite, if you have a RGB-capable Scart input.
  13. Another option would be the Mini Memory cartridge, it contains 4K RAM and the Line-By-Line-Assembler cassette tape. There is no need for a PEB or other expansion hardware, just a cassette recorder and the cartridge (with tape).
  14. Dear fellow TI'ers, the TI-Club Errorfree invites you to the international TI-Treff 2016. The 31st international TI Treff will be held from September 30th to October 2nd in Denmark. The location is the Hotel Svalen in Hedehusene near Copenhagen. The Treff starts on Friday and goes to Sunday afternoon. Friday is for set-up of the computers, and we'll have dinner at the "Porterhouse" in the city. Saturday is for demonstrations of hard- and software, talking & exchange of ideas, auction, club presidents' conference and a dinner, afterwards computing till early morning (if you desire...). Sunday is for more sharing of experiences and packing, or a tour of Copenhagen. There is a conference room in the hotel at our disposal, rent (and dinner) is included in the room price, so we'll take a fee from "external" visitors. At the Saturday dinner, this years Edgar Mauk award winners will be announced. Prices: A room is DKK 2390 for two nights (approx. EUR 319), including the meeting room and dinner. Since we got allotted some rooms, please book (as soon as possible) your room through: Jens-Eike Hartwig, phone +49-461-9787778 (best between 20:00 and midnight CEST) or je_hartwig(at)yahoo(dot)com The address: Hotel Svalen Roskildevej 333 DK-2640 Hedehusene Please do not book through the hotel or booking websites, since the rooms are pre-booked!
