+Schmitzi Posted June 11, 2015 Share Posted June 11, 2015 oh yes, sorry, you told me before to differ between AC and DC-output. I have to review that. Here I was just wondering that there is one powersupply with -5V and that it is for the 99/4. Kommt Zeit, kommt Rat Quote Link to comment Share on other sites More sharing options...

globeron Posted June 12, 2015 Author Share Posted June 12, 2015 Thanks Ksarul! Ralf - Yesterday I have also seen the "large" adapters, but AC 9900/N2 format, the plug has blue color inside (like the 99000/N2) I forgot to make the pictures, but I made the one of the AC9900/N. Will show tomorrow, then we can update the .xls as well. Quote Link to comment Share on other sites More sharing options...
globeron Posted June 12, 2015 Author Share Posted June 12, 2015 European AC 9900/N version with the "bigger pin-hole": (from Mr. Antoon in Netherlands, hope this one will work!) http://www.pic-upload.de/view-27337452/20150610_060712.jpg.html http://www.pic-upload.de/view-27337453/20150610_060827.jpg.html http://www.pic-upload.de/view-27337454/20150610_060809.jpg.html http://www.pic-upload.de/view-27337455/20150610_061412.jpg.html http://www.pic-upload.de/view-27337456/20150610_061432.jpg.html 1 Quote Link to comment Share on other sites More sharing options...
+Schmitzi Posted June 12, 2015 Share Posted June 12, 2015 thx. Entered BUT, this here is an AC/DC (not AC as mentioned), with-5Volt with Big-Pinhole , so it should be for the 99/4A ? Quote Link to comment Share on other sites More sharing options...
+Ksarul Posted June 12, 2015 Share Posted June 12, 2015 So far as I've seen, if the power supply is an AC/DC type. It will have the big plug hole and will be for a 99/4. The 99/4A only used AC/AC power supplies, as did the later 99/4s (all of which had the smaller pins). The DC supplies were replaced with AC supplies relatively early in the life of the 99/4, so they were not too well documented prior to this exercise. Thanks for starting th thread, Globeron, as now anyone who needs the information will have a way to find it! Schmitzi's list of Power Supply types will also be very useful, as we can eventually link the P/S types to the console styles they came out with.

globeron Posted June 27, 2015 Author Share Posted June 27, 2015 (edited) Good news, after replacing the fuses I got the TI-99/4 with volume slider, internal speaker and sound jack to work! (only the red indicator led light does not work). Note the AC9900/N adapter (not /N2 !) has 3x fuses (the T315mA is a bit difficult to see when it is in the plastic cover) [Edit] -> this is a 220V adapter (for Europe) Thus: 1x 160 mA 1x 2A 1x T 315mA It is a European version TI-99/4 and it works with a PAL-modulator (similar as the one for TI-99/4A), the sound comes both from the TI-99/4 itself (via the internal speaker) or via the sound-jack in the front, but at the same time via the LCD-screen as well. Tip: Sometimes the TI hangs (the typical Texas hang-up sound) during startup with the PAL modulator, but without PAL modulator you can verify if the TI starts (as it has an internal volume speaker, then you will get the normal beep), plug the PAL modulator back in/out a few times when needed and the screen is back (not sure what is causing this, but it works).

+Schmitzi Posted June 28, 2015 Share Posted June 28, 2015 ...just an update.....and some more powersupplies from other vendors. If you have more powersupplies, for any TI-related part, just send me a picture, with the part-no. , voltage a.s.o. readable, to 99er@toxic-instruments.com, and I will add it to the list. 1 Quote Link to comment Share on other sites More sharing options...

+Schmitzi Posted August 9, 2015 Share Posted August 9, 2015 I paste it here over from the other thread, to keep the topic here http://atariage.com/forums/topic/241337-ti-994a-beige-consoles/?p=3296158 GLOBERON WROTE: Hi Schmitzi, (info below should actually go to a /4 discussion, not beige anymore): with Ksarul we went through an whole check as well for /4 (as mine came without power and video cabling and had to get them to work). My view is that there are 4x different /4 versions (and a few more) 1. /4 with volume slide + speaker (built-in) + earphone plug (at the left front of the TI) and needs a 9900/N power adapter "1x BIG-PIN" (220V, you have the details), the shoeform There are 3x fuses in this adapter: http://www.globeron.com/freedownload/services/TI99/AC9000N-adapterTI99-4-special.jpg and 6-pin DIN plug which needs a PAL-Modulator (European version) + +5V ++ ++++ GND + +12V ++ ++ -5V See also Fabrice website: http://www.ti99.com/ti994pow.htm 2. (last week on ebay from Germany) /4 with volume slide + speaker (built-in) + earphone plug (at the left front of the TI) and needs a 9900/N power adapter (220V, you have the details as per above), the shoeform and 5-pin DIN plug which needs a NTSC modulator or direct cable using composite plugs 2.5 --- ***not too sure if there are versions with a volume slider, but not having a speaker built in, but having an earphone plug (I cannot remember if I read it somewhere) 3. /4 without volume slider, no speaker built-in, but it has a earphone plug (at the left front of the TI) and needs a 9500 power adapter (117V) AC9500 (pins 1,2: 18 VAC .18 VA (or 18VA ?), Pins 2,4: 8.5 VAC .128 VA). 5-pin DIN plug which needs a NTSC modulator or direct cable using composite plugs 4. /4 without volume slider, no speaker built-in, but it has a earphone plug (at the left front of the TI) and needs a 9500 power adapter (117V) AC9500 pins 1,2 16.0VAC 36.0VA and pins 2,4 8.0VAC 1.0VA) see the website below. Note that 3 and 4 are both have an AC9500 adapter, but with different specifications (no clue why ?) ** Then there are /4 systems which had to be connected directly to the monitor (see http://www.ti994.com/1979/peripherals/) but also the cable was identified (like the direct composite plug cable), but has to do with the FCC regulations of the RF-modulator. ** Furthermore the /4 Keyboard has more pins than a normal /4A keyboard and the spacebar is connected separately I took some pictures of my spare keyboard: 20150804_110743.jpg 20150804_110715.jpg 20150804_110825.jpg More info: www.ti994.com/ http://www.99er.net/994.html http://www.mainbyte.com/ti99/computers/ti994.html Quote Link to comment Share on other sites More sharing options...
+Schmitzi Posted August 9, 2015 Share Posted August 9, 2015 I think Powersupply as described in No. 4 (117V) is correct, but No. 3 should be 120 Volts (shown on your pics you send me a while before) Here also what I have worked out on these infos: CONSOLES: as PDF: TI-99-4ALL-Consoles-v1.05-ano.pdf POWER-SUPPLIES: as PDF: TI-99-4x-PowerSupplies-v09.pdf 1 Quote Link to comment Share on other sites More sharing options...

+Schmitzi Posted August 9, 2015 Share Posted August 9, 2015 > the 2nd entry US version, I think the 9900/N is also a BIG-pin one .... which one do you mean ? I can not figure out. ---------------------------------------------------------------------------------------- (here an interim for the powersupplies, with some color-coding for the PINs and ths jacks, and remarks where are Pics missing) TI-99-4x-PowerSupplies-v1.10.pdf (and for the consoles) TI-99-4ALL-Consoles-v1.06-ano.pdf 1 Quote Link to comment Share on other sites More sharing options...
globeron Posted August 10, 2015 Author Share Posted August 10, 2015 Re: .... which one do you mean ? I can not figure out. >> the 2nd line where all TI's are listed the TI /4 --> (9900/N Normal Pin) --> I think this is a BIG Pin as well.
