    I downloaded this game from tigameshelf.net.  The disk version is supposed to auto load from extended BASIC.  It loads part way and then quits with the LED on the TIPI solid on.  I then have to use tipi:9900 to reset the TIPI before it will respond to the TI again.  The load program has 3 lines.  I have determined that the issue is in the end of the last line.

     

    3 CALL LOAD(“DSK1.TST”):: CALL LINK(“RUN”)

     

    I loaded it in classic99 and it works there.  There is also a file on the site with a bin suffix, I couldn’t get my FG99 to recognize it at all.

     

    Any ideas as to what is wrong?

    A new version of the TIPI/32k that also supports some of the other RAM expansions.   Use some of the PI’s io pins to be able to turn features on/off when you “CALL TIPI”.  So if a program won’t run from expansion RAM, you could easily shut it off.  Maybe even by having a config file in the same directory that would set up RAM expansion, drives, etc.

    I got the 0.56 ohm resistors in today.  Now I get 5.2 volts immediately.  Tested resistances on motherboard.  They were all in the k ohms range.  Hooked everything up, no picture.  Tried removing the VDC, but a pin broke off.  Ordered one.  I figure to test it in one of my working machines before trying it in this one.  I will need to De-oxit  the Socket and Check continuity.  I may have to replace the socket.  Pins on one side are shiny, but some of them on the other side don’t look good.  But, hey, progress.

    likely they are not TIFILES format. open the folder in the web interface: http://TIPI:9900   and look at the files, if there's a big ? in the icon then it's not tifiles format, select all the files that are ? and then select from the pulldown "convert to tifiles"

    Thanks!  That was it although two of the files won’t convert.  I will try re-downloading the zip tomorrow and see if that helps, but I have plenty to play now.

    I am trying to get this to work.  I have ADVENTURE on the FG99. I downloaded these modules and copied them to my TIPI/32k.  I set the directory I copied them to, ADVENTURE, as DSK1.  When I start the program and it asks where the database is, I type ‘DSK1.ADVENTUR’.  The light on the TIPI flashes and I get ‘FILE NOT FOUND’. If I type ‘CS1’, it goes into the cassette dialog.  Please help me get into these adventures.

    Yes, it comes up to +5 immediately.  I started with R9 and R10 because they had a lot of rust on them before I cleaned the board.  Thanks for the answer, I did order some 3 watt, 1% resisters yesterday.  I figured better too large than too small.  If they don’t fit the holes, I can use jumper wires to test.

    The SAMS card supplies the 32 KiB expansion RAM in addition to the extra RAM that can be paged into one or more of the 4 KiB blocks addressed in that expansion RAM (>2000, >3000, >A000 – >F000).

     

    The 32 KiB sidecar has only the 32 KiB of expansion RAM.

     

    You can have one or the other in the system, but not both.

     

    ...lee

    I believe you can set a jumper on the TIPI/32k to disable the 32k and use SAMS if you want.  Arcadeshopper can give you more info.

    For the transistors, I'd just get replacements and see if it fixes the problem.

     

    Personally (but I'm no expert), I'd try replacing in order:

    -- Q1 and Q2

    -- C15

    -- D9 and D10

    -- U3

    -- C11 and C13

     

    I would think the resistors are OK unless they are visibly damaged.

    Thanks, I was thinking the transistors first.  Nice to have confirmation.

    Check the output of U4 pin 2 (which may be an oscillating signal - not sure). Does this signal change over the period it takes the 5V rail to come up? If yes the problem likely to be in the components around U4. If no, problem likely to be in components around U3.

    Thanks, I will test and get back to you.

    I am working on a very corroded beige unit.  I soaked the parts in citric acid solution to remove the rust am am now testing each part, starting with the power supply.  The 12 and minus 5 volt rails seem fine, but the plus 5 volt rail takes about 30 seconds to come up and then stabilizes at 5.207 volts.  This doesn’t seem correct.  Unfortunately, TI used a complicated circuit for the plus 5 volt rail instead of a 7805.  Anyone here willing to help me troubleshoot?

    I have made some changes to my system.  Got pin the right angle micro USB adapters so I can finally use the speech synthesizer.  Used Parsec to test it.  It works but I suck at the game.  Also I had been using an AV2VGA converter and a 17” monitor as an upgrade to the 10 inch monitor I used for testing.  I got the pictured TV from eBay it is 15” which seems to be a better match to the computer.  Big enough that my old eyes can see things but not so big that it looks really pixelated.  I am still trying to test the tape player.

    The Pascal system that's complete and useful for the TI is the UCSD Pascal, running on the UCSD p-system.

    But there are several flavors of Forth available for you.

    I bought the manual for fbforth.  Just got it Saturday.  Is the p-system available and can stand alone programs be created using it?  I want to be able to create programs that can be used by anyone with a means to load them.  I thought I was doing that with Turbo Pasc 99, but discovered that the program only works when my FG99 has Editor/Assembler loaded.

    Just before you get too deeply involved with Turbo Pasc'99, you should realize that the lack of structured data types and dynamic memory allocation means that it's really not worth using at all. It's not Pascal, it's not even Pasc, it's just about P...

    I plan to move on to FBFORTH, but I did some programing in Pascal Back in the 80s.  Figure to get my feet wet with the TI using it and then move on.  Don’t plan on writing any major software either.
