+Atari2600PAL Posted May 9 Share Posted May 9 I have my first PEB (push button, but with the short backplane) which I've taken apart and done the power lead switch over for 240v (as in UK) and it powers up and connects to my 99 fine The 32kb memory card appears to be working according to TI XB (24480 bytes of program space free?) My 838-Speech card works fine (many thanks @Shift838) when I try Parsec It has an RS232 card, but I'm not sure how to test that Finally, it has a CorComp 9900 Disk Controller (DS/DD) and therein lies my biggest issue When I power on the 99 the menu screen has option 1 for disk manager, but nothing happens when I press 1 other than the disk light comes on for a few seconds. After that, pressing 1 always brings the disk light on for a few seconds but none of the other options (like 2 for TI basic or space for colour bar) respond until I switch the 99 off/on My final problem is the PEB power switch (push button type) is a bit broken and is "always on". Not sure if it's possible to get a replacement or whether it just needs a new spring (at least it's stuck on and not off!) Any thoughts and/or help/advise would be greatly appreciated please Many Thanks Quote Link to comment Share on other sites More sharing options...
atrax27407 Posted May 9 Share Posted May 9 My system is set up for convenience and not because of a malfunction. I have EVERYTHING plugged into a power strip. I turn on my system from there. That powers up everything EXCEPT for the console (which is supposed to be powered up last) and is OFF and must be turned on separately and a standalone 5.25" DSk3 and my printer which is seldom used these days. It has been set up this way for more than 20 years and has worked flawlessly. 1 Quote Link to comment Share on other sites More sharing options...

Any thoughts and/or help/advise would be greatly appreciated please Many Thanks Disk manager is on a disk.. hence.. why it is trying to load it when you select it. and it's just looking and looking which is why you have to power cycle If you need a disk I can make you one, lmk I can put it in my store for a couple bucks + shipping Also I recommend replacing the roms on that board with the miller's graphics roms which get rid of that title screen and fix some compatibility bugs I sell those as well Power switch is likely bad so you will need to replace it or just use a power strip Greg 2 Quote Link to comment Share on other sites More sharing options...

Not keen on opening it all back up again tbh as I had to drill out a rear screw to get into it to do the power mod. But I made sure I didn't over tighten the screws when I put it back together! I'd like to test if the drive let's me read/write or load/save (to prove it works) but I guess without the disk manager disk I won't be able to format a disk? (I have an FG99 if there's something I could run from that) Thanks Quote Link to comment Share on other sites More sharing options...

+FALCOR4 Posted May 9 Share Posted May 9 After searching for quite some time to find a replacement switch for the push button PEB, this is the closest that I've been able to find. I haven't installed it yet, but it looks like it might work. I don't have the original PEB mount for it and will have to fabricate something. So, if it is something you're interested in trying, definitely look if over closely to see if it will work for you. Quote Link to comment Share on other sites More sharing options...

Bare-in-mind, that CEMF from the PEB's big transformer, and also power returned from spinning motors, can on occasion damage low-power equipment connected in a row together on a power-strip, as tripping the switch on the power-strip, removes all the loads from the low-reactance path to the local grid, but leaves them connected to one another!

It addresses bugs and other things as well as brings back the regular TI boot screen. I believe @arcadeshopper sells them.

Thanks, will look into it I’ve tested the drive with tunnels of doom disk and it gives me an error 6, so am suspecting the drive is faulty (if the floppy is ok, but I’ve no way to test that). So not sure what to do at the moment. Will try the disk manager disks @arcadeshopper is sending me to see what happens before I start hunting for a new drive Quote Link to comment Share on other sites More sharing options...

Will try the disk manager disks @arcadeshopper is sending me to see what happens before I start hunting for a new drive I would suggest getting rid of the floppy drive if you don't have any floppies anyway. Just go with a Gotek, you can use floppy disk images on a thumb drive. just cycle through teh disk images on there. Make sure if you do to use the FlashFloppy firmware. It's much easier to use. Many of us TI'ers and other vintage computer enthusiasts are using these now. super easy to get disk images onto a fat32 formatted USB thumb drive for any type of PC. Very easy to make your own disk images with TI99DIR and TIIMAGETOOL just to name a couple.

+Atari2600PAL Posted May 10 Author Share Posted May 10 I’m into floppies, my C64 has one and I, rather perversely, prefer floppies/tapes over the SD cards I have for each system I’m collecting. Takes me back to my youth in a nostalgic way I guess For a more practical use on the 99 I have the parts for a TIPI on the way Would just be nice to have a working floppy in the PEB even though, in reality, I probably don’t really need one As a full time carer currently it’s more about the collecting/playing around for now as I don’t get much time to myself to do anything more substantial or worthwhile with my hobby Quote Link to comment Share on other sites More sharing options...
+Atari2600PAL Posted May 10 Author Share Posted May 10 Thanks to @arcadeshopper pointing me to the instructions for the DM2K utility I've managed to use it now But when I selected to format a disk the disk light came on but there was no mechanical noise whatsoever from the drive, so after 15 minutes I gave up on that I then tried to do a directory of my tunnels of doom floppy and again got a light but no sound, followed by an error 6 in DM2K (the same error I got with tunnels of doom cartridge) Does this sound like I need a new floppy drive please? or could it be the controller? Many thanks Quote Link to comment Share on other sites More sharing options...
+Atari2600PAL Posted May 10 Author Share Posted May 10 Just pulled the drive so I could see what happens when it's accessed and, apart from the red light, its as dead as a dodo No obvious visual signs of any issues with components and cables so I guess I need to find a new drive to try as I don't have any real electronic knowledge (basic soldering and checking voltages and continuity are about my limit) Quote Link to comment Share on other sites More sharing options...

Takes me back to my youth in a nostalgic way I guess I still have a 1541 on the shelf, and one day I'll try to sample the sounds of that drive to be included in MAME (for the C64, of course). There's nothing like the head hammering of a 1541. 🙂 1 Quote Link to comment Share on other sites More sharing options...

Tried the dm2k, after a faltering start, and that plus other tests/checks suggest the drive is no good (and beyond my ability to try and repair) Have ordered a couple of working half height drives to check if the controller is ok 1 Quote Link to comment Share on other sites More sharing options...
