+videofx Posted September 29, 2018 Share Posted September 29, 2018 Hi everyone! Just got my first PEB. First i received ny 32k sidecar today. With XB size i get 11840 bytes of stack space and 24488 bytes free of program. I get that with the sidecar and the 32k in the PEB so i guess this is normal? No the drive in the PEB gives either Error 16 or 31 when i use Disk manager 2 to format a disk. Id it the drive or controller? I have tried brand new Verbatim and KAO disks. They format fine in my other computers. I would appreciate any help! Thanks Quote Link to comment Share on other sites More sharing options...

Running both will NOT give you 64K and might be causing your issues. Congrats on the P-Box..... photos please! Quote Link to comment Share on other sites More sharing options...
+videofx Posted September 29, 2018 Author Share Posted September 29, 2018 Sorry i wasnt clear. I tried to format the disks just using the PEB without the sidecar. So with just the PEB i was getting the disk errors. I will post some photos Quote Link to comment Share on other sites More sharing options...
Shift838 Posted September 29, 2018 Share Posted September 29, 2018 Sorry i wasnt clear. I tried to format the disks just using the PEB without the sidecar. So with just the PEB i was getting the disk errors. I will post some photos Please post photos of the drive you have installed too. The TI PEB (stock) came with a 90k Single Sided/Single Density drive. If it's stock, make sure you are selecting 40 track and SS/SD. Also typically the LED is at the top on stock drives and if so make sure the floppy disk index hole (small round hole) is at the top of the of the drive.

+Ksarul Posted September 29, 2018 Share Posted September 29, 2018 Also, make sure the disks you are using are DD and not HD rated. HD disks will not work well. . .if at all. Quote Link to comment Share on other sites More sharing options...
+videofx Posted September 30, 2018 Author Share Posted September 30, 2018 Yup they are not HD i format them fibe on my trs80, commodore and Atari Quote Link to comment Share on other sites More sharing options...
+Ksarul Posted September 30, 2018 Share Posted September 30, 2018 Which drive do you have, the Shugart or the MPI? The MPI is really easy to figure out, as it has the built-in disk-chucker mechanism (door opens and pushes the disk out, sometimes at great speed). Makes a huge clunking twang sound when it opens too. . .they used these a lot in TRS-80 land (MPI-51 (single sided) or MPI-52 (double sided)). On either of these TI drives, the notch definitely goes towards the light. Quote Link to comment Share on other sites More sharing options...
+videofx Posted September 30, 2018 Author Share Posted September 30, 2018 I have no idea what I have so hope you guys can identify my PEB and drive 1 Quote Link to comment Share on other sites More sharing options...
Shift838 Posted September 30, 2018 Share Posted September 30, 2018 (edited) notch to the top. If you don't have the Disk Controller manual the link is below. Page 43 gives you the error codes for the DM cartridge. HERE Edited September 30, 2018 by Shift838 Quote Link to comment Share on other sites More sharing options...
+Ksarul Posted September 30, 2018 Share Posted September 30, 2018 That's an MPI-51, and as noted, the notch goes to the top. Quote Link to comment Share on other sites More sharing options...
Omega-TI Posted September 30, 2018 Share Posted September 30, 2018 << HERE >> is the manual for the disk drive. Odd errors you are getting. At first I was wondering if it was a 35 track drive, then wondered if the heads were dirty. Maybe the it's just plain broken after all these years?

At first I was wondering if it was a 35 track drive, then wondered if the heads were dirty. Maybe the it's just plain broken after all these years? I was thinking the same thing. Let me try 35 tracks and see what happens. The guy on Ebay said everything was working so I bought it. I am waiting for him to respond.

+Ksarul Posted September 30, 2018 Share Posted September 30, 2018 Also, double-check that the drive cables are still properly seated. A connector may have come loose at the drive end during shipment. . . Quote Link to comment Share on other sites More sharing options...
+videofx Posted September 30, 2018 Author Share Posted September 30, 2018 Also, double-check that the drive cables are still properly seated. A connector may have come loose at the drive end during shipment. . . Yup, I removed the drive and everything is connected. I tried another TI disk controller. You hear the head step the 40 tracks as it initializes the disk. Then when it finishes the 40 tracks you get a RRRR from the heads then ERROR 31. I also tried the Corcomp 9900 and same thing except instead of error 31 I get ERROR 41. Here are some photos. Can anyone fix the drive?

+Ksarul Posted September 30, 2018 Share Posted September 30, 2018 Wasn't there a bug in DM 2 for the selections on SD/DD? ISTR that you had to hit No on the SD line, because the answers were reversed. . . The fact that three different controllers have the same symptom does point to a drive issue though. Is the grease on the drive rails hardened? Sometimes that will prevent the heads from getting back to the proper starting point, and indicate no disk is present because it can't find the formatted sectors on the tracks. The fact that it is going through the motions during the format run tells me the controller is apparently working fine. You hear the stepping and the long swing back to start--it just fails to read.

Omega-TI Posted September 30, 2018 Share Posted September 30, 2018 If anyone has any working drives for sale I want to a 2 drive system You might want to investigate << THIS OPTION >>. The device can perform as TWO disk drives in your P-Box and you will never have to mess with head cleaners or worry about aging mechanical parts or lubrication issues. The device can even pay for itself over time because you'll not need to buy a lot of space hogging diskettes to get strewn all over the place.

But I need a 5 1/4 for the hundreds of TI 99 software I have on disk. Quote Link to comment Share on other sites More sharing options...

+videofx Posted October 1, 2018 Author Share Posted October 1, 2018 I took the metal shield off and I can see the disk spin, I can see the heads move in and out and go to all 40 tracks when I format and then move all the way back. So the only thing I can think of is clean the heads. Anyone can please tell me how to get at the heads to clean them? Thanks Quote Link to comment Share on other sites More sharing options...

+Ksarul Posted October 1, 2018 Share Posted October 1, 2018 PC disks are generally jumpered to act as DSK2. . .just select 2 as your drive with it connected and it should see it. Quote Link to comment Share on other sites More sharing options...
