Guest Posted March 16, 2015 Share Posted March 16, 2015 (edited) Hi recently bought an Indus GT - with a declared "G5" error. however, the actual fault seems slightly different. it'll always do its first seek/load direct from power up, then just fails to do anything with any follow up requests. ie will boot to dos, but then a Directory List request results in nothing happening same with menu disks - can boot to menu, then selecting either "format/copy/create menu" etc - results in NO activity on opening up the casing it's clear that the drive mechanism does not do anything after the initial activity any help at all would be appreciated, or directions to someone (preferably Uk-based) who can repair, or advise (for a fee) on how to repair. thanks Edited March 16, 2015 by Guest Quote Link to comment Share on other sites More sharing options...
Paul Westphal Posted March 16, 2015 Share Posted March 16, 2015 Clean the heads with a qtip and rubbing alcohol...in fact take it apart and clean everything! You may try looking at the track 0 sensor- common problem. Best electronics also sells the upgrade rom to make it run faster and time out quicker.

Guest Posted March 16, 2015 Share Posted March 16, 2015 Paul, thanks for reply how do i look at the track 0 sensor? where is this? Quote Link to comment Share on other sites More sharing options...
MrMartian Posted March 17, 2015 Share Posted March 17, 2015 If it boots to DOS, then the drive can happily read a disc, no problem with the heads or track zero sensor.... What DOS are you trying? Quote Link to comment Share on other sites More sharing options...
Guest Posted March 17, 2015 Share Posted March 17, 2015 (edited) hi the problem is any "second" instructions. ie - it'll power up any disk, dos/multiboot or other the problem then occurs/manifests itself when you then make a menu selection after boot up it just times out when using Dos the error msg is : error 138 when using anything else - it just does nothing does anyone know of any help files/movie clips that walkthru servicing these drives?

Rybags Posted March 17, 2015 Share Posted March 17, 2015 A weird one. What if you power on the drive but don't boot up the computer until the drive has stopped it's initial seek etc? Loading Dos isn't a single operation, it's multiple status and read commands. The only thing in common you seem to have going is that everything's OK so long as the drive motor runs, but once it spins down it doesn't want to go again. How about load Dos then power the drive off/on again? In that case stuff like listing directory should work. Or maybe load a menu Dos like 2.x and quickly try commands before the drive spins down.

Guest Posted March 17, 2015 Share Posted March 17, 2015 that's what i found - selecting "A - list directory" before the activity has ceased means it will list the drive contents. however if i wait until the disk has spun down, it doesn't restart.

MrMartian Posted March 17, 2015 Share Posted March 17, 2015 Buggy firmware..... Can you write an EPROM? Quote Link to comment Share on other sites More sharing options...
Guest Posted March 17, 2015 Share Posted March 17, 2015 no, unfortunately. is there a simple way to do this? or is it a case of buying a new rom chip? Quote Link to comment Share on other sites More sharing options...
flashjazzcat Posted March 17, 2015 Share Posted March 17, 2015 no, unfortunately. is there a simple way to do this? or is it a case of buying a new rom chip? Got a burner here... we could fix something up to go in the box with the keyboard? Quote Link to comment Share on other sites More sharing options...

flashjazzcat Posted March 17, 2015 Share Posted March 17, 2015 Not sure how big the Indus OS is. Anyone? Quote Link to comment Share on other sites More sharing options...
MrMartian Posted March 17, 2015 Share Posted March 17, 2015 2732... Which I know you have a few of, but no way to write! What kind of EPROM programmer do you have? Quote Link to comment Share on other sites More sharing options...
flashjazzcat Posted March 17, 2015 Share Posted March 17, 2015 EasyPro 90B. I saw a photo of an Indus board with a 2732 sitting in a 28 pin socket. I assume this would take a 2764 with two copies of the OS on it. Not sure what Brenski's drive has, though. Quote Link to comment Share on other sites More sharing options...
MrMartian Posted March 17, 2015 Share Posted March 17, 2015 (edited) Huh... If you're interested, a Minipro TL866CS (like: http://www.ebay.co.uk/itm/High-speed-TL866CS-USB-Universal-Programmer-EPROM-FLASH-AVR-TL866-Programm-/190884393222?pt=LH_DefaultDomain_3&hash=item2c7198b106 ) is pretty cheap and programs quite a few devices.. At the same time, yes I do believe that the Indus drive had room for a 28 pin socket, but came with a 24 pin. If the OP is up for some soldering work, that may be an option...

Binarygeek Posted March 20, 2015 Share Posted March 20, 2015 is there a "serial number" thread for these? Not sure how big the Indus OS is. Anyone? Indus stock and upgrade are 4K 24 pin ROMs. Gotta be careful about substituting a ROM with an EPROM in the 1050. You will have jumpers one and three closed and jumpers 2 and 4 open for a ROM chip; Jumpers 2 and 4 closed and 1-3 open if an EPROM is present. If you switch the ROM with an EPROM and don't set the jumpers, you drive will appear dead. While you are inside the Indus drive, press firmly on all socketed chips in case one needs to be reseated. Good luck. Quote Link to comment Share on other sites More sharing options...

All the Indus drives I have seen, (and I have seen quite a few), have a 2732 EPROM. I have never seen a mask ROM in one. Quote Link to comment Share on other sites More sharing options...
flashjazzcat Posted March 23, 2015 Share Posted March 23, 2015 That would explain the lack of jumpers. Quote Link to comment Share on other sites More sharing options...
