Recommended Posts

Does anyone know the part number, ID number for the Indus GT O/S chip?  Where to source?  I cannot find the schematics.

In an earlier discussion, someone stated that the upgrade ROM from Best disables CP/M compatibility.  

 

I have the ROM in my Indus and I thought CP/M still worked, but I plan to test this when I have finished hacking the 520STFM on my bench.

Interesting.  The new features sound nice, but there's no way I'd give up CP/M, it's the only reason I still have the drive connected.

Hmm, could probably use some kind of 2764 to 2732 adapter and have both OS's selectable by toggle switch.

to the best of my knowledge I haven't read of their rom disabling CPM.  It isn't a custom ROM, it is a 'hacked' rom, adjusting a few 'configuration' values....  primarily the excessive idle spinning.

 

It is just a standard EPROM.  If you know anyone who can burn an EPROM for you, there are different versions of the ROM on the net.... including either the Best Electronics one, or a similar adjusted ROM, along with a totally custom rom by @MrMartian which gives US Doubler speeds and such to the drive.  I believe his does eliminate CP/M from working though.
