A couple of things. Firstly, I noticed that my Mini-Pro could only read SOME of the 2716's I had, not all of them. So, just because it read as zeros might not mean it really is.
Secondly, there is a 2K bit Altos-related ROM available at http://toastytech.com/files/ancientroms.html There is a link to a zip file. Look for the one labeled ALTOS.ROM in the zip file - is is the right size (2K Bits). It is "Monitor Version 6.05" - but it looks like is for a system that could have a hard disk. I have an Altos 8000-2 (double density) that I just acquired off eBay that is in a similar state - no floppy activity, nothing on the terminal. But I was able to dump its rom with an 8K Bytesaver - haven't disassembled it yet. If you weren't aware, Doc on the 8000 series is available at http://www.bitsavers.org/pdf/altos . But I don't think it covers the 8500. JRJ On 6/21/2015 10:43 AM, Chris Osborn wrote: > Thanks to Josh Dersch I now have a good copy of the ROM for the Altos 8500 > boards.
