Thanks a million!
Where did you get the actual schematic? Looks like you scanned it from somewhere.
I guess it makes sense that my "option 0" didn't come with a "thru" cartridge connector, because mine is badly soldered to the board.
I never received a floppy disk, but was sent a folder full of files which is supposed to be the contents of the disk. I haven't really taken the time to look closely at those (cryptically named) files, but I'm doing that now....
explains how to add the clock option, but as I understand that this is just a battery-backed version of the internal Atari ST clock and not something related to the Discovery features I don't thinkl I need it (I have a MegaSTe which already has a battery-backed clock).
which is decribed as "documentation revision 2.7
" says that it describes how to modify the board so that it can accept more cartridges in the second cartridge port and how to add extra ROMs.
I haven't had the time to read through it in detail, but to me it sounds like I really need to add an extra switch, according to the docs, if I want to be able to use the "thru" connector for additional devices. So the previous owner really had no use for the cartridge connector he soldered on the board as the HART chip has to be switched off in order to access it?
I don't really understand what the ROM sockets are for. SPECTRE and Mac ROMs are mentioned, so I suppose this part of the Discovery is meant to emulate an (ancient) Mac computer?
If that's the case I don't see any need for that as I already have a (new) Mac. But if the ROM sockets can be used for other things I might be interested.
I'm also very interested in making the "thru" cartridge connector work as I need that for my project (recasing the MegaSTe which includes a chain of 3 different MIDI related cartridge devices with the Discovery at the end, and the "thru" cartridge at the very end for any additional cartridges).
If you know what the Discovery options are for, could you please summarize and explain as the documentation files I've found so far seem to go into very much detail, but doesn't explain it in general?
