ORIC SDCARD

This is the right place to discuss on how to implement hardware vsync, adding a VIA or AY chipset, puting multiple roms, or how to design a new flash expansion card.

I was thinking on a patched ROM that trapped the CLOAD command and could read a tap file on a sedoric disk.

Seems doable?
I suspect the problem would be that some TAP files will use page 4, or RAM locations used by the Sedoric system.
Certainly doable, but the loaded programs might crash the system (or the system crash the program).

In my project, the RAM overlay is not available. I don't now how Sedoric works but if it is not writing in the RAM overlay for its management, I can store it in the bank 1 for example. The first CLOAD instruction will make appear the window to choose a TAP file or a disc. When a disc must be swapped after we can use a secret key code like FUNCT CTRL to show the window again with DSK files but without TAP files.

Since you have freebanks, you could probably have both the Oric 1 and Oric Atmos versions of the ROM and allow the user to boot in Oric 1 or Oric Atmos mode, and have the games flagged as compatible with specific versions of the ROM, would make Atmos users allow to play Oric 1 games, and Oric 1 (or Telestrat?) users to play Atmos only games :)
This is doable with a small switch on the pcb to force the computer to start in ORIC-1 mode or with a routine called with a pre-programmed "!" vector.

For using a better compatible gerber file, I have updated the DIY link. :wink:

Just a quick note. In the Spanish forum Retrowiki, a user just launched a batch of 15 cards with components with the info Kenneth provided and all of them were reserved in a few hours. I even missed it!

I just can't believe the price is under 8 euros! (unmounted) but the list was complete even before knowing it.

I would be interested in one, if it was fully built, tested and ready to use: My ability to solder things has led to the destruction of many pieces of hardware, so now I try to avoid that :)

Interested, too, same as Dbug.
Depends a bit on the price + shipping cost too, if you already have an idea?

It will be fully tested and I'm sure I can do a good price for this group. Havn't worked out the price yet but will be somewhere between £20 to £25 plus postage. Will work out when I get time later.

Good, i'm interested in 2 if possible. At least one.
Could be solded or not and the 3d printed case is a very good idea

This looks good! Couple of questions though, unless I've missed the information somewhere is this a read only device or can it write back? Reason for asking is that on some TAP adventure games allow you to save where you got to so can this do it? Secondly is this unit accept TAP and DSK files?
