Well it will do something when the machine is powered on because the Srams are powered by the PSU's +5.
I recently bought and repaired a Expert HD but I assume the battery is still in the same place as the Expert II.

I'm not sure how to attach pics but on mine there is a little diode next to the battery labeled D209. Get your multimeter and make sure you are getting 3 volts to and after the diode.
You should be able to access the battery withe the side removed from the machine.

although I haven't a clue what I'm doing in the game, it boots just fine with the FDX68

Thank you, so i must review or speed in some way my code, since i lost quite always the eject signal with this game!

Hi,

@Golga not yet.
Looking at PCB pictures on the Internet it seems that maybe only 1 +positive pin is connected (maybe they are joined underneath on the otherside if the PCB?).
I might have soldered the + battery terminal to a non connected pin?

I think I need to take out the lower PCB and investigate.

It is strange how the text has got larger? So SRAM_CLR did do something.

I have passed all but 'Main' on memory test MTEST (text, graphics, sprite and system). I don't know how to unload module to allow this test to run.

Have you checked you have power to the Nvram(s) when powered off?

Time for the 3rd Farland Story game. Hope you guys enjoy the video!

Hi,

I thought I had successfully fixed an Expert 2 (fitted PicoPSU and coin cell battery for SRAM).

But when I went to setup SASI with Bootset and Switch I could not save settings.

The original SRAM showed 8mb, I only have standard 2mb. I used SRAM_CLR (CLR and CLEAR commands) and now the Command text when booting is larger!?! And I still can't save. So it looks like the SRAM has been erased.

Switch now shows 1mb and SASI driver location ED0100 is in RAM not ROM, I can't seem to install it to ROM.

Are my SRAM chips dead?

Does anyone know about the SRAMLOAD.Lzh programs? Can I write to SRAM a saved .DAT from another X68000/Emulator? SRAMSAVE.R generates a .DAT file.

I can boot and play R-Type and the computer seems fine (gfx and sound)

I've also modified Master Disk V2 with SRAM tools and Memory Test, I had to delete RESTORE.x to gain space.
It is nicer to have a setup and diagnostic disk all-in-one.

Thanks

8bitdo have released a wireless/BT N64 controller mod kit with a hall effect joystick for those interested, stick can be purchased separately.

I added the model for a 3d printed case:



so far, i still can't Tunnels&Trolls, could someone with FDX68 confirm TnT works with it? 

Image is nearly ready, made some last minute fixes yesterday and will upload soon.

This is a 2gb partition, and has most of the tools you'll need. The common ones are there. Disk format tools are there, I even made batch scripts to make the format process super easy. Have some SX-Window stuff in there too.

As for demoscene content... not sure what you're looking for specifically but reach out to me separately for any requests/etc. I should make a new post when I share my image. There's a lot of content not in the other combined images, with some space left for more.
