FM Towns Marty 2/4MB RAM expansion card reproduction

If you are trying to run Alltynex from CD-ROM on your Marty you will fail, you cannot.If you want to play Alltynex on Marty you must launch it from hard disk, my upcoming SCSI card will allow this.

I built this Marty-compatible self-booting disc image. Aside from the expected performance issues, the only other problem is inability to save scores (no HDD install).

In any event, SCSI card is still amazing 🙂
 
Is there a list of games that the RAM expansion enables, aside from SSF2? The compatibility list shows which games don’t work on a Marty with vanilla accessories, but that doesn’t take into account Caius’ RAM expasion, a future SCSI adapter that could enable HDD installs, etc.
 
Thanks for review!Just a little point out.The cards adds addtional 2MB to the exisistig 2MB of the Marty.On the bottom side of the card there are other four 512KB RAM chips (so other 2MB) but I never populated them to see if it actually adds further 2MB (so 4MB in total) .So, this card is tested as a 2MB RAM expansion :)

Haha, oh boy... noob mistake :unsure:

Thanks for the great device! Love it.
 
The first batch of 20 units has been sold out very quickly, thanks for your interest :thumbup: A new batch will be available for sale in a couple weeks.
 
Only one Marty 2MB RAM expansion card left in stock on my Tindie store, snipe it before it's too late! :)
 
Has anyone ever created a 3D printed case for the RAM Expansion yet? I recently purchased one of the RAM boards, but I don't like the idea of leaving the bare unprotected board plugged into my Marty.

i still plan on making one but my Marty died (frozen boot screen) before I could even install the expansion module. They aren't cheap, so I'm waiting for a step-by-step help from a very knowledgeable maker. He's a busy guy, so I'm taking whatever time he can give to help.

Does it just need a recap or what?
 
I have started creating a case for the memory expansion. I have the footprint done with countersunk screw holes coming up through the bottom. I just need to finishing tightening up around the hole for the connector and then make the snap on lid. I will upload when finished. I hated leaving it bare behind the Marty lol.

Very good job.How do you think to handle the ON/OFF switch?

Plan is to have a large plastic slide switch with a little hole for the real switch to go into, this would protrude through the lid to allow to slide on/off. I’m having fun learning - this is the first 3D print I have designed myself from the ground up.

Ok the main box is complete. Nice tight fit around the connector. Everything is so carefully dialed in that I can probably remove the recessed screw holes entirely because it’s a very nice friction fit. I also increased the thickness of the base so that it sits flat on the shelf behind the Marty without putting any downward strain on the connector (though I accidentally made the extension a fraction smaller but that visible line has already been fixed). The top is almost done, but creating the slide switch to integrate with the top will be tricky.
