Hello, my fellow Oricians! :) I'm very happy to share our newly developed hardware extension for Oric: The Oricart ! The story : Before couple of months @ rax asked me if it would be possible to create something simple for our Oric games which acts like cartridge... then we started to dream and to a...

We are on weekend .. And it's a long week-end .. due to easter .. Indeed! Well, I'm trying my best to make good looking video clips - unfortunately it takes more time than to create another hardware :). Anyway, as promised there will be release - just don't be too 'censorious' to the quality of vid...

It's not because of April fools day - It's real!
And what is it? - The answer will be demonstrated this weekend in new thread!

! Whatever V1.00 or V1.1 is loaded, menu is "cut"

Thanks, @coco.oric!

Attached version 1.20 contains:
- real fix for the menu;
- euphoric compatible.

Well, new ver.1.10 is available:
- Oric-1 and Atmos (Pravetz-8D) compatible;
- first time menu is fixed (thanks to @jbperin for feedback ).

I'm attaching the fixed file here and @rax will update his first post.

EDIT: see next posts for an "more" updated version .

You can play with different values HERE .

Before: After with 100 Ohms: IMHO with 100 Ohms the sound will be too low, but this is individual and depend on how much you want to decrease the volume.

Do these have the same problem? I think recorded with different settings. IMO these are OK. Attached are both in DSK, I've started randomly some games and they worked. Can ClkSignal resave the file content to a DSK? Like put the HFE as "A" and use sedoric copy function to "B" ? ...

Exactly! This is really strange. As far I know @ThomH don't use the HxC library code but his own implementation.

I played a bit with the file and by converting it seams to be an error at track 3 side 0: libhxcfe version : 2.13.2.2 Input file : swd7.hfe Output file : swd7.raw Checking swd7.hfe File loader found : HXC_HFE (SD Card HxCFE HFE file Loader) Loading swd7.hfe file loader found! Write RAW file swd7.raw...

This is great that you was able to produce HFE file! We can expect lot interesting stuff from you @SteveM ;). If you want to upload it here at DF forum - you can compress it to ZIP and then upload work fine. You can use your file with Gotek and with the other floppy emulator. Here I've described alr...

No, Oricutron doesn't support HFE file format at all, so far.

Indeed! Congrats that you made it and good luck!

@mmu_man: Yes, you are right about >1000. I wrote about this detail 2 years ago - HERE .

According to the schematics the expected max. voltage should be around: 5V*(1/23) = 217mV (peak-to-peak) which is really low for standard "Line level" . You can do some experiments - replacing R13 (1k) with bigger value (i.e. 4k7, 10k, etc.) and see the effect. At-least there is no risk to...

... erase CHIP M27128A .... What type and model exactly is your chip? If it's such one M27128A - it's UV EPROM . The UV EPROMS can NOT be erased with any programmer you need UV lamp ERASER. Else I have the TL866 programmer, Mac and bunch of UV chips but I never tried to play with this configuration...
