Enterprise 128. SDRam port to MiST by Slingshot

[rondc]

Hi folks !

It is very nice to announce that slingshot a.k.a "gyurco", has ported to SDRam (for the MiST fpga ) the Enterprise 128 core that has been implemented by Kyp and the RetroWiki fpga-DEV team. Of course with the help of the hobbyst of the Hungarian community of enterpriseforever.com

Here are the MiST and SiDi versions of the Enterprise 128 core , with the invaluable help of slingshot.
I guess the sources are being published on the git by kyp

To enjoy it you can now download the first test versions.: ( feedback is welcome )

Thank you! I'll test it in both boards!

Thank you to all for this new core, very appreciated

Also in mist-binaries:

I wonder if it would worth to add floppy support, as I didn't found floppy images. However, as EXDOS uses FAT12 as filesystem, it would be very easy to create image files with Hatari's zip2st tool (basically the same image format can be used as for Atari ST, and the FDC chip is identical).

Test done on MiST

I've been able to load EP128.VHD (dowloaded from https://szergitata.blog.hu/2015/05/04/e ... t_guide_uk), and play some games .

Joystick swap if possible will be welcome

What I've seen is that my monitor says "Video Input - Out Of Range" and I can't solve it . I have a MultiSync EA190M 19" I only have the same problem using 128 Timings in the Spectrum core. With the TVC Videoton core (a very close computer) I don't have any input signal issues.

Thanks again!

Thanks for your work! Here you find some disk images: https://enterpriseforever.com/downloads ... emezei.rar
And even more: https://enterpriseforever.com/downloads ... F%5BIMG%5D
Most of them are standard 720kB .img files, but there exist some non-standard (i.e. 820kB-sized) as well.
A lot of 800kB disk images (that format was the "de facto" standard of that time, 80 tracks and 10 sectors/track), at the middle of the page:
http://www.ep128.hu/Ep_Emulator.htm
The reason is that the EXDOS-card was well-configurable, and with WD-1772 controller chip you could format floppies over 80 tracks (90 was the upper limit, if your FDD supported this), and divide a track into 10 or 11 sectors in case of DD disks instead of the standard 9.

Who can explain me how to use the files linked up ?
I have donwloaded some img and vhd files, I load it from menu, reset, but every command I give from the basic haven't effect:

:f:
:dir
:file

Ok, I understood everything, sorry

I tested some enteprise games and demos, I didn't know about this computer, but I think it's better than Amstrad CPC.
Happy now there is a core for MiST. It lacks some option like joystick swap but thank you so much to Slingshot for the port

I've checked on Sidi, and I don't have the "Video Input - Out Of Range" error that it happens to MiST, so something must be fixed... I'm using the same monitor.
