Wanted / Re: SD card interface
« on: 2019.May.19. 13:37:52 »
Yes - he does this in his spare time so it can take a long time. But it's worth the long wait, because the SD interface is great.

And the good news is that the new SD boards can also have a real time clock. And also FAT16 support is coming in the future too.

The Spectrum version of R-Type was absolutely brilliant. But this CPC remake is even more amazing!!

Fantastic to have it on the Enterprise as well. :smt041

Not yet, they are a mess of files from various programs all mixed together, so not really usable currently. A long-term project for Zozo...

I see... I'm happy to help sort through stuff if Zozo wants any help.

Wow, that's a load of great information!

Are the source codes downloadable anywhere? I couldn't find them in the thread but maybe I missed something as there's so much there.

Good idea about EPower, although I think I don't really want to replace everything. The 5V is working fine.

Do you need your spare coils, or would you be able to send me one? It would be great if I could fix it.

Very interesting. Where did these IS documents come from?

Thanks for the tip, Pear. I'll get some 0.25mm enamel wire and give it a go myself.

Is there any way to confirm whether it is the coil that is causing the problem? Could it be another component that is causing the short?

Hardware / Broken 12V
« on: 2019.March.17. 18:41:19 »
Last weekend, I started having problems with my Enterprise 64 and I realised there were problems with the 12V circuit. Thanks to previous posts on Enterprise Forever, I discovered the most common fault is with TR2 and C9. So I replaced them both and it started working again. I thought this had fixed the problem.

However, yesterday I plugged in the Enterprise and disaster happened! Smoke came from the case and TR2 was completely melted, and the wire to coil L1 had broken as well. :cry:

Thankfully the rest of the computer seems to work if I wire in an external 12V source... so it's only the 12v circuit that's blown. That is a big relief!

Anyway, I replaced TR2 and C9 again and patched the wire to coil L1, but when I tried power it up - more smoke started coming from TR2, so I unplugged it quick. I think TR2 must be short circuited somehow. Looking at the schematics and using my very limited grasp on electronics, I guess the culprits are going to be C10, TR3 or the coil L1. Does anyone know how I might narrow this down? I have a multimeter but don't have access to an oscilloscope. Is it even possible to get a replacement coil???

All help gratefully received. :(

Thank you! :)

Programming / FILE program
« on: 2019.February.17. 12:43:30 »
I really like the FILE program that comes with the SD interface. I wondered if I could request an added feature?

At the moment if you select a drive that doesn't exist (like C:) then you get a Retry/Abort and then the program quits.
I was wondering if it would be possible to just display a blank screen, so that then you could get a chance to select another drive.

Is the source code available for this program? ;-)

Programming / Re: EXDOS 3.0

No, but on a Z80 card also running at 4MHz in an original IBM PC, and all from floppy disks.

The way things used to be!!!

Was that how EXOS and IS-BASIC were written as well?

lgb hacked his emulator so we could run the Z80 assembler and linker on a modern PC :mrgreen:

Did I understand that right? Are you compiling the sources on a modified Enterprise emulator? Does that mean the original was actually compiled on an Enterprise?

Programming / Re: EXDOS 3.0
« on: 2019.February.16. 17:18:48 »
Amazing news!  And several unexpected bonuses...

No “bytes free” delay on floppy disks and small/medium volumes

Really looking forward to the release. Thank you! :mrgreen:

P.S. I didn't realise that you had access to the original EXDOS 1.3 sources...

IstvanV's wonderful ep128emu package also has an image converter utility that works almost miracles.

Wow, brilliant! Thank you!

Just wondering if there was any news on this exciting project?
