Real Time Clock Board

[dirtybb]

Hi there,


To people interested in the CPC RTC, I received a request for 2 more boards via PM so I think we're at something like 8, I'll start a 10 pieces batch. Expect a delay of at least 1 month, payments will be requested once the boards are made or at least components are ordered.
Watch your PM's.


Best CPC regards
Thierry

Great     
Thanks !

Awesome news. I did see yesterday that the rtc rom corrupts fw3.15 mode 2 startup screen, and that it breaks the hxc v3 app from either autoboot hfe or rom. Will test further and confirm later.

Now that i can test my X-Mem, i can confirm the problem, and it's quite major, especially for the HxC...

Indeed. Hopefully fixable

For this case you have the jumpers on the RTC board. When using it together with the X-MEM then you set the jumpers and that's it. (Without the jumpers set the RTC runs all alone fine). Just look at the instruction manual of the RTC.

No


The problem, as CraigsBar stated in his post too, happens also when the RTC is in EXT mode with the RTC rom flashed on the XMEM (at slot 12 for me).


If the RTC is plugged, then HXC Manager hangs, if it's not plugged, it works ok. See the screenshot of Craigsbar.

That's not a problem of the RTC. Simply disable the Time-ROM and FW 3.1x and HxC shall run.

However the Time-ROM was there before, FW 3.x and HxC manager came later, they should be adapted.


If I understand right, then for FW 3.x there is a bit of the watch to see on the screen, ok, that shouldn't bother much if this is the only problem.

About the HxC software, I never got it really running from ROM anyway, it works only from a DSK, so I can't really talk about it. But obviously it still has some bugs in the ROM version, which tries to crash my 3" disc.

ERM. The same happens when launching the hxc manager from disc BTW. So it's not just the ROM.

Well, in my case it is like I described. You seem to have an additional factor, or we are not completely on the same page. [nb]Frog protection you know?[/nb]

But to end this discussion: Ok, so some ROMs are incompatible, that's nothing new. So one can use commands like !ROMON or !ROMOFF to select the desired ROMs and everything is good.


What's the alternative anyway? There is no other RTC with support for BASIC, CP/M, FutureOS and even SymbOS.

I agree with you, but was hoping there can be a software patch. You're right that it might be easier on the HXC Manager side.

Well, we have the source. And there could be a software patch. Just need somebody who can look at it. In this case it would be nice to have the source of the other two 'problem' ROMs too. If somebody volunteers please PM me. Sadly I have nearly no time at the moment.

Hy, iam interested in one board too!
So if there is a chance for one, please sign me in.
Or should i write a PM?

Thanks so much for the Work.

My original Dobbertin Timerom is dead for about 10 years, so a replacement would be perfect

Hi, I just received the last missing parts for the 10pcs batch so it should be fine. No need to PM I'll get back to you when they're ready.
This one should last much longer considering the battery is user serviceable.

[Tolkin]

I am so nervous about... Future OS will have the correct time then.
Really nice

The new installer allows you to select the ROM number of the RTC. This number depends on the jumpers on the board.

Hi there,

I finished building the 10 cards, I sent PM's to interested people, if you like to have one too please send me a PM!

[TFM]

The great RTC arrived! Thank you very much! 

[Tolkin]

Puh, it ist 22:30 here, find the Package on my Desk, a few seconds ago.
It arrived, package fine... so eat sth. and play a little bit with the clock
Thanks so much!

Hi,
the CPC RTC board arrived a few days ago. dxs, you did a great work with Y2K patch and the mod for battery use. Thank you very much. 
I have tested it already under BASIC and together with my Inicron ROM-RAM-Box. It works like a charme and the board looks very professional designed and soldered.
At last yesterday I had time to test the board with CP/M Plus. Time and Date for all files is marvellous. (Thanks to TFM for the TIMEROM#.COM patch)

Best regards

Hy, played with the RTC yesterday until 4:00 in the morning.
Never thought that it is making so much fun with a "clock".
If you build another batch, you can count me in again for my 6128plus Setup.
Thank you so much!
And TFM too, of course!

[dxs]

Thanks to everybody for the kind words, I really appreciate it! I got some valuable input and help from a few people, especially TFM, Gerald and TotO.
BTW @Tolkin if you like you can have another one right now, I was keeping a spare in case something would happen during shipping... Just PM me if needed!

Hello

I would like one of your Real Time Clock Boards if you have any left please.

I just found out that it's no more possible to play Fruity Frank on my 664 when the RTC is connected. Intro screen works (a first little glitch is visible while the intro screen is drawn) but entering the game results in a black screen (lockup). Tested with X-MEM FW 3.15. Booting with CPC BASIC ROM (I never start in MODE 2 basic, this disturbs CPC-RTC boot screen and disk menus)

My tests have shown almost the same result (graphical glitches may look different) on following setups:
- CPC 664 + CPC-RTC + X-MEM
- CPC 664 + CPC-RTC w/o X-MEM
- CPC 6128 + CPC-RTC + X-MEM
- CPC 6128 + CPC-RTC w/o X-MEM

So it seems there is incompatibility to be expected when RTC ROM is placed in X-MEM.

For a quick look I would guess that your power supply could be to weak.


Can you upload a DSK of the game you used, then I can test this and mabybe confirm and try to find out what's going on.

[Poliander]

I'm using an additional external PSU (Conrad/VoltCraft SPS 15-36W). The game DSK can be obtained here
