Quote from: Animalgril987 on 01:03, 23 March 21Hi Noel.The MX4 compatible backplane has a separate supply from the CPC, and I only have the RAM expansion and Duke's M4 plugged in.
Quote from: Audronic on 06:10, 10 April 21Hi NoelJust burned a Version 1.01L Eprom for the Lower Rom BoardIt works well in the CPC464 with the exception that in the CPC6128 it thinks the Machine is a 464 and the Keyboard layout reflects that.Apart from that it seems to work wellThanks for all your good workKeep SafeRay
Quote from: llopis on 11:02, 10 April 21The detection of the model has been fixed (should be ready in the next release tomorrow probably). The problem is that it shows CPC 464 instead of "It's a CPC but I have no idea which model it is" because the only reliable way I know of detecting the model is looking at the lower system ROM (which is not accessible if you're using a low rom board).
Quote from: gerald on 11:57, 10 April 21For poeple using the XMEM for overriding the lower ROM, you might just ask to re-enable the internal ROM after copying the code in available RAM (ie after checking it).Then you could test the internal lowerROM.
Quote from: llopis on 12:56, 10 April 21Oooh, I didn't know you could do that with XMem. I'm already doing it with the Dandanator and the M4. Could you point me in the direction of the simplest way to re-enable the internal ROM and disable it again for the XMem? Thanks!
Quote from: CraigsBar on 16:12, 26 April 21I see on the Github a fix for Crash in the DSK version from 19 days ago. Any idea when this will be released as I currently have a new Tall Key CPC 464 that I want to give the a once over and the DSK woudl be be better w3ay of loading it. The version in releases however crashes
Quote from: llopis on 16:21, 26 April 21Argh, yes! :-) I kept waiting to fix one thing... and then I got busy. I'll release a version tonight. Sorry for the delay.
Quote from: CraigsBar on 22:02, 26 April 21Awesome news, thanks. This tool is amazing and I am now using it on most machines. But it is easier to use the disc version I find than openeing machines and swapping the lower rom
Quote from: llopis on 10:30, 27 April 21Glad to hear! I plan to keep updating it, so if you have some suggestions of things to check, let me know. Especially now that I have a new main menu and status screen, there's a lot more room for other diagnostics (the problem is starting to be fitting it in the 16KB ROM!).New release is up by the way: https://github.com/llopis/amstrad-diagnostics/releases
Quote from: CraigsBar on 11:14, 27 April 21<snip>Next test: I'll get the CDT and load that and see if this has the same issues with no disc interface fitted.
Quote from: CraigsBar on 11:14, 27 April 21Yep, grabbed it and tested this morning. Yay the full 512kb in the Expansions is OK Interestingly it reports the CPC Version on this Tall Key as GX4000/Plus on the menu screen but correctly identifies the Roms on the Rom Check. Is this a bug? or is it the "fault" of the DDI-4 expansion (that clones a DDI-1, 256k Ram and 256k Silicon disc in a single interface) from Piotr (Zaxon).OK completed this test on the tall key... and the result is "Unknown CPC"
Quote from: llopis on 11:46, 27 April 21Oh wow, that's unexpected!It attempts to detect GX4000/Plus by turning on the ASICS control registers. No normal CPC should do that, and I didn't think the DDI-4 did either, right? That's quite odd. I have a DDI-3 and I have a DDI-5 coming my way, so I can try it with those.As for the unknown CPC... that at least it's more normal. It says that if it's not a Plus model but can't make sense of the system ROM. What does it say for ROM test? Does it detect the lower ROM correctly?
Quote from: CraigsBar on 12:15, 27 April 21OK some tests done! All of these were loaded from tape. Even when the cpc had AmsDOS to ensure the exact same software was used.First 2 are taken with stock configuration, no expansions just the cpc 464 tall key.Second 2 are with the DDI-4 attached.
