That sounds like the DAC is broken. Pins 2 - 9 and 11-14 are actually inputs, so either the ASIC is setting them all to 5V (in that case the ASIC is dead), but even then, that would be the colour white, so if the DAC was working the screen should be white. So the DAC is definitely not doing what it should and the ASIC is possibly also damaged. Sounds like the computer was either connected to the wrong voltage or some connected the power the wrong way around. Either way, this isn't something that can be fixed because neither of those IC's can be obtained unless you removed them from a working Plus.

Hi evenmore,
    do you have a multimeter to check some signals? If so, you should check the pins 2 to 9 and 11 to 14 on IC115 (AMS48464 - Video DAC) to see if the ASIC is outputting a video signal.

Bryce.

Hi Bryce
I got my dad to check with the multimeter. Pins 2-9 and 11-14 all outputting 5v.
Pins 15-17 (OUTR, OUTG, OUTB) all showing 0v.
Any suggestions? Does this mean the chip is bad?
Thanks again!
Chris

Amstrad CPC hardware / Re: CPC ROM emulator using a R...

Last post by Marcone698 - Yesterday at 10:47

Hi all, thanx to matronica for this project easy to make, fot me it's work fine but i have a stupid question, I noticed that the command to start a rom (|romname) does not correspond to the name of the file or the name of the rom, sometimes you need |dk to start donkey kong or |ping to start ping pong and so, in many cases it is necessary to try and try again to find the correct word to stard a rom, is there a way to know which word/name to write to start a rom or am I doing something wrong?

I have to assume that "the knack" was Roland Perry. By rights the CPC464 should have been a catastrophe.

I'm not so sure I'd fully agree with that given that the C64 was still being produced with 64K of RAM up until the early 90s while the Speccy's and Amstrads had moved to 128k in 85 and 86.

The big selling point for the CPC464 in my opinion was the fact that you also got a monitor with it in most cases, which means it could stay in a bedroom or office without the television being hijacked. Growing up, I saw so many arguments in houses when it came to delegating time to hook up their Atari/C64/Speccy and yes, even Amstrads with modulator because they wanted to see the games in colour.

Maybe I'm biased as a 464 guy, but from what I saw, and maybe this was just a Dublin thing too, but 128k and disc drives weren't the be all and end all during the 80s.

Thanks for the update! Let me know if you want a turbo-loading version too.

Yeah, because yesterday I started creating an index, but midway through connection to the db was lost because of shitty Alibaba bots and it didn't auto-resume. I just restarted it half an hour ago but it will take several hours before it's done - assuming the same doesn't happen again.

Between this and the new GnG, the Plus is finally getting some games that show its true ability, and we only had to wait 35 years.

My first real "wow" moment was the GnG remake originally programmed by @Xifos back in 2016, if I'm not mistaken.

2018?

You could try blocking the Alibaba IP ranges and see if anyone complains (redirect to a wait page as this usually makes the bots loose interest).

It's a nightmare whack-a-mole scenario to do it yourself though.  Cloudflare as a reverse proxy is much easier and free for hobby websites.

I had found this page, wishing it had a complete list of IPs to easily block, so I dropped it... but reading your message again right now I had an idea and I asked ChatGPT to parse the pages and create a blocklist Here's the result:

Code Select Expand

<RequireAll>
    Require all granted
    Require not ip 47.74.0.0/15
    Require not ip 47.235.0.0/16
    Require not ip 47.250.0.0/16
    Require not ip 47.88.0.0/14
    Require not ip 47.56.0.0/15
    Require not ip 155.102.0.0/16
    Require not ip 163.181.0.0/16
    Require not ip 47.52.0.0/16
    Require not ip 147.139.0.0/16
    Require not ip 139.95.0.0/16
    Require not ip 72.254.0.0/16
    Require not ip 61.200.84.0/24
    Require not ip 47.89.91.0/24
    Require not ip 47.89.112.0/24
    Require not ip 111.108.151.176/28
</RequireAll>


Can't check if indeed it included them all, but I'm going to try it later on the server...

Regarding Cloudflare: I only use it as a reverse proxy for some containers of mine, wonder how easy it would be to incorporate it here... in that case, does the standard non-human checks apply? Haven't really worked with it much.

Whoopsie, indeed. Let me recreate the search cache (though it's always been wonky...)!

And now, all search is broke
