Quote from: dragon

Mother x4 connector destroy the pins of addon boards connectors,because they not fitt togeder well [...] It happend If you not have the cpc mounted, and you are continously mount/unmount the cards. The two connector fit to hard. So you make force, and at some time the pins of the addonboard left out the connector. I have to use a screwdriver all time to put the pins back every time i use it

You know, I have an email (and PM) and promptly answer about my CPC expansions boards (in english, french and spanish). I'm not dead, just not here. (except now, to confirm the rule)
The cause to your problem is into your answer... You don't use them in a "normal way" and forcing is never a solution to a problem.
Because you plug/unplug many times the boards, the pins should bend a bit and are no more properly aligned to the MotherX4 female connector.
A way to fix that is to use a ribbon cable with a 50 pin female connector with key (not whisky) and plug/unplug some times to straighten the board pins... (your welcome)

I had noticed the same problem myself, but it didn't register as a design fault. I've seen tight connectors before, so I'm just extra careful.

Back to the 4 MB RAM expansion...

Does is work in the way of addressing 8x 512 KB (each 512 KB block using &7Fxx, &7Exx... &78xx) or is it a different design?

How much will one card cost approximately?

Is it compatible to CP/M Plus?

Cool idea! Then unban all banned guys and girls and start from scratch.

Oh, imagine that, what a surprise, the world is going upside down!

Seriously, cut it. This is a formal warning.

I really would like to talk about the 4 MB RAM expansion now...

Piotr · « **Reply #34 on:** 21:30, 26 October 17 »

In meantime, 4Mb second prototype board with CPC 464 and DDI3 , 4mb demo running ,

https://www.youtube.com/watch?v=l5vBcsPKqCA

With 6128 working too.

wils_2k · « **Reply #35 on:** 22:32, 26 October 17 »

That's great, Piotr! Are you planning on building it into the DDI3 or keeping a completely separate board?

Ygdrazil · « **Reply #36 on:** 01:57, 27 October 17 »

Girls!

Currently the male to female ratio is 62:1.

With a current total of 1856 members means that Zoe has approx 29 CPC fellow girls on this site!

Regards,
Ygdrazil

Wonderful! Thanks for making great hardware and thanks to Devilmarkus for the first ever 4 MB demo on Amstrad CPC.

This hardware is exactly what we need for advanced OS on CPC!

Piotr · « **Reply #38 on:** 17:47, 29 October 17 »

For DDI3 i do add on board . Also, more tests, i still use X-mem as rombox but change this is also in progress.

Wow again... another attack...

Come on Bryce. I read your threads and posts and they are usually very good. I have not 'yet' bought any hardware from you and who knows one day it could be if you make some for sale. Piotr I have bought and so far also had service above and beyond what was expected - he even sent me replacement parts that I ordered incorrectly myself at his expense. I cannot say many people do that and for that reason I would more than gladly buy from Piotr again. Why does every hardware person who makes an awesome piece of hardware not up to highest level on the 'Bryce Scale' (pun intended) get bad flack from you? Yes, every company no matter who that makes products has a certain percentage faulty, every company no matter who that makes or sells products/servers has some customers with bad experience... Do you know how many dozens, hundreds, thousands of hardware that Piotr has sold to make a judgement that he offers a bad product / service overall? I can't make that judgement other than so far what I have bought and the service I have gotten... First class both!

Post more info on the 4mb expansion please... does it have the hardware conflict and can it work in one MX4 slot in the JustCPC128k?

Well, if you ask me (you didn't but anyhow

) basically all you can say is that you had good service from him. Good for you, really. But Bryce never speaks without evidence and he's been exhaustive in his research and analysis (if you'll recall...). And of course, he's not against everyone making something - in fact he's not against anyone; but when trouble appears, I think he's doing a service to the community to draw our attention to it.

zhulien · « **Reply #41 on:** 13:03, 30 October 17 »

Actually, my latest purchase from him was today. I have purchased about 7 or 8 items from him so far without issues from sellmyretro. And of course a couple of dozen items from CentPourCent before he was blasted away... sadly. In addition to buying most 6128 Pluses I could get my hands on from ebay.uk... but that's another story as my developers needed machines to work on. I have 3 gfx cards waiting to arrive too, hope they do. Several M4 boards etc... All I can say, is all who I have bought from including Piotr has given me fantastic service NO EXCEPTION.

Gryzor · « **Reply #42 on:** 13:07, 30 October 17 »

And, as I said, good for you.

I am glad you had such a positive experience with Piotrs hardware. However, my experience was completely different, and I wasn't alone. I am the first to praise great hardware and service, but I am also entitled to express my opinion when the hardware or service is not a good experience, by my or anyone else's scale.

Bryce.

Just your opinion, the one of some (very few) other who have been banned and (some) came back with a new nick. You are better on the other forum, you have been there mainly for attacking the cpcwiki. Make your web site or go see a shrink.

Oh, I had forgotten that incident, that was a funny one admittedly

Still, as much as others provoke or whatever, do refrain from characterisations... never ends well!

As a complete newbie on here (and on the scene in general) and because I've no experiences good or bad when it comes to buying hardware from people, all I can say is that I'm really looking forward to receiving the DDI3 my wife bought for me from Piotr's SMR listing this week.

Abandonware is just an opinion of many... it isn't a law... in fact the law here in Australia, and many other countries in the World there is no releasing of copyright due to software (or any other media) being abandoned. I was stating a fact that cpcwiki condones piracy - I don't think anyone here can deny it. Piracy is piracy. For the record, I choose to buy my software because I like the shiny packaging it comes with. I couldn't give a **** about a company losing revenue because someone else pirates their software... follow the laws of the land and all will be sweet. Just because I don't give a **** about companies revenue doesn't mean I don't buy products - in fact the opposite, if they make a product I want or like... I will buy it if I can afford it, and usually live without if I cannot. Simple.

My experience with Piotr.

Before buy all the questions answered. After the money gone none of the questions I did was answered. Three or maybe four important messages to me.

Once and for all.

People should know they could be the next.
