This incredibly useful website for the Acorn System series appears to be down. Does anyone know the author?

I keep meaning to download the whole site and now wish I'd done it!

Hi All

Just spotted this post and can confirm that its not working, don't know why ? Its hosted by TSOHost ?

I'll leave it till tomorrow and see if it comes back before trying to contact them.

In the mean time you should be able to access a copy on my Raspberry Pi here http://81.174.146.201:8080/acorn/index.html.

I've just about finished a complete refresh of the website which I plan to upload next month.

Chris

Thanks Chris, anightin,

Glad to hear its still being updated - great site and thanks! Am I ok to take a big wget from your PI? I'd like a copy here anyway as I'm often on your site and one big get might stop me from repeatedly opening the PDFs direct - if not no worries.

Thanks again

D

Looks like its back up so just a hiccup from the hosting co ?

I'm happy for copies of the info to be taken off the site, don't want it to get lost though I've no intention of closing it any time soon.

I would be interested to know how well the RPi works as I'm thinking of ditching the host co next year as its costs more per year then an RPi !

Your site is mostly HTML and images, so the Raspberry Pi performs great. If I didn't know that it was on a Pi then I wouldn't have noticed it.

Thanks all, I've downloaded the site now!

I've been playing with my System 5ish machine yesterday and got it talking to NoIce debugger. Today I'm going to make a start on a video card. I'm going to go a bit left-field though and use an EF9345P for no better reason than I've got one and want to see what it's like!

Without your site I'd be lost!

There is an Atom VDU board based on the EF9345: https://site.acornatom.nl/hardware/vide ... lomskaart/ (switch to English in the right upper corner).
There is also a lot of software in the archives for this board (e.g. https://acornatom.nl/atomarch/an92-05/) . Since System5 and the Atom have a lot in common this should be a nice starting point. As a matter of fact, I have a few spare boards left.

I'd not spotted that so thankyou - an good starting point!

Where does the card appear in the memory map?

Would you be interested in selling one of your boards?

The main site is still falling over when I try to access the System 5 pdfs so I'm not sure it's 100% fixed

The EF9543 at #BE20 - #BE2F, the video RAM is not mapped into the memory map so that is not directly accessible by the CPU.

There are a few interesting boards on your site that I feel need emulating, such as the video, DOS, and Z80 boards. Are the ROMs available for the DOS and Z80?

Somewhere in my archives there's a ROM image (and the sources of) GDOS. E.g. https://site.acornatom.nl/atomarch/Pc97 ... Gdos15.src This file has a 16 byte header at the start. For the rest it's just an Atom assembler file.

I don't have any ROMS or software for the Z80 board. I'll give it a try to get it since I know somebody who still has such a board operational.

Thanks, that's even more of a reason to get it emulated to ensure the ROM is not lost.

I contacted Theo, who has an Atom Z80 board with CP/M still up and running. He will send me an EPROM for the board and some discs with software.

I have received an EPROM with the label CP/M kaart on it, so this must be the BIOS for the Z80 board.

I also received a bunch of 3.5" discs with Atom CP/M software. They should be formatted in AtomDOS format. I have to work out a way to convert them to images.

Thanks, I'll see what I can do with it over the next few days. The floppy images will be crucial to be able to boot the system.
