Thank you!
So, you can use welcher, welche, welches for non-countables (Stoffbezeichnungen)? I had the feeling that there should be some rule for this but I haven't found it anywhere.

Möchtest du Tee? - Ja, ich möchte welchen - Is it correct too?

Correct, but considered (slightly) colloquial.

You might want to read here on indefinite pronouns.

Are there any German members here? Do you feel the following senteces correct? I mean the last word at the end of each line (eins/welche, keinen, eine/welche):

Wir haben kein Brot. Geh und kauf eins/welche.
Möchtest du Tee? - Nein, ich trinke keinen.
Öffne das Fester! Ich brauche Luft. - Auch ich brauche eine/welche.

This is obviously a test for non-countables' pronouns. Bread, tea and air are (can be, "Brot" can be an exception if you mean a specific loaf of it) non-countables - here "Stoffbezeichnungen" -  in German that go with indefinite pronous.

Wir haben kein Brot. Geh und kauf welches. (you mean the uncountable thing, the concept)
Wir haben kein Brot. Geh und kauf eins. (You mean "one loaf of it". Could be considered colloquial)
Möchtest du Tee? - Nein, ich trinke keinen.
Öffne das Fester! Ich brauche Luft. - Auch ich brauche welche.

Wanted / Re: Enterprise Case Screws
« on: 2019.October.17. 14:54:10 »
A good trick to avoid (or at least delay) the original screws loosening their thread is:

Whenever you screw a screw in, turn it backwards until it slightly "clicks" into the thread - Only then start turning in. This makes sure you always hit the old thread and saves on the plastic threads immensely.

Also, don't tighten them as hell - there's no juice to press. ;)

Hardware / What internal RAM expansion?
« on: 2019.September.09. 16:14:48 »
What would be current options for a (moderate, 512k-1M) internal RAM expansion? I understand Saint's board is no longer available.

Thanks, Tobias

I tend to watch him as well every now and then, he produces nicely made retro videos.

Good idea, although I don't have a leftover Enti to spare....

Interface / Re: USB to Enterprise serial
« on: 2018.December.11. 12:08:00 »
Some USB/Serial dongles don't support hardware handshake lines at all, some do RTS/CTS, some very sophisticated ones even support DSR/DTR. For those that support the hardware lines, you need to have a proper driver that supports hardware handshake as well (The USB stick needs to convert the pin change to a USB handshake packet and send that to the host and vice versa)

So, the first questions is: Does the chipset on the dongle support hardware handshake? The most common chips known to do that are FTDI USB/Serial chips. In case your dongle has one (and not a cheap Chinese rip-off), chances are high it works.

Another common chip range is the Prolific 2303 - Of these, only the SA, HXD and RA variant seems to support hardware handshake. The others don't (Those are mostly intended for printer interfaces only).

That is the first step to success - The next one is if the Dongle maker managed to expose the hardware handshake lines from the chip - Some do, some don't.

And the next step is whether you got a proper USB driver on the host computer that supports Hardware Handshake. Again, some do, some don't.

Best check very carefully the above points in the product description before you buy such a dongle to get HWHS to work

Hardware / Re: SymbiFace3 is near your Enterprise...
« on: 2018.October.27. 14:21:39 »
"Do you think there is a demand for this card for the Enterprise?
will cost around € 89

Now, that's a bit of a silly question with an obvious answer: YES

Interface / Re: Tape emulator vs HxC vs SD Card interface ?
« on: 2018.September.01. 14:57:31 »
I was in your situation some months ago and my favourite storage would have been the SD card interface. I have repeatedly tried to contact SzörG who used to make them, but he doesn't seem to produce them any more.

My second best choice was a disk interface, I now have one of pear's EXOS cards (here) and am entirely happy with it (Maybe not as happy as with an SD card, but happy enough). I use the EXOS card with a dual "real" floppy drive, but a HxC wouldn't be much different.

It would be nice if someone could be persuaded to produce a number of new SD card cartridges.

Interface / Re: Creating EXDOS card clone
« on: 2018.July.31. 22:29:09 »
What I want to know: how change the mounted images from the host computer?

Here's the Manual:

https://hxc2001.com/download/floppy_drive_emulator/SDCard_HxC_Floppy_Emulator_Direct_Access_mode.pdf

You "move" the "head" to track 255, this switches the HxC to a special mode.
"Sector" 0 on "Track" 255 will then give you access to a status/control sector you can read and write to. Use the "struct direct_access_cmd_sector_" to write command 4 (SELECT_IMAGE_INDEX) with an appropriate image index.
Wait for one index pulse from the disk, then read sector 0 again to verify your command has been executed.

Once you "move" the "head" back to track 0, the image should be selected.

Using other commands, you can even achieve full LBA access to the complete SD card.

Programming / Re: SHA-1 / HTTPS on a Z80?
« on: 2018.July.21. 11:07:23 »
Brilliant!

Nice to see how an 80ies CPU would have struggled with tasks we consider "minor background processing" on modern computers.

Thanks!

You don't need to be an "average Hungarian EP owner" to know that - He cites German Wikipedia in his auction text.

I have sent you a PM some time ago - Interest in the SD interface is still there.

PRIVAT-85 and PRIVAT-86 german accounting software adverts:
Not quite. Actually a program to do your yearly income tax declaration.

The others are adverts for software to exercise foreign language vocabulary.
