Én is, nagyon jó!

A USING formázza a változó számot vagy karakterláncot a képernyő vagy a nyomtató helyén. Jó irodai munkákhoz.

No problem, my enthusiasm for the SymbiFace3 and the Enterprise has grown even more, now that Zozo has got interested on it....

Eventually, every little success  will be extensively described here to all.

The Symbiface3 expansion card, as you already know, is a CPC card created by Hans, TMTLogic group, commissioned by Prodatron, creator of the famed SymbOS multi micro-computer operative system.

This means that the SF3 card has been created with a variety of Z80 computers in mind, including our Enterprise.

Actually, being a CPC card, it needs a re-programation of the CPLD that controls its input and output signals, no more being a CPC card except by its connector, that needs to be converted to an Enterprise slot connector by means of a dummy bridge board.

As you can see, it works flawlessly on I/O mode, even on 10Mhz frequency, but it needs some minor fixings on the memory management side to be perfect.

Also, it needs to be integrated on EXOS to be considered "real Enterprise hardware".  For example, the included Real Time Clock, mouse port, USB port, SD port, Wifi module, etc, will be integrated with drivers on the system, allowing natural EXOS access to them. It will be a huge task, that surely will also need rewriting of the SF3 core.

Is by those reasons that the release of the SF3 as an Enterprise product still will take months, sorry.

New SF3 update. I have re-written the Basic program. Also the manual has been updated.

Wifi engine cleaned and enhanced. Now, the Basic listing doesn't need machine code to listen the web stations.

I have made minor changes on the "webradio.bas" program.

Hans is re-writing the Wifi Engine.

By now, to maintain the Radio reception, the EP has to continually execute 2 SF3 commands in machine code. Also, for example, some radio IPs work at my office but not at home.

Probably this task will be done by the Arm processor on the next SF3 upgrade. Then, this program will be obsolete and re-written.

I got delivery for 25UK Pounds - which I was happy with at the end of the day.

Congratulations! you have found a seller with integrity...

Azt hiszem, jobbak vagyunk, mint más számítógép-felhasználók. Gondolj például az Amigákra, miután a Commodore 1994-es bukása után még mindig azon ítéletekben vannak, hogy tudják, ki az igazi tulajdonos.


I think we are better than other  computer users. Think for example on Amigas, after the fall of Commodore on 1994 they still are on judgements to know who is the real owner.

Ask how much the delivery from Hungary, sometimes the total expenses are not worth it.

Hans(from TMTLogic) has just added a new function to the superb SymbiFace3 card: webradio.

The procedure is to open a socket on the wifi module to the stream IP and then feed the data received to the music player chip. Surely not a great explanation, but is all what I can say about how it is done. The result is impressive, as you can see on this video:


The two radio stream IPs have been took from https://www.internet-radio.com

The Basic program is very simple(and probably not very neat inside), although a little machine code subroutine has been added to make things faster.

It seems an Issue 6. Probably with an updated Nick. They have put a heat-sink over it. A lot of humidity and a date of reparation on the sticker. It will need an internal memory expansion.

You have a socket for the Z80... ready for a turbo hack...

But.... It seems that has been used for parts, probably due to some irreparable failure.

The problem with GET is that it is trapped by the PC RTS/CTS protocol, STATUS_IN is set(negative on the signal) even if there is nothing to receive from the PC, so the Enterprise waits forever. Is for that I have used a "conversation" scheme instead of the Half duplex one. The control is alternated between the PC and the Enterprise when an Enter is received(13, Ctrl+M).

It uses the default... 9600 8, 2, 0, Handsake. The chip CH340G adapts itself and converts to a virtual serial port on the USB at the PC.

The program has been written by me, but it has some faults.

Zozo, you described a way to use READ instead of GET, but I have not been able to find the way. Can you explain it?

« on: 2019.July.02. 22:09:06 »
There is a serial card, the schematics is here. It was a Hungarian "classic-time" project intended for use with serial mice(or serial external keyboard), but has been superseded by the EnterMice.

The Mouse driver deals(more or less) with that card. You can peek on the code if you want to know how it can be accessed. It is based on a PC UART, so it can be used for other tasks.

Also on classic times, a Danish firm developed an external serial card, even they run for a time an Enterprise oriented BBS. The software has been preserved, but not the hardware.
