From jdigreze To All 3 November 2005

Hello caro There is one more purely technological question... Kamil, which editor do you use schematic diagrams?

From Kamil Karimov To All 3 November 2005

Hello jdigreze jdi> ... what circuit diagram editor do you use? Now P-CAD.

From jdigreze To All 4 November 2005

Hello caro Maybe... Then the question arises about making an adapter from Kay's slot, let's say for a 40-pin "comb".

From jdigreze To All 4 November 2005

Hello caro It’s bad... I’ll have to manually redraw the diagram in Eagle. But thanks anyway! I want to light the stove. fee. Try this device in action.

From Kamil Karimov To All 4 November 2005

Hello jdigreze jdi> ... I want to light the stove. fee. Try this device in action. For the sake of one thing, does it make sense to make a printed circuit board? I assembled it on a breadboard for debugging - it works great.

From Yaroslavtsev Yaroslav Andreevich To All 4 November 2005

Hello jdigreze jdi> Maybe... Then the question arises about making an adapter with jdi> kay's slot, for example on a 40-pin "comb". I made a board into a slot, I didn’t like it. There were too many jumpers. It should work better with an adapter. File: mcard.jpg http://zx.pk.ru/attachment.php?attachmentid=1894

From Chunin Roman To All 4 November 2005

Hello Yaroslav Yar> I made a board for the slot, I didn’t like it. Too many jumpers. Yar> It should work better with an adapter. The adapter reduces reliability! And what didn’t you manage to resolve as normal?

From Yaroslavtsev Yaroslav Andreevich To All 4 November 2005

Hello, CHRV CHR> The adapter reduces reliability! CHR> What didn’t you manage to resolve as normal? Yes, I did it hastily; I didn’t have time to properly suck the wiring.

From Igor Afonkin To All 17 February 2006

Hello caro Cool! I'm looking forward to the results ;)

From Kamil Karimov To All 17 February 2006

Hello, CHRV Received 20 boards. I collected one. I'll turn it on tomorrow. File: ZXMCARD.JPG http://zx.pk.ru/attachment.php?attachmentid=2614

From Alexander Shushkov To All 17 February 2006

Hello jdigreze jdi> Cool! jdi> I'm looking forward to the results And I'm waiting for 5 ordered copies :)

From Oleg Golenkoff To All 18 February 2006

Hello caro car> Received 20 payments. car> I collected one. car> Tomorrow I will turn it on. How much will it cost? and how can I order? :rolleyes:

From Alexander Zan To All 18 February 2006

Hello, breeze car> Received 20 payments. car> I collected one. car> Tomorrow I will turn it on. Is this option already with a virtual VGshka? Or am I racing?) If not, then in the future it will be possible to connect cards to this scarf memory? Those. Are the necessary pins provided?

And for the price, the device is generally unrivaled. but IMHO it’s better still Segov’s its connector is the no less common DBF-9 (the plug breaks off with motherboard (com port) or purchased from any radio parts), more buttons (8, instead of 4 dandy ones (regular and turbo I count as one, EU)) and it’s more convenient, all curved like that :cool: The dandy “parallelepiped” has no ergonomics at all :rolleyes: the downside, however, is that it will require more contacts, parallel after all..

From Alexandr Tsidaev To All 18 February 2006

Hello, Witch Doctor > Yes, there is power in the SEG joystick... :) only a controller seems to be needed... > or not ? current if suddenly the mega doesn’t have enough legs and you have to remake the parallel code into sequential By the way, this diagram didn’t work for me, I connected it according to the diagram where all the data transmitted via the main port (2-9 pins of the LPT connector), it works with a bang. Moreover +5v I haven’t connected it anywhere, I still don’t understand how it’s done :)

From Witch Doctor To All 18 February 2006

Hello Eltaron Yes, there is power in the Sega joystick... :) but it seems like you need a controller... or not? File: SegaDirectPadPro.gif http://zx.pk.ru/attachment.php?attachmentid=2623

From Konstantin Zhukov To All 18 February 2006

Hello fan Kamil, how about adding a quorum keyboard to the controller. IMHO it is better to connect a dandy joystick, because... this creates an opportunity it’s easy to convert a one-button Spekov joystick into a 4-button Dandy joystick (at Spekovsky has 6 wires, and Dendivsky has 5. Other joysticks have the same number there are many more wires, which does not allow it to be used for connection plug SSH-5, common on specs). Secondly, the dandy joystick has hardware TURBO buttons have been implemented. And for the price, the device is generally unrivaled.

From Kamil Karimov To All 19 February 2006

Hello jdigreze jdi> I'm looking forward to the results ;) The new board with the firmware posted in the first post of this topic works without problems. So far I have not found a single error in the tracing. Now I’ll add RS232 support to the firmware and try to connect the modem.

From Andreas Kaiser To All 20 February 2006

Hello caro car> The new board with the firmware posted in the first post of this topic works car> no problem. car> I haven't found a single error in the tracing yet. car> Now I'll add RS232 support to the firmware and try to connect car> modem. Kamil, what pinout is the board for? Judging by the photograph she is simply you insert everything and I suspect that you insert it into Quorum, right?

From Kamil Karimov To All 20 February 2006

Hello icebear ice> Kamil, what pinout is the board for? ZX-bus, in the form used in the main Spectrum models. Contact pitch 2.54 mm ice> Judging by the photo, you just insert it and that’s it, and I suspect that ice> you insert it into Quorum, right? The system connector in Quorums is made in the form of a ZX-bus edge connector, since this is done in branded Spectrums. That is, there are no slots for connection. But I just connected two slot connectors to each other. As a result, through this adapter I connected the board to both Quorum and to the branded ZX-Spectrum 2+.

From Kamil Karimov To All 1 March 2006

Hello Yaroslav Yar> Are there any available for sale? If so, how much does it cost? For now. The cost of the board itself was about 130 rubles. (I paid a little more than 2600 rubles for the production of 20 boards). Shipping within Russia now costs from 80 to 100 rubles.

From Yaroslavtsev Yaroslav Andreevich To All 1 March 2006

Hello caro car> Received 20 payments. Are there any available for sale? If so, how much does it cost?

From Kamil Karimov To All 1 March 2006

Hello Yaroslav Yar> I'll take one too. Write in PM.

From Konstantin Zhukov To All 1 March 2006

Hello caro I'll take it. Please provide details of where to pay.

From Yaroslavtsev Yaroslav Andreevich To All 1 March 2006

Hello, Jukov Juk> I'll take it. Provide details of where to pay. I'll take one too.

From Alexandr Tsidaev To All 3 March 2006

Hello caro a little offtopic: what and how to solder all these surface components? I would take handkerchief, but I don’t know if it’s really possible to solder all this horror ;) with an ordinary shovel soldering iron :)

From Dobrynin Sergey To All 3 March 2006

Hello Eltaron Elt> a little offtopic: what and how to solder all these surface components? I Elt> I would take a handkerchief, but I don’t know if it’s realistic to solder all this horror Elt> with a regular soldering iron There is nothing terrible there. Leg pitch 1.25 (1.27) mm solders perfectly, even easier than DIP with a pitch of 2.5 (2.54) mm...

From Kamil Karimov To All 3 March 2006

Hello Eltaron Elt> ... is it really possible to solder all this horror ;) with an ordinary soldering iron Elt> :) Soldering iron with a thin tip, no more than 25 watts (preferably with a temperature controller, but not necessary), and everything works out with a bang.

From Alexey Korotkov To All 13 March 2006

Hello caro Are orders still being accepted? I wouldn't mind either... Is it possible to arrange this? and how? I would like the collected fee.

From Kamil Karimov To All 18 March 2006

Hello caro Updated the version of the ZX_MCard bootloader (see post 1.) Now it can be called by pressing ALT+Pause without turning off computer. Naturally, this works if the current firmware supports the operation normally keyboards. To force the bootloader to start as in the old version, necessary install a jumper between pins 1 and 2 of X5 (supply ground to pin 29 ATMega8515).

From Kirill Frolov To All 24 March 2006

Hello caro car> AVR free ASTUDIO. AVRA for everything small and GCC for everything big.

From Kirill Frolov To All 24 March 2006

Hello caro car> For this, there are commands for setting the RS232 speed. car> And to synchronize the work, the XON/XOFF protocol. Speed setting commands assume setting exclusively MAXIMUM speed... XON/XOFF only works in the Spectrum->PC data flow direction. in reverse PC may not have time to react. XON/XOFF introduces more delays into the process data transfer. XON/XOFF cannot be used in only one direction (while in another, for example, RTS/CTS) (ie, maybe, but it's hacking). XON/XOFF is NOT a FULLY 8-bit TRANSPARENT protocol. He doesn't allow for example, use X-modem (and this could be, or Y-modem, work quickly Z-modem due to its extreme simplicity).

From Kirill Frolov To All 24 March 2006

Hello, random ran> Judging by the diagram, RS232 is not complete, important signals are missing ran> reliable data reception/transmission on slow hardware like Spectrum ran> is practically impossible. I'm talking about DCD, DSR, CTS signals. ran> DCD --carrier detect DSR -- modem ready not really needed. but when working /specifically with a modem/ they are needed. because the modem may really not be ready, and it is not clear how (except according to the line CONNECT) determine the presence, and most importantly the loss, of the carrier. CTS is the problem.

From Kamil Karimov To All 27 March 2006

Hello fk0 fk0> ... CTS - that's the problem. I agree, for synchronous operation at high speeds it is necessary to have a mode CTS/RTS. This mode is provided in the card. Yesterday I tried to transfer files from IBM to Spectrum and vice versa via null modem cable. On Spectrum I worked in Melon v1.90i, on IBM - TeraTerm. Unfortunately, Melone has a maximum speed of 57600 baud. Therefore, it was not possible to try the maximum speed of 115200. At speed 57600 everything works without problems.

From SMT To All 3 April 2006

Hello caro I actually wanted to ask this in the topic about the video processor...

From Victor Ronin To All 3 April 2006

Hello caro car> This was the case with TurboSoundFM what does TSFM have to do with it? There are no new ports, everything is standard AY. Well unless it's some kind of nonsense with a shadow guy...

From Chunin Roman To All 3 April 2006

Hello Ronin Ron> and what does TSFM have to do with it? there are no new ports, everything is standard Ron> AY-shnoe. Well, maybe some nonsense with a shadow guy... Vit, I wrote about this in the topic on FMT. Look.

From Kamil Karimov To All 4 April 2006

Hello caro Posted a new firmware version for ZXMC - version 1.2 (see post 1) Keyboard, mouse, RS232, clock. PS. For those who assembled it themselves, I warn you about the need pull-up resistors on the i2c bus even in the absence of a clock.

From Orionsoft To All 8 April 2006

Hello caro What needs to be done to be compatible with [Scorpio&smuc&GS]?

From Orionsoft To All 8 April 2006

Hello caro It’s clear, there’s a conflict with the smuc ports, let’s attach a small circuit on the second floor, that’s for us not the first time... Thanks for the info! :v2_cheer:

From Kamil Karimov To All 8 April 2006

Hello Orionsoft Ori> What needs to be done to be compatible with [Scorpio&smuc&GS]? Unfortunately, there really was a problem with ZXMC compatibility with Scorpio + SMUC. -- cut --- >> HA> 2.

Is this not solved programmatically? I looked at the diagrams and descriptions of the SMUC ports. For normal functioning of SMUC with ZXMC you will have to do the latter complete decryption of ports. To do this you need to add one body LA1 or LI1. I could easily do this myself by gluing it to the board a small piece of a printed template with a soldered LA1 or LI1 body Can you do it yourself? It is necessary to cut the conductor on the board that comes from the busZX_BUS pin B10 (this is address A1) to pin 5 of the element DD2:2 (LI1). In this gap you need to insert the following diagram: ┌─- CODE ─── on LA1 ------ ___ ___ B10(A1) ___9_| | _1_| | B11(A2)__10_| | |_2_| | B12(A3)__12_| | |_4_| | B22(A6)__13_| | 8 | 5 | | 6 | o-----+---| o------ to pin 5 DD2:2 |___| |___| LA1 LA1 on LI1 ------ ___ B10(A1) ___1_|& |3 B11(A2) ___2_| |---+ |___| | ___ | ___ B12(A3) __12_|& |11 |_4_|& |6 B22(A6)__13_| |_____5_| |------ to pin 5 DD2:2 |___| |___| LI1 LI1 └── CODE ─── Thus, ZXMC will only work at single levels at A1,A2,A3,A6,A7, which should eliminate conflict with SMUC ports.

From Evgeny Muchkin To All 12 October 2006

Hello, ewgeny7 caro, how is it going with the implementation of speed control? mice?

From Grigory Kolbazanov To All 12 October 2006

Hello, Evgeny Muchkin I don’t understand, where is the diagram of this multimap or where can I look? or just to order?

From Kamil Karimov To All 12 October 2006

Hello, AHAHACbI AHA> I don’t understand, where is the diagram of this multimap or where can I look? AHA> or only to order? See http://zx.pk.ru/showpost.php?p=9958&postcount=1

From Evgeny Muchkin To All 13 October 2006

Hello axor axo> That's right. After all, in any case, to control the cursor from the mouse axo> some kind of driver is being written. So why doesn't he take up management axo> speed and other things... Yes, because a hundred thousand programs have already been written in which the driver is unregulated mice. I have never seen a single program like this before. Well, everything will have to be broken and a new driver shoved into each software old???! It will turn out to be some kind of bullshit. This is not correct.

From Evgeny Muchkin To All 13 October 2006

Hello caro It seems to me that this set of variable parameters will be more than plenty. What else is there to process programmatically? Overclock the mouse or something to do, by analogy as controlling the cursor arrow from the keyboard in most programs? :) And, to be honest, I would like a more convenient way to edit firmware. In general, the device turned out just great! Thank you, Camille!

From Alexander Shushkov To All 13 October 2006

Hello caro Evg> caro, how is it going with the implementation of adjustment capabilities Evg> mouse speed? car> There are, in principle, options, for example, filtering fast movements. There is no need to filter anything. So okay! The fact that the mouse runs faster than in other controllers (for example, in Scorpionovsky the mouse “ran” much more slower), so this is not such a big minus. You just need to get used to it. In general, I wrote a driver for the mouse (used in the game Vera and the Wheel polled), from which you can adjust the speed of cursor movement - like underestimate the speed and overestimate it. P.S. On my Kai, a Logitech sbd69 optical mouse is connected to the multicard.

From Alexander Shushkov To All 13 October 2006

Hello caro car> Maybe you're right, since ZXMC in this case simply transmits car> information from the mouse in the Spectrum. car> All final processing can be done in Spectrum. car> But of course you will have to configure the mouse from the Spectrum side. That's right. After all, in any case, to control the cursor from the mouse it is written some kind of driver. So why doesn't he start controlling the speed and other things...

From Elena Tarasova To All 13 October 2006

Hello caro car> Maybe some additional software processing is needed? By the way, I remembered one feature that RDC made on the ps/2 controller mice for Amiga, namely, limiting the change of counters per 1 frame, no more +-127. Or is it already there?

From Elena Tarasova To All 13 October 2006

Hello caro car> While there is no software control, what comes from the mouse is what car> is issued to ports. car> Per frame, if I understand correctly, this is between two interrupts (if car> talk about Spectrum)? car> Is there a need for such control? car> With a maximum resolution of 8 units/mm, we get a limit of 128/8 = car> 16mm in 20 ms. car> That is, the limit will be 16*50 = 8 m/sec. car> Is this necessary? It seems that this is easy to check - push the arrow into the corner of the screen and sharply Move the mouse in one direction so that the arrow rests on the curb. If she will suddenly take off, that is, there is a need. Of course, you can leave it like that, but shouldn’t you strive for perfection? Everything no pss...
