WxAxNxDxExRxExR Posted February 2 Share Posted February 2 Hello, I am planning on making a cable as per above. However, being new to Atari8, I have no idea about all the pins that need connecting for such an application! Anyone tried this already? If you have on of these already, would you mind checking the pins? On the minimum I guess I need to connect power (+5V or 12V?), GND (apparently only one of the two is normally used), motor control, some means of data in and out...

sup8pdct Posted February 2 Share Posted February 2 Sio in, Gnd, Sio out, Gnd, Motor control, +5v, and Audio in. They are pins 3,4,5,6,8,10,11. Yes, there are 2 Grounds. Quote Link to comment Share on other sites More sharing options...

Yes, there are 2 Grounds. Thanks, that's what I thought, though I guess for a 1010-specific cable one can ignore +5V and GND... I noticed that one of the GNDs doesn't appear connected at all in the (nearly) complete, remade cables on eBay, they also use 12 core cables... I guess I will just interconnect both GNDs with a single core, don't see why not. Quote Link to comment Share on other sites More sharing options...
sup8pdct Posted February 2 Share Posted February 2 Both Gnds connected at either end anyway. 12 core cable is fine, tho it should drop the +12v. As far as i know, nothing uses that and it isn't on XL/XE anyway. Only 400/800. Quote Link to comment Share on other sites More sharing options...
Rybags Posted February 2 Share Posted February 2 For just cassette loading alone you could get away with just GND and Serial Data In. Add Serial Data Out if wanting write operations. Motor control only needed if your device has that functionality. In theory you could use it on an emulated device as a prompt to commence operating. When doing tape read (OPEN) by CIO there's a set delay where input is ignored to cater for leader and unwanted noise (10 seconds?) Audio In only needed if your external device is to supply audio. It gets mixed with Pokey and keyboard click sound but isn't detectable or able to be processed by the host computer (sadly) Quote Link to comment Share on other sites More sharing options...
baktra Posted February 2 Share Posted February 2 If you want some support for emulating a data recorder with one of the turbo upgrades, consider also connecting the COMMAND wire. 3 Quote Link to comment Share on other sites More sharing options...

WxAxNxDxExRxExR Posted February 2 Author Share Posted February 2 8 minutes ago, _The Doctor__ said: ground, rd, sd, mtr, cmd For future reference and if someone else reads it with the sam aim as me, I read in the documentation that the cassette player is a 'dummy' device, i.e. it ignores Command altogether. Hence, the full, correct answer is per below. GND pins can/should be interconnected with one core, hence a six core cable is required. The 1010 users can skip at least +5V (possibly even GND) as it has its own power supply, but that would be a bit of an exaggeration, in my view. 12 hours ago, sup8pdct said: Sio in, Gnd, Sio out, Gnd, Motor control, +5v, and Audio in.

Thanks, but i don't have any of those, and don't intent to use them. Given all the gadgets out there all of which are muchf aster and more convenient than cassette, I am simply doing this for completeness sake.

_The Doctor__ Posted February 2 Share Posted February 2 (edited) Wait a second? Making a dedicated tape player? So you just want to play an Audio tape? No reading or sending of Data? Does the tape player have it's own speaker? If that's the case, just motor and ground to turn it off and on. Audio if it has not speaker... otherwise my post above is for everything as a full data cassette tape player/recorder with or without mods should need Edited February 2 by _The Doctor__ Quote Link to comment Share on other sites More sharing options...
WxAxNxDxExRxExR Posted February 2 Author Share Posted February 2 The complete list above includes DATA in and out (designated SIO in and out). Audio in is a left channel signal used for some training software, i.e. it played real human voice or music while loading the software, and such. Not a definite "must", but I am connecting it for completeness sake. Quote Link to comment Share on other sites More sharing options...

+kheller2 Posted February 2 Share Posted February 2 You need 5 lines as shown in the 1010 schematics. Data IN, OUT, GND (pin 4), Motor Control, Audio Out. Quote Link to comment Share on other sites More sharing options...
WxAxNxDxExRxExR Posted February 2 Author Share Posted February 2 (edited) There you go, that's what we basically concluded above... XC12 requires +5V as well, though. Edited February 2 by WxAxNxDxExRxExR XC12 Quote Link to comment Share on other sites More sharing options...

But not the 410. Where are we going with this? 😁 Quote Link to comment Share on other sites More sharing options...
WxAxNxDxExRxExR Posted February 2 Author Share Posted February 2 That if you want a cable which works with all cassette players, you need 6 cores, as we concluded above. Quote Link to comment Share on other sites More sharing options...
+kheller2 Posted February 2 Share Posted February 2 And one more wire for CMD and you basically have everything needed for almost everything. Quote Link to comment Share on other sites More sharing options...
WxAxNxDxExRxExR Posted February 2 Author Share Posted February 2 There a five(5) or six (6) more wires which are needed for a complete SIO cable... Five for XE/XL, six for 400/800 (possibly even 1200XL?) compatibility. Quote Link to comment Share on other sites More sharing options...
+kheller2 Posted February 2 Share Posted February 2 I would like to know what devices required 12V, Clock In/Out, Interrupt, and Proceed (850 ). Quote Link to comment Share on other sites More sharing options...
sup8pdct Posted February 4 Share Posted February 4 12V, nothing as far as i know. Clock in and clock out, actually one is a bidirectional clock. I think the midimate interface uses clock in so pokey sends/receives data at the correct rate. Other midi interfaces dont as the selected pokey divisor is close enough, but there may be devices that are picky about data rate. Proceed and interrupt i believe are used by Rverter interface. Some clones don't. Quote Link to comment Share on other sites More sharing options...
