Re: Compatible transister ?

Three transistors, TR1 in tape input circuitry (collector connected to pin 18 of VIA 6522), TR2 in keyboard interface (collector connected to pin 13 of VIA 6522) and TR3 to activate tape relay. All them working in commutation mode.

Re: Transformer/ power supply

Here's a picture Two voltage regulators 7805 and 7812. I'm guessing 5V and 12 V Yes. :-) There's a bridge rectifier RS402L Can't get one of these very easily. Could I substitute a similar one ? Search for GBL01. Havent' poked my probes at it. I'm a bit scared of 240V. But the interface powers up bu...

Re: Oric Atmos resets after a few seconds ... when not grounded

In this thread you can see an Oric with ROM: http://forum.defence-force.org/viewtopi ... 733#p15730

To use Microdisc controller with EPROM or EEPROM you can use this invention.http://retrowiki.es/viewtopic.php?f=7&t=200031702

AH, i see that my items are ready. Great :D
I sent you a PM :-)
Please check your inbox, you have a PM.

The controller can be used with Oric Atmos and Oric-1, but the Oric-1 must have ROM, not EPROMs. You can use 5.25", 3.5" and 3" disk drives, HxC, HxC slim and Gotek with HxC firmware.

List updated in first post.
It is not about the last batch yet, right?
You are right, it's not the last batch. As very well Chema said, I don't start a new batch until the last one is finished.
