Re: Cumulus with Wifi/SD Card?
This is very interesting device indeed! I bought a cheap one and after month will give feedback how it works with cumulus :). If it works this will be not only timesaver for developers (and for lazy users ;)) but also will preserve the SD card connector which in cumulus is very fragile part ! ezshar...

Re: Replace XT1 and XT2 crystals
Any 12 MHz will work. For repair I prefer to use crystals with small footprint:
BTW, many Oric's have a transistor soldered next to modulator (i.e. not only a capacitor) - this is not a repair but 'standard' feature .- Sat Mar 09, 2019 5:03 pm

Re: How to create random number with machine code?
Well spotted, goyo ! This algo actually generates chains with period of 256 and "will cycle through the values $00-$ff exactly once, in a scrambled order". I.e it's like doing "shuffle" but with 256 cards :). I recall that I've used this code because it was small and I needed onl...

Re: Oric Speech Synthesizer + Cumulus/Microdisk
It's "Molex MiniFitKK 4pin Header Male 2.54mm" or from China "a2542 connector". Assembled cable - HERE (link is just example). Unfortunately google image search returns only white or brown connectors. Keep in mind that female connectors are sold as housing and metal pins separate...

So, nothing means just black TV screen or there are bars or something? Can you try with SCART?Traindriver69 wrote: ↑Fri Mar 01, 2019 7:03 pm I have tried it through the rf cable to a tv and nothing and keyboard no sound.

Re: Dead oric 1
OK, you can try another measuring - it's not scientific, but in practice is used sometimes: Remove the power adapter, set the multi-meter to measure resistance (2k) and measure again at IC10 (or IC11) - i.e. black probe to black arrow and red probe to red arrow - warning again do this with UNPOWERED...

Re: Dead oric 1
Stop! 2m is too small and can damage the multi-meter!
You can use 20m/10A - but put the probe in the other hole as on picture (where is a label 10A).

Re: Dead oric 1
Cool! 7905 is working fine and the board is powered OK.
To measure the drawn current use: Be careful: set the multimeter to 2A (or 2000mA).

Re: Dead oric 1
Just checked the points on the board that iss said to check and IC10 the red arrow point is measuring 9.6v IC10 the black arrow point is measuring 4,4v IC11 point is showing 8.93v Sorry if I mislead you - to measure the voltage in above picture put the black test probe where the black arrow points ...
