Re: Cumana disk interface problem

Still had no joy with the Gotek so I am not sure if the board is 100% I think I will try a HxC SD Card Interface from lotharek in the new year. So we will see after Christmas.

Re: New Member and New Oric Atmos Owner

Great result!

I bought my DRAM and spare ULA as well as a 8912 from Bulgaria. Does this mean someone has a load of Pravetz spares?

Re: Cumana disk interface problem

I can't speak for the Gotek, but HxC manual has detailed information on the jumper setting according to which type of computer you intend tu plug it (basically ST/Amiga or PC or Amstrad), and of course flat or twisted cable. Using a twisted cable for Oric apparently results in inverted logic, so in...

Re: Cumana disk interface problem

I have tried it with Flash Floppy and when that did not work I bought a HxC license and tried that as well. Both produced the same response as I described earlier. I converted the Oric .dsk files to .hfe files on Windows using the Floppy Manager software that comes with HxC and when I look at the .h...

Re: Cumana disk interface problem

I have been plugging away at getting this working ( massive thanks to MikeB ) and now I can get it to the “insert system disk” prompt and my GOTEK is lit. Then I get the error “no operating system on disk” so I don’t know if the Cumana is the problem or is it the GOTEK not playing with the Cumana PC...

Re: Sedoric 4.0

First, a quick question about Goteks. There are many different Sellers on Amazon & Ebay, selling them for wildly varying prices - in your experience, are ALL of these drives 'flashable'? In other words, does Gotek, or whoever makes these, manufacture different versions, cheap ones that are non-flas...

Re: New Member and New Oric Atmos Owner

I have a 16KB EPROM burned with the test ROM if you want to borrow it. Haven’t read all of the thread so just to say have you changed the 12Mhz Crystal?

Hi Silicebit,

Do you have any more of these interfaces left or are they all spoken for?

Re: Connecting to a tape recorder in 2019

I mainly use my laptop and Audacity with Novalight these days but I do use real cassette sometimes so this is very interesting to me. I may replace R8 in one of my Oric’s and do some testing :D

Re: Connecting to a tape recorder in 2019

Re: Sedoric 4.0

I had a few headaches with Goteks when I first started out but I have had more success lately. Now I have the correct USB programmer I have managed to program HxC Firmware and FlashFloppy firmware. I did the OLED screen and sound mods too. If anyone wants one programmed then PM me - free - no charge...

Re: Cumana disk interface problem

Yes Slicebit I was taking the readings from the wrong pins they all read 4.9v :shock: :oops:

Will look at RV1 and see what I get some time. So it looks like it’s probably the power or the ROM or something else
