Re: Clock Signal — an Oric emulator for macOS and Linux

@ThomH : Amazing work :!: Here some thoughts: - BD500 - it works, but if you type just after boot screen command "DIR" then it lists first part of filenames and waits for key, if you wait more (i.e. 10 sec) and press key then an error is issued : ?Drive Error . It looks like there is kind of timeou...

Regarding the differences, I was only expecting changes making the machine either easier or cheaper to produce: It's supposed to be 100% compatible with the Oric Atmos at the software level.
Will see... I've just got one (from the same source)! 8)

Re: ULA versions

From an old post: 7x or 8x after CDI is probably the chip revision, (or batch), the last 4 numbers are YYWW with YY the two last digit of the year and the next two the week of manufacturing: 8422 will be 1984, Week 22. The first in your list is probably a typo? Here is " The big Oric ULA Database " ...

Re: Sedoric's TAKE command, help required...

About the buffers you can protect them from BASIC with HIMEM#ADDRESS where ADDRESS is set just bellow the buffers. But this is bit ugly and it's possible that your program goes 'OUT OF MEMORY'. Well, it would be very helpful if someone with more knowledge in Sedoric internals shares how to set the b...

Re: Gotek USB floppy emulator

I have an idea for more universal "floppy switcher" but so far I didn't found a good looking solution (not electrically but the out-look only). Else using toggle switches is nice and very effective. For instance like this one - the link is just an example. I think the name is something like ON-OFF-O...

Re: Gotek USB floppy emulator

Great! I totally share your opinions about LCD/OLED, buttons, etc.
Additionally I drill a hole for the red LED and bend it like the green one - it blinks nicely by write operations and I don't see reason to leave it hidden inside the box.

Re: I2C for the Oric

This is crazy cool ... and working! Nice!
On your question: IMO, there should be no problem to use the Parallel port as I2C, but it depends how "Oric compatible" the whole thing should to be.

Re: Oriclopedia: A series of videos on all things Oric

Regarding the machines, I will have to wait for the diagnostic cartridge from Vyper, but what I can tell you is that the motherboard uses 2 memory chips (tms4464-15nl) instead of the usual 8, and nowhere is written "Designed by Tangerine Computer Systems Ltd" (but there is a "ORIC 1". One of the ma...

Re: Oriclopedia: A series of videos on all things Oric

Wow, I'm totally speechless! :shock: Congrats for Oric Nova64's - they look in very good shape and making them work should be easy. IMO, you may definitely do something with the power boxes - it's pity to have such big case only for power supply. If you already have a Gotek can you check how it fits...

Re: ROM 1.22?

I am curious, however, about why you want to put a new ROM in an Oric. For those particular ROMs 1.2x I'm really nice surprised by the way they are made - all changes are on carefully selected places, without affecting the well known and commonly used BASIC entry points, so no big concerns about th...

I do not remember ever having encountered this problem with my Jasmin.
Do you have the same problem within other address ranges?
No, I've tested every page as read buffer and it works i.e. no problems at 0x0200-0x02FF, 0x0400...0x8FFF and even 0xC000...0xFFFF with RAM overlay enabled.

Re: ROM 1.22?

Just remember that the Oric with the EPROM won't work with a disk interface (I think also won't with Erebus) out of the box. It needs some hardware patching. +1 Good advice! And the common sense is to follow it ... but don't forget this is Oric ! Here is at-least one proof that there are exceptions...
