Although, having trouble getting it to export a gerber, how many layers are these builds meant to have... only two... or more?
It's possible he has and I missed it, I don't know.Speccy_Pete wrote: ↑Mon Aug 09, 2021 1:32 pm I thought Dylan had tested the newer boards and had them working, if not... How's Ben going to build a new batch?
Appreciate the confirmation, the other program I had loaded was messing up... for some reason it thought it was 7 layers?
Yep, I know Ben has other commitments now so his time doing this stuff is more limited.It's possible he has and I missed it, I don't know.
Equally Ben might well be building a batch on the old PCBs, with stock of AMD flash chips he's scrounged together.
I think the reason they've been out of stock is just Ben not having time to do everything, not a hold up on boards or parts.
The issue is the 1 megabit flash ROM. When the Spectranet was designed it was already an old part, but they were still available. In the years since they've been discontinued as the fab plants with the capability to make them shut down as far as I understand.Speccy_Pete wrote: ↑Mon Aug 09, 2021 9:52 pm So the board update is due to part availability... no new features as such then?
Ah right, appreciate the detailed reply...Guesser wrote: ↑Mon Aug 09, 2021 11:56 pm The issue is the 1 megabit flash ROM.

There are still a few NOR flash parts in production, made by microchip, but the particular AMD chips Dylan used were in a looooooong package and the microchip ones are in a shorter variant. It's a shame that he didn't design it around the PLCC package version as then the new ones would be interchangeable, and it would also have made them much easier to solder too, but he didn't and redesigning the board for that would take major layout/routing changes so it's just adapted to take the shorter TSOP variant instead.
Dylan confirmed the correct one to use.
No point reinventing the wheel as it were... The board works.Guesser wrote: ↑Fri Aug 13, 2021 9:56 pm At that point you're changing so much though, you might as well just design from scratch.
Making it vertical would be possible, but it's not as simple as just soldering a bit of PCB onto the back of every pin of the edge connector like usual as the through port doesn't put every pin straight through. The A15 and ROMCS signals go via the CPLD for the downstream paging inhibit feature.
There's no kicad anything... Just a schematic, netlist, and pcb layout for gschem and pcb along with symbols and footprints for the unusual parts.Speccy_Pete wrote: ↑Fri Aug 13, 2021 11:09 pm But it's mute anyway, even though theres a kicad schematic included on the github it isn't compatible, from what I understand because of gschem... so yes... only way to do it with easyeda is redoing the complete board unfortunately.
Yep, your right... No idea why or where I got that stuck in my head.
(Really need a smilies head banging a wall right here)
Many thanks for your response.MonkZy wrote: ↑Thu Aug 19, 2021 7:10 am If you use the command %fsconfig you can set the filesystem permanently and also toggle the autoboot setting, all via a menu. After you exit the menu, reset the spectrum to apply the new settings.

I can only think you are typing in "LINE" manually as a keyword.SpaceCadetFarley wrote: ↑Sun Aug 29, 2021 11:43 pm %save "program" LINE 10
If I type the above, I get a ? before the LINE keyword. If I don't use quotation marks around the filename I then get a question mark after the LINE 10.
Blimey! That has worked. Thank you. What a pain that was. I wrongly assumed that as the load command was manually typed LINE would be as well.p13z wrote: ↑Mon Aug 30, 2021 4:21 amI can only think you are typing in "LINE" manually as a keyword.SpaceCadetFarley wrote: ↑Sun Aug 29, 2021 11:43 pm %save "program" LINE 10

The "LINE" must be the token as used in normal BASIC, not typed in like the "load" command for the Spectranet parser.
( press shift+symbol shift together to get the E cursor, then hold symbol shift and number 3 to get the LINE command / token ).
Hope that helps.
