Welcome!

Ahh the A3010 0.3% better than the A3000

Well, that is what the stack is for!

Remove stuff until you have a minimal example which crashes and post the code. It isn't clear to me what machine you are targetting either, is it the Elk then?

Running short on PCBs now, and not sure if I should order up a second batch.

I imagine the PCBs are not cheap so I'd take names and order more PCBs if interest got over a sensible threshold.

Welcome!

Did you update the OS copy of the ROM page register (&F4) before changing the register?

Daniel is correct. Loading HiBASIC from disc is a good idea. You can try with HiBASIC versions 2, 3 and 4. http://mdfs.net/Software/BBCBasic/BBC/

I should think so. All you need is an adapter.

Pins 1-40 are straight through. You'd need power & ground on the correct pins 41-44.

eBay is full of adapters you could hack.

I looked up the EtherLan 600 on Google. If no one knows how to reflash the chip in situ, then it wouldn't be hard to take the memory chip off & reprogram/replace it and solder it back.

Yes no problem.

It is altering the disk image then. I see your FF.CFG has extend-image=no I have all defaults except host=acorn & index-suppression = no You could try the last 0.x version of FF too.. I used 0.15 for ages and only recently tried something newer. Did you try an SSD image which is already the full size?

I specifically meant does the file written on the BBC read the same in an emulator? Is it even updating the catalogue of the disk?

If you transfer the image to an emulator do you get the same contents?

Try:
*DUMP on BBC
move stick to BeebEM (other emulators are available)
mount & *DUMP on PC

This might confirm if anything is actually being written to the stick...

While you are at it try another USB stick.

Try 1.2 first. That is the latest official release.

Try the alpha (not even beta) v2.6a if you want to be on the bleeding edge after you've got a known working setup, I'd say.

Which FlashFloppy firmware are you running now?

The 2.x branch is the development branch and has had some regressions (including SSD/DSD autoextend it seems from 2.6a release notes).

Sorry sold elsewhere. That was quick :S

I am having a clear out and selling my M512 copro. Board (no standoffs), manual, PC keys card and spare CPU. I do have the disks but they have signs of mould so I do not recommend you use them if you want them. IMG files are available on the internet (omniflop or Gotek). I upgraded the CPU to a 80C1...

also interested in one, how much is shipping to Greece?
thanks!

ps. I could even settle for an unsoldered one, I can solder it my self no issues

£4.15 for Europe.

No kits, sorry just assembled boards.

Space is HEX &20
Zero is HEX &30

One bit different.

Looks like you are getting some single bit errors in the RAM if the 0s are persistent. Possibly a dodgy RAM chip or maybe IC14 perhaps?

OK. I need to fit my new mud flaps to my 90. I bet the rusty chocolate bolts LR use will snap off.

Yes you are getting constant interrupts from something. You need to start removing things which connect to the IRQ line. I'd take out the user VIA first (IC59 I think). Then if it is still bad remove the system VIA IC3 and put the chip that was in IC59 into there (or the machine won't boot properly)...

Yes check the IRQ pin on the CPU (pin 4) & see if it is stuck low.

In my experience TSOP style packages are fine to hand solder if the footprint is ~1mm wider than the package. So 0.4mm each side will be fine.

What I fid annoying about FPGA is the number of documents you need to scour to find out the information you need. Like this gem which isn't in the datasheet but in the "Intel® MAX® 10 FPGA Configuration User Guide" m10flash.png Edit: I solved the problem by writing a read UFM->RAM verilog module whi...

It is the only other machine I have seriously considered writing for. Xevious is a great example , its hard to believe that it is essentially 40 fat pixels of background plus two bytes and one bit of gfx. Is that impressive or is it just poor that the latest Firefox is using 8 processes and 1GB of ...

I have some spare EPROMs I think... I ordered 10 from China and only used 4 in my A3000 so I am 99% sure I have 6 left.

I did a 4MB RAM upgrade for the A3000 still got boards left from batch 2.

Good work

Another machine back from the brink. They are quite usable with 4MB RAM and an IDE interface.

I blew some EPROMs to upgrade mine to Risc OS 3.11 too.

RPCemu is probably worth a shot. https://www.4corn.co.uk/articles/rpcemu371win/

One of the current maintainers is member flibble on this forum.

The ROM has 0.A3 on which is what I got with the issue 4 Turbo MMC. So I imagine it is compatible with SmartSPI and MMFS.

J-leads are a pain to solder on any package.

That's why I stopped using the PLCC EEPROMs on my boards & changed to a TSOP package instead. Even using a stencil, paste and hot air I had to manually fix 2-3 of the connections per package.
