Re: Hello from UK!

Welcome to the group.
We need more programmers ;o)

There's lots of things for the Oric in the last few years. Various new bits of hardware and software. Have a read around the forum and you'll find mention of them.

There's lots of life left in the Oric yet!

Re: Printer?

I'll have to look into this. I haven't played with any Arduinos yet. There seem to be a lot of different types now and I don't know which would be good to go for. Did you get the other BD pages? There's some DOS6 pages in the Dropbox. I need to check the cables from the BD500 unit to the drive. Ther...

For me, quick solutions can be made relatively easy with Arduino+PC+printer or RPi+printer.
How does that work for Orics?

Re: Printer?

IIRC the problem with modern printer with the true type fonts was that they didn't necessarily recognise ASCII codes. My HP printer was supposed to have the ASCII character set, but nothing happened when I tried to print I'm not aware if any inkjet printers have Centronics ports. Most seem to be wif...

Printer?

I was talking to the owner of FGC/HGC who asked me a question I couldn't really answer: - Are there any modern printers that will work with the Oric ? Any ideas? The last new printer I remember working was the old Canon BJ10. My HP 950 should have worked but I couldn't get it to print with an Oric. ...

Re: Oric tape loading

Oh yes, I'd forgotten about the progress bar. I guess my initial thoughts were whether the main code was OK. Has anyone compared loaders from other 6502 computers? Is there room to try an alternative loader without messing up the rest of the ROM? If the main problems are hardware-related it would se...

Re: Oric tape loading

I think Peter Halford said the routine was copied from some old reliable code so it shouldn't be a problem. (So maybe it is more a hardware issue.) But I think there could be a few tweaks to improve how it looks. I mean, we just get a loading message and then after along wait it either works or cras...

Oric tape loading

Everyone knows the Oric tape loading code isn't great - but why has no-one rewritten it? With RAM overlays and such you'd think there was scope to rewrite the code and give Oric a good tape loading routine. Or is there just not enough room ???

Re: Microdisc Service Manual

I'm going to have another look at it later. I don't think there is another wire. It may be a bit of resoldering that you are seeing. I have to do some more testing swapping power supplies for the drives to see if the Opel will fire up then. It's a bit difficult as my system sits under the monitor, s...

Can't tell from the transformer, but the LM340T regulators are specced as 1A each. Note, that's only when heatsinked properly, sitting like that, they will just burn up and shut down!
They are normally bolted to the case with some thermal compound.

Re: Microdisc Service Manual

Steve: I don't know what the wire is you're advocating, but the annotation specifically shows Pin 34 of the ORIC expansion connector must NOT be connected to Cumana local ground. "+5V common link on PCB, NO GND LINK". It looks like someone has "added the missing wire" from ground to P34 (is that th...

Re: Microdisc Service Manual

If you measure between the middle leg and the one nearest to RV1 on the board I'm getting .925.
Make sure you have this little wire in place.
