The Sinclair QL Forum

Got any further on this ? Would be really interested to see your design documentation and any other info you've got on your prototype. Hi Dave, fortunately I have had a bit of spare time early this year so I have made quite a lot of progress on the driver which is the biggest missing piece of the p...

Hi Paolo, thank you for your kind words! It's just a quick hack but hopefully useful for someone.

Cheers,
Petri

Great bit of programming for original BBQL
Thank you very much

And just in case somebody is interested in the ASM source code for the xmodem bit, it can be downloaded here. Compile using George Gwilt's Lite Assembler. It's a quick and dirty version so probably has quite a few bugs in there.

Hey, it's been a long time but there's been very little time for hobbies lately :( Anyway, I got some spare time this weekend so I decided to implement the xmodem receiver in assembly. It's now faster, more reliable and first copies the received binary to memory to prevent errors during receiving du...

Hi Rich, yes, the alternative method would be to respr and poke, but since the initial superbasic program is there for the sole purpose of transferring QTerm (i.e. a proper file transfer program) over I couldn't be bothered to elaborate on the trivial implementation :) I'll be happy to share the cod...

So I tested a few things. The constraints (128k black box / only microdrives) are rather severe, though, so results are not exactly stellar :) First off, copying binary files with "copy" command direct to microdrive from the serial port seems to be a non-starter. Small text files (such as ...

Mr vanpeebles seems to be reporting there's also 512 sram on the Qubide clone card so that would sort you out pretty nicely.

Well, that certainly makes things more interesting I'll see if I have time tomorrow, I might create a quick hack of an Xmodem receiver implementation in SuperBasic just for giggles. That should get you started.

Might be a good idea to get in line for the hopefully upcoming next batch of qubide cards?

Do you have a memory expansion or is it a 128k machine?

Well, so far I have not been able to do a successful copy of qterm_cde binary file using a plain old "copy" command. I get a corrupt file even at 1200 baud when copying directly to microdrive. Funnily, I was able to copy the related basic files in the distribution without problems. Did all...
