Re: Running Cport from Win1_

Don't run the disassembling first phase again, just run the turbodischarge1_bas program, and use the cport_codes file supplied. Many thanks indeed Martin, that helped a lot. Using the codes file you supplied, and the updated version of the TurboDisCharge1_bas decompiler, I got about 14,500 lines of...

Re: Sinclair QL Factory Test Jig

I think Maplins used to sell them along with the switches that would solder directly onto a PCB. There is a ZX81 with custom k/b on ebay that looks like it has the same switches, but he wants silly money for it. I'll find some spares one day. I found the Maplin instructions for building a ZX81 keyb...

Re: Sinclair QL Factory Test Jig

retrobrighting the buttons… I’m missing one, so if anyone knows what type/make of mid 80s button they may be, please let me know. The buttons look like the ones that came with a ZX81 keyboard kit I had. There was a clear top which clipped onto the top of the key, and you could place a piece of pape...

Re: Running Cport from Win1_

I have been having a look at the Cport file this afternoon. I have attached an update zip file. It is just the files I have altered today. When you ran the program, and it stopped on you. All of those warnings at the top of the screen are relevant to the problem. All of those "-1" entries ...

Re: Running Cport from Win1_

The Discharge programme stopped at line 27430, with error message: At line 27430:1 assignment can only be a variable or array element Looking at line 27430, shows variable assignment: FOUND=0 I have th...

Re: Running Cport from Win1_

Thanks Martin (and apologies for spelling your name wrongly previously!) My original version of disCharge_bas was 17/05/2019 and this is 12/08/2020 so a much more recent version. This time I get a better decompile, but it bombs out eventually, in the full decompiler, with " Unexpected code $A2...

Re: Running Cport from Win1_

I did try to use Martyn's disCharge to decompile Cport -- why not -- but it barfed when running the full decompiler, with an error along the lines of A9A6 or similar. No codes file was created. I was thinking it would be good to ressurect the source for Cport -- in a manner similar to the hard work...

Re: Steve Davis Snooker on Super Gold Card

Looking at the numbers supplied. You could try loading the game into into Qemulator, but don't do the CALL then SBYTES flp1_something,184320,66704 (that's if I did the sums right :? ) This should save everything as one big block, ready to go. That you could LBYTES at 184320 in the Goldcard then CALL...

Re: ql printer repair woes

Out of curiosity. Do the suspect coils look like burnt, or anything?

Re: ql printer repair woes

Bit of a long shot, (well a lot more than a bit) Try re-soldering the connections on the back of the printhead, in case there is some kind of dry joints after all the years.
