Icky - Progress

[PaulJ]

Yes, I've decided to wait but its painful.. I'm not a patient person. I can check out the floppy using the diagram cart so I'll do that.

I can confirm that we do indeed need a floppy connector board just like the monitor connector one.

External floppy works with a patched cable.

Pin out between the two is as per my previous diagram (below - remember STF board is on the right):

This is the multicoloured adventure I had getting this to work

Right, that's two things for me to unsolder tomorrow then :D .

Might see if I can make a patch board with some prototype board. Will post a pic if I get time (And find the psu for my external drive.

Careful unsoldering. Don’t do what I did and pull a track.

I had a look at using prototype board but I couldn’t find any with the right hole pitch.

Hmm.... I wonder.....

It does....

So going back to my list of things to do:

• COMPLETED - Scart Cable - flicker and bounce gone with cable update. Cable clean-up also sorted out the sound a while back
• COMPLETED - Un-f*ck board installed
• INVESTIGATING - Seeing slight noise scrolling up the screen. Modifying cable to improve grounding and shielding did not fix. Going to try out suggestions from Exxos.
• COMPLETED - Keyboard / Mouse - getting key repeats and sometimes when moving mouse. ACIA area (DILs) were poor in quality so I replaced and checked the dataline patch. In addition made a smaller pin8 patch socket instead of the extension cable I created. Adding longer lines to the keyboard requires more juice to the board but repeating has gone
• PATCHED - External Floppy Drive. Tested after patch wires in place. External floppy works. Now needs a STF REMAKE FLOPPY UN-F*CK BOARD. What this has allowed me to do is test out SpectreGCR which shows External Floppy and ROM Port is all working as expected
• COMPLETED - RS232 - is working. Helped with DiagRom and Diag Cart but noticed it got corrupted when board has more power applied i.e. with keyboard, mouse, floppy etc board takes more amps. This has gone away with the ACIA clean up so something must of got cleaned up on the way.
• INVESTIGATING - ACSI - Plugged in a while back and it occasionally saw the Megafile but no drive. Now its not even seeing the Megafile. When booting with Megafile attached now at start it doesn't recognise the floppy drives
• Parallel - No tests yet have realised I have no old cable or a printer to connect it to. May be one of the others can test if they have a suitable printer etc
• Midi - No tests yet will get round to this soon

Now needs a STF REMAKE FLOPPY UN-F*CK BOARD.

Should be able to design that tomorrow.

I've actually had the problem recently with when hard drives were connected the floppy drive would stop working.. was a bugger to find..but...

I'll give that patch a go to see if it fixes the problem. Need to test Megafile on STFM though first to make sure it is behaving correctly

[Icky]

but have noticed it gets corrupted when board has more power applied i.e. with keyboard, mouse, floppy etc board takes more amps. RS232 started to corrupt - need to reconfirm this.

OK.. its possible the floppy power needs a bulk cap on its cable...

So today I noticed that sometimes the HxC2001 stutters under load with other devices. Going back on the thread and reading this I put in a bulk cap on the floppy power line. Took one from the donor STFM a 1000uF. This stopped the HxC2001 stuttering.

Nice find! So will probably add in some 100uf ceramics around the updated board..
