More Progress and more questions.....
Well, after some much needed support off Zaxon (thanks!) I copied the sd2iec files to a TDK 2Gb SD (non-SHDC) card bought for the job, along with a couple of .d64 games d/l'd from t'internet. On turning on, it was exactly the same, red light, and no device found.
I then resoldered the whole thing, and got the same result
So, I 'borrowed' my camera's 8Gb SHDC SanDisk SD Card, copied the files to it and ..... success... but only if I put the SD card in AFTER I turn on the C64. If I do it before, then no files are found. It works EVERYTIME if I put the SD card in AFTER booting. I can load sd2.prg and load games etc.
Obviously, short term, this isn't a problem as I add to my library, but, eventually I want the whole thing to be internal so I ask....
(1) Is this normal ?
(2) Is it the SD card (Zaxon recommended a 1Gb card but I haven't got one yet)
(3) Is the device fussy with SD cards ?
(4) Surely there is a better file browser than sd2.prg - its a little 'ahem' BASIC isn't it ?
(5) Will this thing run quicker with my "Power" interface attached (I haven't got it with me to try as yet) ?
All help, as ever much treasured and appreciated .....:help:
