Re: Atari STE: Drive A: diplays files with cryptic extensions

Not really. The STE is marginal as built and the drift in components with age could have just pushed it over the edge. There should always have been pull-ups on those lines, but it just happens that they have floated high enough to work by a happy accident.

Re: Splitting a big file ont pieces

It may be best to zip (or otherwise compress the files), uuencode and then split.

At the other end you'll need to somehow concatenate them together, uudecode and then unzip.

The uuencoding make them safe text files which you can more easily munge without destroying the content.

Re: uip-tool

. i.e. the cumulative propagation delay through the chips is just too high if the voltage is precisely 5V but sneaks in if slightly higher. Any chance you could verify that by swapping the chips for LS versions? I'm not sure you'd be able to get LS chips in SOIC packages and I wouldn't be confident...

Re: uip-tool

I'm thinking that it has to be electrical given the behaviour with my STE and different power supplies. It works the Atari one (which overshoots on the +5V line a bit) but not with the Exxos one which provides a very accurate (and less noisy) +5V. Maybe the board just needs more that 5V. I know my ...

Re: uip-tool

I think that PAK changes some details about signal timings when accessing the romport. Netusbee works perfectly in Falcon with 030 and even better with 060 at 100Mhz. It works in some TT's. I wonder if this is about the 16Mhz and 32Mhz versions? Having leant a lot this week about decoupling caps an...

Re: uip-tool

e.g. on my STE, it will work with the stock power supply but not with the Exxos power supply which has less noise and better voltage control. i.e. the hardware only just about works under the best of conditions.

Re: uip-tool

Knowing the failure modes of the NetUSBee on the TT, the "write using read" is failing and so the ethernet interface isn't doing anything. The other failure mode I've seen s the system not being able to read the MAC address and getting all zeros. NetUSBees are extremely finicky and will stop working...

Re: GOEX for ST in the making

Yes, creating and using new floppy images is a right pain. It would be excellent if there were a button combination to generate a new blank image and switch to it, which you could then format in the usual way.

Re: GOEX for ST in the making

Actually FlashFloppy itself doesn't use HxC format for the floppies if run in native mode. There *IS* a compatibility binary you can put onto the drive to allow it to operate in an HxC-like way, however, but it's optional (and I prefer not to use it). In native mode it uses raw disk images, which su...

For cleaning the contacts without damaging them or pushing them too far apart I find printer paper folded twice to be about the correct thickness. Soaking this in a bit of IPA (not ale :-) ) and gently and repeatedly pushing the flat paper edge into the slot will gently wear off any oxidation withou...

WANTED: SF314 (long button, non-standard connecotr) drive mechanism (or Side 1 head unit).

I'm currently looking for a working or non-working drive mechanism for a long-button SF314 drive. (Mechanism model number: C070353-001) Basically, the side 1 head is damaged and I'd like to replace it. The specific drive model is not the same as the long-button STFM drives as it has non-standard dat...

Well, after my previous message Brad said that they'd found a couple of ST(M) badges in the zip-lock bag with the STFM badges in it and he said that he'd put those in the order instead... Fantastic!

Except...

When the parcel arrived today they were just SFTM badges. Oh well.

Hmm... It's tricky dealing with the vendor, even if he does read your e-mail. Also the shipping charge would be HUGE! Still, it's an option.
