Re: Logic Analyser on the Cheap

Recently I was trying to diagnose my... diagnostic cart with a Logic Analyzer (Logic-8 clone). I did it, but not in the way I'd like to. All lines were looking legit on the LA software, but I realized that, with probes connected, cart behaves differently. So I started disconnecting the probes, one b...

Re: Lead-free soldering

I find lead free solder fine for a new stuff, but not for repairing old one. I would't care about inhaling lead, as it almost doesn't vapor during soldering. What is really toxic are the vapors of flux. I'm using Sn60Pb40 with SW26 flux and lead free Sn99Cu0.7Ag0.3 with 1.1.3 flux (1.1.3 a.k.a. SW-2...

Re: FOR SALE STF/E KEYBOARDS (UK)

I got keyboards form Chris. Some were very dirty, but all except one were working, yet most of them required re-soldering of a mouse port. It was a good buy. I've made some observation - one of these keyboards had a base frame with additional "bumps", yet all had the same PCB and all were CA070138-0...

Re: Is this true ?

I've heard about it some time ago, I think they called this ACTA 2 or ACTA bis. More or less it concerns copyrights, and intellectual property. It may be a trouble for people using parts of others' work or image, making all kinds of remakes and covers.

Re: Whats all this EORI HMRC nonsense now ?

Never heard of it (EORI) in Poland. I'd say more, most "private" parcels from China goes to Poland, without custom fees, nor taxes... unless you go for UPS delivery, which recently isn't much faster than AliExpress Standard Shipping (about 1 week), yet way more expensive. With them you have custom f...

Re: Back to Atari; finally!

You just put an HXCSDFE.CFG for the Normal Mode in the root directory of your USB drive. You may modify settings in this file by loading it into HxCFloppyEmulator.exe (SD HxC Floppy Emulator Settings _not_ USB HxC) and modifying it. Some of the settings you may override in the OLED menu (press and h...

Re: Back to Atari; finally!

According to my knowledge the disk change fix is not required for current HxC firmwares. Also - having OLED and rotary encoder, there is no need to use slots (nor the fileselector loader) anymore, you directly chose a disk image file.

Re: The strange case of the non-running games.

XCONTROL for sure causes RANDOM crashes on Petari's HAGA games. One time they will work, other time they'll freeze, and yet another they will crash with 2 or 4 bombs. So I'm sure XCONTROL can't be loaded in order to play HAGA games. Klaz's HDD conversions don't have such problems (but there is not m...

Re: The strange case of the non-running games.

Petari's loader (called HAGA) doesn't like to have any resident programs in memory. Sometimes it will work, other time it will crash. For me the ultimate solution was to use X-BOOT with a "clean" config for Petari's games. There can't be any accessories, nor AUTO programs it barely tolerates ICD HDD...
