Short video of it working, really straightforward, I do like it. You don't need to keep going to the menu that's just me not remembering , with time, I'm sure you never use the menu option sectzap.mp4

Yes that fixes it, this is what I did, sort of similar:- not sure if you remembered you don't need to specify a device to close a channel, so safer way is to just close it, then provide the parameters to open it. 8175 POPEN LDX #$70 8176 LDA #CLOSE 8177 STA ICCOM,X 8178 JSR CIOV 8179 LDX #$70 8180 LDA #3 8185 STA ICCOM,X 8190 LDA # <PNAME 8195 STA ICBAL,X 8200 LDA # >PNAME 8205 STA ICBAH,X 8210 LDA #0 8215 STA ICBLL+1,X 8220 STA ICAX1+1,X 8225 LDA #1 8230 STA ICBLL,X 8235 LDA #8 8240 STA ICAX1,X 8245 JMP CIOV

Nice little utility, clean assembly in MAC/65 (once I got rid of the tabs ) copy paste into Altirra got messed up with them in. Only issue I found was if you print a sector, it only works for the first time, after that you get ERROR 81 Easy fix, just do a close of the channel before you open it. Would have used this back in the day, easier to load than Disk Wizard and does most of what I would have wanted. 👍

Doesn't look good to me, you should only get conductivity in one direction between Base/Emitter and Base/Collector. BTW. when fitting a new unit don't forget to use some heat sink paste between the back of the transistor and the heat sink.

Looking at the front i.e. not the surface touching the heat sink. Pin 1 = Base Pin 2 = Collector Pin 3 = Emitter To test this put meter on ohms range red lead to pin 1, black to pin 2 = low reading ~0.4 to 0.9 red lead to pin 1, black to pin 3 = low reading ~0.4 to 0.9 Black lead to pin 1, red to pin 2 = Out of Limits (no reading) or "High" depending on your meter Black lead to pin 1, red to pin 3 = Out of Limits (no reading) or "High" depending on your meter BU508.pdf With regards to the package, unless the specification in terms of voltage/current/frequency are the same and it's physically going to fit on the heat sink, you will need an original part.

just had a look at the MADS documentation it looks like you use EQU or .DEF for global variables, have a look here for examples https://mads.atari8.info/mads_eng.html#labels

if it's ca65, labels must have a : after the name lda stuff and #1 bne l1 lda #0 sta $cb l1: lda #3 sta $cc RTS .endproc stuff: .byte 0

I think you need 764, have a look in Mapping the Atari

Just testing you , passed with flying colours

many thanks @calimero I managed to get a static IP address, I looked through the code and found where it created the file (root of the C drive UIP.CFG) not where I run it from, I edited it with the right addresses, reloaded the program and now see the IP address I wanted, back to PC, put address in browser and hey presto I get connected and can see all my drives/files. I copied a test file to the ST and it worked a treat, this is going to make things so much easier now. Do you know if there's a way to copy multiple files from the ST to PC, PC to ST is easy (and fast)

Of course, makes sense, will give it a go later, one other thing, it says you can specify a static IP address by pressing F1, if I do this it pops up with either a different address or offer a static with a prompt, however as soon as I press any key it exits the program, so can't choose a static address, also doesn't create a file on the hard drive which the instructions say it should.

I ran this and it appeared to show everything is ok. Removed Sting from Auto folder, ran this and got a DHCP address, however I can't find the web interface shown by the author, I've searched everywhere on the web site, but can't find it. I tried a ping to the address shown on my STE, but no pings were returned. From what I read there's a very complicated set of instructions to get a set of tools available in Cygwin, I tried to install, but the install script insists Cygwin is on your C drive (mine is not) and there doesn't appear to be a way to change that.

Unfortunately all the diagrams I have are so poor I can't make out the name of the resistor, You could continuity check from pins 2 and 4 to the CPU HALT pin. If that's OK it looks like there's a break on the pullup resistor tracks/solder joints. Need to find out which resistor it is, I'll see if I can find a better diagram. Edit: It could be R75 from a 520ST diagram

@calimero many thanks, this is the main reason I wanted this device, floppy drives unreliable and no success with a GOEX drive either. I did see this and downloaded it, but wasn't sure what it did, I was concentrating on Sting.
