DO NOT USE MOBILE / CGNAT DEVICES WHERE THE IP CHANGES CONSTANTLY!
At this time, it is unfortunately not possible to whitelist users when your IP changes constantly.
You may inadvertently get banned because a previous attack may have used the IP you are now on.
So I suggest people only use fixed IP address devices until I can think of a solution for this problem!

Re: BOOSTER 2.2 REVISITED
16MHz ROM access working :)
Next I need to build the new ROM board and get TOS206 running..
The bars which hold the PCB are pretty high up off the heater, so the heat on the PCB is about 100C when the bed is 400C. So I put the PCB directly on the heater, now its about 200C. Solder melting fine now... just takes a long time to cool down on its own. At least the PCB oven has a fan to cool down quicker.. but at least its looking like I can solder these SMT sockets without melting them, so that's the main thing :)

Re: BOOSTER 2.2 REVISITED
I am building 8 of the new ROM boards (thats all the PCBs I have) With the intention of them being sold with the booster.
I have hit a small brick wall in terms of the GAL's again :roll: (ran out of GALs!) . Currently even though pin 4 (powerdown) is configured as a IO pin, the chips do not function in the booster board. But I had this problem before anyway. I think my programmer is somehow enabling the powerdown feature even though it is not supposed to be. I was talking to Atmel support a few years ago about this problem, and they pretty much thought my programmer was causing the issue. So I have ordered a new programmer, to see if I have better luck.

Re: BOOSTER 2.2 REVISITED
Only just got home, but new programmer waiting for me :)
I got the same one as Icky...
www.amazon.co.uk/gp/product/B07B985LBS
Quick program of the ATF and the booster is working. So my old TOP3000 programmer doesn't seem to support the ATF properly it seems :roll:
Now to order a stock of the Atmel chips... :)

Re: BOOSTER 2.2 REVISITED
Is that a TL86? If so it works really well and very easy.
If it ain't broke, test it to Destruction.

Yes that's the one. Very happy with it here.

Re: BOOSTER 2.2 REVISITED
Been busy past couple of days building up some V2.3 booster and dualtos boards...
Waiting for the new GAL's & ROM's to arrive now (will be here tomorrow).
