10 years ago I have tried to implement Waveshare USB module to Vampire accelerators. It is nice SL811 USB board and more details about it can be found HERE. Module is discontinued but this shouldn't be problem as design is relatively simple. In theory this board should work directly on Amiga clockport except that one signal INTREQ should be inverted. All pins of SL811 are 5V tolerant. Chip created lot of controversy inside retro computers world and many reported that chip is slow and full of bugs. But anyway I wanted to try it. The same chip is also used on Thylacine USB. Very good progress is made by ezrec with his Pathway. More info about it can be found HERE.
Idea I had was to use this small module as an cheap upgrade for Vampire V2 accelerators but unfortunately several problems occurred and right now I am certain that Waveshare USB module I got was never working. Last few days I have performed several more tests on my Amiga 1200. First I have used Vampire 600 V2 accelerator as a bridge between A1200 clockport and USB module and couldn't get it work. Code I have done inside to make that bridge happen is really simple so I couldn't make mistake there. Such bridge is also made for the purpose of learning because that way I could see signals with SignalTapII and modify something if needed. Then I moved USB module directly to Amiga clocport and only inverted INTREQ signal. Still no luck with Poseidon and Pathway drivers. But, this is not end of the road. I have already ordered SL811 chips and will try once more because this is one of the things I have started and never finished. Simply I have to do it and see where we can go with this. Once I get it working, can I move it to use SPI or can I learn enough to move to more advanced chip. Let's see what time brings and story will continue when I get ordered parts.

A1200 with SL811 module

Some days ago I have decided to ensure better support for Vampire V2 series of accelerators with detail description of each product, tutorials and download sections. So far we had support over wiki.apollo-accelerators.com but unfortunately we had to cut some costs and support there had to be closed. From now on pages for support will be hosted here on this website who had different purpose before with more informative and research character. Making support on the level I want to be done will take some months and I hope that everyone will be patient but at the end we will have quality base of articles who will be very usable for end customers. Good product is nothing if you don't invest lot of time in tech support and do all the tutorials users want. As said this takes time because first old articles needs to be revisited and modified in order to explain usage of newer tools together with more updated picture guided tutorials. I have already started and first reactions of users are very good and this tells me that this is something they wanted. So far about 20 new pages is added and download section with SAGA drivers and cores is updated together with ChangeLogs. This is maybe 5% of what needs to be done so again I m asking for patience. Thank you

How to explain to my mother who want's me to paint the walls today that I have problems with my website where bots or who knows what or who are spamming me badly exploiting contact forms. Mom I need to integrate reCAPTCHA to my 20+ years old PHPNuke website. It took me all day but now is integrated, for now only to Express Interest Contact form but slowly we will get there. Simply this has to be done, same goes for walls :)

Going crazy PHPNuke won't accept HTML tag span style, in fact word style is the problem, blocked! I found where problem is but it is 1:38 AM now. DEAD tired! What an idiot I am right now, figuring out how I can't publish that this tag is not working under<> and same time I m witting that is not working!
Finally fixed nasty bug where Google Ads were not showing. I don't care much about ads for profit but for the purpose of indexing this pages this was very important. From thousands of lines of code it was very hard to find the problem. It was because lightbox and Google addsense js were interfering for some reason. Now they both work together! 5 days of work for this found!!! Fix in code within minute.
