David,
I am sure that I am speeking also in the name of the whole list if I simply say: thank you for coming back and be welcome!
Your contribution (to Newt-hardware as well as for the list) is highly appreciated!
Because of the total lack of info regarding yor departure of course a lot of rumours circulated in the past.
But let me say personally that I am very happy to see you back and not "only" back, but back with new and great ideas!
Let me add one point to the redesign of the SER-001:
- maybe it is possible to take into consideration a Mini-DIN connector with higher quality (the plugs tend to have a loose contact and this is the reason for several contact problems - as reported in the list)
I know a little bit what I am talking about if I vote for a completely populated SER-001+, where it is up to the user to decide if he wants to replace the crystal on his Logic board or not.
It makes it much easier for you one one hand and on the other hand (I am almost 100% sure) as soon as the first positive test reports are circulated - EVERY Newtonian wants to have this feature! (And I am a potential candidate to test the new SER-001+)
Changing the clock speed automatically and combining the circuitry required for this function with the SER-001 driver is a great idea! I am sure the most of the list members will like it!
I am looking forward to hear more about the SER-001+ and its progress.
Again, welcome back, David!

Betreff: [NTLK] I'm Back!!
Dear Friends,
After much deliberation, I have decided to return.
My recent departure, though abrupt, was necessary.
The details are private although nothing to do with
being sued as some have suggested.
I will be creating another batch of SER-001's.
They will be redesigned to address the issues that some
of you have experienced.
This will include:
More robust internal connector.
Countersunk holes.
All components on bottom side.
I am also experimenting with a method of changing the clock
speed, on the fly, to facilitate serial comms. Basically,
the clock will automatically switch to 'normal' speed for
the duration of the comms, then revert back to 'turbo' without
user intervention. The details have yet to be worked out.
Unfortunately, this would mean removing the crystal from the
main logic board and soldering wires to various points.
Piece of cake for Dr. Newton etc. but a problem for the
average user.
I really like the idea of making just one board. So, perhaps
I could make an SER-001 with the additional circuitry not populated.
It would work just as all the others out there. Or I could
populate fully and call it an SER-001+.
Please, let me know what you think.
As far as my website goes, it is back up in a limited fashion.
I am working on a better one (as soon as my FP2000 skills are honed).
If anyone needs some mounting screws then give me a shout.
Victor, I know you do!
Regards,
PCBman
