Hi
Honestly I have not figured this out yet. I am thinking that some analog of how we would do this were we all in the same small town. Think of a ham radio club that wanted to raise funds for a new repeater antenna. All the club members contribute to the fund, they buy it, install it, and they all use it. Part of the problem though is the N8VEM home brew computer project is definitely not a business and it more like a hobby club but just not well organized. There is no official leadership or treasurer and is basically an ad hoc group of random hobbyists that are globally dispersed.
What I am thinking about is basically every interested builder puts their money into a “kitty” and we use that to order the boards. The closest thing I can think of is to just mail a check, money order, or cash which I or some other builder then uses to order the PCBs. It is more hassle for everyone than PayPal but it avoids all of their problems too. I think any sort of electronic funds transfer service (Amazon, etc) has this problem. PayPal is just following the law to report when they see the number of transactions exceed some limit.
I am not sure of how WU or Money Gram works but if it involves posting bank account information that is a non-starter due to internet privacy concerns (really the total lack thereof). However there are some banks/credit unions that allow a sort of electronic paper check to be sent. The builder tells the bank to send the check and the bank/credit union literally mails a physical check to the specified address. It appears automatic and fully electronic from the senders end but the receiver gets an actual check. Sort of the best of both worlds if it is available.
Thanks and have a nice day!

Hi Andrew,
Would it just be easier to have those of us who want a board to wire you the money via WU or Money Gram?
Just a thought.
Best,
Joe

We are about to do another run of our popular S-100 Bus Z80 CPU V2 board. This board can run in systems (with bus termination etc.) at up to 10MHz. Apart from all the then common features found on many older S100 Z80 boards (and being completely S-100 IEEE-696 compliant), it had an extremely clever and powerful ability to allow the Z80 to address up to 1 MG of RAM in 16K "windows" within the Z80's address space. This is described here:-
Its primary importance is that it can be used to address greater than 64K of RAM for CPM3 and that it can be used to load/examine 8086 code at the top of the 1MG address space.
The new “V2” version of the board now has the ability to (under software control) dynamically switch between two 4K blocks of code in its onboard 28C64 EEPROM (or EPROM) yet still only occupy 4K in the Z80’s 64K memory space. This in effect almost doubles the size of a possible Z80 monitor. The extra code (currently being written) will include things like directly downloading binary files from a PC into the Z80’s 64K (or 8086’s 1M) address space.
In addition, the S-100 Z80 CPU V2 has the ability to use an external CPU clock from an external source (S-100 bus pin 66 aka NDEF3). This is essential for CPU to video synchronization for MSX compatibility particularly in games. There will be a corresponding ability to export a CPU clock signal on the next version of the S-100 VDP board although this could come from any S-100 board.
Current owners of the V1 board can just switch the IC’s to this new bare board.
The S-100 Z80 CPU V2 PCBs will be $20 each as per the usual arrangement. Shipping in the US is $3 for a single PCB and $2 for each additional PCB. Shipping internationally is $12.75 for a single PCB and $3 for each additional PCB. This is for the bare basics USPS first class postage with no tracking or insurance. The builder assumes all risk of delivery as per usual arrangement.
My preference is to sell these PCBs to vintage computer/home brew computer/classic computer hobbyists first but if there are any remaining boards I will put them on eBay.
Please send a PayPal to LYN...@YAHOO.COM with the subject “S-100 Z80 CPU V2 board” and I will reserve your board(s). I need about 20 pre-orders to warrant a manufacturing run. I will post more information as it becomes available.
Thanks and have a nice day!
