Hi Guys,
The 8080A CPU boards are here! They look good! I'll put one together soon, for now I'm still working from the prototype to make firmware.
Cost of boards are $20 each (CPU or Prototype board).
Shipping options are:
-USA Shipping (sending next week)
-Flat pack $5 for 2 boards, $7 for 3 (boards wrapped in construction paper and shipping tape).
-Flat rate medium box, for $12.35 (up to 9 boards)
-Canada shipping -can ship Wednesday, no shipping on Canada day (Tomorrow)
-to US $7 for 2 boards, $9 for 3 boards
-Italy
-Fabio, to Italy, $16 for 3 boards.
-Australia
-Malcolm, send me your address, I'll get a rate for you.
Please see list below for orders received, feel free to change quantities.

There were 5 orders for LM323K TO-3 voltage regulators, I only have 15 available for sale but 4 are pull's.
I will give them a quick test to be sure they are working. I think it's only fair to split them up equally in the group.
3 regulators each. Please include $2 for each ($6 total). I don't know yet how it will affect shipping cost (Flat rate medium box obviously won't be affected). Since I don't want to go back and forth to the post office, I'll ship them and request the difference later. Paul Birkel, since you're only buying LM323K's, kindly include $5 for shipping and we can balance the difference later, ok?
Finally, see below for a picture of the blank board.
PS. Note, the 8080A chip is the only chip with pin 1 to the right.
Also, you do not need to install all the 1488, 1489 chips. By installing only B3 & C2, the serial ports will work TX/RX, RTS/CTS. If you need DTR and/or DSR, install A2 and/or C3. A2 will also give modem signals (DCD & RI) to COM1. B2 is for Modem signals to COM2. There are 2 connectors for the serial ports. Top is 1:1 and bottom is IDC. This should accommodate the majority of RS-232 connectors with ribbons. If need be, you can cut all the traces between these two connectors on the bottom. Most of the driver/receiver chips are traced to the IDC connector from the top of the board. Then you can install your own jumper wires to configure the 1:1 header to your own needs.
Use open frame sockets for 8250's, so you can hide a decoupling capacitor beneath the chip.

Josh Bensadon
