Bare S100 Prototyping Board ALTAIR 8800 IMSAI 8080
Item History & Price
| Reference Number: Avaluer:7111889 |
You are bidding on a Blank Prototyping PCB with buffer chip circuitry (no chips included).
Gold Finger S-100 edge card connector.
Add 74LS245 buffer chips to Address, Data, Status and Control bus.
Change direction for CPU or Peripheral board.
~4, 000 free holes.
Traces included for Buffer chips and voltage regulators.
12V and -12V regulators can be ignored and the space around them reclaimed (cut or ignore the traces/pads with power)
The on board data IN/OUT bu...s is already connected, but those traces are easily broken to provide separate IN/OUT or a 16bit data bus.
Address bus up to 24 bits is buffered (as per IEEE-696)
4 holes around board, can be used for card ejectors or stand offs.
Listing includes: Blank Board as shown
The schematic and board layout is available on the internet at S100computers.
