Show me the hardware.
Since you asked. See board layouts on pages 2-5.
PTH Design
Besides being fully PTH, its a about 3.5 times smaller allowing it to fit into tighter inner case spaces, has 4x the ROM space, orders of magnitude faster transfer speeds (would peg SCSI-1), uses a modern interface - USB instead of PATA, supports optional direct PC emulation of the SCSI drive, about 1/5 the parts cost, and can be programmed using the same tools as the current S2I design (EEPROM programmer) as well as supporting in-circuit programming and debug.
No limits design
Using SMT much more is possible. Besides the ultra small board size with no over-hanging components on connectors, it could be plugged directly into a SCSI host controller socket with a female downward facing header. The header is also full reversible with auto-detection so that the board can be oriented either way. Could keep up with 20MHz single ended Ultra(narrow)-SCSI. And it could be mass produced on a kick start for under $50.
Just a couple options.
Hi
That's great! I look forward to seeing your board.
Now would you please start your own thread?
Deal.
