<>> panel. Does anyone remember other front panel S-100 cards besides MIT

<>Yes, the Byte-8 had a front panel with, I believe, a hex keypad and a tw
<>digit 7-segment LED display.
Godbout.
Equinox_100.
<Was that just a display driven from a boot ROM or was it a real front pan
<with displays directly driven from the bus, examine/deposit, single step
<etc.? Usually a hex keypad meant a simulated front panel (CPU actually
<running a debug program in the boot ROM). A true front panel needed 16 L
<or 4 hex digits for address, 8 LEDs or 2 hex digits for data, and at leas
<status LEDs for bus signals (SINP, SOUT, MEMR, INTA, etc.).
Most were "simulated FP" though most offered better than real front pannel
abilities. A few were hybrid, IE: the leds really did indicate what was
on the bus and the cpu only ran the rom code needed to perform the needed
actions and stopped.
<All the panels
<I have seen also had an extra 8 LED latched output port and sense switch
<input port.
Altair compatability hack. The sense switches were also port 0FFh so the
software could read them.
