| John,
Can you also put me down for the TIL311 board if it’s not spoken for?
Ian
I have only one each of the HP, TIL and LED bars left Ian. That’s all. If the is a need (i. e. more than one of each of the above) we can order more. John John, Do you also have any of the daughter boards available? Please put me down for 1 board. Now that the S100 bus XVGA video board (http://s100computers.com/My%20System%20Pages/VGA%20Board/VGA%20Board.htm) has gone out to everybody, I would like to announce our next board… It’s a V3 version of our tried and true SMB (System monitor Board). The original board is described here:- http://s100computers.com/My%20System%20Pages/SMB%20Board/S100%20Bus%20SMB.htm The following changes/updates have been made to the board:- - The was a minor error on the above V2 board (pin 5 of U32), this is now corrected.
- There was a report of the TMA 0-3 switch circuit was not working reliably with the 80386 board at high speed, this circuit has now been completely replaced/simplified with a single GAL.
- An Intersil ICM7216D chip has been added along with 3 new Digital displays to continuously display the frequency of the bus master clock speed (PHI) in MHz.
- A circuit and LED bar was added to continuously display the bit pattern of a user defined output port. (default, LED Diagnostic Port 05H).
- A circuit was added to trigger an interrupt if the S100 bus ERROR* signal (pin 98) is activated.
- A series of jumpers was added to easily attach a logic probe cable (such as a USBee or Saleae unit) for hardware debugging.
- The LM323K 5Volt, 3Amp regulator can be replaced (in the same footprint/space) with a Pololu 5 Volt , 2.5 Amp D24V25 Switching regulator.
- Almost all chips from the V2 board can be re-used on the V3 board. Only the ICM7216D, 3 Digital displays and GAL 22V10 are new.
Please see the bottom of the above page for more information. I will be sending off an order for final bare boards in the next few days. If you would like one or more boards please let me know (preferably by e-mail). The usual arrangements ~$15/board + postage WHEN you get the board via PayPal.
