Re: gravitar or black widow prom needed

I've had good luck with this guy...He's in Canada...
HobbyRoms.Com
He recently did four PROMs for me (3 x 82S129...1 x 82S147).
Total bill, including shipping from Canada to USA...$30.00.
Can't beat his prices..

  Subject: VECTOR: gravitar or black widow prom needed

  I need a prom made that goes in a gravitar (or black widow pcb). I normally have Bob Roberts make my proms but he no longer has a programmer that will make this. The following is the information that I recieved from another member of the archive. Please feel free to email me your price and I will paypal or send funds right away for this prom. Here is the info:

  Here is the code for the other address decoder chip R1

  This is the code for chip at location R1.

  Address 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F
  Data FD FD FD FD FC FC FC FC FC FC FC FC FD FD FD FD

  Address 10 11 12 13 14 15 16 17 18 19 1A 1B 1C 1D 1E 1F
  Data FD FD FB FB F7 F7 EF EF DF DF BF BF 7F 7F 7F 7F

  Use a 32x8 PROM chip - 82S123

  Program the above code starting at chip address zero.
