Golden Tee Betabrite LED Ticker display. PC Connect Software......Help
MonMotha:
The text was dynamically updated by Incredible Technologies as part of their network for the games. The display board apparently also served as a sort of "port multiplexer" - the modem was connected directly to it (heck, there were even provisions for the modem to be built into the board, but those spots were always depopped). There's a flash chip on the board (Intel, IIRC) that probably stores all the current data for the device to display.
There's a way to move a set of resistors around and make it boot off that flash chip, but then you'd need a way to program it. There's no JTAG interface or anything to bit bang the address/data bus, IIRC, so that may not be an easy task aside from a bootloader.
That and figuring out how to actually work the front panel part is about as far as I got reverse engineering those things before I got totally busy. I've had other things way higher up the priority list ever since. Heck, I've been working 45+ hour (billable, let alone the administrative time) weeks for the past month or so.

actually I think it does have a JTAG. I have a dozen or so boards at work of varying revisions. i believe some have a JTAG.

unfortunately the golden tee signs don't use the same protocol as the betabrite signs. it's something custom by IT.
last i heard someone was attempting to build a controller to drive the display. that was a few years ago now.

hi
it is totaly coustom s/w
it is driven by 1 of the on-main-board xilinx
which is a programble gate
then it is tied to a rj45 jack through a lt1134acsw
all is controlled via u22
the s/w was/is controlled by its-gaming
same pga golf
now up here in the great white north
the last location the unit was in berfore they pulled there server will still be displayed
with that all said
u can get a fresh eprom from the mfg..$25.00
the protcol is reversed serial
u can chat the sign >done it did it<
as they are coustom eprom's >27c512<,u can buy 1 and play away
what u get for $25.00 is the led lay out :matrix: and routing
for it's-gaming it is rj45 to rj45
