| 815.1 | Add-on boards | KALKI::LANG | | Mon Apr 02 1990 10:02 | 3 |
| I don't know about modifying a 520ST, however, there are a few vendors
of add-on boards with lithium battery backup for the clock chips.
Software loads the "board time" into the atari at boot time.

| 815.2 | cheap: keyboard processor time | MGOI03::FALKENSTEIN | | Mon Apr 02 1990 10:48 | 10 |

You may buffer the clock in your keyboard processor with some
rechargable batteries and a small circuit to recharge them when
power is on. On every power-up the keyboard clock time then must
be loaded to the system via a little program in the auto-folder.
This is the cheapest solution, but accuracy isn't that good (good
for about 3 weeks, then you have to reset the time).

| There's also "Z-TIME" (about $40, U.S.) and the ICD host adaptor for the
hard disk includes a non-volitale clock.

| 815.5 | st schematics required | KERNEL::ROBB | | Sun May 31 1992 16:47 | 17 |
| Has anyone got a set of atari prints they could let
me have a copy of?
I connected the battery backup as in this
article. (schematic kindly supplied by Bernd)
The problem I have is that the battery only keeps the time
for a day even on fully charged batteries.
I would like to do a little troubleshooting before
I give up on it and spend some money on a plug in
clock.
Ken Robb.

| 815.7 | It's an STE | COMICS::ROBB | | Thu Jun 04 1992 10:41 | 6 |
| Bernd,
It's an STE but I guess most, including the keyboard, will be the same
as the ST FM.
