STE DUALTOS BOARDS NEW BATCH
Posted: 22 Aug 2017 22:56
The next run of the STE DUAL TOS boards is in motion. These will replace the previous blue boards. These are a fraction smaller but as basically the same as the previous blue boards.
These boards hold TOS1.62 and TOS2.06 and are available in most languages. Selection is done by a simply jumper link or a toggle switch (not supplied).
The only real change is the TOS select jumpers have gone from 3 pins to 2 pins. Also now there is a pull up resistor. So when the jumper is "missing" it will default to the upper TOS bank in the ROM. Connecting the 2 pads will select the lower bank of the ROM.
