;- History: Jan 2020 - Initial version.
|
|
; May 2020 - Advent of the new RFS PCB v2.0, quite a few changes to accommodate the
|
|
; additional and different hardware. The SPI is now onboard the PCB and
|
|
; not using the printer interface card.
|
|
; Jun 2020 - Copied and strpped from TZFS for BASIC.
