As requested by PM, here is the 1pinTV file v1.08 with 80x25, no inverse, for use at 104MHz (6.5MHz). The same will also work for 96 & 100MHz although some flicker at 96MHz.

The new version adds a timing diagram.
Greatly improved VT100 speed·performance.
A new mode (now the default) calculates the parameters almost solely using constants in the compiler so the footprint is not expanded much (4 longs). Just select NTSC or PAL and the number of rows. Columns are currently fixed at 25.
v1.25 released to OBEX.
Rows and columns can now be selected and there is no screen·size restriction (except by the TV) as screen space is automatically allocated to the hub cog code plus the little extra for larger screens. At 5MHz NTSC 64*28 & PAL 60*32 both work quite well.
I have recovered some cog code space for further VT100 controls (later).
For those interested, here's a version of FemtoBasic modified for use with the RamBlade using the v1.25 1-pin drivers. There's a statement and function added for access to the SRAM that works as follows:
Mike, there is probably a way to still use the SD card and SRAM with files open. You just have to release the SD card (to force DO to be released by the SD card) after use. It is not necessary to close the file system. This is the way I used it in ZiCog.

This makes an easy 2pin debug terminal.
Enjoy

New feature includes the optional 1-pin Keyboard Driver using three resistors and 5V.
This is ideal for a simple 2-pin Terminal (mono TV & keyboard) of a Debugging Terminal or Debug Screen.

The early bird gets the worm but the second mouse gets the cheese.
SRAM [noparse][[/noparse] <address> ] = <expression>
Sets the specified SRAM location to the given expression value
and
SRAM [noparse][[/noparse] <address> ]
Has the value of the specified SRAM location
Note that you can't access SRAM while a file is open because of I/O pins being shared between the SD card and SRAM.
