I'm pretty sure that the VAX architecture called it an octaword .

This is from people who measured time in microfortnights.

Seriously, I loved DEC minicomputers. Never used a PDP-11 much, but enough to have bought a PiDP-11 kit. Still have to allocate the time to build it. I drool over the PiDP ...

I am an on and off Twitter user.

Unfortunately, some changes made around the time Elon Musk bought it made it virtually unusable without a Twitter account.

I am very interested in your work on implementing IEEE 754 compliant floating point arithmetic for the 6800. I am also developing a C compiler for the 6800 with support for IEEE 754 32-bit floats, and my floating point library already implements even rounding using guard, round, and sticky bits ...

Much of that bit manipulation in double dabble is making do without a decimal adjust instruction. I have posted code for a number of processors for converting binary to decimal. If there is interest, I can try to find it.

The first question is do you want smaller code size or fast execution?

You are trying to print a number at NULL...

If X always contains zero,

sta (ZP12,X)

does what

sta (ZP12), x

appears to do.

If you have to vary the index, you will have to

- ping pong between the indices using Y

or

- modify ZP12 to incorporate the index

It is mostly a 6309 which can be switched into 32-bit mode. It can run up to 600 MHz.

Unfortunately, I still do not have anything distributable, especially for adaptation to different hardware.

The current effort is to migrate to a new reference platform based on the upcoming Peripheral Technologies hardware.

I had previously reported that Corsham Technologies was selling reproductions of SWTPC computer components. They have also produced a CPU board based on the 6502 to plug into the same types of systems.
