Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

A small item for the next manual revision.

25 GP19 VGA BLUE OUTPUT
24 GP18 VGA ½ GREEN OUTPUT

In the pin diagram on page 10 should be:-

25 GP19 VGA ½ GREEN OUTPUT
24 GP18 VGA BLUE OUTPUT

Another small item for the next VGA manual revision.
Page 6

"In monochrome mode the resolution is 640 x 480 however when the colour output is enabled (MODE 1) the pixels are duplicated along both the x and y axis giving a 320 x 240 resolution"

Should that be (MODE 2)?

Thanks, I thought that I had fixed both but somehow forgot.
I will have Rev 4 ready in a few days.

A bit late but I have updated the manual to Rev 4.
Just a few trivial updates.
Thanks Phil for the corrections.

Hi Geoff,
I'm confused and please forgive me if I'm wrong (again) but the manual at:

https://geoffg.net/picomite.html

appears to be called "MMBasic Ver 5.07.04 Rev 3". (not Rev 4)
Am I downloading the wrong version or has the front page not been updated?
Is there any other way of confirming it is the latest?

Cheers,

Andrew

The PicoMiteVGA manual is Rev. 4 but the PicoMite manual is dated 16/05/2022 so I think it has not been updated. Most of Peter's recent upgrades have been to the VGA so perhaps there is no need for Rev 4 yet.

Thanks Phil,
I had assumed that Geoff's comment about Rev 4 referred to the non-VGA version but I now see that you (and hence Geoff) were talking about the VGA version.
I have the latest non-VGA version so I'm happy.

Cheers,

Andrew

Just read Geoff's 'Boot to BASIC computer' article in the latest Silicon Chip.  

It reminded me of a thought I had some time ago that the PicoMite VGA has come so far that a board like Peter's could have been announced as the COLOUR MAXIMITE 1.5 which is effectively what it is.

Is it too late now?

A small item for the next manual revision.

PWM Command page 112

Minimum frequency (Hz) = (Val(mm.info(cpuspeed)) + 1) / 16777216

or ignoring fractions of Hz

Minimum frequency (Hz) = (Val(mm.info(cpuspeed)) >> 24) + 1

Hello Peter,

What are the chances of the PicoMite (VGA) getting support for:
MM.INFO(EXISTS f$)
MM.INFO(EXISTS FILE f$)
MM.INFO(EXISTS DIR f$)

?

Best wishes,

Tom

I suspect that, since you described Peter as "kranky" elsewhere, not a lot.  ;)

You may have to make an alter of SD cards and 1/2W resistors and rotate your PicoMite forty-two times while repeating  the magical words "matherp is never kranky". :)

<shrugs shoulders> There is nothing wrong with being "kranky", I often describe myself as such. He probably has me accurately labeled as "awkward" and/or "difficult", it doesn't mean we don't have a productive working relationship.

Best wishes,

Tom
