Re: Electron + PiTubeDirect with Z80 second processor DIR problem?

For the interested reader, here's some context about this issue, and what elk_mode does to fix it.... Anyone who has an original Acorn Z80 Second Processor will encouter this problem if they try to use it on an Electron. Mark Haysman (Retroclinic) hit it back in 2009: https://stardot.org.uk/forums/v...

Re: Printer port MMFS boards

So it would be appropriate to include the resistor on my (but probably not Silverback KenLowe's*) board for those that choose to use grabber clips rather than the wiring mod. The resistor can go either in the Beeb or on your board - both will work. As Robin (Wheel_nut) pointed out, you get more pro...

Re: Printer port MMFS boards

Just to be really clear, then, the resistor is -purely- there for if someone isn't using the P/MMFS board, but plugs in a putative non-standard printer cable which could connect to the VIA buffer? In which case, the resistor is only useful when you have the permanent wiring mod to use pins 25 and 2...

Re: Printer port MMFS boards

I'd love confirmation from Hoglet that his P/MMFS will work on a Master with the same connections (Pin 2 on IC70 or Pin 32 on IC69). Electrically, it should work. The LS244 buffer on the Master is IC5. I'm not sure anyone has actually tried it though, and on the Master it's easier to add a second u...

Re: Problems trying to use an HP LP2065 monitor with a Master

Assuming the HDMI converter works with another TV, I think you can eliminate the BBC connection as a problem. Though BeebMaster's comments are indeed correct. Was the cable you are using supplied by CJE as well? Another possibility is the HDMI converter really does need to be connected to a HDMI mon...

Re: Turbo SPI vs Smart SPI

Richard,

I second what Daniel says, you will need to try to include two versions (a Model B version and a Master version) in the MultiOS.

The Model B version will run in the Master, but there are issues, such as PAGE being increased to &1900.

I think then Dave that you may have hit the nail completely on the head there. I definitely do not have any ROM with that code.
Many file system ROMs also contain the TubeHost code.

What ROMs do you have fitted (try to be exact with versions, or post a photo of *HELP)

Re: Turbo SPI vs Smart SPI

This assumes that the 'U' MMFS driver works with both interfaces and simply hobbles the IFEL one so that it doesn't have the turbo-speed write. This may well be a false assumption. It is a false assumption. The U version of MMFS will not work with the Turbo hardware, not even for reads. NB If I did...

Just to make sure everyone is aware - this does need a small reversible mod/addition to the beeb, to bring 5V and a clock (I think - Hoglet?) signal to two unused pins on the printer port. Not a clock, it connects the SD Card Data Out (MISO) signal directly to Port A bit 7 of the 6522, which MMFS r...

Thank you. Gonna check that out later!!
I should also point out, it's only going to work on a Master 128, as the MMFS version we started with was ADFS 1.50.

I used to use this a lot, but have stopped using it since I got a BeebSCSI.

(Pi1MHz also emulates BeebSCSI very well)
