Pi1MHz future supported devices

Post by dp11 » Sat May 09, 2020 10:54 pm

This is just for me to gain ideas of what people might like. I have a few things in the pipeline. This does not represent a promise of might come or what might be possible.

Do you think a Prisma 3 emulation would fit into your 1Mhz framework now that there is a nearly finished MAME / ACRTC emulation:

I was thinking that... but it looked like pretty much all the IO was used up by the 1MHz bus

I wonder if the Midwich hard drive could be implemented. It splits up a hard disc into 200K, 31 file volumes - ie. the same as DFS - so I think that would be good for loading SSD images onto.

Some other wild ideas:

Add more members of the family? like the Hybrid Music 2000

Network? viewtopic.php?f=3&t=16565

Video Digitiser? a Pi can have a camera

mouse ?

USB harddisk ?

I think Prisma 3 might be possible , there are a few step required before this is possible. I'm working on these steps in the background. I will need help !

Teletext how do people imagine this working ? A preset number of pages on the SDcard ( e.g. 1000 pages is only 1Mbyte SDCARDs are big !)

That would be awesome... I think. I've seen some tremendous looking screen captures in the MAME thread, but I must admit, I'm not entirely sure what benefits it brings :-? :-? Is there a lot of software / games that supports this hardware?

Not sure if I can be of any help. More likely a hindrance :lol: :lol: :lol:.

Doesn't that apply to the majority of 1MHz bus devices?

There's really only Ian's MagicImage/Wand which are excellent drawing/animation packages, and a handful of programs used in TV programmes.

Think of it as a graphics card which comes with BASIC extensions, so can be easily used in new software developments.

So, is that the Inca Jones, Snooker and Racing game that you've posted screen captures of? They look awesome.

My suggestions would be : -

1) The existing Pi1Mhz BeebSCSI adapted to use the INTERNAL 1Mhz bus.
Acorn VFS uses internal 1Mhz bus, but the ADFS files from the Hard drive are Read Only and no floppy support.
This would open up a little used port, and would be a good work around for some of the contention issues on the main 1Mhz bus.

2) Emulation of Datacentre USB Drive 5.
The existing Pi1Mhz supports Datacentre Ramdiscs 0,1,2 & 3 and adding USB / FAT file access (Drive 5) would make this facility more useable.

I hadn't really thought...but yes, if there's a store of Teletext pages on the SD card and the Teletext Adapter can fetch them like it's downloading them from the airwaves that would be good. Maybe it will also be possible to support Telesoftware.

Inca Jones and the Racing car ones are playable games although they are relatively simplistic as they were intended to be played by children on TV shows. The Snooker one is not a game, just a visual aid to a snooker themed quiz show that potted a ball when you got a question right and missed when you got it wrong.

They were all written in BBC Basic so it's relatively easy to create something graphically interesting with smooth scrolling and large moving objects.

Ideally a way to stuff packets into it from the outside world, either a serial link or network connection (though I assume the latter is very tricky on the bare metal, and no network hardware on the zero is a hinderance).

You'd have to implement an entire teletext inserter like vbit2 to build the packet stream from page files, and with static pages you'd have to pull out the SD card and update the files. If the content is static you may as well just put a 10 minute packet capture on the SD card and loop it like BeebEm used to do, but either way you lose the ability to do anything interesting with dynamic content.
