Monitor test program on ROM?

Post by CanonMan » Fri Jan 25, 2013 11:03 am

Hi everyone

I know there are programs available for producing test patterns for monitors, such as those on the Watford Electronics diagnostic disk, but has anyone ever produced a similar program on ROM?

Failing that, is there a utility that would allow a BASIC program to be burned onto ROM with a bootloader that would move the program to the correct place and execute it?

Cheers,

Dave

Sorry, I have no idea about that....

I know for a fact that the Micron EPROM programmer has the facility to do just that but whether or not there's a utility that can create a ROM image suitable for saving as a file rather than blowing to an EPROM I don't know.

Isn’t there a type of ROM file that acts like a read only cassette and the OS loads the stored file just like it was on tape, that is to say, it serial loads (copies) it from ROM to RAM?
Or am I mixing this up with another computer that also used ROM carts?

Yes, that's what the Micron EPROM programmer software does AFAICT.

I'm sure that there's a routine in one of the ADT ROMs that makes a bootable ROM image for cartridge use. May have been an ABR utility . . . ? Sorry no time to check for you this evening as we're getting ready for holidays (in this weather :roll: :? )

Hope that helps, anyway.

i had two BITD, will have to search for them, sure it was by BeeBug mag :?

yes, the RFS, Rom Filing System, thats what Electron carts like Hopper, Snapper & Starship command are on :wink:
You can make your own aswell, will also have to find the proggy :roll: . I blew 4 eproms BITD for my elk plus1 on Master carts with DDDenis, ChEgg, Super Pool and munchyman 8)
just typed : *ROM (get into RFS) then CH."pool" etc

And Space-Shift-Break does *RUN !BOOT from ROMFS so with a CFS/RFS-only Beeb you can set the keyboard link to autoboot and it will boot from RFS. Alternatively, create an RFS ROM with a bit of code at the start that selects RFS and puts */!BOOT (or even *EXEC !BOOT) into the keyboard buffer.

Code: Select all

I think I saw somewhere a RamFS which used SWRam and wrote RomFS compatible images (Though maybe I was wrong about that last part) anyway, it allowed you to create FS images which could then be saved on disc or kept in battery backed SWRam.

Problem is I'm sure it was a mag (Probably Acorn User) I read about it in, and I no longer have my collection. I was never an Electron user but I've found this link from EUG where Sprow talks about something similar...

http://www.acornelectron.co.uk/eug/50/a-ramf.html

It seems that might achieve what you are talking about, perhaps?

Thanks for all the suggestions. Plenty for me to have a go at, once I get a spare moment :)

Cheers,

Dave
