Re: Arabic

Pretty sure the intention was to supply this with the machines; I seem to recall a single large sale that we were rushing to meet a deadline for. It's weird - it looks like the rom called ARABIAN-C is what I remember working on, and the International Rom only contains the arabic font but not the scr...

Arabic

I stumbled across this today at Chris Whytehead's site, and nearly infarcted when I saw the screen with Arabic! Since he mentions that he knew nothing about it, I'll confess - that was one of mine. At the time, there was almost no customisation for Arabic in the nascent PC world and no conventions o...

Re: Software for Rom/Ram boards

Sound like a great product and poasibly the first hibernation mode. I think your right about the utility to put programs in ROM. That particular MakeRom took a plain pre-assembled binary and loaded it at a fixed address. (just to be clear, this made a single program into a language rom, not a RomFS...

Re: Software for Rom/Ram boards

I suppose 'Auld Reekie Software Products' did not go down well??! pics of fully populated & bare boards are needed :!: I guess so though just to be clear I didn't post this because I have any hope of still selling these! :-) The software ought to be usable with any board, or even emulator.

Software for Rom/Ram boards

Some years back my friend Fred King and I produced a Ram/Rom board for the BBC Micro that we sold under the trading name of "Edinburgh Software Products". Acorn User adopted it as their in-house board which gave us some free advertising, though we never made much money on it. It was a great experien...

Re: Hmm.. was there ever an 8" floppy drive for the BBC?

I guess I could do that, but I have several hundred images to unpack and was waiting until I could find a command line program that I could script to do them all at once rather than each one manually through a GUI :-/ Check out SWH's beeb perl script: https://www.spuddy.org/Beeb/mmb_utils.html That...

Re: Hmm.. was there ever an 8" floppy drive for the BBC?

I extracted the files from D1000.IMG but couldn't manage to do the same from D1000B.IMG. What kind of format is that using? Thanks DavidB and BeebMaster! So looks like everything is there that the folks who wanted to build an 8in drive need :-) Here are the basic sources needed to build a DFS rom (...

Re: Hmm.. was there ever an 8" floppy drive for the BBC?

Could some kind soul please extract the contents of D1000.IMG and D1000B.IMG from http://gtoal.com/bbc/ ?

Judging by the text strings I see in the image, that is likely our 8 inch formatter and modified DFS.

(I'm not in a position to extract files from a disk image yet)

thanks

Re: Hmm.. was there ever an 8" floppy drive for the BBC?

I have a patch for the DFS rom that supports 8in disks. Written by Fred King. Will upload it here as soon as I can get it off an old floppy image in a couple of days. Supports 77 tracks if I remember right.

Re: ROMs from Graham Toal

Another piece of software I've subsequently found (but haven't yet extracted from the floppy disk image) is a patch to a specific dfs+nfs rom, which tweaks it to support 77 track 8in disks! I suspect there are not many of those drives left around, I've certainly lost mine. If I remember rightly, th...

Re: ROMs from Graham Toal

Thanks for going through the images and sorting out what was worth posting. I've also found the source code for the unix/rs423 rom - that is a terminal rom that embeds data in the terminal stream (a terrible mix of OSI networking layers!) to implement a filing system. So you would log on to the unix...

Re: Acorn teletext adapter

I guess the original - I think it identified as "TFS"? (It's been a long time since I thought about it!) I *may* have a paper copy of the BBC's telesoftware definition document. I didn't write the telesoftware decoder though. Anyway if you can generate packets with the same content of what would be ...

Re: Acorn teletext adapter

Thanks to my old pal Harry Barman for alerting me to this thread. I was the developer who worked on the released Teletext rom for Acorn and I still have the source code on a floppy. As it happens I'm currently putting together a Beeb system with a flashfloppy so I can copy off all my old disks, thou...

Re: New version of Scramble for the beeb (going well)

Sorry I didn't know about this remake earlier - just heard about it today. Probably of no help at this late stage but I would have offered some resources - myself and another Scratch coder have both implemented versions of RocketRaid and Scramble in Scratch, and the graphics are easy to extract from...

Re: 6809 experiments

I just found this forum and thought I should drop in and say hello. I built a 6809 second processor back when I worked at Acorn (and found it again a couple of days ago when tidying up my garden shed). Anyway I noticed a comment on the lack of 6809 programmers nowadays, so I thought I should let you...
