Re: Work experience BITD - claims to fame, and infamy

Good to read about that - glad you wrote it up. These stories need to be told, the good and the bad. Thanks. :) It was an interesting experience, though I probably worked a lot harder than I remember. I felt at the time that I only landed the position because it wasn't "cool" to write edu...

Re: Work experience BITD - claims to fame, and infamy

ARM, the company, in the 1990s mainly seemed to concentrate on bringing some of the sub-par aspects up to mediocrity rather than innovating. The ARM x00 MMU, fast multiply, debug capabilities, fine. I was a lot less happy with how the 26-bit to 32-bit migration, and the halfword/signed LOAD/STORE w...

Re: Work experience BITD - claims to fame, and infamy

I only did some summer work for Logotron in the 32-bit era and didn't get any juicy stories out of it, though it was interesting to see behind the scenes there.

But you're being too modest, BigEd! We want to hear your Inmos stories! :) (Incidentally, have you seen this site about Transputers?)

Re: A5000 and A7000 guide needed

There's some information in this thread. Basically, it shouldn't be hard to lift the drive cradle up and out of the case once any screws attaching it have been removed, though I can understand if you want more precise instructions.

Re: Wanted: Alpine Software titles for public release

Cyborg relies on CFS, of which there's currently no 26/32bit neutral version available. I had a quick look at 32 bitting the Module to bundle with ADFFS, which given a few days work would be possible, but might violate Computer Concepts distribution clause. I've instead chosen to extend ADFFS to su...

Re: loading UEF images into the Elk with UPCFS on EUP

I think a proper UPCFS filing system would be the way to go, though I could imagine it would be a lot of work. I can't immediately see if the memory allocations would be a problem for the Acornsoft games, and I didn't notice anywhere that might check for modified vector tables. For the MGC I don't t...

Following up on myself. :roll: I looked at Snapper, Hopper, Magic Mushrooms, Meteors and Free Fall. Snapper and Meteors seem to be more conventional in how they load their main code. Hopper, Magic Mushrooms and Free Fall have similar loaders to Arcadians but only Magic Mushrooms and Free Fall seem t...

Re: Electron Game Server / UEF JavaScript

Incidentally, Arcadians is sadly one of the UPCFS ‘doesn’t work’ games on the Elk, although it does go right through the loading sequence before crashing :roll:. If it did work, then I’d be claiming that ‘world speed record’ because UPCFS loads the entire UEF in less than 10 seconds.... :wink: If t...

Re: Turbo Cassette

Making UEF of compressed data on the fly - and inserting decompression code upfront - is totally doable! Metadata per game would likely be necessary to handle exactly what files are loaded/discarded and where the loader resides though :? I guess removing the loading screen and keeping it there migh...

Re: Electron Game Server / UEF JavaScript

UPURS is rom-based and so has a good start for its code storage but because the loader extension (UPCFS) needs to steal vectors and manage loading streams on the fly, I had to find pockets of ram all over the place in an attempt to 'hide' loader code from the incoming program. In the end, I achieve...

Re: Turbo Cassette

If you're willing to transform UEF files on the fly so that they contain simple decompression code and compressed files then you could make more savings. For example, you only need the second file in Arcadians and this can be compressed to around 80% of the original size (15 fewer blocks) with a sim...

Is there some way to port the tape data to digital storage via the Electron serial, so you can flood it back in through a modem socket or something?

Thanks for the tip! This has shaved off 10+ seconds for Arcadians.
