The BBC made a drama, "Micro Men" (2009), about some of the behind-the-scenes drama behind the BBC Micro. As I recall, it doesn't explain the whole Fred, Jim and Sheila thing though.
Just watched it last night, it's pretty good. Though does anyone have any context for the scene with Sinclair and the 3 women in the convention? It seemed a bit out of place in the whole doc.
BTW, Silicon Cowboys is another film I'd recommend. It's about the history of Compaq.
It's a reference to the fact that Sinclair was a notorious womanizer, and his exploits often ended up in the press of the time. He was also chairman of MENSA from 1980 to 1997.
The closing scene is priceless. Clive Sinclair defiantly drives into the future on his C5, without helmet or neck support, overtaken by lorries/juggernauts:
While an amazing manual, nothing beats the original ZX Spectrum manual covers (and the manuals themselves are great too). Retro8bitcomputers [1] has an amazing selection of manuals to peruse. It's almost like we've forgotten the art of the user manual since the 80's.
It's a big improvement! There were a few errors I noticed in the original, all now fixed, and the diagrams are a lot cleaner-looking in this version too.
I literally read my real-world version of this to pieces.
I'm not sure where it is now, but last I saw it it was a mess of sellotape and ring-binder-repair stickers kept in a separate box with lost pages in the bottom.
I don't recall any other book that got quite that much mileage.
(Some detail)
Acorn manuals always had a good reputation. They usually contained a tutorial section, a reference section, clear appendices with all sorts of examples and details, and a very solid index. I haven't quite seen other manuals that were quite as good.
As a really neat example: the Acorn Midi Card manual for the Archimedes went all the way from high level "what is midi" down to bits and bytes and assembler-level API calls. As a kid, it allowed me to understand midi. Compare that to the manual for my synthesizer at the time, which really didn't explain anything at all.
I found it quite interesting that a document aimed at a musician could be so technical and obtuse while the document for the computer person was so clear and enlightening!
I understand (from a friend who was at the school at the time) that at least one of the authors for one of the manuals was a teacher at Netherhall, the school round the corner from Acorn.
The BBC Micro was the reference point for the Computer Literacy Project, so developing understanding was a key goal.
There are three memory mapped input/output areas and these are named FRED, JIM and SHEILA. SHEILA contains all the machine's internal memory mapped devices, such as the analogue to digital converter, and should be treated with considerable respect.
Same here. The manual was an incredibly readable on-ramp from total basics (hah) all the way through to the FX & OSBYTE & 6502 references at the end. (And I was distraught when my ringbinding started to unravel on the Advanced User Guide)
BBC Basic is a work of art. It exposes its underlying API for you to use in assembly so you can, for instance, use its floating point routines and data areas. And it's a very well thought out API.
Does it? My recollection is that the entry points were undocumented, and changed in every revision, of which there were at least 6! - BASIC 1, BASIC 2, HIBASIC, BASIC 4, BASIC 4.32, HIBASIC 4.32...
The inbuilt assembler was super useful, and an excellent feature, but not obviously designed for calling BASIC itself. The expected use case seemed to be that you'd use BASIC by writing BASIC code, and any machine code routines (probably created using the inbuilt assembler) would be self-contained.
(Modern readers unfamiliar with this system should compare the BBC BASIC assembler much more to LuaJIT's dynasm, which it rather resembles, than to the average C compiler's inline assembler, which it was not really much like.)
Martin "Bilbo Baggins" Freeman is in it.
