Later BASIC versions introduced the CHAIN command specifically to solve this sort of problem; you could mark the data that you wanted to preserve using COMMON. I think some Microsoft BASIC versions may have also supported COMMON together with MERGE. But these things might not have been merged into the mainline BASICs yet.

Very little of any of these files is dated, but going by the dates that I do have, this was probably released in an e-zine in either February or March of 1978, although work on it may have been completed as early as December of 1977.

DOGE's good twin: MR. DOGGE, who doesn't hang out with Big Balls but BIGTREK.BAS.

LATE NOTE:  THE EXPERIMENT WITH MERGING TWO OR MORE MODULES HAS BEEN TRIED. I
AM SAD TO REPORT THAT THIS APPROACH APPARENTLY DOES NOT WORK. IT SEEMS THAT
THE EFFECT OF THE 'MERGE' FUNCTION IS TO DESTROY DATA (IN ADDITION TO CERTAIN
LINE NUMBERS). MY THANKS TO MR. E. DOGGE FOR THIS INFO. E.D. ALSO SENT A 'TRIM-
JOB' OF 'BIGTREK' CALLED 'TREKMOD'; IT PLAYS THE SAME GAME, BUT LACKS THE 'SCO-
RING' AND 'VISUAL' FUNCTIONS. NOT TO DEMEAN MR. DOGGE'S EFFORT, I CAN'T PER-
SONALLY SEE HOW THIS PARTICULAR 'STARTREK' CAN BE MEANINGFUL WITHOUT THE SCO-
RING ROUTINE. IF THIS WERE MY 'BABY', I WOULD (IF NECESSARY) REDUCE EVERY BIT
OF (TEXTUAL) CONSOLE OUTPUT TO A 2 DIGIT CODE SO AS TO RETAIN 'SCORING'; THE
'VISUALS' ARE CUTE BUT NON-ESSENTIAL. SEE WHAT YOU THINK. ALSO !!! THERE ARE
(IN THE 'BIGTREK' FILES ONLY) SOME CRUCIAL ERROR TRAPS WHICH I INSERTED. LOOK
FOR THESE AT THE BEGINNING OF THE 'NAVIGATE' AND 'IMPULSE' SUBROUTINES. THE
COMMON STARTREK PRACTISE OF INPUTTING A '0' WARP-FACTOR (DISTANCE) TO ABORT
AN IMPROPERLY ENTERED NAVIGATION ROUTINE WILL, WITHOUT THESE TRAPS, GIVE YOU
A 'SUBSCRIPT OUT OF BOUNDS' ERROR, AND THE GAME WILL HAVE BEEN (LITERALLY)
LOST. I SUGGEST COPYING THESE EXACTLY IF YOU WILL BE TRYING THE 'TREKMOD' IM-
PLEMENTATION.

I have found that it is really hard to get pixel perfect results when trying to create classic System 6/HyperCard windows using html/css when working with Safari. It is SO OPINIONATED about dithering certain things that are pixel perfect 1-bit pngs and about rounding the corners of form fields.

I switched to using svgs to make a fill for my pinstripe title bars because of the dithering and inserting
-webkit-appearance: none; into CSS to strip out styling of the form fields. #retrocomputing #hypercard

I've been coping with a lot recently so decided to treat myself to a little something, The Spectrum:rainblobderpy:​, a 2024 console based on the original 48K Sinclair ZX Spectrum from 23rd April 1982, rubber keys and all. Like 2018's Spectrum Next this machine updated the firmware to a modern standard of presentation, and include modern ports for power and connectivity (1xUSB-C, 5xUSB-A).

Reader, I'm delighted with it. I've already had a bash at Horace Goes Skiing and it all came flooding back...how bad I was at Horace Goes Skiing.

Not only that but seller included a 16Gb USB that held hundreds of Mb of other speccy games - possibly
all of them easily sourced from fan sites and less reputable channels - which you can access and play through the console's main menu. That's a catalogue of over 9000 titles NOT including the eye-openingly fantastic Homebrew games made by fans in the decades since. See you in 2201? 😁

It''s a lovely sunny Friday evening out there, so of course I've spent it in the kitchen tearing my hair out over what I'd planned to stream tonight...

Which means we'll instead be taking a look at the DEC Rainbow (finally!); join me in an hour (1800 BST) at twitch.tv/baljemmett and we'll give it the ol' once-over.

Second live auction box of the day, this time it’s from the other side of the UK 8-bit war, a Sinclair Spectrum, not just any Speccy though a toastrack - the short lived 128k update to the Speccy+ invented in Spain and reimported back to the UK just before Sinclair was sold to Amstrad. I might get a repo box so I can protect this original one #RetroComputing

I spent the entire day yesterday playing with old Linux distros again.

Where I started: Debian Slink running on 86Box.

What I tried: Debian Slink and Potato on QEMU.

What I discovered: QEMU was much faster for CPU tasks (like 10 times as fast), but oddly slow with disk access. I couldn't get sound to work and X would only run at low resolution. VNC worked fine though.

Where I ended up: Debian Potato running on 86Box.
