The assembly code was stored in a REMark statement, the first line of the program. The second like would jump into the BASIC program storage area. The reserved words were all tokenized, so 'REM' was just one byte at memory location 16513, and 16514 was the first byte of the comments - your assembly program!

It had this horrific modal interface where you had a 6 row, 4 column keypad (actually, two 3x4 keypads that locked together). Every button had four possible values, denoted by color, and you'd press a special button to cycle the cursor through the colors until you found the one you needed. For example, suppose the top-left button had "A (red)", "B (green)", "C (yellow)", and "D (white)". To write the word "CAB", you'd hit the toggle button until the cursor was white, then you'd hit the top-left button. Then, you'd toggle until the cursor was red and hit the button. Finally, you would toggle until the cursor was green and then hit the button.
Of course, that only meant that it took longer to fill the 63 byte memory.
It was a total letdown. I'd begged my parents for months to buy this so that I could learn to program. I think the box cover had a spreadsheet and some physics formulae on it, and I fully expected to be balancing budgets and flying to the moon in no time.
By comparison, I was ecstatic at the unbridled power and possibility of the ZX-81 (with 16KB RAM pack!) that I got for Christmas the next year.

We all would write FORTRAN programs to run on this machine, and of course we would try for the holy grail of finding out the password on the "MFD", the "Master File Directory" ... you see, each directory could be protected by a password but there was also a system subroutine called GPAS$$ (IIRC) which would obtain this password in a form suitable for going one level down. Which I think was called "attaching" to the directory. Going the other way however, was nontrivial....
We typed our stuff in using some 1200-baud terminals which only worked with capital letters, so all our code got this dense, brick-wall, appearance, what with FORTRAN requiring things to start in column 7. The only 9600-baud terminal was the graphical Tektronix one right next to the machine room; this was to be used sparingly for nongraphichal purposes lest its screen wore out. Apparently, this terminal screen operated on a principle similar to an analog storage scope, flooding the phosphor with electrons. That thing was FAST though. It also allowed lowercase characters, but the compiler didn't like those, which made for interesting debugging sessions on the other uppercase-only terminals. This is probably where I got into the habit of starting loop indexes at J. I looked too much like 1...
I learned a lot of computer details on this thing, stuffing text into INTEGERs two by two characters, and experimenting with left- and right-shifting them... The characters were like ASCII but with the 8th bit set, the interface was basically 16-bit with a 65536-word addressing limit, and this could be extended for programs with big data using some compiler switches, -32R and -64V and similar. Of course we did have to try and find out what were the limits, how far we could go with lists of INTEGER*4 size prime numbers or electronic component matrices before it overflowed or our program crashed.
AFAIR, no-one ever managed to take the system completely down. And the MFD password was revealed at one point, but as a result of social engineering, not cracking...
Now for the second computer, that was a Commodore PET, and the third, which was a Commodore 64, both of which ran BASIC with line-numbers and two-letter variables. After having become used to writing fairly structured FORTRAN, having no way of partitioning things into functions with local variables felt restrictive... I never became a fan of BASIC in this form, and by the time BASIC had shaken off its linenumbering shackles, I was already done with Pascal and having discovered the UNIX workstations they had at the university, learning C. These things were more in the same league as that old PR1ME system and C certainly was a lot nicer than FORTRAN.
Of course, a student in the 80s couldn't afford anything that ran UNIX, so I learned Pascal and practiced C on the fourth computer I had and the first one I actually owned, this was a 4.77 MHz IBM XT Clone from 1985.
I still got that one, it still works, and I power it up occasionally, just to feel the factor of 700 or so difference in processor speed.
C64 powered central heating (Score:5, Interesting)
But back in the '80s, my Dad set up the home with the central heating controlled by a Commodore 64. It was custom software on external tape, with different programs for summer and winter. The software controlled 10 zones, 7 "rooms" (the hallways in the house counted as 1 room for instance), 2 towel rails and the hot water. The C64 was wired, presumably via a com port, to relays which controlled the oil-fired boiler being on or off, and valves on the hot water pipes.
Each room in the house had a temperature gauge and a radiator, a dial for manual heat setting, and a switch to toggle between manual and comuter temperature control. The c64 was programmed to set to heat certain rooms at certain times of the day, to ceratin temperatures. The hot water could be turned on easily too, via software or via a pull cord in the kitchen. The TV out that the C64 gave was connected to the TV cabling in the house, so you change to a channel on the tele in the lounge or a bedroom and see what rooms has heating on, and their tempatures, times heating was due...
By the time the system was done, it had a custom UPS as lived in the middle of nowhere, and power cuts were frequent. Reloading the C64 was a pain, so my Dad sorted out a battery backup system. It could run the C64 for a good while, but when the batteries died, so would the C64. And without the C64 there was no heating (without grovelling into a way cavity to flick the valves mannually).
I moved out in 1996, but since then my parents have split up and the house has been sold. But AFAIK, the system is still going strong. It was when my parents moved out in 2001. That C64 must have had monster uptimes thinking about it....

My first computer was a Signetics 2650 [cpu-museum.com]-powered system I built myself in late 1976/early 1977.
"What's a Signetics 2650?" I hear all you young fellers asking
It was a Philips (yes -- they actually had a brief fling in the CPU business way back in the late 1970s) chip that ran at an astonishing 1MHz
Initially this system had 512 bytes of RAM memory and a 1MB ROM cutely named "PIPBUG". For its day, this was actually a pretty powerful processor which offered a whole lot of really cool mini-computer-like instructions such as serial I/O (110 baud), advanced memory addressing support (post/pre-increment, absolute, indirect, indexed, etc).
I also built a glass TTY (terminal) to communicate with this "computer". The TTY was ultra-cool because it had 16 lines of 32 characters (all upper case of course) and a *real* QWERTY keyboard. Yes, I was the envy of all my peers who were still flipping toggle switches and peering at LEDs hooked across the address/data lines.
One of my first software projects was an assembler for 2650 code -- hand coded and hand assembled. It was about half-way through this project that I realized 512 bytes of RAM wasn't going to be enough -- so I splashed out on 4 of the amazing new 2114 static RAM chips that had just been released. Wow -- these offered 1/2Kbyte of static RAM on a single chip (1K x 4bit) so now I had 2Kbytes of RAM and I was sure that nobody would ever need more than 2Kbytes of RAM
I managed to get the assembler into a little over 1KByte and then realized that I needed some long-term storage -- just in case the power went off. Keying in a thousand hand-coded bytes of assembler as hex characters on a QWERTY keyboard was not fun.
More late nights and long hours resulted in an NRZ tape system based on a cheap cassette deck. Once again I was the envy of all around -- since they were still using crappy and unreliable audio cassette decks with FSK modulation. My NRZ system was very reliable and had the potential to run as high as 1200bps -- woo hoo!
I was also probably one of the world's first over-clockers and managed to get the 2650 running at an astonishing 1.8MHz out of this chip that was only spec'd to 1.25MHz. This was great because it meant that the normally sloth-like 10 characters per second interface between the TTY and the processor then lept to an astonishing 18 characters per second - that's less than two seconds per line of characters!!
Despite its very limited capabilities and unbelievable crudeness, I probably had more fun with that computer than with any other I've owned or used since.
I can recall spending many, many hours hunched over that keyboard and screen, and all the non-geeks who dropped by to see if I was still alive were astonished by little marvels such as the text-based games I'd recoded for it.
Who remembers:
Towers of Hanoi
Number Guessing
Wumpus
etc, etc.
Before retiring the hardware I also wrote a simple BASIC interpreter that fitted inside the now massive 4Kbytes of RAM I'd upgraded to.
And, to give Philips/Signetics credit where it's due, when I eventually moved on to the 8080 processor I was gobsmacked by the crudeness of its instruction set in comparison.
And these days kids start bitching on boxing day because they've already clocked the latest PS2 or Xbox game -- ah, they don't know what they've missed

My first programming environment in college (circa 1996) was an old RS/6000 running AIX that the entire Computer Science used. The last year I was in college we opened it up and it was an RS/6000 with a 33 MHz processor and one 2 GB hard disk, which was the bomb in the 80s when they bought it. Our first assignment wsa to write a page of text using VI. I swear I was so confused, you type CTRL x-s to save the document and CTRL to switch out of edit mode and use ijkm as your cursor. What the hell? That took some getting used to (I was a pro actually). What was notable is that it took turns compiling C++ programs in the lab. We would type in VI and compile Unix programs on the command line, everyone would have to wait while the queue of compile processes went away. I remember upper division students compiling their work and we would go have a cigarette 4 floors down and walking back into the lab and no one had compiled yet.
This was great practice on crappy hardware so programming on PII 233 machines in JBuilder was like playing a video game. You could actually type normally wihtout using VI commands. That was such a relief. Now having a 2.2 GHz P4 is like playing with an XBox.
