Probably you are the first person typing on a keyboard with
a dual AMD 5.6 Ghz, instead of one equipped with an 8 bit micro.
You can type so much faster ;-)

I had the standard ROM, a modified ROM and a bank of RAM all switchable

Mostly I was impressed with the subroutine which reads the data from the
tape recorder. The ancient programmers did a beautiful work.

Some softwares used to XOR their code with ROM when loading for the
obscurity and the copy protection reasons. So any modification to the
standard (c)1982 ROM was a potential compatibility problem.

The Basic ROM of the Spectrum is impressive (I've got the book "the
Complete Spectrum Rom Disassembly" somewhere). But it's not nearly as
impressive as the ROMs on Acorn's BBC Micros. They have got things like
multiplication tables overlapping with character code tables or even
executable code to squeeze out a few extra bytes. It also had an
operating system that was *way* ahead of anything else in the small
microcomputer market in terms of its flexibility and expandability (the
first versions had only tape recorders for storage - yet the system was
designed for plug-in enhancements with disk and network file systems).

I used to have a C compiler for my Spectrum made by Hitec - is that the
same people that make modern embedded C compilers? (I also had Forth,
APL, and the amazingly slow "Snail Logo" for my speccy.)

The 8-bitters are probably in the keyboard and mouse only. Other
abovementioned stuff is ether brainless or uses stronger CPUs.
Ah, one more 8-bitter: the 8042 embedded in the chipset.

BTW the 16K ROM BASIC of the original Sinclair Spectrum-48 is a real
masterpiece of the assembly programming. One can see the style of the
true artist. The TRDOS and BASIC-128k are just crap compared to that.
