LMT computers zx spectrum disk interface
« on: November 08, 2017, 12:12:53 pm »
Many years ago, I was part of a team of three designing  and programming a plug in module for the zx spectrum.  Which eventually ended up with just me finishing the code.

It was called the SPD-1 Disk interface with "snapshot" button.
I have been looking for years now for anything related to this.
Has anyone got one going spare?
Even just an eprom from one or pcb?

Hi...  No I DON'T, sorry !!!!!!  :(
But I DO remember something, (similar??), for the Commodore-64, that I had, but long gone now....
It was called 'SnapShot', and was a plug-in CARTRIDGE with a red button it....
You would load in any game/app software from tape or disk, (however many modules), until it was RUNNING.
THEN, hitting the 'SnapShot' button, resulted in (virtually?) all memory compressed & written to disk !
I can't remember if it gave you an "SYSxxxxx" number to run it later, or created an 'Auto-Boot' loader for it.
Upon thinking, it must have been the 'AutoBoot', and was mainly for transferring from TAPE to DISK  :D

I'm sure I 'copied' that 'ROM' to file, for later mods/burning, but is now too long ago... sorry mate.
