Hello all 
This One of a kind TRS80 Model 3 started life as a Basic 16K Cassette machine.
No hardware (brackets or electronics) were present internally for any upgrade options so using Tandy drawings I had some custom brackets made for the Drive assembly tower.
Added an additional Power supply unit to power the Drive's and Fre emulator and installed an original Radio Shack Disc Controller PCB.
Installed the additional 32K DRAM and a 48K RAM Badge
Two 720K each 3.5" Floppy Drives have been cascaded to occupy the one full size drive bay, these are awesome as creating Floppies on a PC suddenly became much easier.
This Model 3 also contains an FreHD Emulator which basically gives this machine full Hard Disc capability using SD Cards for storage, it can autoboot multiple Operating Systems by user selection straight from the HD, or you can boot from the floppy drives or even load a cassette lol.
The SD Card slot has been extended and SD cards are inserted from the back of the machine, (see pic)
Hard disc Read and Write LEDS have been mounted on the front floppy bezel very tidily..
The SD card has been preloaded with Operating Systems and some very classic games, digitised speech on the cassette output is quite cool for 1977.
Cassette cable Included
I really did enjoy redesigning and building her, the man hours gone in have been phenomenal but I was adamant it was going to be perfect, and she is lol...
The ole girl was on most of the weekend at Wolverhampton and she behaved perfectly.
Asking £320 ono Collection preferred but we can look into courier options too.
