I am selling a very nicely restored vintage TRS-80 model iii (3) computer that is loaded with many upgrades!
Preparing to move and letting a few of my treasures go to another collector to enjoy. There's been a lot invested into this machine, and must admit, I'll not be disappointed if it doesn't sell. Price determined by conservative valuation shown below.
Features:
Restored motherboard and caps
New meanwell power supply
Rare custom LCD video display upgrade installed using custom 3d printed mounting brackets.
Working Tandon tm100-2a floppy drive (Serviced)
Gotek floppy emulator a drive 0 and usb thumbdrive.
FreHD SD card hard drive with GoTek floppy auto boot disk (to menu to select which hard drive)
Included floppy drive images and hard disk images
Rare prototype reproduction high res graphic board option (pascal/mavric).
Working original keyboard (the left shift key will occasionally require some exercise to combat oxidizing contacts due to age, but always comes around and all were working when recently tested)
Updated io cables for high res board, frehd, and expansion (ie orchestra 90-- orchestra 90 not included)
External io bus multi connector expansion to allow plugging in up to 4 external devices.
LCD video method uses a new old stock POS display, gbs-8200, and ttl sync inverter adapter. There is some scaling of pixel edges as expected going from analog to digital. The gbs may occasionally offset screen horizontal position when auto calibrating, but still usable when this occurs, and can always reset to re calibrate.
I will include a copy of the model 3 high res graphics disk for using and testing high res graphics.
Both real floppy drive and gotek usable. Gotek with flashfloppy firmware. Goteks for trs-80s require hfe images. Thumb drive includes free tool required and instructions for converting dsk or dmk images to hfe. Real floppy motor spins during gotek floppy access for familiar real disk sound.
Can boot gotek floppy, or use gotek autoboot freehd disk to launch frehd hard disk menu and select bootable hard disk. Cannot boot from real floppy drive (in position 1), but can copy real disk to disk image on gotek to boot in future.
Thoroughly cleaned and refurbished. Ram tested and bad modules replaced etc. Great condition with minor wear from normal use. Some scuff and scratches. Great overall condition. Everything tested and working when recently tested.
While upgraded, still selling strictly as is without warranty, guarantee, or returns due to vintage nature.
No original manuals or original box included.
Will include supporting files/documentation for the upgrades included.
This is about as good as it gets for enjoying these upgrades and not having to make them yourself :)
