Design files and associated documents for download: TRS – 728 Model 1 clone – the complete project doccument ROM images and firmware PCB Gerber files
Erratum: Jan – Uploaded a corrected version of the project document. Part of the technical description on page 80 pertaining to the MCM 6670 is rewritten as I had erroneously stated that this part had 6-bit, not 5-bit words. Also found and corrected a couple of typos. Viewed in my browser, I had to hit “refresh” to clear the old document out of cache and load the new.
Following on from my done and dusted Commodore PET – 2001 (clone) , this is my second project to recreate a classic 8-bit machine from the beginning of the personal computer age.
