#SEGA did very few computers. The #SegaSC3000 was based on their first crappy console, but actually had one of the best #BASIC around. Then I realized the #SegaMarkIII , which has excellent graphics, could still be extended as a computer with the SK1100 extension and the only compatible version of the basic. I was able to create a 2 ways basic source to wave tape format converter, and find the trick to inject #z80 cross assembler binaries through basic. So, basically, i have a computer version of the #SegaSMS but with 60hz display. Also with #katakana keyboard and charset , for which i did a utf8 converter. #retrogeek #retrocomputing
