Default Re: Alphatronic PC rejuvenated

Yes it was made by Triumph Adler. Unusually for them it had a Z80 in it rather than an 8080.

However they removed most of the advantage in having the Z80 because the bios destroyed the contents of the index registers thus meaning CP/M programs could not use these registers.

I modified the bios not to destroy these registers as well as adding improved screen handling.

I used it to write lecture notes on many years ago!
