Discussion about the Korg PolySix synthesizer

Hi all,

Merry Christmas!
Yes, the 8051 is a superset of the 8048. As far as I remember only the
8048 user flags are different and had to be emulated with the much more
powerful bit ALU of the 8051. I created a header file with a number of
macros to assemble 8048 code with / for 8051. The reason was I was
making some code for the 8048 and I had a simulator for the 8051. By the
use of a macro-capable assembler I could assemble 8048 code directly.
I was using the "Telemark Cross Assembler". I used it for other CPUs
as well, e.g. Z80. And for a self-made (in an FPGA) CPU, since it is
easily expandable/adoptable to other CPOUs...
I uploaded it to the files section of the list under the "Software &
Plugins" category.
