Rename RAMSTART to SYSVARS It's more descriptive this way. Also, I'll soon add a new HERESTART config. 2020-06-29 08:49:30 +10:00			`RS_ADDR 0x80 - CONSTANT SYSVARS`
Move 8086 assembler from B730 to B30 Also, move doc to doc/asm.txt. Also, fix the pcat recipe which was broken since the overlay change. I hadn't noticed it because I didn't have to rebuild the MBR. 2020-09-22 09:23:33 +10:00			`30 LOAD ( 8086 asm )`

Add word TICKS Adding a delay such as the 20ms one we have in AVR programmer's initialization routine is tricky without a word like TICKS. This implementation is highly inaccurate, but more accurate and reliable than a "ballpark" DO..LOOP... 2020-09-26 07:31:06 +10:00			`445 461 LOADR ( 8086 boot code )`

Move most of the high layer of comp core into the low one With KEY and EMIT being switch words, most of the high layer can be defined before drivers. In addition to this change, I've compacted core blocks which were becoming quite sparse. 2020-10-29 09:06:58 +11:00			`390 LOAD ( xcomp core high )`
