Definitely could mirror address ranges in the Teensy 4.1 - I have done so. Just need to be cautious of ranges which DOS DMA's data to and from. When this...

* I wonder if there's any way to track DMA calls. Of course part of the point is that the 8088 is out of the loop... Well, the MCL86+ can...

Fixed! Thanks, -Ted ________________________________ From: Michael Engel Sent: Friday, April 3, 2020 1:31 PM To: MicroCoreLabs/Projects Cc: Subscribed Subject: [MicroCoreLabs/Projects] Bug in RISCV_C_Version? (#4) The comparison operator for "BLTU" in...

Did you create FIFO cores using the Lattice IP tool?

Thank you for finding this bug! Code updated.

The Teensy 4.1 may be short a few GPIOs which are on the cartridge slot, but maybe this could be overcome with a degree of multiplexing. The bus interface code...

I ran ZEXALL while simulating the MCLZ8 and another Z80 core which passes ZEXALL in lock-step and looked for any difference in any register or flag. It took over 12...

I wonder if this could be a C compiler difference between my MacBook command-line C and the Teensy C. I definitely got ZEXALL to pass 100%, but this was running...

As a quick test, could you try changing this variable to 32-bits? uint16_t temp16=0; change to: uint32_t temp16=0; ________________________________ From: MicroCore Labs ***@***.***> Sent: Wednesday, May 3, 2023 1:11 PM...

This change should not have made rrd/rrld begin to fail. You are getting weird results. ________________________________ From: hlide ***@***.***> Sent: Wednesday, May 3, 2023 5:13 PM To: MicroCoreLabs/Projects ***@***.***> Cc:...
