Hi Cloudschatze, Good points. The serial configuration of the Amiga tops at 31250, believe that to be the limit on base Amiga model (68000), on which I would actually suggest to use 19200 on PC bridgeboard not to overload the Amiga CPU with serial activity. This latter works pretty well with DOS …

Hi Cloudschatze, Thanks for your insight and guidance! You make a good point about the Amiga serial, it's indeed clocked at 31250, so believe the Amiga MIDI adapter works as a pass-through (here are the specs: https://rastport.com/products/KA12/) The catch we are encountering is: - when we start the …

Ok. Part of the mystery solved, looking at the insightful output of SoftMPU! SOFTMPU /MPU:330 /OUTPUT:COM1 -> Serial interface detected at port 2F8 (!) There appears to be some unexpected behavior in the Goldengate BIOS, when configured as: COM1 -> Amiga RS232 (MIDI adapter) COM2 -> Amiga Mouse -> …

And speaking of being sidetracked, here's yet another use-case for the MPU-232... Hi Cloudschatze and Happy New Year! Spent some time over the holidays to test these cool patched games with the MPU-232 :-) I've been testing on a somewhat peculiar setup, Amiga + Goldengate 486, which assigns the …

Btw: comparing SER38400.COM and SER31250.COM, noticed that at the beginning of the latter, we are setting the low bit of port FFEBh to 1. What's the purpose ?

Thanks, Cloudschatze!

Most of the drivers are spread throughout the pages of this thread: https://www.vcfed.org/forum/forum/genres/tandy-radio-shack/71478-a-trick-up-its-sleeve-midi-with-the-tandy-pssj A majority of Sierra, Lucasarts, and Microprose titles are covered. Some of the more-recent work isn't represented …

Hi folks, When not fiddling with the CPU, I indulge in MIDI. There are quite a few FM Towns games (mostly DOS conversion) which only support serial midi. I'm able to get them going, using the "host" connection of SC55-MKII and MU50, which is ok but sub-optimal, if you have a daisy-chain of MIDI …

Hi guys, With the help of a friend, we recently socketed a FM Towns II CX 20, and is now sporting a BL3 (PK-A486BL75). I coded all the assembly needed to turn all the features (cache / 2-3x) on and off. I can share if you like. At 2x turbo * 3x multiplier, CX20 turns into a little speed monster at …

Hi guys, I'm joining the team, to exchange some ideas and findings about FM Towns and PC emulation on Amiga :-) On FM Towns to turn Fastmode on, all we need is set the lower bit of I/O port 0x05ec to 1. mov dx,0x05ec mov al,1 out dx,al Compile in nasm with usual boilerplate, and voila enjoy faster …
