Hi all. I try to connect SE/30 and iMac 2017 via serial connection using next components: - mini DIN 8 to DB25 mac modem cable (bought on ebay) - DB25-DB9 converter - DB9-USB serial controller At SE/30 side I tried to use ZTerm with different speeds (19.2-115.2). At Mac side I tried a lot...

Thanks all for the replies! I had an experience (15 years ago) for coding gouraud shaded 3d engine for Amiga AGA with 030 and 060 processors. Yes, I did it on a similar way - drafting algos on C and optimizing that on 68k asm. Does anybody knows if Think C supports 020-030 opcodes in its...

My target is to try to code a simple 3D-engine with C-code framework, but all math routines should be written on 68k-asm.

As I read, Think C doesn't has a full assembler compiler. It is only supports an inline "asm" inserts in C code. Retro68 is a very interesting project. But I am a newbie at 68k Mac development, so I cannot understand how to use (and where to get) classic Mac OS C-headers and libraries (object...

Does anyone knows a good assembler (with 020-030 support) and C compiler for classic Mac OS? I want to code at both languages simultaneously.

Good idea. I will check this tomorrow

Today I checked all lines that going to FDD connector on PCB. I used a scans of official Apple schematics. No one of the lines are damaged. I also removed a bourn filter from PCB. But still my SE/30 can't format 1.4 and 800k floppies...

Same problem, very strange situation with SE/30...

Today I recapped a motherboard of my SE/30 - computer started working better, now I can hear a sound from a speaker :) But FDD still can't work with 1.4 diskettes...

So the only solution will be the motherboard replacement?

Hi all. Recenlty my FDD stopped being able to format 1.4 floppies. But 800kb formatted perfectly. I tried to: replace FDD from my Classic II replace FDD cable clear small puddles of electrolyte around capacitors on motherboard Computer correctly determines the type of diskette, so sensor...

Do anyone have Midi Quest synth editing software for old 68k macs? Thanks.

I opened Mac today and saw a leaked electrolytic glue around the capacitors. So I will try to clean motherboard by first.

Yes, because: 1) it worked perfectly before 2) Mac OS show this floppy by using "PC" icon

Hi. Around one month ago SE/30 worked perfectly. Two weeks ago I purchased some floppies with old software at ebay. I tried to copy/install software from they but all of them contains disk errors. Afters this I tried to copy files from my MacBook Pro to SE/30 via USB FDD. MacBook formatted...
