You can't necessarily judge the early hardware design decisions for a cutting-edge consumer computer in a fledgling industry with a backward-pointing lens based on today's standards. The first Mac was 128K and RAM was extremely expensive. 4mb was a lot at the start and there were many hardware...

...or just enable .mp4 for the board. ;) I think xenforo supports it.

Is there a direct upload format for video, or is video sharing only possible via external server, like YouTube or some other content host? I tried direct .mp4, but the file was not visible, etc.

Answered above. I also just attached the Dracula Happy Mac image at boot to that post. The other input I can add is that one of the residual problems with the board from 1988 was that it was not compatible with the FDHD floppies...and the logical reason for that problem is because it was based...

I ordered an XGecu T48 Universal Programmer to dump the ROMs. They should be readable. The T56 is 2x the cost and I don't think I need the extra features. The litmus test will be to read the ROMs and reprogram some replacements and see if they work. I can probably find some UV-erasable 27Cxxx...

I added dumping/archiving the ROMs to my task list and made a mental note to remember any ROM I see laying around labeled 3.0A. I have a little pile I recently discovered, but they are 3103's. The 3103 ROM was the old ROM for the stand-alone DataFrame SCSI controller boards that was replaced in...

As far as I recall from 1988, the '020 on the ProdigySE is using 32-bit addressing, as above. I created some of the initial dealer support information for the ProdigySE (and the entire SuperMac product line), and I still have notes somewhere. I'll see what's there, but the information is from...

Well...in terms of technical specs, I believe the ProdigySE uses 32-bit addressing onboard. I will see what old info I have. The limitation in the earlier Macs is because ROMBase is at 0x400000 (4Mb). And, in part, the ProdigySE solution was to replace the ROM. Interestingly (but unrelated), it...

...and so it begins... Specs: MacSE/800k Single Floppy ProdigySE 4mb board w/ PMMU and 3.0b ROM ProdigySE Software v1.5 with RAMdisk 1.29 -- maybe the latest 16Mhz 68020 with 68881 FPU and 68851 PMMU (not used unless the 8mb version) Recoverable/bootable RAMdisk Status: Machine boots and works...

Hi Zane - There was definitely some address magic. I believe the Prodigy SE takes the boot process onboard and replaces the MacSE ROM. The classic Prodigy boot Easter Egg was the Dracula Fang Happy Mac startup (indicating a modified ROM - see attached image). So, the board does its own address...

I would be curious to see a Macintosh Quilting Bee and Pie-Eating Contest. Every entrant gets a free raspberry pie!!

retro - do you need this book? 1st right of refusal. if you dont, then someone else can have it. pm me an address. free copy.

If you are looking for the classic C reference, it is: The C Programming Language, 2nd Edition by Kernighan & Ritchie. There may also be PDF/eBooks available for purchase. In general, avoid pirate PDFs/software (and pirates, in general, unless you are a Pastafarian). There are many other C/C++...

For ResEdit, download the ResEdit Docs. For programming, start with Think (LightSpeed) C or Pascal matched to your intended build machine and OS + ResEdit. C is probably the best modern starting point. Use Inside Macintosh for info about using the Mac Toolbox. Or, if you are new to programming...

I'm in a hurry...but sounds like fun! You just have to make sure you have the right tools and interfaces for the desired target machines. Think C and Think Pascal were always good. There is also the Think Reference, which is a handy toolbox reference. There were major changes between System 6.x...

Yeah...I guess it is "Killy" - corrected above in my post. The one SuperMac used was also labeled as a "Chabin" clip, I think, but that could have been the manufacturer. It came with a special gripping tool to help flex it on to the processor. Installation issues occurred because the dealers (or...

SuperMac offered 2 early memory expansions for the initial Macs. For the 128K and 512K Macs (but mostly the 512's), there was the SuperMac Enhance board. If the Enhance had an E6000 PAL upgrade on it, it could go to 4Mb. Tech Support shipped the E6000 PAL to earlier rev Enhance customers who...

Thanks, retr01! i appreciate the offer...but I definitely need to get one. I have many documents of different types. IT'S A MAD HOUSE! A MAAAAD HOUSE!!

I will work on converting these materials. I need to get a double-sided document scanner.

I found some A/UX Development docs today (loose-leaf version) and the 1.0b development tools disk. Probably enough for someone to do some damage. n.b. A/UX requires a video card that correctly implements the Video Reset control/slot call, since A/UX calls it during the startup process (and is...
