Thanks - I reached out to them. It should help provide some more info. At least one of them has a Rev B RAM Card...which is good, because I was sure I remembered them using zip RAM...and they did.

Theoretically, it can go to 32Mb...but might need alternate parts (PAL, Gate Array, etc.)

I may have the actual manual around somewhere. But...page 23 is not too hard to read. Below is the text across the truncated lines. that demonstrates the techniques of the Prodigy line of enhancement products working knowledge of 68000 assembly language All segments are in MPW format...

Are you using the Freeware/68K version of IDA or do you have the Pro version? ...and I thought the SE ROM was in the 256K bit (27x256, etc.).

I think I still have RAM Doubler and maybe Virtual PC somewhere.

I'm not sure exactly how much of the ROM the ProdigySE/Prodigy 4 integrates, except to say that it, at least, replaces the boot code. The bin file is on MacRepo, so you can check it. The User Manual also has interesting programming and architecture notes. Prodigy displays a custom splash screen...

There are artifacts posted on MacRepo for the ProdigySE, including the User Manual (that had helpful coding tips in it (with the Prodigy's variant of classic programmer hex sig tagging -- 0xDEAD 0xFACE 0xBEEF 0xCAFE), the floppy disk image components/image and a dump of the 3.0B ROM (with the...

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++...
