OK - it looks like it is a MacDTS (Developer Tech Support) sample derived from the IIsi (so 1990ish or later). Also, it looks like the EgretWakeup.p file is missing from the archive, but it probably showed a single call, passing seconds. Just hard-code it if you want to use it - quick and easy...

I repaired the MPW files for you. Always use a binary format for cross-platform compatibility - don't use .zip of raw mac files, don't use .sit, etc. -- use .hqx, etc. All of the online sites like garden and repo drive me crazy based on trying to download and migrate to emulation via Windows...

Yes - sorry for omitting - I was in a hurry and my statement was not exclusionary. Thanks for adding the extra note. I actually own a 4mb MacPlus and should add it as a revival project thread. However, SE's are far superior, provide a much better baseline development experience in terms of the...

Yes - just install SheepShaver with an OldWorldROM -- should work fine. I run it under Windows 11. It's not the most intuitive setup, but there are online guides, etc., to get you past any uncertainty -- also other Mac users here. I installed it under Windows 11, so can't help too much.

If you really want a retro MacPlus experience and would like to learn Pascal instead of C, Turbo or LightSpeed Pascal might work (but different from C, of course). Alternately, MacSEs are relatively cheap ($50-150) and go to 4Mb. Otherwise, don't worry about the Mac and just install SheepShaver...

Nice - I have an original Spigot board from '92.

Schlumberger was an early player in ATE (inheritor of Fairchild's ATE business) and Factron was a circuit tester that could analyze fully-assembled PCBs for faults - the ROI was production/RMA salvage vs scrap. I was in the ATE space for a while. I think we made some Schlumberger test boards...

I think it supported up to 32Mb, but in practical terms, I don't think anyone ever went that high because of cost. Also, the Rev A RAM modules were originally made by Scientific Micro Systems, but they declared bankruptcy in 1988. Subsequently, SuperMac underwent a management-led buy-out to...

Here is a summary of my testing so far to track down the RAMDisk app hang: System 4.1 / Finder 5.5 System 6.0.5 Notes A. Old Mac SE, 4Mb, Old ROMs, IWM, 800K Boots Boots Stock Config, Sees all RAM B. Old Mac SE, 4Mb, New ROMs, IWM, 800K Boots Boots Sees all RAM C. Old Mac SE, 4Mb, New...

I tried using the ProdigySE in a "reloaded" SE config with new ROMs, SWIM and 800K drive on an older 4Mb SE board, and it seems to power on OK, but hangs as soon as I put in a disk. This symptom was the same whether I used SWIM or IWM. Has anyone else seen this kind of issue in a non-accelerated...

With the ROM programmer, I was able to read and verify several identical AM2764A PROMs (that used to run in an old SMS SCSI controller).

Here are the basics for my board: U3 ROM ID: 1002813-2001B (3.0B) U13 Gate Array: 1002812-1B U26 PAL: 1002809-1B U27 PAL: 1002806-1A Board Rev: C RAM Card Rev: A RAM Card Size: 4Mb (specifically labeled) PMMU: Yes S/N: 1974167 Status: Working (except that the RamDisk software crashes - hoping to...

Attached are the ProdigySE RamDisk Release Notes from December 21, 1987. They have interesting info about hardware configurations. Also attached are some quick facts about the Prodigy SE from the SuperMac Dealer Support Stack for use by then dealers and Tech Support.

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...
