Macintosh SE Accelerator boards

[Tiptoeturtle]

This was originally published in MacUser 1988 March. MacUser also provided people who asked with a standalone printed version of the report (printed on thicker paper than the magazine was printed).

The Prodigy SE is visible at the top left corner of the second page. Although this seems to be the best performer by a long way, and considerably faster than a standard Macintosh II, I think that may have been due to the circumstance that MacUser was testing it with an onboard 68881, which I suspect none of the other boards had fitted when being tested.

The testers also failed to pick up on the detail that only the Orion had a bank of 8 SIMM slots.

The Orion is visible at the bottom right corner of the second page.

Very cool, but I can't read it. Too small. :'(

Click on em, plenty big to read. I have a couple of these I think.

There were a ton of SE accelerators made. I have a couple Radius accelerator 25's that turn an SE basically into a RAM deprived (no RAM upgrade) SE/30.

This lab test article is fascinating. It includes Plus accelerators and the first generation of SE accelerators only! Nothing tested had a 68030 or provision for additional RAM. The tests pre-date implementation of the 68030 in the Macintosh IIx (September 1988) by six months. These accelerators pre-date  MODE32 (1991) and 32bit addressing by about three years.

*****AHA! For some reason I need to do a two-step magnification process. Just clicking on a thumbnail defaults to "Fit to page." When I right click I can see the "Large" option which is far more legible.

You wouldn't happen to have a higher res scan of the 2nd page would you, or a close up of the Hypercharger card? Been trying to figure out jumpers and those are different than what mine has set however I can't quite tell if the very top jumper "A" is populated.

I made a 600dpi scan of the second page only, which produced an 8MB jpg file, and uploading that 8MB file into the gallery here three times produced the same error message "Upload skipped (Error code 500)" each time - although it should have worked ?

So instead I uploaded the 600dpi second page to Photobucket, along with the other scans, which I hope can be found at:

I am not sure, but it could be that working from the top down the jumpers are:

Jumper

No jumper

Jumper

No Jumper

No Jumper

Jumper

Maybe someone with the installation manual can be found.

600dpi is not necessary. 300dpi would be much better and 1/4 or so the file size.

Also, don't forget after scanning them, to convert them to as low a bit-depth grayscale as possible. That really saves file space and you lose nothing by dumping the color.

Thanks for that, I'll play around with what appears to be the jumpers there on the page.

Came from my request. I have a Hypercharger upgrade and the manual is nowhere at all to be found, nor are other pics with jumpers. I can't get the 68881 to work, despite the extension showing it as being installed - possibly jumper related (since mine are different). Smaller res are in the
