MACSIMM - Programmable ROM SIMM for Mac SE/30, IIfx and IIsi

Submitted by GG on Thu, 05/25/2017 - 18:46

MACSIMMThe Mac SE/30 was the fastest of the classic compact black and white Macintosh computers. It featured a 16MHz 68030 with 68882 FPU and a 32-bit memory interface and supported, albeit not officially, up to 128MB of RAM. Unfortunately the SE/30 ROM contained some old code that used 24-bit addressing making it 32-bit dirty. Many classic computer enthusiasts make their SE/30 32-bit clean by installing a Mac IIsi ROM SIMM. These are nowadays quite rare and difficult to find.

GTERM25-A01 - DB25 Active SCSI Terminator with diagnostics LEDs

Submitted by GG on Thu, 11/10/2016 - 22:59

A new version of this project is available here

GTERMActive termination is required to get newer higher performance drives working on vintage computers. Unfortunately both the Amiga and older Apple computers use a DB25 SCSI connector which makes finding a suitable terminator quite difficult. GTERM25 solves this problem providing a high performance active terminator with a DB25 connector and SCSI diagnostic LEDs.
