Title: Memory Testing - Service Proms Post by: sfbaytech on September 08, 2011, 06:30:44 AM I have a couple of sick E1's here with symptoms that make me want to test the memory. Does anyone have images of these eproms they could upload or send? I do have an old programmer that can deal with these. The only other solution looks to be getting a Z80 ICE and hooking it to the system. Thanks, Chris ----------------From the web---- Service PROM's To enable the Emulator I to be serviced E-mu Systems created a number of programs on 1 Kbyte EPROM's, so that the microprocessor could run a different program than the usual boot OS. To make these work you have to replace the boot EPROM with the appropriate service EPROM, and then switch on. The Emulator Disk Alignment EPROM enables the diskette drive to be calibrated. The Emulator Memory Check EPROM enables the RAM to be checked out without needing the RAM to run the OS.

Could you take a picture of your workshop for all us gear-geeks on here?? :P |
