Re: [patch] Systems from the first Olivetti PCS series

My PCS now has a 4.1 GB hard disk, and Ontrack Disk Manager does its job just fine. I'm SOOOOO happy I'm really happy to hear that :D - the old HD actually killed my IDE-USB adapter (the SATA port on it is fine). They seem dangerous! The old hard disk finally wins a battle against USB adapters ;) -...

Can you program an EEPROM with the original BIOS? Because they ship an "anonymous" BIOS
Very interesting proyect
It's a clone of the IBM 5150 board so it can be fitted with all the same ROM chips, take a look here for more info: http://www.minuszerodegrees.net/5150/mo ... 50_u33.htm

Re: [patch] Systems from the first Olivetti PCS series

It seems that IDE PIN 28 was early used for ALE (Address Latch Enable) later for SPSYNC (Spindle Synchronization) and finally for CABLE SELECT. And the drives recognised by the Olivetti PCS can be jumpered for SINGLE DRIVE, MASTER, SLAVE and CABLE SELECT. Then I guess that those drives used on Olive...
