[ebay][uk] DEC AlphaPC 164SX

Unread postby johnnym » Sat Jul 15, 2017 9:00 am

There's currently a DEC AlphaPC 164SX (product brief, technical reference manual) (not mine) available from Ebay UK, located in Warrington. With CPU, but no specs mentioned.

According to the seller:
Working when bought but not tested since.

I'm surprised as to how different the board layout is compared to my AlphaPC 164 (no suffix).

IIRC PC164 use FPM (non-EDO) 72-pin memory while 164SX and 164LX use 168-pin SDRAM.

Yes, the PC164 uses 72-pin FPM. Any other differences you know of?

According to the AlphaPC164 product brief it uses a different chipset (i.e. the 21172 chipset instead of the 21174 chip) and also a different CPU type: a 21164(A) instead of a 21164PC (the Wikipedia article about the Alpha 21164 gives details about the differences).
