[HECnet] DS10 memory

[Zane H. Healy]

How close do you really need to be on the DS10?   I've used some fairly out of spec RAM in my PWS 433au, and I believe even the RAM in my XP1000's is out of spec.   Though the best is probably the old AlphaStation 200 4/233, in spite of what what the DEC spec's say, you can use 128MB 72-pin SIMM's (if you can find them).

The memory in a DS20E follows the same specs as the memory that fits in a
DS10.
The DS10 won't accept higher density modules. The DS20E has 16 memory slots
and supports memory boards up to 256 MB.
The DEC supplied memory boards offer very little information but my DS20E
also has a few Toshiba boards:

PC100-222-620R
32M x 72 SDRAM
100 MHz   CL2   ECC

The (128 MB) Micron board partno is: MT9LSDT1672AG-10Eb1

This is 100 MHz, synchronous, unbuffered, error correcting memory.
It operates at 3.3 V.
The CL 2 latency spec is important.
