Today's Topics: Bell Labs 256K Ram Swap & Shop - Computer Equipment Wanted Status Of WorkS? ----------------------------------------------------------------------

Date: 22 January 1982 1400-EST (Friday) From: Bob.Colwell at CMU-10A Subject: 256K RAM from Bell

A friend at Bell who worked on their 64K DRAMs told me in 1980 that their 256K DRAMs were going to be ready in late 1981, so sometime 1982 sounds about right for their real release. At the time, all that was left to do was tweaking the myriad timing paths so that the chip tended to reflect a constant load on the supply -- they were very worried about noise margins and claimed that this was the major contributor.

The 256K chip will use their redundant-rows technique that Bell developed for their 64K DRAMs. (In fact, this same person told me that the 256K and larger chips were the real reason that technique was devised in the first place).

Did Newsweek really get the scoop over all of those Electronics News magazines? They knew about Libya, too......

WorkS appear to be degenerating. There is no need for long discussion on trivial and peripheral points:

1. Of course we'll want hardcopy. Paper is a marvelous medium.

2. Of course we need OCR. However, it will likely be hard to justify OCR's for individual workstations: reliable reading of free text is remarkably difficult and expensive.

3. Some things are serial-access, some are random-access. Clearly the logical interfaces to the two differ: the former is not a segment.

4. Few underlying mechanisms are strictly invisible. VM, like any other such, has its demands but remarkably little overhead for core-resident applications. Certainly, all interfaces should not be forced into a Procrustean bed, requiring all file I/O to be through demand paging.

Now, may we return the the discussion of workstations?
