I hadn't heard this mentioned here before, so I thought I'd bring
it up and see if it is universal or just something cute on my
system. There exists this file in /usr/bin:
-rwxr-xr-x 1 bin bin 2332 Jan 1 1970 .!.
when executed it displays the names of the designer team (?) from
AT&T and Convergent.
A question for Lenny: What is the latest information on the ICUS
upgrade? Are they still available? How much? From what address?
BTW, I've spent a few days nabbing programs from osu-cis and wanted
to say 'Thanks' in public. Your task as maintainer of the archieves
has run my UnixPC down to 2% available disk space.
I was cleaning dust bunnies the other day and finally noted the
revision level on my motherboard: Rev D. Was that one of the problem
boards with the mythical WD2010?

Was that one of the problem boards with the mythical WD2010? As I discovered during the research for the "DRUN Patch" permitting use of the WD2010 disk controller chip with *ALL* 3B1/UNIXPCs, there were at least 3 major motherboard revisions being concurrently manufactured by Convergent during the 3B1's heyday. I, too, was initially misled by the "Rev. #" sticker found near the volume control pot. One has to ALSO examine the motherboard trace/drawing reference number located near the left rear of the machine. From the docs I posted for the DRUN Patch: [...] The second "clue" was an observable pattern of which motherboard "Rev. Level" systems failed with a WD2010 and which succeeded with a WD2010, but ONLY up to a point; there were still, say, some "Rev. C" systems that would and some that wouldn't "take" a WD2010. The final "clue" was the presence of three separate and distinct system circuit schematics in the latest copies of the UNIXPC Reference Manual. System Desc. Schematic Set Originally Revision Levels S4 CPU P5 1MB D-08-00225-00 20-May-1985 A through F S4 CPU D-08-00230-00 9-Jan-1985 A through D S4 CPU D-08-00222-00 9-Jan-1985 A through J And note the "Rev. Level" are not coincident. "D" on a 230 board is not the same as "D" on a 222 board or a 225 board. Since that original posting, I've seen a D-08-00216-00 board which is really weird ... its floppy connector is completely reversed from all other boards and there's no shielding over the telephony circuitry. And there are also "stickers" placed over the "D-08-00xxx-00" along the lines of "-00236-00" and other variations along with other "Rev. #" variations. To locate the board schematic number: +--------------------------------+ | [connectors] | |X | |X | . . . . | [RAM] V| "V" = volume control +--------------------------------+ The "XX" is the board number, in copper, written vertically; it may be obscured by a sticker. Remove the sticker and re-affix it off to the side since BOTH numbers are important when seeking help. The "Rev. #" stickers are usually located near the volume control.
