I'm not sure that I would consider myself an OEM; but I have just finished
talking to representatives from Inmos, Parsytec, and Transatec about the
T9000 (and other things) and I can perhaps summarize the impressions I got:
(1) A fully functional T9000 including the virtual channel capability
will be ready around March 1993. This will not be a 50-Mhz part, but
will run somewhere around 25-40 MHz. The link speed should still be
100 Mbits/sec (this part doesn't make too much sense to me but that's
what I was told!). The price should be around $600.
(2) The 50 MHz T9000 should be out around September 1993. The price should
be around $900.
(3) The C104 (32x32 multiplexer -- the T9000 equivalent of the C004) won't be
out until June 1993. In the meantime there is an 8x8 implementation as an
ASIC (C103) -- this is either available now or soon; I did not pay too
much attention since I doubt that I will use it.
(4) The C100 (T9000 link adapter) should also be available early in 1993.
(5) The software to develop T9000 code will be first available for SUN
platforms. The IBM-PC/DOS version (the one I'm interested in) should
be out three weeks after the introduction of the T9000 -- i.e. around
April 1993. Unlike the older D705 and D7205 this will (also?) run on the
host processor (486 for example). Of course you will still need a link
adapter card on your PC bus to download the code to the target
transputers. A 50 MHz 486 should compile and link OCCAM code a bit
faster than a T800.
(6) Parsytec expects to have deliverable T9000 products by June 1993 --
the specific item I asked about was a T9000 on a VME bus. Judging
by the delivery dates above it doesn't look like anyone will have
any products before this date and even then it will be with the slow
T9000.
This information is somewhat discouraging and I would be more than glad to
find out that things are not so gloomy. Along with the other Transputer
faithfuls I will probably end up waiting for the T9000 until *whenever* it
comes out; but for now I am forced to use another processor for a contract
that must be completed by August 1993. I will be getting a number of
Transatec's i860-T800 modules ($7500 a pop for an 860 with 16 MByte DRAM,
and a T800 with 4 MByte DRAM). This is definitely not my first choice but
it's the only product that can do the job *now*.

Seems the T9000 is too late to be very useful. WHAT IS STATUS OF THE GENERATION AFTER THE T9000? Almost ready? 4 or 5 years away? Never? I have not heard anything about this except for some very preliminary discussion by David May at a WOTUG conference. Seems that the decision to invest time/effort/dollars in using the T9000 depends to a major extent on what follows (and when). Fred

I am not commenting on availability, I just wanted to clarify something.

On the T9000 the links and processor speeds are determined indepentdently. There is no reason why a 25 Mhz T9000 should not have 100 Mbit/s links. Remember, all transputers are clocked at 5 Mhz, whatever the speed of the processor/links. T800 transputers are available at 20/25 and 30 Mhz, all of which support links running at 5/10/20 Mbit/s. -- Roger Shepherd, INMOS Ltd JANET: roger@uk.co.inmos 1000 Aztec West UUCP: ukc!inmos!roger or uunet!inmos-c!roger Almondsbury INTERNET: roger@inmos.com +44 454 616616 ROW: roger@inmos.com OR roger@inmos.co.uk
