  • Converting an 'industrial' B008 back to general use

    From John Snowdon@21:1/5 to All on Wed Jul 13 01:40:29 2016
    So, I've just picked up a relatively cheap B008 from ebay - not the usual $500, a *lot* less, but it looks like one of the cards that has been used in an industrial environment - i.e. no TRAM's apart from an RS422 module, green link wires on the reverse
    of the card as well as hard wired link connector (no C004) and no IMST225 (bare solder pads instead).

    I'm hoping to turn this back in to a regular B008.

    Removing the tram and link wires is easy, but what about the missing transputer and C004?

    Is it a case of pulling out the pins from the C004 pga socket and adding back in a real chip?

    For the missing IMST225 I can add a smt plcc 68 pin socket and try to pick up a qfp version of the chip - but is there anything else that will need doing?

    Hi John!

    For a first check I would use the board as is (without T2 & C004) with a TRAM in slot 0.

    The T2 is only for the C004 configuration. For the slot0/link0 is the IMS C012 responsible.

    You will find the manual (incl. the schematics!) for the B008 here:

    Mike

    Thanks Mike, I did make a mistake in the original message - it's a TMB08, rather than an IMSB008; so a Transtech, rather than Inmos board.

    I think the TMB08 is covered in the same PDF that I got from your site for my existing TMB04.

    My hope is to make the TMB08 a slave card in a 'new' system I'm building (Harris 20MHz 80c286, XT-IDE controlled CF drive, 3c509B ethernet), and have my existing TMB04 with it's maxed out 16MB of onboard simms as the root of the system (since they both
    use 8bit transfers, I guess it makes no different which card is the master and which is slave).

    If anyone has or knows of a Helios/X11 supported display generator board, I'd love to be able to make this in to a Helios + X11 workstation :-)

    No doubt I'll post an update when the board actually arrives!

    newatw.d
    newg300.d
    newg332.d
    newgds.d
    newgds2.d
    newsplas.d

    The IMSB419 is my favorite. But the GDS2 is also great.

    Hi there

    Check out the following https://hackaday.io/project/5358-keplermatik/log/18469-trams-green-wires-and-fake-b008s

    I found this when I was looking to get my TMB08 working...

    cheers

    Richard
