Abstract

Madge Networks commissioned The Tolly Group, as part of its broader “Network Interface Cards – Beyond Performance” research program, to evaluate the Madge Straight Blue 16/4 MC adapter with the main focus on documenting how the card compared with industry norms in practical enterprise deployment areas beyond raw throughput. The report examines four factors that affect real-world ownership and operational fit: compatibility with existing hardware and software, ease of installation and configuration, technical support, and network management capabilities.  

The December 1994 Technology Spotlight identifies the Straight Blue 16/4 MC as a Token Ring adapter supporting 4 and 16Mbit/s operation on the Micro Channel Architecture bus. Tolly notes that this profile is an addendum to a larger six-month NIC study that covered more than 20 adapters across Ethernet, Token Ring, and Fiber Distributed Data Interface topologies and across ISA, EISA, MCA, and PCMCIA form factors. In that broader project, cards were evaluated not just as connectivity devices, but as products whose support model, manageability, and installation experience could materially affect enterprise deployment outcomes.  

In the features matrix on pages 2 and 3, the Madge adapter shows broad software support. It supported NDIS 3, NDIS 2 for OS/2, NDIS 2 for DOS, and NetWare 4.01 and 3.11 server and client environments. Tolly also notes that Madge provided a list of supported software products and a list of PC systems in which the card had been tested. Ease-of-use findings were mixed. The Straight Blue 16/4 MC included a diagnostic utility, but it did not include an LED status indicator or an upgradeable ROM. The report also notes that Madge did not ship an automatic installation utility with the adapter, although major network operating systems already provided installation support for IBM TRPOIC-compatible adapters.  

Technical support and management were notable strengths. The matrix shows toll-free support, weekday phone support, no-charge basic support, on-site support, extended support, and worldwide technical support, though not weekend or 24-hour support. Madge also provided BBS phone information, current driver access, update tracking, supplementary tutorials and patches, modem access at 14Kbit/s or higher, and CompuServe forum support, though no World Wide Web server. On the management side, the Straight Blue 16/4 MC supported DMTF, SNMP, and IBM LAN Network Manager, though not proprietary management. Overall, the report presents the Madge Straight Blue 16/4 MC as a broadly compatible and well-supported enterprise Token Ring adapter with strong management integration, offset by fewer convenience features in installation and hardware status indication.
