As most of you know, I provide an EPROM service to the community as "Hummingbird EPROMs". I am also a avid .bin file collector (TI and otherwise). My collection strives to reproduce the history (good and bad) in the evolution of TI and other peripheral devices as well as providing a database for the replacement of defective DSRs. There are still some notable gaps in my collection that I would like to fill with help from the community. Notably, the buggy HFDC V12 and V13 DSRs (either source or .bin), The Dijit CorComp RS232 DSR (to co-exist with the AVPC card), and any of the SCSI DSR versions. The interim (and buggy) versions provide a valuable insight into what was done right and what was done wrong in arriving at a flawless, working final product. The comparison can be a valuable tool in producing future DSR upgrades and also as an archive to preserve a part of TI history. I would like to encourage anyone who would like to share any of these (or other) DSR files to send them to my email address: Rmcarmany@gmail.com.
Miller's Graphics came up with upgrades for the TI, Myarc, and CorComp RS232 cards that allowed them to use the shared interrupt line and co-exist with the Dijit AVPC card. I have the TI and Myarc versions and am looking for the CorComp version. Does anyone have the source code or have a modified card that they could dump the DSR from? Thanks!
