Update ahead of the Easter break
The feedback on the IECHost GUI client for mass-dumping purposes has been patchy: I got bits and pieces in terms of feature requests but haven’t managed, among other things, to get hold of Graham (the author of WarpCopy64). Therefore, I … Continue reading →

TAPClean and IECHost updates
Yesterday I implemented the custom cleaning code for “Glass Tape” in TAPClean. Before publishing an official release I will double check a few points: Adding more signatures from those tapes that use the “Glass Tape” format, Tuning “Glass Tape” pulse … Continue reading →
