838FDC SMT Prototype testing

Описание: Project Status November Update

#1 - FPGA replacement for WD1772/Ajax is working perfectly thanks to VxRetro in solving timing issues with our weird way of polling on the TI99

#2 - My design of in-circuit flashing of the DSR is working perfectly, no more pulling eproms or worrying of corruption due to faulty battery backup, now in the field updates to DSR can be performed by the user easy and simple, to upgrade or downgrade at will, allowing us to roll out new features and support.

#3 - Finally, File Date/Time stamping on all your floppies files thanks to the onboard RTC.

#4 - Limited Sub-directory support on floppies as well as per the original HFDC specs.

#5 - Native support of reading and writing of MS-DOS type floppy formats on your TI99 system without running external programs.

#6 - Shift838 has reworked the new 838FDC to use SMT chips now, which will help reduce overall production cost, making the product more affordable to you when it's available.

#7 - Final testing underway in getting 1.44mb High-Density working smoothly at 36 sectors per track on both physical 3.5" and Gotek devices.

More News and Updates to follow from both Shift838 and GaryOPA, in the meantime enjoy this quick video showing off the new SMT board with successful formats via DM2k, DiskU, DM1000 & Disk Manager 3 cartridge.
