838-Drive Select Board (838-DriveSelect)
The 838 Drive Select Board allows 3.5 floppy drives that do not have a drive select jumper to be easily connected to your computer. No more hacking of ribbon cables to get the appropriate drive number configured.
Simply connect the Drive side to the current 3.5 floppy drive and the other side to your controller via a standard straight through floppy drive ribbon cable (34 pin cable). Then it is as simple as choosing what drive number to be assigned with the dip switch.
All boards tested before shipping.
Board color may change and component colors may change depending on stock.

838-SCSI Limited Edition (838-SCSI)
This is a PRE-ORDER. The limited-edition versions have already been ordered.
Once out of stock, no more will be ordered.
Please Note: Photo shows a bare rendered board, but users will get a fully assembled and tested white 838-SCSI card.
Introducing the 838-SCSI Limited Edition White card for your TI-99/4A and Myarc Geneve 9640 computers. One of the best storage solutions brought back to life for 2024.
All limited editions come stock with machine sockets and GOLD contacts.
This expansion card has been in the works for quite some time and is now being offered to the community. The once hard to get WHTSCSI card has been reworked to remove unused circuitry and correct some board errors. This board is completely compatible with the original WHTSCSI Revision F expansion card.
Changes/Additions:
1> Removed one of the 50 pin IDC header connectors
2> A DB25 connector has been added to help allow for a more stable data transfer for IO and to address new devices that are using the industry standard DB25 connector such as the ZuluSCSI device.
3> Added a USB port for 5v power to power devices like SCS2SD or ZuluSCSI.
This card has been tested extensively with the TI-99/4A and Myarc Geneve 9640 computers. The card has been tested to function with original spindle SCSI drives, EZ135 cartridge drives, SCSI2SD devices as well as the new ZuluSCSI device.
This is a limited production run that is fully assembled and tested 838-SCSI board Limited (White board with Gold contacts and machined sockets) - There are only a handful of these and no more will be produced.
No bare PCBs or DIY kits will be sold due to previous user errors.
What you will need for your board. If using a DB25 connection you will need a DB25 male to male cable straight through, every wire needs to be connected 1-1, 2-2, etc.
Orders will be filled by first in first out.
Once out of stock, no more will be ordered.
