Here's a list of current DEC PDP-8 Omnibus family (8A,E,F,M) compatible hardware sources that may be of interest. Instead of waiting for the item you need to show up on eBay, check this list. Some items may be 'in-stock', but most of them assume you know how (or are willing to learn how) to submit the PCB files to a vendor, source your parts, construct (and debug) it yourself.
32KW RAM board for Omnibus - based on the Stefan Lafferty design
MI8-E M847-extended-version-V1.1 - allows selection of 15 different boot or test programs from SW switch
32K Memory+Bootstraps for Omnibus - above two (32K & MI8-E) boards combined on one quad board
DK8EA M882 AC Real Time Clock - no DEC or SP chips used. Only 74xx and 74HCTxx series chips
- works with RX01/RX02 emulator as well as DEC drives
RX8E M8357 RX01 / RX02 floppy controller - no DEC or SP chips. Only 74xx and 74HCTxx series chips are used
TA8E M8331 TU60 decassette controller - no DEC or SP chips used. Only 74xx and 74HCTxx series chips
VC8E M869 Point Plot Controller - no DEC or SP chips used. Only 74xx and 74HCTxx series chips (works w/ M885)
VC8E M885 Point Plot D/A converter - no DEC or SP chips used. Only 74xx and 74HCTxx series chips (works w/ M869)
Omnibus - USB interface - High-speed KL8-E compatible serial I/O (with enhanced instruction set)
Please let me know of available Omnibus compatible (quad or hex) boards that I could add to this list (or any corrections).
