SD Computer Products SBC-100 ROMs S-100 SBC

[wave solder]

During a very long house clearance and move I found a S-100 Z80 board with two ROMs on it and I thought I would post the dumps of them here in case anyone was interested.

One ROM (2716) is marked Monitor, the other is illegible (B2758)

Thanks for uploading those - May be useful if I do discover one of these S-100 cards.
It seems CfCH do have one: https://www.computinghistory.org.uk/det/47672/SBC-100-S-100-Single-Board-Computer/


IIRC my Northstar has an S100 Bus, which might work with this card - or even the other ITHACA Audio (possibly also a Z80 one) you've posted pictures of your blank PCB of.
Although the Northstar is already Z80-based, so doesn't need an upgrade from the older 8080.

I did find this website on this SBC-100 - But, as before, is currently saying 'Forbidden' for me: http://www.s100computers.com/Hardware%20Folder/SD%20Systems/SBC/SD%20Systems%20SBC.htm
However, this website on it does work: https://www.retrotechnology.com/herbs_stuff/s_sd.html

It seems SD did also produce a VersaFloppy system to go with the SBC-100 / other S-100 systems: https://deramp.com/downloads/mfe_archive/010-S100%20Computer...py%20Disk%20Controller%20Manual.pdf
