Not exactly sure what this was meant to power, but I am guessing a hard drive?

Outputs are +5VDC, -5VCD and +24VDC

Free to anyone who can put it to good use, just pay shipping. It has not been tested.

Finally figured out what this power supply goes to. Was browsing eBay and came across this listing (https://ebay.us/m/76h9fv) which shows the same power supply. It goes to the Cromemco 8" Floppy Dual Disk System. So if anyone needs this, it's still available.
 
Sorry I can't make an offer due to tariffs etc. but I do recall this PSU from my early days at The Byte Shop in the UK and can confirm that it will happily power the Persci 299B shown in the link - attached a pic of my friend in front of my IMSAI populated with Cromemco boards and my naked 299B with the PSU just visible alongside. Given the voltage outputs it should also power e.g. a pair of Tandon TM848's - either the '-02'or the '-E' designation with a change of power connector. I have just finished fettling a pair of TM848-02's which are now running nicely in an IMS8000 S100 chassis.

I walked past the former site of the Birmingham Byte Shop a short while ago on a trip to the city. Completely changed beyond all recognition...

Indeed it is, Dave, Byte Shop Birmingham is where I built that IMSAI not long after I opened the shop. I loved the Cromemco's but Blinkenlights - what can you say :) I see you list a Nascom 2 - also one of my favourites. I knew Kerr Borland and Ken Jones from Nascom and built (and sold) a few along the way. I designed and built an EPROM programmer for the Nascom 1 and friend and I designed and built an S100 interface for the Nascom 2 primarily for memory expansion. Happy days! Apologies for the OT post, nullvalue but thanks for your post saving a Cromemco item from the trash and which has brought back many fond memories.
