I was working with dmemphis today in an attempt to build adapters (and power circuitry) to read the 2716 EPROM from a SuperBrain. Additionally, we re-burned some "backups" to 28C16 EEPROMs and built the associated adapter to use these in a SuperBrain.
The ROMs we read seem to be previously unarchived. I have uploaded them to my website, but we intend to get these up on BitSavers, too.
Here are the links:
http://retro.togeo.com/files/SuperBrain 4_003 VC8001.Bin
This was from a SuperBrain and was labeled as 4.003 (and displays that version upon boot)
http://retro.togeo.com/files/SuperBrain QD 3_05.Bin
This was from a SuperBrain QD and was most boringly just factory labeled with the "Intertec" logo and proved to be version 3.05
For comparison, the ROM image that is up on BitSavers at http://www.bitsavers.org/pdf/intertec/firmware/SuperBrain.bin is version 3.1 according to the boot prompt. We are not sure if this a QD ROM or not.
In another thread, user snuci posted a ROM that was very similar to our v4.003 above, differing by 3 bytes as-follows:
Thanks!
