I must go back to investigating the Electron PSU. As capable as it is, it’s working way beyond its design specifications. So a replacement, I think, would be appreciated by users who like expanding :mrgreen:

Re: Which Gotek for a Plus 3?

I’d visit Mark at RetroClinic. He can provide you with a ready Gotek. Either email him or visit his eBay shop.

If you want to add the Gotek as a second drive you’ll need an adaptor which you can pickup from Dave H. He also has some other upgrades for the Plus 3 like ADFS with PAGE at E00.

Re: Just bought a Plus 3 and problems

Gotek is the best way to go. Dave H on this forum has an adaptor to add a Gotek as a second drive and has a version of ADFS with PAGE at E00 (useful for games that need more memory) which plugs into the Plus 3.

I’m 99% certain that it doesn’t work with SCSI - But I’ll double check tomorrow for you.

The advantages, for disc drive operation is the ‘bug’ fix and some on-board utilities.

I don’t know how familiar you are with using a Gotek drive, but you have to select\load the disc image on the Gotek before you use the Electron disc commands.

ADFS PRES with SCSI code - BeebSCSI

I saw this information today about ADFS for the Electron:

Code: Select all

ADFS 1.0x is for the Electron
ADFS 1.1x is PRES ADFS for the Electron with SCSI hard drive
http://mdfs.net/System/ROMs/Filing/Disk/Acorn/ADFS.txt

Does PRES ADFS 1.1x work with BeebSCSI and are there any advantages over Acorn ADFS 1.0?
