A few questions about the GVP Impact A500 HD8+ Series II

[sim085]

Do not want to hijack this thread, however was following it as I have a similar HD8+ and have a quick question on the ROM chip ... so buying the ROM chip offered on ebay is not enough? You also need an additional board?

TJLazah sells 4.15 ROM's on ebay:  http://www.ebay.com/itm/Amiga-4091-GVP-or-Supra-Series-III-SCSI-ROM-update-/131566171810?hash=item1ea1f476a2
