I upgraded my Amiga last night to 1 meg last night. Thanks for posting
the correction. I would not have noticed it. Works great! I made one
mistake. I nicked the wire from pin 3 on U1H (74F138) to pin 10 U1J
(74F399) and it broke without my noticing it. It would boot under 1.1 but
not 1.2. Would crash with addmem, otherwise ran fine in 512K mode.
Replaced wire and everything was fine.
Question, why does avail give the following results when system is booted
with 1.2 and 1.1 with addmem C00000 C7FFFF respectively?
Wb1.2 Wb1.1
