Re: 2465 Project, story so far.

Some different sizes were used over the life of the plain 2465.

U2162 was variously:
160-1994-03 SN:B010101 -> B010999 (16K)
160-1994-04 SN:B011000 -> B012499 (16K)
160-1994-06 SN:B012500 -> B021965 (16K)
160-1994-07 SN:B021966 -> on up (16K)
---------------------------------------
160-1628-03 SN:B010101 -> B010999 (8K)
160-1628-04 SN:B011000 -> B012499 (8K)
---------------------------------------
160-1628-06 SN:B012500 -> B021965 (4K)
160-1628-07 SN:B021966 -> B025239 (4K)
160-1628-08 SN:B025240 -> on up (4K)

U2178 was variously:
160-1625-03 SN:B010100 -> B010999 (8K)
160-1625-04 SN:B011000 -> B012499 (8K)
160-1625-06 SN:B012500 -> B021965 (8K)

U2362 was variously:
160-1627-03 SN:B010100 -> B010999 (8K)
160-1627-04 SN:B011000 -> B012499 (8K)
160-1627-06 SN:B012500 -> B021965 (8K)

U2378 was variously:
160-1626-03 SN:B010100 -> B010999 (8K)
160-1626-04 SN:B011000 -> B012499 (8K)
160-1626-06 SN:B012500 -> B021965 (8K)
---------------------------------------
160-1995-03 SN:B010100 -> B010999 (16K)
160-1995-04 SN:B011000 -> B012499 (16K)
160-1995-06 SN:B012500 -> B021965 (16K)
160-1995-07 SN:B021966 -> B025239 (16K)
160-1995-08 SN:B025240 -> on up (16K)

So, if you have 1994-08, and 1995-09, they are 16K, and go in sockets
U2162 and U2378.

1994-09, and 1995-09 are newer than my manual, but they
are socketed the same as the 07, and 08.

Newer should work just fine.

Hi All, I think that I have managed to find something close to the original 2465 ROM's, is anyone on here able to tell me the difference between these pairs of ROMs
Original 160-1994-08 (cant find)
Original 160-1995-08 (cant find)
and
106-1994-09 (have got binaries)
106-1995-09 (have got binaries)
Is it just a later version of ROM or is it for a different model scope ?

Thanks in advance
