UPDATE 02.06.2015:
SPLD code of FASTRAM board has been changed for CDTV and IDE68K compatibility.
Both verified working by one Amibayer.
UPDATE 12.05.2015:
I have a number of SRAM chips for the 12.625MB FastRAM board available (R1WV6416RSA-7SR).
8 euros each (2 is needed) + 3 euro shipping.
SOLD OUT (THE MANUFACTOR ONLY PRODUCES 55ns CHIPS NOW WHICH COSTS MANY TIMES MORE THAN THE 70ns ONES)
0,5MB RAM for A500 / 1MB chip RAM board for A500+
Simple to assemble, hole components only. Parts easy to source,
except perhaps the side connector (bought mine at RS).
Using same RAM chips as found in A500 rev.6/8 boards and A590's.
5 euro each
BACK IN STOCK (10 left)
Guru ROM adapter board built for easy mounting inside A590 (no cutting).
DMAC V2 is REQUIRED.
Can also be mounted inside GVP sidecar units, but some cutting is required.
Simple to assemble, hole components only. Parts easy to source.2 euro each.
Programmed PLD (own code) available for 3 euros each.
SOLD OUT
12.625MB FastRAM board for A500/500+ with accompanying Gary board.
All surface mount, contains TSOP components, very hard to solder.
10 euro a set.
Programmed PLD's (own code) for FastRAM and Gary board available (3 euros each).
Note: Its a compact cpu socket board using SRAM. The board does in
no way compete with prices for Kippers super cheap boards, but it
offers >50% memory as the ONLY advantage. SRAMs are also hard to
solder for the unexperienced, and hard to source.
The 1.7MB RAM starting at 0xC00000 is added automatically by the kickstart,
the rest is added with a few addmem commands, meaning the board
will work fine together with autoconfig sidecars like the A590 if
its internal RAM is disabled. The A590 DMA's fine to this memory.
But if you are happy with 8MB fast mem, get a Kipper board!
STILL AVAILABLE

NOTE:
The boards are sold UNASSEMBLED and WITHOUT parts for DIY people as I have no intention of
assembling lots of boards or sourcing a lot of parts.
Project files necessary to complete the boards are available for buyers or interested buyers
via PM.
Thanks for your interest.
