Shipping to Europe 46 CAD = 35 USD. 74+35=109 USD = 102 €.
A508IDE price = 2×complete A500 config price???!! :shocked: Abnormal.
Shopping impossible.

Complete work A500 config + shipping from ebay.de = min. 70 €.
IDE+8MB expansion 102 €. But CPU = 68000 7 MHz, too slow.
Faster and better CPU 90 €, ACA500, but out of stock.
A508IDE + ACA500 not work simultaneously.
But chipRAM 0,5 MB, too little.
A500+ with 1 MB chipRAM 58 €:

Ebay.de expansion prices too high.
Simple 0,5 MB trapdoor expansion 20-30 €, 1 MB to A500+ 69 €, etc.
Unreal.
1 MB 29 USD. http://www.kipper2k.com/a500chip.html
A500+ config min. 64 €.
http://www.ebay.de/itm/Commodore-Amiga-500-Plus-/121731739651

The complete A500+ configuration (A500+, KS 2.04, 8373 ECS Denise, 2 MB chipRAM (2 MB Agnus), RTC, 8 MB fastRAM, CFIDE, min. 25 MHz 68000 or 68010 CPU, PSU, mouse, 20-30 disks, 1084S monitor+RGB cable) which can be used well is too expensive, with shipping min. 200-250 €, and no PCMCIA, no AGA.

A1200 100 €, 030/28 MHz 8 MB CPU card 120 €, etc.

The expanded A500+ price = expanded A1200 price. A1200 = PCMCIA, internal IDE, AGA, etc.
The A500 expansion = meaningless.

Happy I have Minimig and don't even think about these issues. Only wish the little one had 8MB Fast RAM on its snappy 68SEC000

Authentic for an a500 is 0.5mb chip ram.

Authentic for an expanded A500 of the time is what I meant, so only old expansions made whilst the A500 was still in production.

I saw all of the expansion here:

A Gary adaptor and wire+GAL is needed for the all 1,5, 2, 4 MB trapdoor fastRAM expansion card.

Rev. 6 motherboard 1 MB chipRAM (1 MB Agnus) + 0,5 or 1 MB fastRAM possible with trapdoor card, but how?
A500+ rev. 8 motherboard with 2 MB Agnus = 2 MB chipRAM simple. 1 MB chipRAM on motherboard + 1 MB expansion card.
I use in 2010  a rev. 6 motherboard (0,5 MB chipRAM) machine + a 1 MB expansion card.
The result: 0,5 MB chipRAM and 0,5 MB fastRAM.
A500+ rev. 8 motherboard 1 MB chipRAM + 0,5 or 1 MB fastRAM how possible with trapdoor card?
The same may be the solution both motherboards.

1 MB chipRAM + 2 or 4 MB fastRAM possible with rev. 6, or rev. 8 motherboards?
Or 0,5 MB chipRAM + 2 or 4 MB fastRAM possible only with trapdoor card?
Example:

http://www.bigbookofamigahardware.com/bboah/product.aspx?id=1015

I connected the 0,5 MB fastRAM card to the trapdoor slot (1 MB chipRAM rev 6 motherboard), the fastRAM not exist.
The J7A jumper cut (0,5 to 1 MB operation) = trapdoor slot off.
I restored the J7A jumper to the original state, but the machine did not work.
I cut J7A, A500 work. The Gary wire necessary.
Without Gary wire 1 MB chipRAM + 0 MB fastRAM, or 0,5 MB chipRAM + 0,5 MB fastRAM possible only.

I  do not want to buy a RAM expansion card, or rev. 8 motherboard. I want  to use my rev. 6  1 MB chipRAM motherboard + 0,5 MB fastRAM only.
There may not be big disadvantage, if I expand the motherboard onto 1 MB.

How to wire Gary? :confused:
