Amiga 500 rev. 6A 1 MB chipRAM + 0,5 or 1 MB fastRAM possible?

[Blizzard 128 MB]

Hello.
Amiga 500 rev. 6A 1 MB chipRAM + 0,5 or 1 MB fastRAM (trapdoor slot) possible? How?
I expanded an Amiga 500 rev. 6A 0,5 MB motherboard to 1 MB chipRAM with 8375 318069-16 Agnus (PAL system, max. 1 MB chipRAM). Original Agnus 8371 (max. 0,5 MB chipRAM).

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.

I am shopping only from Europe, I live in Europe.
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.
A500+ rev. 8 motherboard 1 MB chipRAM + 0,5 or 1 MB fastRAM how possible with trapdoor card?
1 MB chipRAM + 2 or 4 MB fastRAM possible with rev. 6, or rev. 8 motherboards?
0,5 MB chipRAM + 2 or 4 MB fastRAM possible.
JP3 jumper on rev. 6 motherboard function?

A508IDE Fastmem with IDE 74 USD:

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.
