Update : Money sent.
IDE68K 402 and the 68K offset boards arrived - look good and functional (need to do pins/headers) but functional as ordered. Thanks!
Declaring interest in:
1x v402
1x 8MB board
1x riser socket
PM will follow

AMike, at the moment I have one v402 with boxed(walled) ide connector, but no cf adapter.
I will be able to ship any sold items during next few days, but maybe not for a few weeks after that.
Pin headers on bottom, upto 3 sockets on top.
Attachment 125964Attachment 125965
The "ground" plane is not connected to any pins by default, so board can be flipped and rotated, and possible ground connection made then.
Place for capacitors and solder bridge connections to ground pins when used in "default" orientation.
Board not tested so far.
Price 6€, shipping 2/3€ europe/world
Interested in one of the ide boards if availiable

Also interested in one of the risers above
Particular one and only ide adapter, v402 available at the moment. Has marks of filing down molten plastic.

The riser card doesnt allow v4x ram boards in the middle.
When at the edge position, v4x ram board would cover middle dil-64 position pads, left row.

Order received! Will be testing this week. Thank you!
I wanted to post a follow up on some of the hardware I picked up out of this thread. All is well. I finally snagged a ROM switcher (a spare someone had from one of the other active threads on AmiBay), which made the setup I had in mind with parts from here (IDE68K and 8MB Module) all work in my A1000. Here are the fruits of the effort:
NTSC A1000/Rev 6 Mobo, with upper daughtercard. For reference, CPU pin 1 faces rearward/left; reverse direction and opposite side of an A500.
IDE68K at the bottom of the 68K socket stack. I believe it's the 402 - the one without the CF module slot that would impact the A1000 floppy metal - the IDE header pins are alongside the upper # pins side of the 68K. Note: I ordered mine without the IDE header and without the Int2/OVR or LED pins installed. I wasn't sure what I was doing as far as the IDE physical intrusion, or the wiring, and I wanted options. More further down.
Spirit Inboard 1000 with 1.5MB and 2 lines that run to the daughter card DPALEN - If you don't have this, several machine pin sockets are recommended if you are going the route I am taking for IDE (physical intrusion). YMMV applies. This board inserts memory in C00000-D7FFFF range.
mkl 8MB under-68K module from this sale thread. Autoconfig works fine for this application.
I have a machine pin socket in next, with a 68010 CPU in that. This saves the pins on the CPU with all the install/remove testing I ended up doing.
Modifications:
IDE68K - The IDE header - I ended using an non-shrouded 40-pin straight header (notch faces the CPU, pin 1 rearward, for reference). If I had decided to use an IDE cable, I was likely to use a 90-degree header to let the cable then naturally drape up and across the top (the hard way was also possible - solder the cable in). I chose a 2GB industrial IDE DOM module that sits vertical on that header. The IDE port power is driving it, so no need to wire a power header. Thankfully the height of the Spirit board pins raises things very high and there is a very slight angle giving me room for the PCB overhangs further up.
The IDE68K INT2/OVR/LED header pins I took the 2nd option connections at the #34/35 pin end of the board. I used 90-degree single row headers on the PCB top that work here because of the Spirit Insider is high above. Also, the hop to the 86-pin connector for signals off the motherboard edge connector is short right there. Don't go hunting for chips to solder to elsewhere (and possibly damage) - just pull out the Amiga RKM and find the correct pins and solder a header pin into each via (the signals are underside edge pins, but a large enough via comes to the top with solder that can be cleared with a sucker will fit a standard header pin). For counting, pin 1/2 is toward the mouse/joystick ports. OVA is 17, INT2 is 19, even on top, odd underside. Verify signals on the edge to the actual chips with mkl's notes and a meter (continuity). With headers in place, you can use colored jumper lines (for arduino projects) to connect to the pins - easy disconnect if you need to pull it out. I used 90-degree headers along the 86-pin, but vertical header with a slight bend inward will work.
The Spirit Insider goes in next if you have one (or similar). Long machine pin to machine pin socket - goes in nicely, just do it carefully. No modifications. It just sits a little higher. If you have concerns, support it over in the RAM/modulator can area with some non-conductive material between. Re-connect your lines to the daughterboard.
The mkl 8MB unit has a low 90-degree 3-pin header for RAM enable/disable. I had to replace it with a standard height 90-degree header to clear the IDE DOM module from the side. A vertical 3-pin header would have also worked - I just had spare cut-strip from the others I cut for the project.
The kickstart switcher is offered by Tuxbar81 - and required here with an A600 Kickstart 2.05 or 3.1 in order to Autoboot. That unit requires 3 lines run and requires removing the motherboard from the chassis to access the underside to make all modifications. Two lines get tacked to DPALCAS, and one line to RST found on the 86-pin edge done with the same kind of header pins and wire used for the IDE68K. Instructions are in a manual linked on his wall for his board for the cuts/mods, but I went beyond their scope. I put full 3-pin headers in the W1-W5 positions. I cut any existing joining traces on an individual W# header (like 2-3 had a trace between them), if present. Just remember to jumper the pins the right way to match the unnecessary cuts, then short/connect them correctly.
I used the 68010 because I had one, and the fractional performance it offers on a few minor things.
Autoboot works for both Kickstart versions I used. My 3.1 was 40.63 with scsi.device 40.5. My 2.x was 37.350 with scsi.device 37.55.
Heads up on my switcher's design: With the Kickstart switcher I have right now, the PCB sits in the 2 existing 27C256 sockets. It intrudes on top of the CIA chips immediately rearward on this motherboard. You won't be able to make use of a DF0/DF1 switcher stack module if you have the PCB-only switcher version. The currently for sale version is the ribbon cable type.
Heads Up 2: Literally, with the height of the Insider, the A1000 shield won't go back in place. At some point I plan to reduce the height of the Insider by replacing the long header pins with a shorter machine pin socket stack, and taking the CPU out of it's socket. It also seems logical to put the 8M module under the Spirit as part of the socket stack to keep everything low enough. I'll need to modify the 8M jumper to vertical to make that happen, and keep an eye on the IDE DOM intrusion.
The system is stable running 3.1 while I wrote this up. MKSoft Diskspeed numbers (ballpark) with this IDE DOM are: (defaults, rounded)
512byte: Create 80K Write/Read (both) 95K
4K: Create: 290K, Write/Read: 345K/375K
32K: Create: 455K, Write/Read: 515K/565K
256K: Create: 545K, Write/Read: 615K/635K
Files Create, Open/Close, Scan, Delete and Seek/Read values are: 30, 48, 152, 84, 218 respectively.
RSCP measured speed (635K/sec) matches an A2091/Quantum 40, but as with any IDE interface, nearly all CPU is consumed.
Hi all, who have sent private mail enquiries. I'm not sure if I can test/sell any adapters during this month.

About 68010 and DRAM board:
To refresh, the cpld uses cas before ras refresh when 68000 address strobe(/AS) is negated. I dont know if 68010 will release /AS in loop transfer mode? Refreshing can be delayed perhaps.
Definitely interested in buying one of the A500 IDE unite as and when you have any available for purchase. I would really like to resurrect my A500 :)
edit: also interested in the CF adapter to go with it

Declaring interest in 2 x A500 IDE adapters, if available
I'd like an IDE adapter if available, i assume it will work fine on a CDTV too?
I have limited quantity (a few each) 8mb ram boards and 8mb+ide solder combinations.
I've sent pm to interested in the 8MB-thread, I will be looking at this thread some time.
40€ / 80 €
includes non-tracked shipping, registered(signed for) +10.30€ or 'Expres' +15.10€/18.50€ europe/world
The ram board (v59) has config out signal. (can change to config in, must connect to ground level to enable ram, in A2000 get config in signal from zorro last slot / in CDTV from mainboard.)
CF-adapter could be used with ide. Not sure if ide board fits in cdtv.
Declaring interest in 2 x A1000 IDE adapters, if available
At the moment a few ide+8mb combo:s for sale.
IDE boards? Remaining 4 blank pcb:s left for v402. A few built with 'special' (larger/right angle) ide connectors. Maybe a few older v2xx series boards with cf-connector.
Special variations I've thought about: underside of board ,CF connector / female 44-pin right angle/ 40pin male r/a ide for cf/sd adapters/ at the A500 sideslot cover area.
This ide+ram left , 70€ with untracked shipping
The ide board is slightly bent from heat and some black at the edge.
Tested before, booting to workbench and checking 8mb ram.
Declare interest pending questions - PM'ed
Sorry - interest withdrawn

Hi mkl.
Interested in 2 board 8mb+IDE if available.
PM sent.
pm to scrappysphinx. Also from october, unbrain, dlasher, pm'd.
The ide board should fit in CDTV too, it is same height as ide+ram combo, http://www.amibay.com/showthread.php...l=1#post876390
Price of ide board 40€, Picture of one currently available posted soon to fs-thread.

Pm replied, i have agreed to purchase an ide+ram board with mkl for 80€ plus shipping on the 25th February :)
Thanks
declare interest for 8mb+ide if available
I would like a 8mb and IDE combo please. Let me know when available.
Hello
is this board easy enough to install and use on an A500? I have a kickstart 3.1 installed if that makes any difference. I’m looking for something that will allow me to make use of a CF card or a hard drive.
Memory board desc. being edited here. v59 and others.
68000 socket 8MB ram, A500/1000/2000/CDTV.
The www page for ram :http://www.mkl211015.altervista.org/ram68k/
-- older cpld code versions have bugs -Cpld code can be changed with xilinx jtag programmer
-Options v58/V59 pcb cpld code for config out or in other boards have both
-config solution for cdtv (config after dmac)
-limit memory size under 8meg
-may not be compatible with accelerator processor boards - something to fix
Stacking of boards
-Under A500 keyboard is limited space
-so separate boards that each have their own socket pins, e.g. ram and ide and cpu plugged in to a stack, is too high to fit in a500.
-space limited in cdtv
-stack of two boards should fit in a2000. a1000?
-A soldered combination of ram(v59) and ide(v4xx), to same (separate type, not the very long strips on plastic black body) socket pins (with kapton insulation tape in between) will fit.
Attachment 137445
V59 can be plugged to top side of v4xx style ide boards, but it maybe tight with the polarising tab of idc cable connector or maybe not fit with boxed ide header (ide v402/v418). v401/419/420 have 1.27mm of extra clerance to ide connector.
About dram refresh:
To refresh, the cpld uses cas before ras refresh when 68000 address strobe(/AS) is negated.
Autoconfig(tm)
RAM autoconfig will work without wires in stock A500/1000/2000 that have no other autoconfig devices - except processor cards that hide their E8xxxx access. But the ram can be still incompatible until revised.
CDTV guide: http://eab.abime.net/showthread.php?p=1233919
- other CDTV info
- config in/out, (I don't know if autoconfig usable. )EDIT: BOTH config in and OUT grounded on dmac.
-CDTV has DMAC chip that is autoconfig device
-80 pin diagnostic connector pins (is similar to a1000/500/2000 86-pin connector)
-DMAC chip pins 71,72. Grounded.

A500 has config out contact grounded, this can be cut and replaced. Some of the side slot expansions can feed its config out back to a500 side slot contact?
Amiga 2000 has config in, out on zorro slots. Could make contacts with pcb material like vero board maybe? Config-in to ram board can be taken from last zorro slot (or pin 8 of u606 74ls32 chip.) leaving the slot otherwise unused.
In V4.4 the signal should be found also on a pcb via:

Amiga A2000 version 86-pin slot has config in but not config out? B2000 version should have both. Page 94 in A500 A2000 Technical reference manual
i hope I understand his correctly, but a ram plus IDE board with CPU plugged in won’t fit under the A500 keyboard?Quote:

I believe that soldered to same (10mm pin length) pins combination of boards will fit, I will recheck this. But separate boards with own pins each won't fit.Quote:

KS3.1 (v40.063) has the needed ide driver. You need to connect two wires from ide board to a500 mainboard. The usage of disk should be the same as in A600. (partion, format etc..)Quote:
