What do you need to complete an a1100?
Some old components are not easily available, mostly custom chips from Commodore:
FAT AGNUS 8375
This is the 2MB Version. Supported part numbers are:
- 390554-01 (PAL)
- 390554-02 (NTSC)
- 318069-10 (PAL) VBB note 1
- 318069-11 (NTSC) VBB note 1
- 318069-12 (PAL)
- 318069-13 (NTSC)
- 318069-14 (PAL) VBB note 2
- 318069-15 (NTSC) VBB note 2
Donors are A500 Plus or A600. Some retailers have had them as NOS.
Other part numbers are not really 2MByte parts but replacement parts for older machines with 1MB of chip or different pinout (A3000) and are NOT compatible.
In DIP 48 format, of course. All revisions are known to work.
DENISE 8362 – OR – HR DENISE 8373
Both versions are compatible (in DIP48 format). Hires Denise (8373) really doesn’t make a difference in ECS Amigas having a flicker fixer.
2X CIA 8520
In DIP format too.
optional DB23 (female) connector
This is the connector where you plug an external disk drive or an external gotek. You can probably live without it but it fills the hole on the back of your A1000 so It’s nice for completeness. We are trying to source this connector, who knows…
MC68020RC/RP16 or faster
We have sourced a small amount of these but you can provide your own. RC/RP is the ceramic/plastic version with 32 bit address bus in PGA format.
It runs quite fast with the onboard fast-ram but you can omit the 020 completely if you provide an accelerator card on the 150 pin slot.
optional KICKSTART ROM
You need the 16 bit (single chip) version for A500/600/2000
1.3 is NOT compatible1.3 works perfect too!
- 2.04 works but doesn’t boot from IDE (Gayle)
- 2.05/3.x is OK, including 3.1.4
AND NOTHING MORE!
