Quite a collection and contains my first pc. It was hard to use before I could read.

I ported his 6809 Forth to the Ensoniq Mirage, a 1980s sampler.

That is great, makes me wish I still had a Mirage but mine died back around the turn of the century. Mirage was not great as a sampler but a great platform with all the software that got written for it over the years.

Ah, shame you got rid of it, they're really easy to work on.

I ported Forth across because I was trying to debug one of mine, and wanted a way to poke the chip registers directly to see what was going on. Initially I ported SBUG across to it, but I've always liked Forth and that meant I could write and run test programs easily.

They could be had for like ~$100 back then so I parted it out to rescue other synths in need. Kept the CEMs since 3328's were looked down on and just about the only CEM that was still cheap back then, made a few VCF/VCA modules/pedals that went off to other people, sold a few years later when they finally got difficult to find, pretty sure I still have one or two left. Think I might still have the bender/mod wheels, no one wanted/needed them.

Prices for them are stupid these days.

His homebrewed OS takes the best from OpenVMS. Kudos!
