More stuff from outta the garage
A new IIsi 50MHz accelerator with the adaptor for the upgrade. You got a IIsi that needs a boost??. This MicroMac is the part you need. $30.00 for both parts shipped in the lower 48. Reply here or PM or e-mail me at macinsane@gmail.com
If it works in the IIsi, then it works in an SE/30 (not everything does, the nubus adapter, for instance, might have worked, but it faces the wrong direction)
Sorry to say... but... who would want to boost a IIsi? Neat machine, I guess, but a bit anemic on the memory... using it for the SE/30 upgrade is the way to go... (YES I am completely obsessed with SE/30s)
