Just remembered a couple more oddballs I've got knocking around in the back of the house:
- Signetics Model I - Assembly language device with an integrated LED character display. I bought it because I used to work for the company that Signetics became - Philips Semiconductors.
-Commodore Colt, PC-10 III - These are actually x86 architecture, so I wouldn't usually be inclined to mention them but for the fact that they're Commodore-manufactured PC's . I think the PC-10 may be a 286. It has a hard drive in it. One of these days I'll probably dust it off and load up MS-DOS 5 and Windows 3.0 (yes, I have shrinkwrapped copies of both). How's that for a classic Dosbox ?
