I picked up another interesting machine earlier, a Micro Byte PC230. Normally I write some lengthy description of the computer including its specifications and history, but this is a new one to me. These machines were apparently both manufactured and sold in Adelaide by Micro Byte Systems. They're somewhere between an XT and AT clone, with an NEC V30 processor configurable to run at 4, 7 or 10MHz, 640KB RAM, EGA Video, a SCSI Hard Disk (WD Controller) and dual internal 3.5" floppies with a matching 5.25" external drive. The 30-Watt PSU looks to be lifted directly from an Apple II clone. This machine is pretty complete, with a matching monitor, keyboard, disks, books and even a carry bag for the machine itself. It doesn't boot, but the drive is detected correctly in the BIOS so I suspect it's just been erased. It would have been a perfect machine, except this one was built without the ISA riser fitted, so it has no card slot expansion whatsoever. Some machines were optioned with the ISA riser, and could take 2 8-bit ISA cards. It's extremely disappointing as I had hoped to install a Sound and Network card in the future. Perhaps I'll eventually find an external solution, or replicate the riser PCB, but without a schematic it's unlikely. However even as it is, it's none the less an interesting piece of kit, and made in SA. Without the sound hardware I haven't worked out what to do with it. It does appear to be capable of running Windows 3.0 according to the factory restore disks, so I'll attempt to install that first.
