< 1. What is the difference between a MicroVAX, VaxStation, and a < VaxServer? Everything or nothing depending on model. generally the vaxserver/microvax have no or minimal video. Vaxstations are the higher end video console. < 2. How desirable are these 3100-30's? That is, is there software < available, or are there any undesirable traits-- e.g. hard < to upgrade, can only hold xx amout of RAM, etc? Popular. the rest I cant answer as they are as unPC as they come. the disks are SCSI and ram is simms(maybe oddball though). Generally VMS runs in 4mb but 8mb or more is desireable, with 12mb it sings and 16mb is the max. < 3. What kind of display does this use? CRT/Keyboard, or terminal? Varies from a serial terminal to high end color graphics. <4. How do I tell the disk size, memory size, etc? Test 50, show device, show mem at the >>> prompt. < 5. What would be a 'reasonable' price (just a ballpark figure, < I don't wanna spend $500 on a box that could be had elsewhere < for $50). NOT $500! free to 150(loaded). The monitors are worth more than the systems in some cases. I'll be selling a few Vaxserver3100 M10es 12meg ram and RZ24l Disk(245mb) for $60 at MIT FLEA with VMS 5.5 (nolicense but useable for single user and the DECUS license). This model has no video and uses a regular terminal (I'm selling VT320s for those that may need). < 6. Anthing else I should know before committing time/money? depends on what you know of VAXen and the operating systems that run on them. (VMS, Ultrix (some not all models), NetBSD netboot, hopefully scsi support soon). Allison
