It has a 68010 CPU, real demand page virtual memory, good keyboard, good screen, reasonable graphics resolution, true Unix System V (release 3.0), small & quite. I enjoy both my machines very much, and still have to see a program that will run on a VAX 750 any faster (actually the 7300 is almost twice as fast [same load] as the 750. The way to buy it cheap is this (works for me..): 1. Go to computerland / Microage / mail order / etc place. 2. Buy the 512K, 10mb machine (useless as is, but wait). 3. Make sure you haggle the price (10% off list or better). 4. Buy a 2mb memory board from Alloy Engineering (+1 617 875 6100). 5. Load system software ONLY, run some messy cpu/memory bound process for few days, test the modem (built-in), the serial port, the parallel port, etc. 6. In the mean time order a "74mbyte" (actually ~59) for IBM AT from 47th Street Photo (N.Y.) +1 800 847 4191 (+1 212 260 4415) 6a. Buy an external disk expansion box (1 full height disk) as well as two ribbon cables (female on one side, card edge (female) on the other. They need to be long enough to reach from inside the expansion box to the back of the computer. 7. Buy/steal/make two ribbon cable extentions (female on one side, male with mounting flanges on the other). One of these cables needs to be 34 conductors, the other one 20. Length of no more than 12 inches each. 8. Open the computer (2 screws in the back, 2 under keyboard's latches. 9. Remove & discard 10mb disk. 10. replace OEM cables with short extension cables, route cables neatly to the outside & mount (using flanges). 11. Close computer, carefully. 12. Connect long ribbon cables (coming from disk, inside expansion box) to ribbon cables coming from computer. 13. Boot diagnostics, if hard disk spins but will not talk to computer, you have one (or both) ribbon cable(s) installed backwards. 14. Use the format, test winchester procedures to prepare disk. (use the multi-user option of formatting (4000 blocks swap partition. 15. Re-load Unix, etc. to the machine. 16. Test Carefully 17. Enjoy in good health. As an option to the above you can buy the 3B1, pay $2-3K more and have a little pretier version of same. The only diference is in the amount of memory; the 3B1 has 1/2mb mother board therfore will run up to 4mb RAM, the 7300 has only 512K and can use only 2.5mb max (enough for me). If 2mb of memory are enough (vs. 2.5mb) you can buy the EIA/RAM board from AT&T. Buy it as .5mb board, buy 120ns 256K RAM chips mail-order, and install them yourself. Total Cost (Estimate): 7300 $4,200.00 RAM $1,400.00 Disk $1,500.00 Expansion Box $150.00 Unix foundation $275.00 Unix Utilities $450.00 /* See Note */ Taxes, Delivery, Agony $800.00 Total Damage $8,775.00 Oooops! This is more than you asked for. As a matter of fact this is more that I though (or told my wife!). But it makes for a neat system. /* Utilities Note: This will make an almost complete Version V release 3.0 (troff is excluded). You do get vi, ex, ksh (not csh, but just as good (bad)). It also gives you SV documentation, etc. */ --EOB-- p.s. If you care, give me a call or drop a note. You may even convice me to sell you one of the two I have so I can buy another toy and play some more.
