You are looking at a vintage new/SEALED piece of software technology, DATACAD Version 5, from Cadkey. This is an amazing piece from 1994 that showcased what was, at the time, watershed technology to be able to enable 2-D and 3-D graphic design. Compatible with MS-Dos and IBM models (you can see all specs in the pic). This is a must-have piece for any tech historian or educator, and because it is SEALED, it will arrive to you in PRISTINE condition. GRAB THIS SOFTWARE NOW! Buy with confidence, as my response is well over 8,000…and rising rapidly! Buyer pays NO shipping and handling (shipped securely inside bubble-wrap packaging). This item ships GLOBALLY, and while this IS a “buy it now” item, ALL reasonable offers WILL be considered! THANK YOU for looking, and for your consideration of this GREAT item!
